Sentences with phrase «changes in albedo carbon»

Not exact matches

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.

That's pretty alarming, especially when considered in the context of other positive feedbacks including changes in albedo from melting icecaps and release of carbon and methane from thawing permafrost.

The change in ice volume and climate changes the planets albedo (how much sunlight is reflected) and affect carbon storage.

, (3) changes in surface albedo of snow & ice due to changes in temperature and deposition of mineral and black carbon particulates, and last, but arguably most significantly (4) the intensity of the positive feedback that comes from the inevitable -LRB-?)

My reasoning was that, iirc, black carbon has played an important role in the ice loss by changing albedo.

Other feedbacks include seasonal shift, latitudinal shift, changes in ice albedo and the carbon sink and many more.

Based on evidence from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g. from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks from changes in water vapour, natural aerosols, clouds and sea ice, slower surface albedo feedbacks from changes in continental ice sheets and vegetation, and climate — GHG feedbacks from changes in natural (land and ocean) carbon sinks.

Broad - scale changes in vegetation in general, and tree loss in particular, have pronounced effects on climate processes through biogeophysical mechanisms such as albedo, evapotranspiration (ET), and carbon dioxide exchange with the atmosphere [11].

He'd been studying changes in Greenland's albedo (the scientific term for the reflectivity of ice), but hadn't focused on the role of black carbon.

This leads me to believe that CO2 forcing is a minor component of the temperature rise (even Hansen in his paper «Global Warming in the 21st century, an Alternative Scenario» has assigned much warming to e.g. black carbon, methane etc, and an inquisitive mind might easily think of others such as albedo change).

And we don't have to go back all that far to get changes in carbon dioxide in the atmosphere and quite unknowable albedo effects.

25 Uncertainties Changes in atmospheric water vapor — Changes in cloudiness — Changes in albedo Carbon budgets Aerosol particles — Direct effects — Impact on clouds — Black carbon
