Sentences with phrase «much global rainfall»

Not exact matches

Cory Cleveland, a UM professor of terrestrial ecosystem ecology, said that previous research in the wet tropics — where much of global forest productivity occurs — indicates that the increased rainfall that may occur with climate change would cause declines in plant growth.

[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?)

This in turn may mean that something other than global temperature - for example, rainfall - has changed much more in X than in Y.

With Spring on the way, with so much moisture still bleeding off the Pacific, with a record level of global warming greatly amping up the hydrological cycle, and with a trough development tendency setting up for this region — this particular extreme rainfall event may, sadly, be but the first of many this season.

In fact, scientists generally agree that global warming will ensure diminished rainfall and ever more frequent droughts over much of Africa and the Middle East.

Indeed, rainfall data reveal significant increases of heavy precipitation over much of Northern Hemisphere land and in the tropics (27) and attribution studies link this intensification of rainfall and floods to human - made global warming (28 ⇓ — 30).
