In this excellent Guardian article Myles Allen of Oxford University describes and comments on reactions to a paper that he and his colleagues published in the journal Nature Geoscience. Their paper gives a new best estimate for the amount of warming that is expected due to a doubling of GHG concentrations in the atmosphere. It estimates a warming of about 1.3˚C, somewhat lower than previous estimates of 1.8°C.

Tea 2030 project, run by the UK’s Forum for the Future, has published a report identifying 19 factors likely to drive future development of value chain – and it seeks your views.

New Zealand’s temperatures are warming, and its weather patterns shifting – trends consistent with those recorded around the globe. While a reliable water source – our surrounding oceans – will protect us from the severe aridity expected in some other parts of the world, it will not insulate land-based sectors from a more intense and variable climate. Temperatures will continue to warm, and carbon dioxide concentrations will increase.

The UK Energy Research Centre (UKERC), in collaboration with the Glasgow University Media Group and Chatham House has released findings from a qualitative study of audience beliefs and behaviours in relation to climate change and energy security. 

Scientists from the American Meteorological Society (AMS) and University of California, Berkeley have demonstrated that plants and soils could release large amounts of carbon dioxide as global climate warms. This finding contrasts with the expectation that plants and soils will absorb carbon dioxide and is important because that additional carbon release from land surface could be a potent positive feedback that exacerbates climate warming.

A paper in Nature Climate Change finds that more carbon dioxide in the atmosphere and rising temperatures cause rice agriculture to release more of the potent greenhouse gas methane (CH4) for each kilogram of rice it produces.

A new study finds that Tanzania is one developing country that could actually benefit from climate change by increasing exports of corn to the U.S. and other nations. The study, published in the Review of Development Economics, shows that Tanzania has the potential to substantially increase its maize exports and take advantage of higher commodity prices with a variety of trading partners due to predicted dry and hot weather that could affect those countries' usual sources for the crop.
