Rain and Climate

It’s been raining, unusually hard, in several parts of the world–England, China, India, and parts of the U.S.–and, quite by coincidence, there is a paper coming in this Thursday’s edition of the journal Nature, reporting that, "for the first time, climate scientists have clearly detected the human fingerprint on changing global precipitation patterns over the last century." 

That phrase comes from the lead authors at Environment Canada, who worked with other scientists in Britain, Japan and the U.S.  They compared rainfall patterns since 1925 with the changes that fourteen different computer models of the climate said ought to have happened, and found that in large parts of the world, they match pretty well.

"We show," they write in the Nature paper, "that anthropogenic forcing [i.e., changes caused by human activity] has had a detectable influence on observed changes in average precipitation within latitudinal bands, and that these changes cannot be explained by internal climate variability or natural forcing."

They found much of the Northern Hemisphere and the southern tropics getting wetter over time, and some tropical regions just north of the Equator–notably the Sahel region in Africa–getting drier.

The abstract of the paper is HERE.  The full paper is not online without a subscription, but Nature does have a news piece of its own HERE

"This is a very important paper," says climate researcher Myles Allen of Oxford, in the Nature news piece. "It identifies the fingerprint of human influence."

There are some important caveats to remember:

–The rainfall records used in the paper are only on land (records at sea, before weather satellites, are spotty), so about two thirds of the planet cannot be measured. 

–Weather is not climate, so it’s dangerous to say the bad rains today are necessarily connected with global changes.

–Could there be other factors at play?  Yes, of course, but this paper found the best match between actual rainfall and the computer models came when the models accounted for "anthropogenic" factors–the increase in greenhouse gases such as carbon dioxide.

There’s been a lot of discussion over whether variations in the Sun’s intensity could explain the warming of the last 20 years.  To that end, there’s now a paper in Proceedings of the Royal Society, by a pair of British and Swiss scientists, saying that if anything, "all the trends in the Sun that could have had an influence on the Earth’s climate have been in the opposite direction to that required to explain the observed rise in glboal mean temperatures."  The full paper is HERE.

Climate is always politically contentious.  Thoughts welcomed.

Anyone ever hear about Global Dimming? It is another man-made companion global problem that oddly enough counter-balances Global warming but is equally as harmful to mankind… look it up.

I am not sure why the author of this piece would use the term contentious. There is no doubt amongst people with training in atmospheric dynamics/chemistry that anthropogenic forcing is the primary cause of global warming. Sounds like ABC might be afraid of offending the administration more than they feel obligated to present the simple and obvious facts.

Where there is no rain (forest fires in several states) that is a sure sign of global warming. Where the same rain that did not fall in those states, is falling and causing floods, that, of course, is also a sure sign of global warming.
Anyone with any serious scientific training in stupidology will clearly see that we have a serious global rise in ChickenLittleitis on a global scale. Run for your life! Cluck, cluck!

Not only should we cut our energy consumption to lessen global climate change, we should do it so we don’t have to stick our nose in the Middle East hornet’s nest every day of the year. The OPEC countries need our expertise and productivity more than we need their oil!

Computer models huh? Just because you solve a few differential equations on a computer it is supposed to imply that you are getting the TRUTH? Unless you can start predicting the future (as opposed to “predicting” the past) SUCCESSFULLY AND REPEATEDLY it is not science, it is simply religion/politics. I think the wall-street modelers have finally moved over to modeling weather. You get paid no matter whether you are right or wrong because average person thinks sophisticated (i.e., 17th century math) and computers can’t be wrong.
Incidentally, liberals think global warming is man-made and conservatives think it is not man-made. So that is how far this “science” has come. Of course there is no conservative and liberal branches of quantum mechanics or newtons laws. Is there? Because they are SCIENCE not religion or politics.
Just getting irritated by these extreme hippies. And a note against conservatives: Just because we are not causing global warming does not mean we should force ourselves to be energy inefficient or cause other sorts of pollution. Can we get a little balanced thought from the media please?

