Climate Change Doubles Drought Stricken Area
Cally writes "The National Atmospheric Research Center has published research showing that the percentage of Earth's land area stricken by serious drought more than doubled from the 1970s to the early 2000s, and attributing this to global climate change. Interestingly, the lead author comments that 'droughts and floods are extreme climate events that are likely to change more rapidly than the average climate'."
It ins't a drought, it is just because everybody is drinking all the water up!

But it's a dry heat.
if there was global warming, then i think i wouldnt see snow in the middle of April while living in New Jersey. But i did...

Or at least the development, farming, clear cutting in those areas has caused it. Places where they measure temperature and rainfall the most are areas that are developed the most. The real question here is are these really long term changes or just natural fluctuations. 5, 30, 100 years are not long term in the scheme of things here.

I don't know about most places but my part of West Texas went from 9 inches or rain in 2003, to more that 53 inches of rain in 2004. Thats the most rain that my county has seen since it was settled in the early 1900's.

While he obviously meant it to mean that Earth is somehow delicately balanced and any movement in one direction or another will topple the climate for the worse, the fact of the matter is that the Earth has a natural environmental cycle that balances itself out over time.
So thousands of years ago there was an ice age followed by the long warm age we live in now. Before that there were other ice ages and warm ages. We put sulfur into the atmosphere, it comes down as acid rain, but somewhere else the sky is blue and the birds are singing. Just because we "damage" one area does not mean that we cannot improve another area.
Even in the case of climate warming, an increase in warmth leads to higher oceanic evaporation which leads to more cloud cover which counteracts the heating caused by the Sun (which is far greater a heat source than our piddly output) which then leads to global cooling again which leads to less oceanic evaporation which leads to less cloud cover which leads to
There is a problem with polluting because it makes our environment unlivable, much live a fish tank can't support aquatic life if there isn't a certain amount of care put towards keeping it clean.

I know it was meant in a serious manner don't knwo what's funny about it ? Really quite a sad story...
The term global warming was coined to describe the phenomenon of the entire weather system heating up, not the lack of snow in New Jersey. When the atmosphere heats up, it has more energy. That means increased activity, such as droughts, hurricanes and yes, snowstorms.
Also, there has been a good bit of discussion that it's possible that the melting of the ice on the polar ice caps is diluting the salt of the oceans, causing the Gulf Stream to change course. That would have the effect of reducing the temperature in the Northeastern United States and Great Brittan. It might just get colder!

It looks like the world's climate has changed a lot. When I was a kid, the winter started around Dec 20th and lasted until late March where I live. Nowadays, in the last few years, if we had any snow it was in November, with nothing during the time when the winter was supposed to be, with perhaps another strike of snow around April. Such "two springs" years became nearly a rule lately -- with a screwed up effect on the vegetation.
:p
Ah, I'm just 26, so that "when I was a kid" is not that far ago. Such a rapid, severe change of climate is something not to be trifled with.
But hey... we have several processes that cause rapid global warming running simultaneously with processes that cause global cooling. Things just have to act weird
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
It is almost certain that we change our environmet - but we have no idea how. We do one thing here, one thing there. Overall not much changes, but locally we strip the trees off a mountain and fuck up the climate. Armed with this singlar evidence we try and reduce 3% of 0.037% by 10% and then blame an earthquake tsunami on the fact that we didn't sign off on the 10%. We cannot model this shit, which wouldn't be a problem, except we don't have the humility to admit it. That's OK though. We can by a Prius. How much energy does it cost to make one of those. Your Dodge Charger probably does less damage.

Aliens!).
The Earth has gone through quite a few ice ages and then reversals -- right now I believe we're in the reversion from a mini ice age. While humans do have a lot of impact on our planet, it is remarkable how we think that the Earth is a static const, when in reality it's a volatile dynamic variable.
Increased temperature causes increased evaporation from the soil. So the soil is, on average, drier.

