Both greenhouse gas emissions and changes in land use and cover have modified the Earth’s climate since preindustrial times. A modelling study now shows that the impact of land-cover change on regional climate depends critically on how snow cover and rainfall change under increased greenhouse gases.
Global marine fisheries research shows how climate change is likely to impact the economics of world fisheries by affecting primary productivity, distribution and the potential yield of exploited species. Despite the gaps in understanding climate change effects on fisheries, the available information highlights the need for mitigation and adapation policies to minimize impacts.
The systematic bias in the position and strength of the 'roaring forties' that is found in climate models affects our present ability to predict carbon dioxide uptake by the Southern Ocean.
Budget cuts earlier this year to the US agency that collects and analyses energy data are worrying industry experts. Many fear that businesses and policymakers won't have vital information to make decisions regarding infrastructure, from building design to grid deployment.
Global climate models have a well-known bias in the position and strength of the Southern Hemisphere westerly winds. Research reveals that this bias increases carbon uptake by the ocean, reducing atmospheric carbon dioxide concentrations, in climate model simulations—a result that should help constrain uncertainties in climate model projections.
As the United Nations climate negotiations flounder, businesses are forging ahead with their own low-carbon standards. Have we passed a political tipping point for momentum on carbon action?
In October, the Berkeley Earth Surface Temperature project, funded in part by climate sceptics, concluded that the Earth is warming based on the most comprehensive review of the data yet. Nature Climate Change talks to the project's director, physicist Richard Muller.