In science, statistical models are used to FORECAST the likelihood of an event happening, not PREDICT it like some astrologer/Defense Department undersecretary. And frankly, I don’t see the word “predict” in this piece.
BTW, Wall Street makes very good bets based on weather (after all, they have the money and they’re not hobbled by political appointees of the Bush administration) and the are driving the prices of resources steadily upward. If Hysteriawatch won’t listen to science, perhaps he’ll listen to his frat-boy betters at the investment banks.

Isn’t it interesting that the authors
note: –Weather is not climate, so it’s dangerous to say the bad rains today are necessarily connected with global changes.
What are “bad rains” versus “good rains?

Posted by: Chuck | July 23, 2007, 5:02 pm 5:02 pm

Two years ago it was all the hurricanes that proved global warming was here. So, no hurricanes to speak of during the past two years…….
Is gobal warming over?
I don’t think it is that simple (rain which has always been cyclical) to prove and scientists are just trying to make a buck.

I’m not a scientist but I am a thinker; Like humans, the dinosaurs grew into huge numbers during their time and I wonder if they effected their environment too? The great herds of herbivores would have created large amounts of greenhouse gasses. Maybe climate change is an unavoidable part of evolution itself? Creatures with walnuts for brains managed to survive over 300 million years, I can only hope humans can adjust and survive too.

Posted by: tony | July 23, 2007, 5:04 pm 5:04 pm

Hey Chuck, I think the “bad rains” are the flooding rains and the “good rains” are the rains that make flowers grow. All in all, it has been a strange summer. My area, the Hampton Roads region of Virginia, has been somewhat dry, not as much rain as in previous years, and has been significantly hotter as well. Also, what happened to this “active” hurricane season? Shouldn’t we have had 2 or 3 storms by now??

Posted by: Lawrence | July 23, 2007, 5:13 pm 5:13 pm

The human cost of global climate change will mostly be borne those poor countries unable to adjust their infrastructure to climate changes, many of whom will suffer more drought. The advanced nations of the West and Asia will be more likely to handle this. Of course, there will be a lot of hardship in the US anyway. I spend a lot of time at the shore and the rates of loss are alarming, even in my short memory.
So it’s a moral imperative that we adopt lower-energy lifestyles, which also happen to be good for the bottom line. If you’re not alarmed by the rise in your utility bills recently, than you are very rich indeed. I’m lucky. Living in NYC I take the subway to work everyday, saving huge amounts of money, plus I get to read.

Posted by: rob | July 23, 2007, 5:14 pm 5:14 pm

Sorry for the double post, but saw Tony’s after I had posted. We won’t survive much longer if we don’t get our heads out of our collective butts and realize that our current lifestyle around the world will kill us off. Hopefully we’ll do this soon, before some crazy with an idea that another country “might” have a nuke starts a war. Oh wait, that’s already happened. Anyway. I too have hopes that humanity will survive long term and gain the ability to leave this planet and seek homes amoung the various other star systems we keep finding. Only time will tell.

Ever heard of quantum mechanics? It is all probabilities (not wave functions) that are observed. And of course they have been predicted up to the 10^-19 decimal place using “probabilities” (a la Q.E.D.). Those are PREDICTIONS using statistics. Of course your high school level math is not cutting it anymore.
Btw, which mutual fund company is beating the market every quarter using quantitative analysis? Ever heard of LTCM?? These monte carlo based simulations went from Physics (SCIENCE) to dummies at wall street and now to same caliber people in weather “science”.
Of course, liberals will keep calling random “forecasting” a science without ever bothering to check if they can predict a damn thing in the future correctly (eg trajectory, frequency of hurricanes, El Nino). Have fun selling your idiotic propaganda.

I don’t mean to sound like a crazy hippie from the 60′s but wouldn’t it be great if all the powerful countries would come together and spend their energy in space exploration rather than wars? We could be moving millions of people to other planets and help guarantee or existence as a species in the universe.

