Global Warming Debunker Debunked
Earlier this month we ran an article linking Christopher Monckton's attempt to discredit global warming. The submitter asked plaintively, "Can anyone out there go through this piece and tell me why it might be wrong?" George Monbiot has now done so. From the article: "This is a dazzling debunking of climate change science. It is also wildly wrong... In keeping with most of the articles about climate change in [the Sunday Telegraph], it is a mixture of cherry-picking, downright misrepresentation, and pseudo-scientific gibberish. But it has the virtue of being incomprehensible to anyone who is not an atmospheric physicist... As for James Hansen, he did not tell the US Congress that temperatures would rise by 0.3C by the end of the past century. He presented three possible scenarios to the US Senate — high, medium, and low. Both the high and low scenarios, he explained, were unlikely to materialise. The middle one was 'the most plausible.' As it happens, the middle scenario was almost exactly right. He did not claim, under any scenario, that sea levels would rise by several feet by 2000." And on the political front, the only major ally for Pres. Bush's stand on global warming, Australia's Prime Minister John Howard, is now willing to look at carbon trading.
It's amazing how many monikers this "debunker uses". "cock-a-hoop", "cherry-picking, downright misrepresentation and pseudo-scientific gibberish." And while the original article mentioned sources and showed the numbers he was talking about, this article just keeps saying how the first was incorrect, and how others have proven this or disproven that. However, the details are not found there.
This is just pandering to those who want thim to respond. But there's really nothing to see here if you don't like name calling.
Have you read my journal today?
Can we make a hole in the ozone so some of that CO2 can leak out and make everything right again?
There's higher pressure in a warm beer because the product of pressure and volume increases with temperature. Carbon dioxide doesn't magically leak into the beer as it gets warmer. You're not an atmospheric scientist, don't try to act like one on slashdot.

If you'd like to run a global climate model (GCM) yourself, you can now do so. The NASA GISS Model II GCM has been ported to run on Mac/Win computers and wrapped in a point-and-click interface. GISS, the Goddard Institute of Space Studies, is the lab that Hansen (mentioned in the summary) runs.
The EdGCM project provides this free GCM wrapped in a GUI. If you want to add CO2 or turn down the sun or whatever, you may now do so with some checkboxes and sliders.

The earth *IS* getting warmer. This is a fact. Annual temperatures are hotter than they have ever been since we started keeping records, glaciers are drastically smaller than they've ever been in recorded history, and the polar ice caps are shrinking. The earth _IS_ getting warmer, ergo, global warming is real.
What is causing it, however, is another matter... some say there is proof that humans are causing it, others will say it's merely circumstantial... that this warming is just part of a natural cycle the earth goes through before another ice age and then a gradual reheating (the latter period being one in which we are currently living).

The Debunker who debunked the debunker has been debunked.
I really think almost all of these questions end up as what I call side of the room questions. People line up via their political orientation, and they end up on the side of the room with Michael Moore and Al Gore, or Rush Limbaugh and Ann Coulter. You might not like everything about the people on your side of the room, but if you find the other side of the room more unpalatable, you shut up and live with your reservations. The polarized nature of politics makes you at least act as if you buy into everything from your side of the room--if you vacillate (waffle!) you might embolden the other side of the room. Aaargh! So smart people end up believing stupid stuff, just so they don't have to stand on the same side of the room as Michael Moore (or Anne Coulter, depending on your aversion). And no, I'm not exempting myself from this. I find Michael Moore's stuff smarmy and irritating, but I'd do some serious soul-searching if I ended up on the same side of the room as Anne Coulter.
By your own statistics, we will double the amount of CO2 in the atmosphere in less than 100 years. That is not a negligible point.
CO2 provides the most climate forcing due to its chemical properties and relative bulk in the atmosphere. To forestall the atmospheric H2O canard - H2O is a more powerful GHG, but it only maintains the current temperature. It is not a forcing agent because it cycles too fast. H2O cycles in 14 days. CO2 cycles in ~150 years.
The comment about rain scrubbing is utterly nonsensical. It shows no time component and is irrelevant because rain doesn't fall evenly over every square meter of the planet.

"I recognise the surface of the earth is warmer and that an increase in greenhouse gases caused by humans is contributing to the problem," he said during a visit to Denmark en route to Gleneagles.

