Sentences with phrase «arctic albedo feedback»

Not exact matches

Virtually ice - free summers in the arctic sea could well arrive by 2030, with troubling implications for accelerated albedo feedback and possibly disruptive changes in the jet stream.

In the NH a lot of land surrounding the arctic ocean is subject to the combination of decrease in seasonal snow cover (with climate warming), and decreasing albedo due to vegetation feedbacks.

Both these factors (as well as sea ice albedo feedbacks, give the arctic region very strong positive feedback which regionally amplify the GW signal.

Apart albedo, shouldn't we expect a classical water vapour feedback (and so DLF forcing) as arctic ice is melting and arctic seas / ocean warming?

Subject of some specific concern about global warming because of large temperature rises predicted for the arctic, and because of some arctic - specific feedback effects (e.g. the albedo feedback following loss of arctic sea ice).

Ice - albedo feedback, he added, could give considerably greater warming in arctic regions.

Hence, one gets a positive feedback whereby the warming of the arctic leads to ice melting which lowers the albedo of the earth and thereby leads to further warming of the arctic (and global climate system as a whole).

The increased albedo from melting arctic ice should not matter very much, but the newly exposed cold surface water might absorb extra carbon dioxide, acting as a negative feedback on the whole system.