Someone said …
“In science, statistical models are used to FORECAST the likelihood of an event happening”
So, when you are typing your messages were you forecasting that the exact message would be entered the way you typed and then transmitted from your computer over to the server hosting this blog and appear to other users? You don’t believe there are any certainties I take it as in math or computer languages or physics of computer hardware? Should we change newton’s laws to Newton’s Forecasts?

H:
Hm? My point seems to stand. The investment houses are making long bets on resource prices going up, and so far it’s paid off pretty well for them. It’s likely to continue as long as people want to eat, and obstructionists block any reasonable emissions regulations. I’m not BLAMING or attacking them, I’m no Marxist, I’m just saying we should have seen the writing on the wall.
And quantum mechanics? I suppose the mathematicians who do that stuff do in fact PREDICT what will happen if their model turns out one way or another, but it’s pretty much paper to paper. Forecasting applies to the real world.
And don’t try and put your opponents in a box. They’re not offering to PREDICT, their offering a liklihood. They don’t guarantee it, anymore than the insurance company guarantees you a long life when you buy a policy.
And the quants at the exchanges do verrrry well without your opinion of their skills, thank you very much.

The weather in Arkansas has been cooler than normal and wet….we’ve not seen the rain to the extent that northern Texas and parts of Oklahoma saw, but we had a lot during June/July, the river is just now below flood stage after weeks of being over. We’ve gone over a week now without rain, but the temps are staying in the lower 90′s, as compared to over 100 in past years during July. I think that our weather changes are proof of global warming to an extent, and I also think they are proof of evolution. Our planet is changing…it just doesn’t change “overnight”, which in God’s terms may be 4 or 5 generations in people terms…who knows what His schedule for change is? Anyway, we should conserve, we should preserve, but we cannot change the fact that the world is evolving around us, we will just have to adapt or go like the dinosaurs did.

Fortunatley most Americans are not as complacent and fatalistic. As far as I’m concerned, the only thing in the way of halting this trend is adequate emisssions regulations, and the only things standing in the way of that are the President and the special interests (including a number of Democrats) in Congress.

Posted by: rob | July 23, 2007, 5:52 pm 5:52 pm

(I personally remain optimistic. I think there’s plenty of opportunities to slow this down and eventually reverse it. People just have have to adjust their lifestyles. Did our forefathers have air conditioners? Shopping malls? SUVS? Nope….and they did pretty well.)

Posted by: rob | July 23, 2007, 6:04 pm 6:04 pm

You all sound like very intelligent people… but I think it is as simple as:
Human pollution is causing warming of the earth, which is causing the ice caps to melt, which is causing the oceans to flood with more water, which is causing the clouds to evaporate more water, which is causing more rain.
Right?

Posted by: holli | July 23, 2007, 6:06 pm 6:06 pm

Hmmm. But even the forecasters get it right once in a while, with or without valid science to back them up. Just because a forecast or prediction based on some scientific understanding may not be correct all the time, is that any justification for ignoring it completely, especially if it is related to the potential death of our species and the entire planet due to global warming? It just doesn’t make sense. I don’t care if you’re liberal or conservative, if the weather report says it’s going to rain buckets tomorrow, you’re going to take an umbrella with you, aren’t you? And when it doesn’t rain, what happens? You sigh in relief and thank the heanevs for another nice day. Why then do people take such a polarized view on global warming when the rationale behind it is exactly the same? Whether you believe the science or not, wouldn’t it be better to err on the side of caution and do something about it now when we still have a chance to correct things instead of waiting until the damage and devastation is potentially irreversible, and we all die? Frankly, anyone who chooses to do nothing about their carbon footprint given all of the SCIENCE regarding our excessive pollution on this planet is just being selfish, greedy and LAZY, which just happens to typify the entire so-called Conservative agenda these days. Expend the least amount of effort possible to make the most amount of money at the expense of others that are less fortunate than ourselves. Come on, people. It’s time to wake up. Stop thinking about yourself for once and do something to contribute to the greater good of humanity, no matter what your political bias is. This kind of change has to come from EVERYONE, not just the poor or the rich, who we’ve seen throughout history don’t like to do anything unless they’re sufficiently motivated, which usually requires the use of guns or guillotines.