>Effect, not cause.
Both. One of the reasons we need computer models. Especially since warmer climates speed up some processes that *absorb* CO2 as well as speeding up processes that release CO2.
CO2's causal role is simple phsyics. The numbers on feedback have been hard to pin down. But there's not any question that *other things being equal* more CO2 means a warmer planet on average.
>Humans are unlikely to be the cause:
We are, indeed, responsible for only a small percentage of the CO2 in the atmosphere. The amount that was there before we started is responsible for keeping the oceans from freezing. A small change to that large an effect is worth thinking about.
I've been following global warming for a long time now doing a lot research on the side for the last couple of years. Here are some facts about global warming. Some of which you hear and don't hear from the main stream media: 1.) The world appears to be getting warmer with many computer models showing an increase in global temperature. 2.) Tying a trend to warmer temperatures based on older data from the early 1900's is suspect at best. Good, reliable, accurate scientific equipment that measures the temperature wasn't readily available until recently (late 1900's). 3.) Apparently, the Earth magnetic field has decreased by 10% in the last 150 years (source: http://www.space.com/scienceastronomy/earth_magnet ic_031212.html). I'm an electrical engineer and during my studies in particle physics, I learned that a particles velocity can be affected by magnetic fields. I keep hearing about the increased activity of our Sun and believe it's possible that more of the Sun's radiation is penetrating the Earth's magnetic field due to it being weaker. If more radiation hits the Earth and the Sun is spewing out more heat, shouldn't that also increase the overall temperature of the Earth and can global warming be attributed to this?
4.) Jupitor is experiencing the same climate change that Earth is. (source: http://www.space.com/scienceastronomy/060504_red_j r.html [space.com])
5.) Mars is experiencing the same climate change that Earth is. (source: http://www.space.com/scienceastronomy/solarsystem/ mars_snow_011206-1.html and http://www.dailymail.co.uk/pages/live/articles/new s/news.html?in_article_id=410901&in_page_id=1770)
How can you explain the recent same climate changes on different planets? I doubt it's all those cars being driven there.
Is it possible that the warmer temperatures that Earth is experiencing are caused by cyclical natural phenomena? What about glaciers in Greenland that have been shrinking for 100 years (source: http://www.breitbart.com/news/2006/08/21/060821191 826.o0mynclv.html [breitbart.com])? Also, how do you explain huge ice ages on Earth? Were thse caused by huge carbon emissions or was it a small natural climate cycle that just happens? Were those climate changes, which are no doubt more extreme than what's going on now, caused by the combustion engine?
A 22.5% increase over 2 centuries, 19.4% in 45 years, is a small percentage?

factors.

Well, I suppose it depends on what you mean by "consensus". Certainly not all qualified scientists believe "human caused global warming" is a dominant factor in current climate change. You might check this 2002 article (for instance):
http://www.newsmax.com/archives/articles/2002/5/14 /161152.shtml
The one tangible thing that's been done to try and address global warming is the Kyoto Protocol. It is quite flawed, though, in that it gives exemptions to the countries which are most likely to be big polluters in coming decades. It would also impose economic penalties on countries like the US which are already doing quite a lot to reduce their environmental impact.
If /.ers want to rally around a single approach that would be beneficial not just to human related global warming if it exists, but also to energy independence and reduced pollution, do whatever you can to advocate constructing new nuclear reactors here in the US. That is the single best thing we could do at this point.
Those who can plug in hybrids or electric cars to charge would then be running nuclear powered vehicles...sweet! :-)

Well, there's what Hansen said, and there's what got reported. The meta-debunker went back to primary sources and found:
Gee, that's a lot of broken links.
Ok, so I'll have to repeat my standard response to stuff like this.
I love this logic:
1. The climate has always been variable.
1a. The climate is variable on other planets.
2. Therefore, man is not having an impact on today's climate!
QED, right?
Here's an exercise: Explain to me how increased levels of CO2 (which are rising due to humans- I challenge you to find an alternative explanation that has not been debunked from here to Shanghai and back), which Arrhenius demonstrated over 100 years ago [nasa.gov] could cause climate change, can't possibly be causing climate change?
Hey, climate science is uncertain, and questioning the current consensus is great. But if you are going to do so, please find a coherent argument why the current thinking is incorrect (again, please stick to the stuff that hasn't been shown to be wrong 100x over). So please go read RealClimate, debunk them (you have to do better than the M&M side show), and then we can have a conversation.

