Sentences with phrase «causing evapotranspiration»

Event attribution analysis suggests that human induced greenhouse gas increases may also have contributed by causing evapotranspiration rates to be higher than they would have been under pre-industrial conditions.

The thing to ask is how do they know that the tree ring growth from the past wasn't stunted as a result of warmer temps causing evapotranspiration.

Not exact matches

Their analysis reveals that the conversion of broadleaved forests to coniferous forests caused significant changes in evapotranspiration, the evaporation of water through leaves, and albedo, the amount of solar energy reflected from the Earth back into space.

Concentrating on CO2 ppm gain causing (positive feedback) increased temperature is wrong — and they can't understand (using their same reasoning) the negative feedback of CO2 enrichment — a large part of this evapotranspiration.

There is little evidence for a human influence on precipitation deficits, but a lot of evidence for a human fingerprint on surface soil moisture deficits — starting with increased evapotranspiration caused by higher temperatures.

Key uncertainties involve: 1) the degree to which increases in evapotranspiration versus permafrost thaw are leading to drier landscapes; 2) the degree to which it is these drier landscapes associated with permafrost thaw, versus more severe fire weather associated with climate change, that is leading to more wildfire; 3) the degree to which the costs of the maintenance of infrastructure are associated with permafrost thaw caused by climate change versus disturbance of permafrost due to other human activities; and 4) the degree to which climate change is causing Alaska to be a sink versus a source of greenhouse gases to the atmosphere.

Vegetation cover changes caused by land use can alter regional and global climate through both biogeochemical (emissions of greenhouse gases and aerosols) and biogeophysical (albedo, evapotranspiration, and surface roughness) feedbacks with the atmosphere, with reverse effects following land abandonment, reforestation, and other vegetation recoveries (107).

27, Steve Fish: Water vapor from evapotranspiration has to rise upward until the lapse rate causes condensation back to water.
