Sentences with phrase «declining snow water»

Long - term climate warming is strongly correlated with declining snow water equivalent and shifts in stream flow throughout the American West and appear to be largely explained by decreased spring accumulation and / or increased spring melt.

I guess I am surprised that with better understanding of the importance of water vapor feedback, sulfate aerosols, black carbon aerosols, more rapid than expected declines in sea ice and attendant decreases in albedo, effects of the deposition of soot and dust on snow and ice decreasing albedo, and a recognition of the importance of GHGs that were probably not considered 30 years ago, that the sensitivity has changed so little over time.

IPCC AR4 WG1 SPM says (under «Fresh water resources and their management» of «C. Current knowledge about future impacts») In the course of the century, water suppries stored in glaciers and snow cover are projected to decline, reducing water availability in regions supplied by meltwater from major mountain ranges, where more than one - sixth of the world population currently lives.

Snow - dependent drainage basins that supply much of the world with water are steadily declining.

Enhanced water vapor absorbs more incoming sunlight and reflection from snow and ice declines.

Those who do come to the Northwest will be faced with an unpleasant reality, she adds, reciting a list of problems expected to strike the region before the turn of the century: regional temperature increases between 5.5 and 9.1 degrees Fahrenheit; drier summers making the Northwest's forests more susceptible to fire; declining snowpack, as more precipitation falls as rain instead of snow at higher elevations, straining regional water supplies and increasing the risk of flooding downstream.

As ice declines in the Arctic and Antarctic regions, melting snow and ice could alter water currents, leading to dramatic changes in the marine environment.

In order of seniority, the seven feedbacks that seem outstanding are: Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, water column mixing, etc..