To be fair, part of the reason for his behaviour is a long standing medical problem. I wouldn't mention this if it were not for the fact that Wikipedia has seen fit to publish it.
Global warming is a myth. Just like those dinosaur bones.
I would like to see a climate study done by someone who doesn't have an agenda.
It seems like everyone I see starts with the premise that Global Warming is reaching epic proportions or that it is bullshit. It doesn't seem like anyone is going out there from a neutral point of view.
It seems like anyone can spin data to prove a point they already have in mind.
Newsflash: Methodology is EVERYTHING in science. If your methodology is bad, your data is less than bad - it is misleading. Hence why so much revolves around whether people followed proper methodology when presenting their data.
The reason that the "save the rainforests" is quieter now is because people are actually doing something about it.
Finally, this entire "you have to present both sides of a story" has to stop. Now. This is not a game show where you get to choose which door to open. There is a public debate on an important topic, and that debate needs to happen in public. That's true. However, debating something in public does not mean that you simply pick a side you like and then clamor that everyone needs to listen to you "because all sides need to be heard". It means debating the theory, the data, the methodology, investigating problems and striving towards finding the most reasonable answer or theory. Granted, most news stories don't get this either, but that doesn't mean that we can't tell them to stop being idiots about the way they present science debates.
Those who can, do. Those who can't, sue.
From the Arrhenius link which you provided:
.005 degree rise? If the latter, do we really need to be worried about it?
As Arrhenius predicted, both carbon dioxide levels and temperatures increased from 1900-1999. However, carbon dioxide in the atmosphere has increased much more quickly than he expected, but the Earth hasn't warmed as much as he thought it would. (Graphs by Robert Simmon, based on data from NOAA and the Goddard Institute for Space Studies)
You'll be hard pressed to find anyone who believes that carbon emissions have no effect at all on the global temperature. What's in debate is just how much effect they have. Will a tripling in global carbon emissions cause a 5 degree rise, or only a
That's the kind of questions which lead to questioning of the overall global warming theory, because they've never been successfully answered. And that's why questions about climate change on Mars and Venus become relevant - because if the temperature is changing on those planets then it's quite possible that carbon dioxide is an almost insignificant factor in the temperature rise which OUR planet is experiencing, and that the major cause is the sun.
Hell, for all we know, the rise in CO2 might be the symptom instead of the cause of global warming. Granted, it's unlikely, but how do we know for sure? Has anyone measured CO2 levels on mars and venus? So far the only proof we have that co2 is linked to global warming is that any time in the past when temperatures have gone up, so has CO2. How can we prove which one is the cause, and which one a symptom? And if we can't even prove that, how in the world can we possibly expect to determine exactly how much effect CO2 has on temperature?
The real problem with many of these articles 'debunking' global warming is that they have no real intent to disprove the science behind global warming, rather they have the goal of creating confusion and the appearance of controversy with a net result of inaction and a continuation of the status quo. This is why virtually all 'debunking' publications occur in the mainstream media whereas the actual science continues where it always has, in academia, away from the public eye.
One can only speculate on the motives of these 'debunkers'. Obviously there are those who profit mightily and so have a powerful interest in the status quo. Next, there are skeptics who will never accept anything, no matter the evidence or risk of inaction. As near as I can tell, their only goal is to drag as many people as possible to their side. Finally, as an Albertan, I see many other people who have been frightened by the economic doom and gloom emanating from certain quarters. These people will not accept Climate change because they see it as an attack on them and their livelihood. They don't want to change how they live so they choose only to believe what will enable them to continue as they are. The first two groups of people can never be convinced so we shouldn't really bother trying, rather we must be mindful of their effects on legitimate debate. The third, and far largest group, can be convinced once they realize that combating climate change is not just a problem but can be an opportunity; an opportunity to reinvent society and unleash innovation! Certainly, once you accept the science behind climate change most rational people must acknowledge a moral imperative to our fellow human beings to combat this issue.
I can't, but I'm sure the Republicans are behind it.
"The Federal Reserve is a fraudulent system."--Lew Rockwell
End The FED. -
1) Yep.. lots of scientific consesnsus on that.
2) If you are talking about human recorded temprature mesurements from those periods then we agree. And so scientists generally try and use non-human recordings, such as effects on tree rings, the growth of coral (very temprature dependant, and in the middle of a huge heat sink), etc... So there is a lot of data that can be distilled into good records.
3) If you took engineering then you should know about the laws of thermodynamics, and thus know that you are mearly playing with where the energy is absorbed or reflected, not changing those ratios. You should also know that most of the suns energy output that is absorbed by the earth is not in particales that are affected in any real way by magnetic fields.
4) Your source does not say that Jupiter as a whole is warming up... only that certain spots seem to be. There is a huge difference in those two statements.
5) We don't know enough about Mar's climate to be able to take any lessons out of it. In fact your article states this repeatedly.
6) The answers to many of the rest of your questions are avalible from a lot of sites. A lot of them do examin cyclical effects, and look for the causes. But the very people who are doing those studies and are the best informed about these things are the ones who are very loudly sounding the alarm.
The better question is why do people keep listening more intently to politicions and businessmen who have a vested interest in the status quo, as opposed to the scientists who have dedicated their lives to studying these things and have no vested interests (or at least not as big an interest).
Throughout history, CO2 levels have always lagged behind temperature increases. Even RealClimate admits it http://www.realclimate.org/index.php?p=13.
A major component of this is that climbing temperatures release large amounts of CO2 locked in the permafrosts. http://www.usatoday.com/tech/science/discoveries/
So there, in two links, are strong evidence that CO2 change could be a result of temperature change and not vice-versa.
Now I await the flames... let me guess the order:
Like I said, I've done this before.
Life, the Universe, and Everything... in my image.
Even more importantly, rain only falls in the lowest parts of the atmosphere. Anything above 40,000 feet won't ever see a drop of rain until it falls to lower altitudes. So expecting rain to clean the entire atmosphere is, at best, a slow process.

