Global Temperatures Are Close To 11,000-Year Peak
ananyo writes "Global average temperatures are now higher than they have been for about 75% of the past 11,300 years, a study published in Science suggests. Researchers have reconstructed global climate trends all the way back to when the Northern Hemisphere was emerging from the most recent ice age. They looked at 73 overlapping temperature records including sediment cores drilled from lake bottoms and sea floors around the world, and ice cores collected in Antarctica and Greenland. For some records, the researchers inferred past temperatures from the ratio of magnesium and calcium ions in the shells of microscopic creatures that had died and dropped to the ocean floor; for others, they measured the lengths of long-chain organic molecules called alkenones that were trapped in the sediments. From the first decade of the twentieth century to now, global average temperatures rose from near their coldest point since the ice age to nearly their warmest, they report (abstract)."
If only we could figure out how the cave men managed to make the earth cool off for the last ten millenia...
I thought we were still technically in an "Ice Age" that started about 2.5 million years ago.
We're at perihelion now, already where Earth is at its hottest. In a few hundred or thousand years they'll welcome global warming... if global warming hasn't killed everyone by then.
We're at the worst possible place to add to the warming.
Free Martian Whores!
Temperatures were higher than today for 2,800 of the last 11,300 years! Clearly we're all about to die if we don't ban SUVs!
These studies only show what they do because most of the world's scientists are funded by the anti-oil lobby, who have so much money that the oil industry find it difficult to compete. Imagine if you were on an environmental archaeologist's research salary - that's got to be in the tens of thousands of dollars a year, why on earth would you accept the measly hundreds of thousands of dollars that the oil industry can afford to pay their researchers?
(That's sarcasm, by the way.)

Second reaction: We are so screwed
After spending a significant amount of time studying the data and politics surrounding this issue, I concluded that global warming is a baked cake at this point (no pun intended) The US contains a little over 4.5% of the worlds population says Google yet we are responsible for the majority of world emissions. Now consider that we are trying to cut back, meanwhile China is rapidly industrializing, increasing its footprint with every passing day. When you think of the footprint China will have when it is as industrialized as the USA, any hope of avoiding serious global damage is tiny at this point.

