Human contribution to more-intense precipitation extremes : Nature : Nature Publishing Group

Extremes of weather and climate can have devastating effects on human society and the environment1, 2. Understanding past changes in the characteristics of such events, including recent increases in the intensity of heavy precipitation events over a large part of the Northern Hemisphere land area3, 4, 5, is critical for reliable projections of future changes. Given that atmospheric water-holding capacity is expected to increase roughly exponentially with temperature—and that atmospheric water content is increasing in accord with this theoretical expectation6, 7, 8, 9, 10, 11—it has been suggested that human-influenced global warming may be partly responsible for increases in heavy precipitation3, 5, 7. Because of the limited availability of daily observations, however, most previous studies have examined only the potential detectability of changes in extreme precipitation through model–model comparisons12, 13, 14, 15. Here we show that human-induced increases in greenhouse gases have contributed to the observed intensification of heavy precipitation events found over approximately two-thirds of data-covered parts of Northern Hemisphere land areas. These results are based on a comparison of observed and multi-model simulated changes in extreme precipitation over the latter half of the twentieth century analysed with an optimal fingerprinting technique. Changes in extreme precipitation projected by models, and thus the impacts of future changes in extreme precipitation, may be underestimated because models seem to underestimate the observed increase in heavy precipitation with warming16.

ANybody want to do the honors and go to SOURCEWATCH and check the board of directors/funding sources over at Nature Publishing Group???

Kooky, one would expect such ignorance from you.

This past years we have seen a number of weather events cause large losses of life. We must do something before everything is too late..

You must of missed this Old Crock, you did not respond and seeing how you have been busy insulting me across the boards I thought you might want the opportuntiy to address me calling you a hypocrite, what have you to say Old Crock.

Now if it is so safe, why all the exemptions from existing pollution laws?

But Old Crock, you are proposing Hydraulic Fracturing when it comes to Geothermal. Old Crock shows how the Green Anarchist lies, you see no EPA rules are good for the Green Anarchist but bad for Oil. Hydralic Fracking is good for toxic Geothermal but baaaad for a powerful, rich source of energy such as Oil or Gas.

Old Crock, tell me your suffering the effects of your age and cannot remember what you post. Old Crock is my greatest source to show Old Crock and the Green Anarchists are liars. I have more Old Crock so do not be too angry and fly off the handle and reply to my posts without thinking, I actually have searched and found my next two or three responses. Lets watch and see if Old Crock takes the bait.

And so I am to believe a dumbass poster on an internet message board over the scientists at MIT.

Power from down under

Everywhere on Earth, a few miles below the surface, the bedrock is hot, and the deeper you go the hotter it gets. In some places, water heated by this hot rock comes naturally to the surface or close to it, where it can be easily tapped to drive a turbine and generate electricity.

But where naturally heated water is not available at or near the surface, this process can be recreated by drilling one very deep well to inject water into the ground, and another well nearby to pump that water back to the surface after it has been heated by passing through cracks in the hot rock. Such systems are known as Engineered Geothermal Systems, or EGS.

A 2006 report by an 18-member team led by MIT Professor Jefferson Tester (now emeritus, and working at Cornell University) found that more than 2,000 times the total annual energy use of the United States could be supplied, using existing technology, from EGS systems, and perhaps 10 times as much with improved technology.

Old Crock, list the full article, I followed your link and here it is. How in the hell can you have a discussion about an article we have to buy. How about posting the actual report instead of the press reslease of an article about a study.

Now that is Science, right, basing your opinion on a headline, not the science.

Scientific journals are expensive to produce and publish. However the abstract contains the conclusions. And one can always go to a public library if you really want to know more. You do know what one of those is?

 

[Old Rocks]

While the amplitude of many of those swings is debatable, both ways, the forcings that produced them were far less than the present forcings from the GHGs that we have added to the atmosphere.

$32 per article?

What is their subscriber base.....4?

These guys should work for the government!

 

[Old Rocks]

OK, Mini, so you have no idea what peer reviewed scientific journal are. Not surprising.

Not to mention the looney idiots we've added as well.

 

[Mini 14]

Uh, yeah, I do.

I'm just not inclined to pay $200/year to subscribe, nor $32 per article.

 

[Old Rocks]

Then you can surely read the abstract. That is for free. Or, you could go to a library. Point is, the real scientists that are studying the effects of the GHGs that we are adding to the atmosphere are publishing in peer reviewed scientific journals. And stating that we are already seeing the effects of the additional GHGs. But then, one does not have to be a scientist to see those effects on the current rise in food prices.

its funny how the real scientists can blame everything on CO2. warming, cooling, more rain, less rain. everything is reason for AGW alarmism. they may be short of evidence but they arent short of advocates and bully pulpits.

isnt it odd how these real scientists explain how their models arent accurate in the safe confines of a paywall paper but act like there is no doubt at all when it is for public consumption.

Until you understand all of the variables that affect an outcome, any of the components can be shown to be the cause.

Old Rocks is putting his faith in a science that is in its infancy. He thinks 200 years of data is enough to understand the Earth.

its worse than that. many of the scientists in climate studies are abdicating their duties to science so that they can become advocates for alarmism. it is becoming more and more prevelent for lecturers to point out the fallacies being fed to the public and to express their embarrassment over it. and these are professors who believe in some type of AGW.

But... In March 2000 the meter was "Snow will be a rare and exciting event. Children in 10 years won't know what snow is." -- David Viner, the Climate Research Unit, University of East Angelia.

Yeah, we're supposed to just mindlessly and slavishly keep believing them.

The increase in the ocean temps will cause humidity to rise causing more precip including more rain and more snow.

We saw that this winter.