John Howard is a very accomplished politician. He's making "climate change" noises now purely to distance himself from the US election results. This is the man who claimed that the Boat People refugees were "throwing their children overboard" even though the military told his people that wasn't true within 24 hours after the alleged event. He continued to support the Children Overboard story for over a month, until after the Federal Election. See http://www.alp.org.au/features/lies.php for a breakdown of some of his side-stepping and double dealing. Or even better try http://www.google.com.au/search?q=john+howard+lies for a wider view.
John Howard has been using his absolute majority in both Houses to force all sorts of ideologically motivated laws through, regardless of how they may change Australian Culture. He seems to be intent on making us a new state of the USA. He is the person responsible for ensuring that the USA is not alone in its' Kyoto stance. He is responsible for a "Free Trade" agreement which is dismantling our fair-use provisions under copyright, is introducing DMCA legislation, is changing our patents office to be in line with the US model, is diluting our PBS (the Government sponsored sale of pharmaceuticals, all of which must happen before 2010, yet the USA is under no obligations under this agreement until 2022.
He is responsible for setting up concentration camps for refugees (more precisely, for illegal immigrants who are requesting refugee status). Most of these camps are in the back of beyond. There are children who have liven for most of their lives behind the razor wire, and there is a horrific incidence of mental illness associated with this detention in sub-human conditions.
Now that public opinion can be shown to be swinging against the US Republican approach to the Middle East and "The War on Terror" he's simply waving an extremely large, colourful and exciting flag (climate change acceptance) to distract people from his complete failure to interface with the Democrats. The news is now that the Democrats are going to demand a US inquiry into the AWB scandal (The AWB, run by Howard's mates, was busted paying hundreds of millions of dollars to Saddam Hussein to get around the trade sanctions, abusing the UN "Oil for Food" program).
I, along with many other informed Australians, do not believe there is any change of heart in Howard's new "Climate friendly" position. It's all just an attempt at distraction from the real issues.
Most of what you say is true. Up to the "and not vice-versa" part. Bzzzt! Faulty logic! The first part of your statement is true (CO2 can lag temperature changes), but you present nothing to prove the vice-versa (CO2 can't be a driver) part.
Sure, in the past CO2 has lagged temperature. However, that doesn't mean that it hasn't sustained climate changes as a positive feedback. What it does mean is that CO2 has often not been the driver for climate change events. Until now.
We are generating lots of CO2. A small amount relative to natural fluxes, but enough to . Can anyone provide a plausible alternative hypothesis for current conditions?
CO2 acts as a greenhouse gas. This is basic physics. What's not so basic are all of the other feedbacks, positive and negative- water vapor, ice cover, and so forth. That's where the action is. Let's talk about that. But to get caught up talking about whether we are responsible for increases in CO2, and whether or not CO2 is a greenhouse gas, is just a colossal waste of time. It's basic frickin physics and chemistry. It's the fluid dynamics that makes everything so hard to resolve.
To recap:
Climate varies naturally. That doesn't mean it can't be affected unnaturally.
Historically, CO2 concentrations have lagged temperature changes (b/c yes, Virginia, there are other factors that affect climate). That does not disprove that you can drive climate change with CO2; it just hasn't been tried often.
All else equal, higher CO2 = higher temperatures. Basic physics. The problem is the all else equal part.
Humans are trying an interesting experiment. What happens if we try to force climate change with CO2?
Why does everyone here think that they are smarter than climate scientists?