We're preventing the temperature decline that would lead us into the next glaciation. And like another poster mentioned, we're still in an "ice age" but we're toward the end of one of the interglacial periods. If we heat things up enough maybe we can get out of the ice age altogether. ;-)
Burn baby burn.
As a Canadian I completely support the global warming movement and am always glad to see reports like this showing its' progress.
GO WARMING GO WARMING IT'S YOUR BIRTHDAY, GO WARMING!!
At least we can take our hockey sticks on the plane now
“He’s not deformed, he’s just drunk!”
Articles like this can be scaremongering with misleading titles for headline purposes. "Warmer than 75% of the last 11,000 years" means that is has been cooler than about 2700 of the last 11,000 years. This of course can turn around and bit you when your trying to do something for political gain instead of scientific gain. After all it's all too easy to point to something like this as proof that things aren't as bad as they have been in the past pre-industrial era.
I'm not taking sides on this issue, what I'm arguing is that people need to let science do the talking and leave politics on the wayside. The result of failing to do so is that otherwise perfectly sound science research gets tainted by politics. More science and less politics please, that is all.
Title: Global Temperatures Are Close To 11,000-Year Peak
Actual first line: Global average temperatures are now higher than they have been for about 75% of the past 11,300 years
Some peak - it's barely in the first quartile.
Which would be a relevant comparison if we weren't concerned with the effects of and on human civilization, which arose about 10,000 years ago.
Yeah when we discuss global warming I think it is a great idea to ignore the fact that the Earth was much warmer before the Ice Ages. Yeah we can all agree there was some event that helped put the earth into an Ice Age but why hasn't anyone ever asked if It was warmer here before the Ice Age wouldn't it be almost natural to expect the Earth to gradually return to what it was before the event before man was here to supposedly create a problem we refer to as "global warming". Almost like a spinning top a slight jolt can cause its motion to be erratic but it eventually rights itself? So again the model is Really Warm (dino era) >>>>Big Event makes it cold>>>> gradually the earth is returning to what it once was. IMO it would probably do this with or without us. We just want to pretend that since it is better for us the way it is now that this just has to be how it is supposed to remain forever
And 6000 years ago, the temperature was at the highest level in 6000 years.
Convert all coal fire plants to LFTR Nuclear reactors. It will end up being as cheap as coal, even cheaper in the long run when you account for longevity of the converted plants which will increase the age from 25 years to 80 years. Stop worrying so much about feeling bad over whether its man mad or not, really who cares, the fact is as a species we should care about what makes our species have the most prosperous environment to live in. Forget for a moment about every other species on the planet. Let's be selfish, worry about us. Convert the plants to LFTR reactors get 1000 years of the most power dense, low waste solution while we have it available. Doesn't pollute large areas of land (one mountain pass has enough Thorium to last us 1000 years at 100% of US consumption for everything...every last Watt we use! Has less than .01 % waste that only lasts for 300 years and it consumes the long term waste at the same time. The power density of Thorium is a 1,000,000 ...thats 1 million times the power density of coal. It has none of the draw backs of other alternate energies and the nuclear reactors made with liquid salts can NOT melt down...That is no Fukushima, NO Chernobyl No Three Mile Island. IT is in no way possible with these reactors. It is a clean solution and doesn't pollute and like other alternative energies it works 24 hours a day. I have even worked out a method to pay for it, that only has a 1 year investment associated with it. COAL to LFTR
Well, that is wonderful news since about that long ago was the 'end' of the last ice age when temperatures were so low we were having massive die offs due to the cold climate.
Warming is good for life. You might not be acclimated to it but the reality is when we have periods of cooling we have die offs and when we have periods of warming there is an expansion of species, of biodiversity. The Earth has been much warmer in the past and that was good for life.
I welcome warmer temperatures. It has been too cold in the last thousands of years.
All this fussing about warming is ignoring the real problem. Global Warming is just a distraction from the real issue of toxic pollution.
Great news. We have an 11,000 year solar cycle then, right?
No, 22,000. This is the upswing. You forgot to include the down-swing.
Slashdot's rate-of-post filter: Preventing you from posting too many great ideas at once.
just googled it because I wanted to know what the hottest temps were within this 11000 year period. results http://goo.gl/FpzFH .....Some news sites are using this same data and claiming it to be hotter than it has been in the last 11k years....... The people that want us to believe the lie that is MANmade global warming know that perception = reality. If they can spew enough lies and claims it does not matter if they are actually true. There are idiots everywhere that will believe it.
ok, this stinks of troll, but I'll take it:
"So calm the fuck down about religion, deniers, AGW, man made causes, SUVs, smug ass Californians, and Al Gore. Just realize accordingly, spend less money on ski equipment and more money on boats."
I dig your cool complacency, and actually I kind of agree. Global climate change probably won't make much of difference to your life during your lifetime, and maybe not even to your kids. Because you're rich. You can afford to pay 50% more for food (as agriculture is disrupted): the worst that will happen is you might move house, accept a slightly lower standard of living and bitch about the price of things. Oh, and 'buy more boats'.
It's the poor who will pay. I don't mean the middle class, I mean the 1 billion+ people who live on less than $1 a day. They will starve in greater numbers and die in greater numbers - they can't move, or "buy less ski equipment". I get that you don't care about that, but I hope that as a society we can bring ourselves to give a shit.
'This writing business. Pencils and what-not. Over-rated if you ask me. Silly stuff. Nothing in it' - Eeyore
Except for this fact.
The *rate* at which temps have gone up over the last 17 years is 0. Which I assume makes your entire claim worthless. If it was caused by humans it would have contineud to accelerate, so your premise is wrong and the only "logical" conclusion is that it can't be human caused by the reasons given. Either Gore's hockey stick is right and temps kept climing, or its a lie and temps haven't increased. Now we have the facts of his prediction and they were wrong.
Hypothesis->Observation->Theory overturned. Its called science.

