How will Earth's surface temperature change in future decades?
Reliable forecasts of climate change in the immediate future are difficult, especially on regional scales, where natural climate variations may amplify or mitigate anthropogenic warming in ways that...
View ArticleAnthropogenic forcing dominates sea level rise since 1850
The rate of sea level rise and its causes are topics of active debate. Here we use a delayed response statistical model to attribute the past 1000 years of sea level variability to various natural...
View ArticleIs the airborne fraction of anthropogenic CO2 emissions increasing?
Several recent studies have highlighted the possibility that the oceans and terrestrial ecosystems have started loosing part of their ability to sequester a large proportion of the anthropogenic CO2...

A strong bout of natural cooling in 2008
Cooler North American temperatures in 2008 resulted from a strong natural effect, and the overall warming trend that has been observed since 1970 is likely to resume, according to this study. Using...

Amazon forests did not green?up during the 2005 drought
A drought that happens once in a hundred years had little negative or positive effect on the Amazon rainforest according to this study led by Arindam Samanta from Boston University. Its results are...

Amazon forests did not green?up during the 2005 drought
The sensitivity of Amazon rainforests to dry?season droughts is still poorly understood, with reports of enhanced tree mortality and forest fires on one hand, and excessive forest greening on the...

Two opposing effects of absorbing aerosols on global-mean precipitation
Absorbing aerosols affect global-mean precipitation primarily in two ways. They give rise to stronger shortwave atmospheric heating, which acts to suppress precipitation. Depending on the...

Detecting human influence on extreme temperatures in China
This study compares observed and model-simulated spatiotemporal patterns of changes in Chinese extreme temperatures during 1961–2007 using an optimal detection method. Four extreme indices, namely...

Regional climate impacts of a biofuels policy projection
The potential for regional climate change arising from adoption of policies to increase production of biofuel feedstock is explored using a regional climate model. Two simulations are performed using...

Radiosondes Over the Ice-free Arctic Ocean in 2010
We investigated the impact of radiosonde data from the ice-free Arctic Ocean obtained by the Japanese R/V Mirai during a cruise in the fall of 2010 on the AFES-LETKF experimental ensemble reanalysis...