Posted by: voiceofreason | July 23, 2007, 6:09 pm 6:09 pm

1. Natural processes (the 10,000 year output cycle of the sun) are causing the oceans to warm and release more of their carbon dioxide into the atmosphere.
2. This natural process causes Al Gore to hyperventalate, thus releasing mass quantities of carbon dioxide into the atmosphere, and to provide a ruse for his “carbon-credits” idiot tax on the unsuspecting population.
3. Plants and trees utilize this extra carbon dioxide as plant food, and grow much more rapidly that before.

Posted by: One_American | July 23, 2007, 6:26 pm 6:26 pm

Yes this is great, another scientist who draws a conclusion then finds data to support their argument.
How many times does science have to change their thinking over the years before people stop accepting science at face value. The climate change is nothing new, and doesn’t have anything to do with “our footprint.”

Posted by: joe | July 23, 2007, 6:55 pm 6:55 pm

As soon as Al Gore decides what the temperature the earth should be he should let us know. The only thing certain about the earth is that is a dynamic process constantly changing and evolving. There is no correct temperature for the earth. It is a constantly moving target and no matter what Al Gore or the U. N. says we cannot effect the weather. We should of course use less stuff in all facets of our lives, however, even if we do, the earth will continue to heat and cool at it’s own pace no matter what we do. Sun spots and volcanoes have much more effect than man will ever have on the earths temperature.

Posted by: Casey | July 23, 2007, 6:56 pm 6:56 pm

The are only two reasons why anthropogenic global warming is “contentious:” special interest investment in the causes, and a massive public ignorance of science (amply demonstrated in messages posted here… the guy who says, I’m not a scientist but I think really takes the prize).
Many good articles and links on related issues–by real scientists–there is no reason anyone for anyone to remain ignorant on these issues.

To all the naysayers that debunk science with their own patholigical rationale based on faith, lack of understanding or a propensity for believing propaganda generated by the status quo that wants to do nothing to solve the world’s problems that were created by them in the first place, I have only one thing to say to you:
Learn to swim!
For the sake of humanity and the future of this planet I can only hope all you naysayers live on the coast.

holli – At first glance your synopsis seems oversimplified, but I think in fact that you are right on the money. The earth is currently overpopulated and it has gotten to the point where mother nature can no longer counter what we are doing to the planet. Everyone thinks that aids, the bird flu, and other epidemics are a human tragedy, and they definitely are, but they may in fact thin out enough of us to bring us back in balance with what nature intends.

Posted by: Tom | July 23, 2007, 8:25 pm 8:25 pm

Wow! According to these computer models, no humans live in the southern hemisphere! AND rain =global warming? These models are SO scientific, who KNEW?? I guess by global warming they just mean the free, democratic societies. Would it be too much to ask ANY of these geniuses when it will actually show up in reality? Like because of global warming, will we have a reduction in the number of people who freeze to death in winter? Of course not, that does not appear on their computer! How about, since hurricanes only happen during warming, what happens when there are none?? Cooling?? Now that science is reported only when it fits a political agenda, forget any objectivity there either. People who can’t tell us the temperature in 10 days claim they can tell us what it will be in 10,000 days. Amazing! Oh, and W.R. Johnson, everyone I know who lives on the coast has told me the water level has not changed in all the time they have lived there, which is a very long time in some cases.

You’re right off the money and nature hardly requires your representation. Everything is fine the way it is. It rains, earth gets warmer, then colder – whatever. Even the craziest hippie liberal intuitively knows that humans have no measurable impact on global climate….as they didn’t during the last few hundred ice ages. The whole human caused global warming fad is a fragile group of theories that will NEVER hold up to any serious scientific scrutiny. We’ve known for decades that ice cores are not a reliable way to measure atmospheric CO2 and yet there it is, the center piece of their whole mess…..even though we also know there is no consistent relationship between even those phony ice core CO2 levels and global temperature. The climate has never been constant and the earth is 4.5 billion years old. We don’t matter a bit – get over it.