sudo make me a sandwich
The middle class will suffer too. If you currently live in a coastal city, you're going to have to either move (expensive) or fund flood defences (expensive).
The cited statistic is enough to mock this report. It's warmer now than it has been 74% of the time in the past 11,300 years. Seriously? WOuldn't that mean for 25% of the past 11,300 years the average temperature was HIGHER?! WHat makes the current temp so noteworthy? Because it is above the average, but below the highest temperature in the past 11,300 years?

Here's why you should care:

"When information is power, privacy is freedom" - Jah-Wren Ryel
Well, ten thousandish, but who's counting?
I'm so sick of snow.
Yes, the planet is heating up, time to figure out what to do next.
All this bullshit about blaming us for warming up the planet. Whether we have directly done this, or some natural occurring change has happened, its irrelevant.
Bottom line is, yes lets stop living as an excessive society. If we can make technology that don't pump pollutants or excessive CO2 into the atmosphere then lets do it. Don't do it to "Save the Planet" do it because it its just about being state-of-the art. Like, how about we stop exploding hydrocarbons in mechanical devices invented 100 years ago so that only 5% of the available energy is used to move us towards a drive thru. I think we can come up with better ways to propelling ourselves forward that doesn't involve exploding something.
Second, yes, if you live on the coast you are going to have problems with rising sea levels and super-storms. Deal with it. Don't build cheap flimsy buildings next to the ocean, and if you can't afford to strengthen you home, then move. Katrina and Sandy are a beginning, not anomalies. All those people wanting a nice view when they wake up in the morning need to wake up and realize that view will try to kill them one day. I'm tired of people bemoaning when their house got washed away when they choose to live below sea level. 99% of the country is not on the fucking coast.
Third, don't worry about the fucking polar bears. The polar bears only came into existence 600,000 years ago during the last ice age. They evolved from regular black or brown bears to deal better with falling temperatures and long term snowy conditions. Times change, animals evolve. Lamenting the loss of a species that evolved to survive specialized climate conditions that are changing is just stupid. Yes, they evolved, God didn't put them there for us to tend to and coddle.
Lastly, we will not destroy our planet. Sure, conditions for human survival might make it more difficult in the long run, and I am sure that as pressures mount from having 7+ billion people vying for a better quality of life might eventually wipe us out from global war, the bottom line is the planet itself has survived far worse then us. Plants and animals, and eventually another evolution of a dominant intelligent species will probably happen several more times over the next few billions years until the sun blows up and nukes the plant forever more. But the idea we will turn our planet into Mars is just laughable. Think about it, what plant doesn't like warmer weather and more CO2?
Everybody grab a towel and don't panic! Its just a warming planet. Its been warm, its been cold, it keeps going and going.
I haven't thought of anything clever to put here, but then again most of you haven't either.

"Global average temperatures are now higher than they have been for about 75% of the past 11,300 years"
Good?
I thought we were all burning to a crisp in completely unprecedented temperatures in human history. 75th percentile doesn't frighten me. The assumption of 100th percentile at the end of the century hardly seems terrifying either.
To quote (aproximately) Dennis MIller on Global Warming - "Look, I love my kids, I'll love my grand kids, and I guess I care about my great grandchildren, but after that, f__k it - I don't care."

The big problem with this is that we're warming up while we should be going into another ice age.

