Many scientists, policymakers, and engaged citizens have become concerned over the possibility that manmade greenhouse gas emissions, in particular carbon dioxide (CO2), may be causing dangerous ...

Climate simulations show that interactions between particles of black carbon and convective and cloud processes in the atmosphere must be considered when assessing the full climatic effects of these ...

Researchers report that climate-related impacts to economies may slow carbon emissions at rates that can offset natural climate feedbacks that increase emissions, but at a societal cost. Rising ...

Researchers report the results of an eight-year experiment in grassland plant communities enriching carbon dioxide levels from pre-industrial to projected mid-21st century levels, and found that ...

As greenhouse gases pour into the atmosphere, global temperatures rise smoothly and predictably in response. It’s the fundamental basis of climate change, the physical law that’s been reshaping the ...