Posted by: cheesetopping69 | July 23, 2007, 8:49 pm 8:49 pm

THERE IS NO CONSENSUS. I’ve met climatologists who are very skeptical about the global warming hype but they’re not being heard. Seems the media has no interest in talking to them.
Spare yourselves the embarrassment this will eventually cause and don’t fall for the nonsense. After all, there used to be lots of folks who absolutely insisted that the world was flat.
Man has always had delusions of grandeur. This just one more example.

Posted by: debunkerdude | July 23, 2007, 10:53 pm 10:53 pm

Are they predicting the past or the future? Why can’t they get the hurricane forecast right for a particular year, just six months out? They have known a lot more about hurricanes for a longer time, than they do global warming.
Even if humans are having this effect, the point is, how does anyone know what the Earth’s reaction will be, exactly? Some of these scientists are making statements about conditions decades from now. Why in the World then, can’t they get the weather forecast right a few days from now? They can’t even predict a cold front developing more than a few days out.

Posted by: SteveS | July 23, 2007, 11:05 pm 11:05 pm

man’s total impact on global warming and greenhouse gasses contributes less than 3%. Even if man stopped using fossil fuels altogether, the climate would continue to warm at the same rate.

Posted by: Steve | July 23, 2007, 11:11 pm 11:11 pm

Global warming and cooling trends have been going on forever, including a mini ice-age only 300 years ago. Accurate temperature recording dates back a mere 118 years, pretty small on a planet that is billions of years old. What is more ignorant…man thinking he is impacting the global weather patterns or man thinking he can influence them?

Posted by: Bill | July 23, 2007, 11:15 pm 11:15 pm

Global warming is happening. It is a natural cyclical event. Man’s impact on this cyclical change is miniscule. Global warming has been hyped by poor countries seeking influence over rich ones. Political hacks like Gore and self important meteorologists use global warming as a tool to line their own pockets and project their influence. Don’t buy into the hype, research things for yourself.

Posted by: J. Seinfeld | July 23, 2007, 11:19 pm 11:19 pm

It is interesting to note that it appears only globar warming attracts the ignorant and vociferous opinions of the uneducated hacks, who “dispute” the long established facts in weather science, at a knowledge level of a badly trained monkey.
Why don’t these people congregate on physics sites, loudly proclaiming impossibility of electrons being both here and there at the same time and ridiculing probabily functions?
It is a mystery.

Are we to respect scientists anymore or not? They constantly ascribe to global warming any condition that is not like yesterday. We have had horrific floods and droughts before and they had better soon show real evidence or the world will turn them off because we all know most of them are on the take financially for all their doom forcasts.

==Even if man stopped using fossil fuels altogether, the climate would continue to warm at the same rate.==
Right. The amount of man-made CO2 in the atmosphere is so high, the warming cycle will continue long after we are gone from this planet.

Posted by: Dimitry | July 23, 2007, 11:53 pm 11:53 pm

==They constantly ascribe to global warming any condition that is not like yesterday.==
That’s a lie pal. Scientists who publish in peer-reviewed journals (unlike, say, Michael Creiton) never do that. They calculate a significance level of a statistical effect, based on volumes of data extending back decades and sometimes centuries.
What the climate models are predicting is the global warming accentuating the DIFFERENCES in regional climates. Coastal areas getting wetter, inland areas drier. That may be way too complicated concept though, judging by the many comments on this blog.
==We have had horrific floods and droughts before and they had better soon show real evidence or the world will turn them off because we all know most of them are on the take financially for all their doom forcasts.==
The ones that are on the take are a couple of “scientists” (out of many hundreds), who have been specifically funded by the oil companies to publish contrary “studies” disputing everything and anything in order to confuse the semi-illiterate public into thinking there is “scientific controversy” over globa warming.