Well, unfortunately these questions won't be answered any time soon with any degree of reliability, but rest assured that if they are I'll be coming around to collect that house, bike, car, etc :) You can keep the wife and kids though, I'm not in a hurry to acquire any of those.
Anyway, the way I see it, as long as we can't determine how much effect CO2 has on the earth, we can't effectively combat it. I mean, realistically, if we believed the global warming studies, we should be switching entirely to nuclear power within the next decade, and then bombing the shit out of any country that refuses to do the same. If the global warming proponents are right, the growing economies of India and China are a massive threat to the survival of our whole species. We either get them to stop polluting within the next 10 years, or we have to kill them off in order to preserve as much of our species as possible.
On the other hand, I'd rather not be an alarmist. I'd rather not ruin our economies, turn global politics upside down, and start multiple wars on the idea that maybe, just maybe, CO2 might cause the world to overheat. We can't be certain just how much CO2 affects global temperatures....but we CAN be certain that the Kyoto protocol is useless at combating it...and we CAN be certain that the only truly effective ways to combat CO2 pollution would also cause massive global economic disruption, as well as requiring force to implement. So let's do a little more research first, huh?
And now onto policy. Uncertainty yields inaction. That's quite a gamble. What happens if you wait too long?
That's a nice strawman, that we have to go to war to reduce CO2 emissions. It's especially funny that you talk about turning 'global politics upside down', like the status quo hasn't had any of that (see: Middle East oil). The cost of (low carbon) energy independence, fully accounted, might not be so high.
I agree that China and India are huge factors in the CO2 game. Especially considering their economic growth and coal reserves. Kyoto doesn't cut it. Agreed. One interesting issue here is fairness. In the U.S. we've generated a lot of wealth by burning fossil fuels; hardly seems fair to make the rest of the world cap their emissions at a fraction of our per capita emissions. But that's a challenge, not a deal-killer.
I would submit that we can address our CO2 problems without "massive global economic disruption," but that's another debate for another time. I need to ride my bike home and play with my kids.

