Sentences with phrase «albedo decrease»

The scientific community had an understanding that overall albedo decreases with declining ice, but the new study is distinctive for putting a number on the decline.
With regard to Dr Tobis» observation that: «there's a something on the order of a 10 % chance that we may have already passed the 2 C mark by any reasonable definition» the evidence of a study of Albedo Loss published last January appears to put the issue beyond doubt: «Observational determination of albedo decrease caused by vanishing Arctic sea ice» (Kristina Pistone, Ian Eisenman, and V. Ramanathan)
«Scientists have talked about Arctic melting and albedo decrease for nearly 50 years,» said Ramanathan, a distinguished professor of climate and atmospheric sciences at Scripps who has previously conducted similar research on the global dimming effects of aerosols.
The Amazon and other rainforests drying out The Siberian bogs (the size of germany, france and the UK combined) start to release methane in accelerating annual volumes Ice Albedo decreasing Ocean conveyor (thermohaline systems to some) weakening due to freshening of the seas
For instance, Han et al. (1998) showed that cloud albedo decreases with decreasing droplet size for the optically thinner clouds over the oceans.
Ice albedo decreases further, to between 20 % and 50 %, when it has high concentrations of impurities, as is common in the ablation zone.
Cloud amount and albedo decreased over mid-latitude oceans in both hemispheres (especially over the North Atlantic), over the southeast Indian Ocean, and in a northwest - to - southeast line stretching across the central tropical South Pacific.»
Because each process responds positively to warming (i.e., albedo decreases as warming increases), they are all likely to become increasingly important in the future.

«Scientists have talked about Arctic melting and albedo decrease for nearly 50 years,» said Ramanathan, a distinguished professor of climate and atmospheric sciences who has previously conducted similar research on the global dimming effects of aerosols.
So for example deglaciation warmed global mean temps by about 5 C over 10k years with a radiative forcing of about 6.5 W / m2 (total of both GHG increases and albedo decreases).
As albedo decreases, heating and temperature increase.
The sun removed ice extent and Albedo decreased and Earth Warmed.
There will be some change to the carbon sink, but there's no real understanding if it will be positive or negative climatologically, as massive vegetative increases could be beneficial as a carbon sink, but albedo decreases might be a net thermal increase.
«The decrease in Earth's reflectance from 1984 to 2000 translates into an albedo decrease equivalent to a forcing of 6.8 W / m ^ 2.
However, if we cross off the oddballs here, we see that the second tier of the tree decomposes to just three mechanisms, solar irradiance increase, albedo decrease, and heat reservoir release.
Rather, an albedo decrease (3.4 W / m ² to 6.8 W / m ²) was driving the warming for the period in question.
as an albedo decrease of only 1 %, bringing the Earth's albedo from 30 % to 29 %, would cause an increase in the black - body radiative equilibrium temperature of about 1 °C, which is the same amount a doubling of CO2 will give without the unproven feedbacks.
