Nepal has made significant efforts towards low-emission development, using government tools to encourage finance flows towards climate action. However, achieving its ambitions will be difficult given current
Rising tropical sea surface temperatures alter atmospheric dynamics at heights of 16 kilometers or more.
Science-based policy is essential for guiding an environmentally sustainable approach to cellulosic biofuels.
Two new studies point to random, wind-induced circulation changes in the ocean--not global warming--as the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets.
A new survey from EcoSecurities and ClimateBiz released recently shows how large, multinational corporations are addressing their carbon footprints from within, and what strategies they're using to offset the emissions they can't avoid.
Despite the growing awareness of the nexus between climate change and migration the subject has not been explored empirically in a way that generates conclusive results.
The long-standing view of Earth
The concentration of atmospheric carbon dioxide decreased between 45 million and 25 million years ago, a trend accompanied by glaciation at the poles. Modelling results suggest when and where the ice closed in.
Carbon dioxide emissions from fossil fuels and cement manufacturing are rising faster than the worst-case scenario drawn up by the Intergovernmental Panel on Climate Change (IPCC). According to the latest worldwide carbon budget, released by the Global Carbon Project, CO2 levels rose by 3.5% a year between 2000 and 2007, compared with 2.7% as calculated by the IPCC.
Preliminary data from two Arctic cruises suggest that rising temperatures are already causing substantial amounts of methane to be released from beneath the ocean floor. But catastrophic gas leaks, like those believed to have occurred 55 million years ago, are unlikely, scientists say.
The turmoil in the financial markets could lead to severe cost-cutting by governments, but US politicians would do well to note the benefits of continued support for clean energy and climate policies. (Editorial)