I was supprised that this article doesn't mention the effect of land use over climate change. One of the fastest ways the increase the local tempeture of an area is to cut down all the trees (raise by 2-3 degrees C). Remember over=grazing of the mid west led to the dust bowl during the great depression. Sadly a lot of developing nations use bad farming practaces, and that is why deserts are the only ecosystems still expanding today.
When it rarely gets too hot in my apartment I change the climate by turning on the air conditioning because it makes the climate more suitable for me.
I don't see why humans shouldn't seek to make the global climate better for us. If moving to resist global warming (whether 'natural' or not) helps us make the world a better place for sustaining our life then it sounds like a reasonable idea on the face of it.
Saying "it's been happening from the dawn of time" is stupid. So have tsunamis. So has disease. It remains sensible for us human beings to avoid contact with them where we can. Global warming may not be rushing upon us with such speed as the recent Asian disaster but if it, natural or not, is going to cause us damage it is only sensible to try and minimise that damage.

I clearly don't understand the problem here, global warming are caused by a fenomen called the greenhouse effect. To put it in simple terms, it make the atmosphere absorb more heat (that in the area above your clouds) thus increasing the temperature on the planet. And since water vapor (H2O) causes about 60% of Earth's naturally-occurring greenhouse effect, making higher oceanic evaporation a really bad thing.
Try getting some real facts, start with reading up on the greenhouse effect. Not hard to understand. One source are http://en.wikipedia.org/wiki/Greenhouse_effect but try some others too. Like go to a library and open a real encyclopedia.
All this would never have happened if big oil companies hadn't hijacked the green movement and prevented the widespread adoption of nuclear power, an energy source which doesn't release significant amounts of greenhouse gases.

From TFA:
"To see how soil moisture has evolved over the last few decades, Dai and colleagues produced a unique global-scale analysis using the Palmer index, which for decades has been the most widely used yardstick of U.S. drought. The index is a measure of near-surface moisture conditions and is correlated with soil moisture content.
Since the Palmer index is not routinely calculated in most of the world, Dai and colleagues used long-term records of temperature and precipitation from a variety of sources to derive the index for the period 1870-2002. "
So, not having a uniform scale, the researchers calculated the Palmer Scale values for the rest of the world using proxy data. But...
"Though most of the Northern Hemisphere has shown a drying in recent decades, the United States has bucked that trend, becoming wetter overall during the last 50 years..."
So the area whose data was not subject to extra data processing showed the opposite of what the rest of the data showed. At first glance, I'd say that they need to look at their proxy data. I know there is more to it (some other areas showed a wetter trend) and the article doesn't mention whether the US data was run through the proxy model, but it still seems suspect on its face.
As for "consistent with those from a historical simulation of global land surface conditions, produced by a comprehensive computer model", one wonders if the same assumptions that went into the reaserchers proxy data were also used in the computer model.

I sound a bit like Tom Daschel with this line but things aren't always Democrat or Replublican. Just because someone believes in god a certian way doesn't mean that they plot the increase in drought effected land. Oh, wait you didn't say that, you were completly off topic spouting shit, just like I am right now.
I'm more inclined to believe that the shit we pump into the atmosphere, combined with the earth changing naturally, is going to cause more extremes. Not warming or cooling, but more extremes more often. More droughts, more floods, more snowstorms, more of anything but normal weather conditions.

To some extent you are correct, but you then take that and go off in a strange direction.
More H2O in the atmosphere leads to higher temperatures, this is true. However, as more moisture accumulates, it leads to cloud cover and rain. This is why you hear on the weather channel "this warm air mass moving in from the south will be bringing with it heavy rains." Warm, humid air brings clouds. More warmth causes more humidity (if over the ocean).
So what happens as that moisture goes up into the sky? Well, it turns into clouds. Those clouds act as a natural barrier to the sun's rays. So with greater cloud cover, the sun can't warm the surface of the earth as much, so evaporation of the oceans occurs at a slower pace. So perhaps there will be another equilibrium that has a higher temperature and higher humidity, but such a state leads to *lower* oceanic levels as the moisture is in the air rather than the ocean. It also means more lush plant life and greater fertile areas worldwide.
Global warming threatens to disrupt our current ways of life, but it does not threaten an end to our species.