1) Cherry-picked data alert: when someone picks a data set of "11300 years" it suggests Cherry-Picking. Why not 10k, 20k, 50k years? Does that not 'fit' the message?
2) from the article:
"...After the ice age, they found, global average temperatures rose until they reached a plateau between 7550 and 3550 bc. Then a long-term cooling trend set in, reaching its lowest temperature extreme between ad 1450 and 1850...."
So let's see, after an ice age it warmed, then it reached a "low temp extreme" and now it's high? Hm, almost like it's cyclic.
Again, it's obvious from http://en.wikipedia.org/wiki/File:All_palaeotemps.png
There is a 'pulse' of warm temps approx every 120k years, and has been for at least 500,000 years, if not 1 million years or more (the sliding scale on the referenced graph is hard to discern). We're - in fact - overdue for our most recent pulse of warmth.
Now, hypothetically: cast us back to the last pulse, about 200k years ago. Had human society existed (in its current tech state) at that time, how would we have interpreted that pulse? Would we have recognized it as a regular cycle, or would politicians (and their fellow-travelers, who have been screaming about the destruction of the environment for 40 years now) have opportunistically re-interpreted it as "human-caused"?
-Styopa
Mars lost its atmosphere relatively quickly because it doesn't have a strong magnetic field to protect it from the solar wind. While earths atmosphere would expand somewhat as it warms, it would still be well within the protective confines of the earths magnetosphere. So, no, the earth will not lose its atmosphere with runaway global warming.
Seriously? Who'se worried about that? And based on what evidence? It has also been found that increased CO2 cools the upper extremities of the atmosphere causing it to "shrink", which is quite the opposite of bleeding off into space.
Benefits: We get great new places to live in northern Canada, Siberia, Greenland, etc
While making the tropics, where most of humanity lives, uninhabitable.
Billions of tons of food will be able to be grown where it never has been before
And billions of tons of food will be unable to be grown where it has been before.
Give me Classic Slashdot or give me death!
49 million years ago, CO2 levels were 2-5 times higher than they are today, methane concentrations were 2-3 times higher. 500 million years ago CO2 levels were 20 time higher. In neither case did run-away global warming occur that allowed "our atmosphere to bleed off" A "destroy the Earth's capacity to support life" scenario is not realistic by any stretch of the imagination. What we need to be worried about is the economic impact of shifting acricultural regions, rising sea levels and potentially more active weather. Mother Earth has been through catastrophies far beyond anything the human race can currently inflict. Life survived Chicxulub, Sudbury, and Vredefort, it survived the Oxygen Catastrophe. It will survive us, the question is, will "we" survive us
You are confusing localised weather and global climate. Your existence is dependent on the global climate - food prices, diseases, populations, infrastructure, foreign production, etc. etc. etc. all play a massive part in keeping you comfortable. It seems you don't understand the implications of global warming. It's not just that the sea will rise a bit and the summers will be nicer - it's far more serious than that. It is possible to do something about it - if you value your grandkids, that is. So be selfish and fuck future generations, or actually do something good and at least try to make a difference.
Your ignorance of this subject is simply staggering. I beg you, as one sentient human being to another - research the various effects on the global climate (of which this cycle is just one), and see the correlation (or lack thereof) to global temperature. It's not as clear-cut as you seem to think it is. Hint: If you think you can debunk a well-established branch of science in a one-paragraph post to Slashdot, you're most likely wrong.
Well, the article didn't note the alarming part of that so well. The issue isn't the temperature at the moment so much as the really alarming rate of change. Here's a chart that documents the history and recent changes. Notice anything odd about the recent record relative to the entire temperature record going back to the dawn of agriculture?
A number of reviewers have noted that the methodology is somewhat flawed in that the temporal resolution of the proxies used to reconstruct ancient temperatures is very low - up to 500 years, whereas the modern global temperature data that is appended to produce the hockeystick graph is at high resolution.
http://www.newscientist.com/article/dn23247-true-face-of-climates-hockey-stick-graph-revealed.html
This, along with the averaging effect of combining numerous noisy proxy data streams has the effect of removing significant features such as the medieval, roman, minoan warming periods where temperatures rose by as much as 2C for periods of 1-300 years. It also removes similar long duration temperature dips.
So ultimately the picture presented of historical temperatures is not realistic, if we were to apply the same temporal low pass filtering to the modern temperature record as well you would not even see the recent temperature rise, and the little ice age would probably disappear as well. Eg look as Gisp2 ice core temp data for a reasonably good picture of historic temperatures:
http://img695.imageshack.us/img695/6063/gisp2.jpg
shows same general trend as this paper, just preserves the frequent 1-500 year temp oscillations

