Desert Amplification in a Warming Climate
Here I analyze the observed and projected surface temperature anomalies over land between 50°S-50°N for the period 1950-2099 by large-scale ecoregion and find strongest warming consistently and persistently seen over driest ecoregions such as the Sahara desert and the Arabian Peninsula during various 30-year periods, pointing to desert amplification in a warming climate. This amplification enha...
متن کاملTrophic amplification of climate warming
Ecosystems can alternate suddenly between contrasting persistent states due to internal processes or external drivers. It is important to understand the mechanisms by which these shifts occur, especially in exploited ecosystems. There have been several abrupt marine ecosystem shifts attributed either to fishing, recent climate change or a combination of these two drivers. We show that temperatu...
متن کاملHurricanes in a Warming Climate
There are fundamental differences between the climate of the Southern and Northern Hemispheres. Largely, these differences are dictated by the obvious differences in the geography of the two hemispheres: the Northern Hemisphere is about 50% land, whereas about 90% of the Southern Hemisphere is ocean. This asymmetry gives a much larger seasonal cycle in the Northern Hemisphere (NH) and reduces t...
متن کاملArctic tropospheric warming amplification?
Relative rates of temperature change between the troposphere and surface, and the mechanisms that produce these changes, have long been a contentious issue. Graversen et al., predicated upon the ERA-40 reanalysis, report polar tropospheric amplification of surface warming and attempt to explain this finding dynamically. Here we show (1) that data from satellites and weather balloons indicate th...
متن کاملAltered hydrologic feedback in a warming climate introduces a warming hole
[1] In the last 25 years of the 20th century most major land regions experienced a summer warming trend, but the central U.S. cooled by 0.2–0.8 K. In contrast most climate projections using GCMs show warming for all continental interiors including North America. We examined this discrepancy by using a regional climate model and found a circulation-precipitation coupling under enhanced greenhous...