Reflective areas reflect the heat, so creating warmer air. This means it is less likely to rain in such places. The air holds onto the moisture it has that much better. Reflective areas are typically desert regions, so those regions will become even dryer. (The Arctic and Antarctic are considered cold deserts, as the total amount of precipitation is extremely low.)
Absorptive areas hold onto the heat. This doesn't strictly cool the air, but it does mean the air isn't getting warmed up by reflected heat. Since the air has (in net) more moisture, it should require less cooling for that moisture to precipitate. This means that areas with lots of plant growth (eg: rainforests) or are dark for some other reason will experience much heavier rainfall, over a larger area.
The total rainfall for the planet will increase, but the regions in which it will fall will shift.

Any time any radiation travels through the air, a certain fraction will get absorbed. This means that all that newly-reflected energy will result in the air becoming much warmer than it would otherwise have done.
This does not mitigate the effects of pollution, but rather augments it. You see, in and of themselves, oxygen and nitrogen air molecules don't absorb a whole lot. Some, but not that much. Nitrous oxide, Sulpher dioxide, Ozone... These aren't so transparent to heat, so the more you have of them, the more the air is going to get warmed up.
Areas that suffer smog often suffer, as a direct result, temperature inversions. These, too, will likely be on the increase.

I would say that the Earth's ecology is more like a pendulum. It is a self-adjusting mechanism, when shoved too far in one direction- it swings back the other way. The harder it is pushed, the further and harder it swings. When left alone, it begins to settle. One day... when the pendulum is no longer pushed by the extinct human species, it may obtain real balance.

That'd be "climate change" changing the wind patterns.
"Global warming" doesn't "produce increased precipitation".
Regional climate is effected by the amount of energy in the atmospheric (and oceanic) systems. Currently scientists affirm that there is an increased amount of energy, retained via the greenhouse effect, in the global climate system. This increase in the amount of energy in the climate system can effect different climates in different ways, including more or less average precipitation, higher or lower temperatures, etc.
Climate change FAQ
Yeah, and the gas in my ass is causing me to eat more beans.
I don't know if global warming exists, and, if it does I don't know what the effects will be. However, I'm a bit cynical, for the following reasons.
1. A lot of scientific theories have been very popular and well accepted for quite a while before they are disproven. Epicycles. The aether. Phlogiston. Eugenics. Cold fusion. The coming ice age in the 70's. So wide acceptance by itself doesn't give me a warm fuzzy feeling.
2. Having been a university professor for a while, I understand the intense conflict of interest that researchers experience. On the one hand, climatologists would like to tell the truth. On the other hand, they know beyond the shadow of a doubt that if they held a conference tomorrow and all agreed that global warming wasn't happening, their lives and the lives of their families would all change for the worse. They would lose funding and graduate students, their salaries would drop, they'd have more trouble publishing papers, they'd have to teach more undergraduate classes, some would not get tenure, etc. So there is a huge incentive to interpret ambiguous data in such a way as to keep the global warming in the news.
3. The data is very noisy and ambiguous. Climatologists are trying to pull a trend out of data that has a lot of natural variation, that has a lot of measurment error, and that is very incomplete. Also, since global warming is now the "standard" view, journal reviewers will examine papers that do not tend to support global warming a lot more carefully than papers that do support global warming. If your paper weakly supports global warming, it is much more likely to be published than a paper that weakly undermines global warming. ("Extraordinary results require extranordinary evidence.")
4. The theory keeps changing. It is not longer just warming. It's almost any change in climate at all. More hurricanes than average? Fewer hurricanes than average? The Sahara is growing? The Sahara is shrinking? The US midwest is getting drier? Getting wetter? The theory of global warming has gotten so flexible that all these scenarios are apparently consistent with it. If a theory predicts anything then it has no predictive power at all.
For those of you that were still in diapers or elementary school, prior to 1988, the scientific community was touting the fact that the world was recovering from a mini-ice age from 1450 to about the 1850s. The sweltering summer of 1988 led a small minority of "scientists" to postulate a "global warming" idea.
How many people know that Krakatoa, in the eruption of 1883 released more "greenhouse" gases than all of mankind has released since? And how many of you know that "greenhouse" gases account for less than 5% of the "greenhouse" effect? Water vapor accounts for 95% of the "greenhouse" effect.
How many people know that Al Gore, in 1997, visited Glacier National Park, and declared the 100 year receding of glaciers as "evidence of global warming" ??? I hate to say it, but 100 years ago, 60 years ago, even 40 years ago, there weren't SUVs driving around.
Global warming might be happening, but suggesting that we puny humans have that much effect in such a short period of time is a wee bit premature. For those of you that keep pointint to Venice, it's SINKING! Venice is a series of islands that have been sinking for a LONG time. Same thing with many other areas. Plus, we've been coming out of an ICE AGE for about 100,000 years.

