Sentences with phrase «feedback under climate change»

However, possible use of seasonal snow albedo feedback to evaluate snow albedo feedback under climate change conditions is of course dependent upon the realism of the correlation between the two feedbacks suggested by GCMs (Figure 8.16).

Model performance in reproducing the observed seasonal cycle of land snow cover may provide an indirect evaluation of the simulated snow - albedo feedback under climate change.

Greening already under way Isla Myers - Smith, a lecturer at the University of Edinburgh who did not participate in the research, said the study is a «major advance» because it is the first to link such a broad range of vegetation changes with several climate feedbacks in the Arctic.

If so, then the Stefan - Boltzmann equation applied to the observed temperature change (and projected temperature change under double CO2) should approximately tell you the total forcing incorporating climate system feedbacks?

In climate change experiments with our LES framework, the Cu regime shows a modest positive shortwave feedback under warming, while the Sc and Sc - over-Cu regimes both show strong but state - dependent positive shortwave feedbacks, with a possible break - up of Sc layers in very warm climates.

Changes in vegetation in northern Alaska under scenarios of climate change, 2003 - 2100: Implications for climate feedbacks

«The Earth's climate system is highly nonlinear: inputs and outputs are not proportional, change is often episodic and abrupt, rather than slow and gradual, and multiple equilibria are the norm... there is a relatively poor understanding of the different types of nonlinearities, how they manifest under various conditions, and whether they reflect a climate system driven by astronomical forcings, by internal feedbacks, or by a combination of both... [We] suggest a robust alternative to prediction that is based on using integrated assessments within the framework of vulnerability studies... It is imperative that the Earth's climate system research community embraces this nonlinear paradigm if we are to move forward in the assessment of the human influence on climate.»

As high latitudes warm under climate change, they are likely to release more methane, which will in turn boost warming, in what is known as a positive feedback.