Yea, someone else noticed that. And went straight to -1 same as my post will go. You can't rationally discuss religious issues with fanatics and most of slashdot fits that description when it comes to socialism and it's pet front causes.
Good grief, Slashdot thinks (from the way the posted it it is clear the editor is advancing this drivel as an "answer" to the earlier article) an op-ed in the freaking Guardian! by a socialist mouthpiece who thinks writing a book makes him an expert.
Ok, other than hearing the name pop up in moonbat circles on a regular basis all I know about the guy I just pulled from Wikipedia. But it is generally held to be a leftist dominated site so it is probably being biased for him and not against. Other than what looks like a politically motivated "environmental science" gig his other formal education is all fuzzy/political/socialist stuff except a degree in Zoology. And he is criticizing his opponent for not being an expert. Pot, meet kettle.
This only reenforces the asstertion I made in the thread for the original piece that in the end all us laymen can do is evaluate the credibility of the proponents for each side. On the pro GW side we have an assortment of socialists and marxists who, coincidence of course, are preaching that if we don't all adopt a one world socialist government that will be powerful enough to save us from Global Warming that we are all going to die. Meanwhile the GW believer who also belives in individual liberty and Repreventetive governments is all but unheard of.
Now combine with the fact that all the leading lights in the political face of GW have been WRONG on every other major issue they have championed and it gets hard to buy into it. You name the failed idea, they pushed it. Appeasement of the Soviets, Nuke Freeze, Alar scare, Fat nazis, hell a lot of em were on board the Ice Age scare of the seventies. Then you get the ones who fell for Paul Erlich's doomsday scenarios like the population bomb who are now sure GW is going to kill us all... unless we abandon free markets and liberty.
Plus we get what looks like blatent supression of alternate theories and contrary evidence on these political science theories. Somewhat related example: I was watching Nove recently, the ep about the impending magnetic pole reversal. They showed a map of localized distortions in the field. Guess where the biggest one is? Right about where the Ozone Hole is. Now a weak spot would allow more radiation in and radiation breaks up ozone. Plausable enough that even if there is a hole in that reasoning they should have anticipated it and added a few seconds to deal with it. Silence, nary a word. Considering the political bent of the show it tells me there is probably something being covered up.
But back to GW. Solar output is up, temp increases are being observed on planets other than the Earth. No computer model to date have made an accurate PREDICTION of future longterm patterns. Managing, with enough massaging, to roughly reproduce past datasets isn't good enough to justify the sort of upheavals in society the GW faithful are proposing. We haven't had powerful computers long enough, period. Do a run today that predicts the weather patterns twenty years from now and in twenty years I'll consider the theory... IF it gets it right.
Right now we have two theories. The earth is warming slightly along with the rest of the solar system, perhaps with some influence from us but it has both warmed and cooled in the past and will almost certainly continue to do both in the future. The other says it is all our fault and will spiral out of control unless we act NOW and only socialism can save us. Occam's razor makes short work of this decision.

This is the "perfect is the enemy of good" argument. If we can't solve the entire problem then we should take no action at all. Not even a little.
It's a dumb argument. Saying that you don't know the exact degree of risk and beause you can't quantify it to nth degree of certainty you will do absolutely nothing is just insane.
"nd we CAN be certain that the only truly effective ways to combat CO2 pollution would also cause massive global economic disruption, as well as requiring force to implement. So let's do a little more research first, huh?"
Bullshit on all accounts. Oh and by the way I think a little more research has been done. It's just that you refuse to believe it. I don't think more research is going to change your mind. Lucky for us not even bush is that stupid. Even he is starting to come around.
evil is as evil does
The original article asked for a point by point analysis and evidence that the first article was wrong. This "believer" in global warming throws out a few personal attacks against the original author, and then boldly states that "The medieval warm period is accepted as having not happened" But gives no evidence whatsoever. I was taught about this period all through elementary school (in the early 80's). The leading theory then was it was this warm period that allowed the world to escape the dark ages because less people had to spend 100% of their time subsistence farming.
.1C? or even .3C?
Basically this article says "Global warming is happening, accept it" while providing no evidence other than "This guy's an idiot, he doesn't even have a degree". He only tries (very weakly) to debunk one of his claims, that the world has been warmer in the past. A claim which if not confirmed by the warm period of 5-600 years ago, is certainly confirmed in the earth's history. I read an article in Scientific American or National Geographic just last month that conceded this point, stating that the fluctuation of the earth's temperature has a range of 15-20C over the past 3-5 million years. Obviously more than 5 9s of that data is pre-industrial revolution (thus not caused by man). Those articles also plainly laid out that we are at historical lows in both temperature and CO2 concentration in the atmosphere.
If this Stefan-Boltzmann equation is designed to model a "black body" how is the UN justifying any modification to this model? What are they basing their alterations on? How do they decide how "non-black" the earth is.
The only other thing he mentions is Hansen's predictions. Ok, so Hansen had 3 predictions low, middle, high and said it would probably be middle, and it was close to that (.1C). The UN itself had much higher predictions (3C-5C) so why are we supposed to believe the UN now when they say 5C-9C over the next 100 years if its going to be closer to
In short, this is a completely typical article to see from global warming believers. They pretty much all go like this "The world is over, if we don't turn off all electrical devices by tomorrow and start riding bikes then global warming will kill us all. If you don't believe this statement you are an idiot!". If you ask global warming advocates for evidence they say things like "The evidence is all around you! Look at the hurricanes! Look how many people died in the heat wave last year!" People die in heat waves every year, the temperature and localized weather events fluctuate wildly. The climate on the whole remains pretty steady, and if anything activity on the Sun is much more likely to change the climate than anything we do.