Warming is good for life. You might not be acclimated to it but the reality is when we have periods of cooling we have die offs and when we have periods of warming there is an expansion of species, of biodiversity. The Earth has been much warmer in the past and that was good for life.
Well, clearly you have all the answers so let me ask you: how rapid can the warming occur in order for an "expansion of species, of biodiversity"? Because something that concerns me is that the larger species -- especially those we depend on for food -- have a hard time rapidly evolving within a few hundred years. Those high points of warming happened an order of magnitude or two slower than the rate we're moving at. The bacteria and cockroaches will flourish but the humans, plants and meat sources are going to have a really bad time. In this case, the rate of change or "derivative" is what should be concerning you.
Keep embracing accelerated global warming though. Let me know when the water wars near the equator and famines start to cause you concern.

One more con -
As the level of CO2 rises, your respiration rate goes up. Breathing faster than needful is hyperventilation which, even when minor, over time gives rise to more and wider spread stress-related illnesses. Some are systemic; some organs will complain more than the rest. I've forgotten all the particulars (haven't looked into it in a while) but all the info is readily found - except that there's been damn-all research on it. Takes a while for folks to wake up, I guess. I'm mindful of it because the relative atmospheric CO2 content has increased by about a third since I was a kid.
May be balanced by being the century of 'gene, nano, neuro, cyber' so we might be able to fix lots of body stuff.
I don't think you understand how agriculture works. If you cut hydrocarbon input, production collapses, and poor people everywhere starve. Compared to the possibility of a few degree temperature increase, that is far better for everyone involved.
Except that's not really the case. The grain belts of the world are all in temperate zones, which would only benefit from a slightly higher temperature. The lands that will be opened to farming are just as rich as our grain belts were before we started farming them.
There is precedent for the equatorial regions being uninhabitable in the history of the Earth, but that is a long, LONG way away, and we have geoengineering methods that could prevent the worst of that in any event. Or rather, we will in the future, if crazy people like you don't destroy our economy and send us back to the pre-industrial era.
I find that graph a little hard to read, given its scale and lack of other documentation. I would love to see the source data and study if it is publicly available. I am a bit curious about why the data stops at 1990 (I assume that is the year of the study). Also, how can we be sure about temperature data going back 13k years to within hundredths of a degree of precision? Is it fair to get alarmed over a 0.6 degree rise in average temperatures over a 30 year period, but then compare them to historical estimates which may not have the same level of detail? I am not trolling; just trying to understand what this is telling us.
I was being quietly facetious. Indeed at some point in the 110,000 year cycle, we are destined fairly soon to start moving into a down trend (55,000 years) and then people are going to scream bloody murder that "Cooling is the fault of industrialization's soot." or similar.
The Solar induced Ice Ages will return, in spite of politicians, do-gooders and worry warts. Northern hemisphere above about 50 degrees latitude will again go under a kilometers thick ice sheet. No one darn thing humans can do will stop this.
It's the poor who will pay. I don't mean the middle class, I mean the 1 billion+ people who live on less than $1 a day. They will starve in greater numbers and die in greater numbers - they can't move, or "buy less ski equipment". I get that you don't care about that, but I hope that as a society we can bring ourselves to give a shit.
While I completely agree with your sentiment and emotional judgment, I slightly disagree with the point you make here. If I as a member of society want to reach out to the world's impoverished, I'm not going to effectively demonstrate my altruism by buying a hybrid or pushing for 'better' emissions laws. I'm going to do it by spending some of my resources supporting my favorites of the many community organizations, charities, government organizations, individual efforts, etc. who are striving to implement long term solutions to the problems of impoverished nations.
Those living on $1 a day don't give a damn about my CO2 emissions. They'll be dead before that really bites them. They want food and shelter today. The upcoming generations suffering the same fate is an issue, but with little effort, we can fix many of the the root causes over the coming decades, and it has almost nothing to do with our emissions. We should be developing and executing plans at many levels to build up basic infrastructure and establish the rule of law, and we should be looking at areas with great need and areas where we have a great ability to bring about meaningful change. Hopefully then the great grandchildren of those people can eventually join ours in a world community trying to resolve more of the global warming mess. And if not, they can all compete to buy prime Canadian and Siberian coastal real estate. Either way, nobody is starving, and our world will be much better off than if we continue to sit together arguing about emissions and giving the impoverished our pity while we leave them alone to figure out their problems.
Today, I think one of the biggest battles is to change the views of the citizens of our developed societies. I hope by the end of my lifetime we've started to believe we have a great responsibility to uplift the impoverished fellow citizens of this planet we all share.
So you are saying that mankind actually went through the industrial revolution 2,750 years ago, and like, all the history textbooks are like, totally lying to us?
Groovy, man.
In case you don't get it, your hypothetical is poorly designed. It should be year one, year 2200, year 4400, year 6600, year 8800, and year 11000, of which humanity has been significantly industrialized for only 100 years.
Also, it's pretty twisty of you to try to claim that the authors of the study were so stupid as to take only a few time points, rather than a more continuous histogram. Twisty twisty snake, AC.

