A paper published today in Nature Climate Change confirms earlier studies finding that immediate and aggressive cuts in both carbon dioxide (CO2) and short-lived climate pollutants (SLCPs) are necessary to maintain global temperatures below 2°C through the end of the century.
Amid a desultory UN climate negotiation session in Warsaw this week and last—the 19th Meeting of the Parties—one strategy emerged with wide-spread support.
Scientists using sophisticated statistical methods show in a paper in Nature Geoscience that the successful phase out of chlorofluorocarbons, or CFCs, by the Montreal Protocol slowed climate change…
The gap continues to grow between emissions pledges that countries have made and the emissions levels needed by 2020 to keep global temperature rise below 2° (or 1.5°) C by 2100.
Cutting short-lived climate pollutants (SLCPs) can significantly reduce warming in vulnerable ice and snow covered areas of the world such as the Arctic and Himalayas, known as…
The Parties to the Montreal Protocol continued their steady march towards phasing down hydrofluorocarbons (HFCs) under that treaty this week in Bangkok by reconvening…
The climate threat posed by short-lived climate pollutants was just upgraded by the Intergovernmental Panel on Climate Change’s (IPCC) in its Fifth assessment published this week.
On Friday the Intergovernmental Panel on Climate Change is expected to release the first of four volumes of its fifth comprehensive assessment of scientific knowledge on climate change, known as AR5.
