WASHINGTON -- A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.
The study shows for the first time how rising carbon dioxide concentrations could affect the entire range of rainfall types on Earth.
Analysis of computer simulations from 14 climate models indicates wet regions of the world, such as the equatorial Pacific Ocean and Asian monsoon regions, will see increases in heavy precipitation because of warming resulting from projected increases in carbon dioxide levels. Arid land areas outside the tropics and many regions with moderate rainfall could become drier.
The analysis provides a new assessment of global warming's impacts on precipitation patterns around the world. The study was accepted for publication in the American Geophysical Union journal Geophysical Research Letters.
"In response to carbon dioxide-induced warming, the global water cycle undergoes a gigantic competition for moisture resulting in a global pattern of increased heavy rain, decreased moderate rain, and prolonged droughts in certain regions," said William Lau-Wanker of NASA's Goddard Space Flight Center in Greenbelt, Md., and lead author of the study.

My attitude is that if NASA doesn’t return to their original pathfinding and prospecting mission, they should be defunded and private industry should be allowed to operate tax free doing the same job till they start showing a profit.
Do these folks use the same computers and same math systems that predicted a warmer than normal 21013 spring? If so they need to go back sooner rather than later and fix a bug or two.
I’d be interested in how global warming affects the growth and decline of Martian polar ice fields.
Seems I remember NASA doing some work in that area at one time.
What does this have to do with Muslim outreach?
Wasn’t that their new mission?
It is a modeling study,IOW it is only as good as the model and the data input in it. So you can get any desired result. This so called study is not worth the paper it’s printed on unless the said paper is really really soft, them it could be used for other, more useful purposes. OTOH, if they had studied the effects of HAARP on the weather patterns and rainfall, we could talk, but then again, not when they use a modeling study...
IOW it is only as good as the model and the data input in it.
An interesting trivia bit is that when plants inhale CO2 through pores in their leaves, they also lose moisture from their pores, moisture which they have brought up from the soil.
However, when there is a greater concentration of CO2 in the air, they don’t have to open their pores as wide, so lose less moisture, so draw less moisture from the soil.
This matters a lot in places with deserts, because the more moisture in the soil, the more plants it can support. And the plants also help fix the moisture in the soil.
So with greater CO2, deserts will start to shrink, which also has a cooling effect on the air above them, that may contribute to more precipitation.
Importantly, about 300 million years ago, most of the Middle East was wet jungle, more like the Amazon River Valley is today.
Give it up you globalist anti-American communist pigs!
IIRC, the formation of the Himalayas when the island that was the Indian subcontinent collided with the Eurasian landmass was what cut off the flow of moist air that had previously flowed over the Sahara and MidEast, and forced it to take a more southerly route. Thus the drying out of North Africa and the MidEast.
“My attitude is that if NASA doesnt return to their original pathfinding and prospecting mission, they should be defunded and private industry should be allowed to operate tax free doing the same job till they start showing a profit.”
I am very sorry to say that I reluctantly agree with you.
I would allow private industry to operate tax free anyway as long as they’re advancing us into space.
Oh no.... Global Wetting!!! We’re all going to drown.
Still with their ridiculous computer models that have no relation to the real world.
Haven’t they learned anything about “projections” about climate change?
Didn’t they notice that the CO2-based model for warming has been messed up for the past 10-15 years?
Oh, I forgot. It’s not about science, it’s about jobs. Make it look as if you are going something useful, even if it’s a bunch of garbage that will fail totally. What does it matter? No one will remember it or report it.
I wonder if anyone predicted the cold spring? Or the all-time record low number of tornadoes in the last year.
NASA - 2013 - No Astronauts in Space Anymore
obama can’t have us with an active working space program. too good for the economy, national morale, and would reverse us losing our superpower status.
how else could we get fleeced by the soviets - yes they’re stil soviets with a capitalist/black market veneer - for 70 million a pop for each spaceman to the iss?!?
The trees hate all this anti-CO2 talk.