I think you're missing his point. The temperature and weather patterns on this planet are not constant, they're constantly changing and have done so as long as the planet existed. There's nothing you and I can do about it, and adding stupid taxes and fees only make things even harder for people to cope with the inevitable climate changes that would still come if we all still lived in caves and only ate dead leaves. Earth does not care about cities, crops, religion or living things that try to survive on it because it's just a ball of molten iron with a thin crust of rock and carbon. We live on it but some day we won't.
Time flies when you don't know what you're doing
Right, because weather is fucking totally the same thing as climate.
I got a statistic for you. You're a dick. Calling an opposing viewpoint "pro-ignorance" totally works.
So, in the top 25% is now "close to the all time peak" for the last 11000 years?
Would it be vaguely possible to at least get titles that weren't deliberately alarmist?

Please try to understand It' about the alarming rate at which it's happening.
" temperatures have been increasing at a dramatic clip: from the first decade of the twentieth century to now, global average temperatures rose from near their coldest point since the ice age to nearly their warmest"
So a temperature that took thousands of years rise previously took 100 years.
If we where at this temperature after a 6500 year upward trend, then you would have a point. but we are not, and you do not.

We put out more CO2 that can get back into the cycle.
Think about that.
And its not 'a few degrees' it's a constant temperature climb.
And don't act like we are talking about the complete removal of all CO2. You're being stupid.
The Kruger Dunning explains most post on
If I had to guess, it's probably a reaction to the ridiculous alarmist end-times rhetoric from the less competent believers.
This is why the US has done nothing about global warming. The actions of fetishist environmentalists are only tangential to the issue. You see, all you have to do is *claim* that radical environmentalists are doing yadayada, then have some liberal say something snarky, rinse and repeat ad-neuseum on Fox and conservative radio, and the oft-repeated lie becomes the truth. Just as Hitler claimed.
Every time an industry is up for regulation, they claim that the world is going to end. Think: acid rain (it will ruin the economy, and do nothing about acid rain anyway!!!), think: CFCs (it will ruin the economy, and do nothing about the ozone anyway!!!). This whining works, for decades and decades, because they buy laws and politicians, and lobby the public with all sorts of disinformation.
The largest segment of alarmists in the climate change "debate" are those that claim action will ruin the economy, when there is empirical evidence today that this is simply not the case.
And the GOP is apparently the party against crony capitalism.
Like all pain, suffering is a signal that something isn't right
Actually we are in the middle of an ice age. I think he means glacial and interglacial periods.
The Kruger Dunning explains most post on
Right, so we agree that things will change. And of course, human beings are incapable of dealing with change, and always have been. Remember when we died out during every one of those 74% of times that were cooler than now, and the 24% that were hotter?