I saw a great episode of the show Frontline describing how Republicans paid consultants to help them repackage unpolular ideas. A brilliant Republican consultant named Frank Lutz talked about how if you just change the names of things, it can completely change people's opinions.
One example he gave was the difference between "global warming" and "climate change". By now, everyone knows that "global warming" is bad whether or not they know that the scientific community overwhelmingly believes it to be occuring. But "climate change" sounds innocuous so people don't get upset about it.
I find this pretty sinister so I ask you to call it what it is and say "global warming" instead of "climate change".
Oh yeah, "tax burden" instead of "taxes" was another example of a Republican word change designed to convince people to agree with their point of view. Whether or not you think taxes should be higher or lower than their current levels, I find it disturbing that the media seems to have picked up the biased term of "tax burden" instead of the neutral term "taxes".

The book is also a good read (if a bit preachy), but it's conclusion is the most important thing about the book: the message that one must be skeptical, and that well meaning people can be knowing or unknowingly biased to support a scientific theory without much regard to its validity.
Sure it's volatile, but we humans are one quite a big variable. But we're a special variable, because we can conciously control what kind of variable we are. Or try to... Which entire global warming debate is all about. Should we try to control our impact, or just not care, just deal with whatever happens when it happens and accept to economical and humanitarian cost as act of nature.
IMHO it just sounds a tad stupid to not at least try to keep things nice, ignoring the fact that we *do* have a significant impact on many things (eg CO2 levels, which in turn have significant impact on global climate). A bit like not buying a coat for winter (since you have "better" use for the money), and stoically accepting that if you get a flu, then you get a flu and deal with it, but no point worrying about it beforehand, let alone trying to not get the flu in the first place...

Actually, the places with the most long term record of rainfall and pollution are the least developed in the world. They are the north and south poles, where core samples can show relative snow fall (i.e. rainfall) and greenhouse gasses/other forms of pollution. One of the people I worked with did a PhD in the 1980's that showed that there have been substantial increases to the average temperature over the last 5,000 years.

I'm neither here nor there on the topic, and of course we should scientifically know as much as we can, and respond accordingly (not in some pathetic quest to turn the Earth into a static const, but rather to ensure that we're having a controlled impact). All I will say is that there are a lot of believers who will latch onto a cause like global warming with the slightest of pretense -- any reason to clutch a ban and decry the man is perfect.

"None are more hopelessly enslaved than those who falsely believe they are free." -- Goethe
A current theory is that Lake Agassiz, a 'super great lake', catastrophically drained into the upper Atlantic causing a shift in salinity, thus a shift in the temperature current flow, thus a shift in climate.
Consider that for Lake Agassiz to drain or exist at all implies that the continental ice sheet was reteating and that the climate was already warming. The draining of Lake Agassiz was an effect of climate change, not a cause. Also, I find it hard to believe that the Gulf Stream gyre, which operates over the whole of the North Atlantic was suddenly turned on by this event. The northeast circulation of warm surface water is explained by Hadley circulation and coriolis force. Other components of the motion are second order effects.

Why do we put so much faith in climate models that predict catastrophic climate changes xx years from now when we don't have a climate model that can accurately predict the weather 3 days from now?
Just curious.

How are we supposed to come up with a coherent policy when we are warned of the horror of global cooling, then the disaster of global warming, and now the menace of global climate change?
Can we pick a doomsday scenario and stick with it?
