Sentences with phrase «reduce global rainfall»

The sulfates would slow or reverse the recovery of the ozone layer; they might also reduce global rainfall, and the rain that did fall would be more acidic.

Global climate models find that rainfall in northeast Brazil is expected to decrease in the coming decades, and some rivers could see flows reduced by 60 to 70 percent, he said.

The amount that worldwide rainfall would be reduced by using space mirrors or sulfur particles to mitigate global warming, according to a paper published in Proceedings of the National Academy of Sciences.

Stirling co-author and Professor of Ecology, Alastair Jump, said: «By pinpointing specific traits in trees that determine how at risk they are from drought, we can better understand global patterns of tree mortality and how the world's forests are reacting to rising temperatures and reduced rainfall.

Taking into account all 20 models, the spread of results reduces when the scientists looked at the rainfall changes per degree of global warming independent of the exact time path of the warming.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