Help stamp out iliturcy.
Don't you realize that it'll warm the Earth? In 10,000 years San Francisco Valley would become a bay, and we wouldn't be able to walk to the Farallon Hills any more. We'll have a helluva time getting back to Asia if we decide we don't like it here. It'll be the end of the world as we know it. A complete and utter disaster.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
The chart is the data from the paper which is the basis for this story. Previous temperature record reconstructions only went back 2,000 years or so, this one went back over 11,000 years to provide more context. Even in the shorter 2,000 year chart the recent change is hard to parse since it's so nearly vertical. Anyway, the paper here was to show how the recent changes are far, far, larger and more rapid than any that have been seen since civilization began.
This is just a silly wording of the usual argument from so-called conservatives that was earth was warmer 250 million years ago so there's nothing wrong if it rapidly warms today and "earth will recover anyway". This should be modded "+5 Troll".
Besides, why wouldn't "conservatives" want to conserve Earth's climate?
This is not correct.
The magnetic field is helpfull but not that relevant.
Mars atmosphere is mainly "frozen" and is captured in the rocks. If you warm up Mars to roughly 20Â at the equator it will have an atmosphere again with roughly half the pressure earth has at the equator.

If that happens then it's only a matter of time before our atmosphere bleeds off and the Earth is left looking a lot like Mars.
That is nonsense. Mars "lost" its atmosphere due to cooling, not heating.

You might as well say we can do nothing about Hitler, and the Earth is just a ball of molten iron so let's kill all the Jews, Earth doesn't care about them.
Benefits: We get great new places to live in northern Canada, Siberia, Greenland, etc.
If you like arctic winters, yes. Otherwise: no.
Even if it gets "warmer" in winter you still have polar night ... it is still dark and cold. So your benefit is rather overrated.

Singel human beings can ... well I would not call it change, but can do something to survive.
However nations? What happens to the USA if half the "country" is desert? Riots? Revolution? Sure, a few just move to better places, what about the rest of the 300 million population?
Many changes wont be slow, but abrupt. Five years ago an area was still comfortably farmable, the last 3 years there was a drought, but you still could harvest crops. And from next year on ... no rain for 10 years ... desert. Last year you still thought the drought will be over some time. Now you lost everything.

It's not about the change itself, but rather the rate of change. The closest things to the current rate of climate change are extinction events. Humans have a huge impact on how well the environment does. It's hardly a situation where our actions are irrelevant. Humans have created massive ecological disasters in the past, and it took a lot of government intervention to get people doing things correctly. Just read about the Dust Bowl. That was caused by the fertile soil lulling farmers into thinking they didn't need crop rotation. The US government actually had to pay the farmers to get them to use proper farming techniques, as they all wanted maximum short term production.
Considering that only half of france surrendered ... and that the south surrendered to the north, does that not make americans "surrender monkeys", too?

....(and I haven't examined the various data sources to make a judgement on that yet) but thank goodness! This means that we've finally recovered from the effects of the last Ice Age!
Of course, it also means we're going to start the downhill slope back into the next one if historical records are any indication....