==total impact on global warming and greenhouse gasses contributes less than 3%==
Another cheap parlor trick by conservatives to reinforce their position by lending an air of authority to their deception through the quoting of statistics. When you peel back the layers, however, you discover that these so-called statistics are not only false, but they were most likely made up by the very person making the argument. And what’s really pathological about it is the rest of the conservative army picks up that juicy soundbite of nonsense and spreads it around like gospel. Just have a look at any of the blogs sponsored by Bill O’Reilly, Rush Limbaugh, Fox News, Sean Hannity and that wretch Ann Coulter. Isn’t it curious how they all seem to be echoing the same viewpoint and using the same quoted stories as evidence and support for their arguments? This trick is getting old, seriously.
In particular, I like this item: “there is about 30% more carbon dioxide in the air today than there was about 150 years ago”. Hmmm. What could have possibly happened 150 years ago that would create an increase in CO2 levels? How about the discovery of oil and its use in combustion engines to fuel the Industrial Revolution and put all those fancy automobiles on the highway? Naw. There couldn’t be any causal relationship between burning oil and increased CO2 levels any more than there is a genetic link between primates and human beings because evolution doesn’t exist. Anyone who believes that is living in a big glass bubble.
If you dispute the effect of CO2 building in the fate of the planet, why don’t you do some research on Venus. It’s atmosphere is 100% CO2. But the kicker is it wasn’t always that way. In fact, at one point it had water and may have supported life in some capacity. Because the CO2 levels kept building up, the planet got hotter, which caused more water to boil from the planets surface, causing more heat to be trapped in the atmosphere, which in turn allowed more CO2 to build up, thereby baking more water out of the surface until it eventually depletes all of the water from the planet leaving an atmosphere entirely composed of CO2. It was, in fact, the study of Venus in the 60′s that generated a lot of interest in the Greenhouse Effect, especially given the makeup of our own atmosphere. Once the cycle starts, it’s almost impossible to reverse it. Check the wiki and pay attention to runaway greenhouse effect
Have we started the cycle? No? How can you be sure? Now you know how the story ends, what are you going to do about it?

Voiceofreason, interesting observation that epidemics and other problems will help even out the status quo and bring about a balance of nature (evolution), in reducing the number of humans on the planet. I disagree that the planet is “overpopulated.” It is merely a matter of managing resources. More on that below.
One article reported by a journalist, almost as ignorant of the facts as the rest of us Americans, does not prove or disprove the cause or extent of global warming. Whether it’s human-caused or not can be argued by most laymen (including many politicians, spinning as much as they want) until everyone is blue in the face. The “causes” only have to be explored to determine what the extent of global warming entails, how much we can accurately predict (which so far, in many ways, has reached beyond scientific predictions in past years), so we can prepare for its repurcussions, prevent it as much as possible, and avoid the results, as much as we can. It’s also impossible to ignore that China and America are the 2 largest contributors to fossil fuel emissions on the planet, both to be blamed for mismanagement of resources, and both “responsible” because of it. And which parts of humanity will suffer the most? The poorest nations that will be unable to defend themselves or prepare for what global warming is and will continue to do. It’s hard to believe that we Americans can brag to be the greatest nation on the planet and be so selfish. As soon as we’re done building the next 600 versions of the iPod, video game systems, buying the next desperately-needed generation of HD devices, and producing 200 more great seasons of quality movie and television entertainment, the common man in America might be ready to help his neighbor, educate himself and his children better, and actively devote more to helping their community, their nation, and the world; that would be a truly “global” community. In many ways, America sits among the flies of its self-created manure pile (at least this is probably how many other nations view us), gluttonous and lazy.
It is possible to manage the resources on this planet much better. It’s starts with every single individual, and Americans have the most resources — time and energy-wise — right in their own hands to do so.

We can reduce the amount of methane in the atmosphere if we lowered the quantity of livestock especially since we over make meat and dairy.