Of course humans won't survive on this Earth without a lot of other living things that we depend on surviving too. Are we going to fix all of them too?
Actually temperatures have been on a downward trend since about 8,000 years ago until the recent sharp rise that happens to coincide with the rise in human burning of fossil fuels. According to a study a couple of years ago we've already caused enough temperature rise to prevent the next glaciation from happening.
Weather models are not climate models. They are two fundamentally different problems. Since climatology is fundamentally a statistical science modeling climate is like modeling the outcome of 1,000 rolls of a pair of dice.
Sez the guy who has no clue about the actual science behind the study.
Except the simple assumption that it's been warming since the end of the last glaciation is wrong. Temperatures hit a peak about 8,000 years ago during the Holocene Climatic Optimum and have generally been cooling ever since.
The opportunity for "wrong" is that you can be biased to choose one expert or priest over another. You're likely to make this choice based on, to some extent, what the guy next to you thinks.
I choose the concesus. I never choose "one" expert unless I'm sure that expert is representing the concensus opinion of many scientists. If there's large segments with varying opinions, usually indicating a lack of data to explain which is more correct, then I remain agnostic. If there's one expert who disagrees with everyone else, I am leery of that expert's opinion, even if it's exactly what I want to hear.
If that expert turns out to be right, then that will eventually be reflected by the rest of the scientific community as the evidence becomes more and more convincing. As has happened over and over again.
Could this still mean I pick the wrong group of experts? Yeah.
Is that anything like a priesthood? No. That comparison is just stupid.

If the temperature of the earth were higher, it's atmosphere would be a lot thicker too, but that's not the point. Mars cannot hold onto an atmosphere long term because it doesn't have anything to keep it from being blown away. Even if we crashed a bunch of comets into it and increased the temperature by adding greenhouse gasses, the atmosphere would still eventually be blown away by the solar wind.
It is also possible to operate without beryllium fluoride in the salt. It is possible to operate on lithium fluoride-thorium fluoride eutectic without beryllium, as the French LFTR design, the "TMSR", has chosen. Also as far as Zirconium, LFTR's create Zirconium during their burning process as a byproduct. Fission of 1000 kg U-233 produces several chemicals essential for industry, readily extracted from a LFTR, including 150kg xenon, 125kg neodymium (high-strength magnets), 20kg medical molybdenum-99, 20kg radiostrontium, zirconium, rhodium, ruthenium, and palladium. Don't take my word for it. There is NO shortage of natural resources. Sufficient other natural resources such as beryllium, lithium, nickel and molybdenum are available to build thousands of LFTRs. see Wikipedia. http://rawcell.com
It's not that type of reactor, as the second item in a google search for "LFTR reactor India" would have told you.

As I wrote above, it's a few decades more advanced than the 1950s oak ridge devils brew you are going on about.
Also, sadly, the reactor you are referring to in your article is neither LFTR or even a thorium reactor at all - the reactor nearing completion at Kalpakkam has a wikipedia page.:
http://en.wikipedia.org/wiki/Prototype_Fast_Breeder_Reactor
It's worth writing about on it's own merits instead of pretending it has anything at all to do with LFTR.
I did not mean to ask for the raw data, although I see how it could appear that is what I was looking for. The graph appears to have been pulled from a published paper. A Google Scholar search did not reveal the source of the graph. A link, or reference to the paper would be helpful.
Good question. Consider that we're living in the largest experiment ever performed by humans. Enjoy the ride.
Aided and abetted by humans, we've already been losing several hundred species per day (rough estimate, varies by source). Who knows what's lost with them - a novel bit of chemistry or adaptation, some substance/protein/whatever made by them that might be useful to us? It'll only increase, yet other species will adapt. We already see migration, changes in reproductive cycles, for example. As for us, I figure it's open-ended. "We don't know what we don't know" and "wait and see" are great comfort, no?
You are right about this being a very large experiment with no guarantees as to what the outcome will be.
I'm not that concerned that humans will survive. After all we've managed to make a life in places as diverse as the Kalahari Desert and the high Arctic. As long as some of us can find food and shelter the species will survive. Other species are adapting, the question is can they adapt fast enough to survive. We'll find out.

Sure, and Mars has been around for billions. Some of it's atmosphere may have frozen, but vastly more has been blown away.
Did you do the math?
With all due respect I doubt that.
The "blown away" thing is a myth from science fiction stories.
