This trend is seen in the observational studies (blue) but not in the experimental studies (red). The numbers correspond to those in Fig. 1 and to site information given in the Supplementary Information. ABSTRACT: Warming experiments are increasingly relied on to estimate plant responses to global climate change1, 2. For experiments to provide meaningful predictions […]
By Nina Chestney; Editing by Janet Lawrence2 May 2012 LONDON (Reuters) – Plants are flowering faster than scientists predicted in response to climate change, research in the United States showed on Wednesday, which could have devastating knock-on effects for food chains and ecosystems. Global warming is having a significant impact on hundreds of plant and […]
[Declaring an end to the Big Dry seems premature, cf.: While the systematic accumulation of rainfall deficits was reversed with the heavy spring and summer rainfall of 2010, the total two-year record rainfall makes up for about one third of the total rainfall ‘missed out on’ since 1996. Additionally, the recovery peaked in autumn 2011, […]
By Brandon Keim 1 May 2012 Herbicide-resistant superweeds threaten to overgrow U.S. fields, so agriculture companies have genetically engineered a new generation of plants to withstand heavy doses of multiple, extra-toxic weed-killing chemicals. It’s a more intensive version of the same approach that made the resistant superweeds such a problem — and some scientists think […]
By David Fogarty; Editing by Ed Davies26 April 2012 SINGAPORE (Reuters) – Scientists have detected a clear change in salinity of the world’s oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming. The finding published on Friday helps refine estimates of how different […]

By Stephen Lacey 20 April 2012 Corn farmers concerned about the impact of climate change are speaking out, calling the problem “a grave threat” to the nation’s agricultural sector. Responding to the increase in severe weather — and the prospects for a “quantum jump” in such devastating events — a group of corn farmers is […]
By Marwaan Macan-Markar 19 April 2012 BANGKOK – With Vietnam’s fertile Mekong delta threatened by rising sea levels and salt water ingress, the country’s future as a major rice exporter depends critically on research underway in the Philippines. Scientists at the International Rice Research Institute (IRRI) are working with Vietnamese counterparts in the town of […]
30 March 2012 (Médecins Sans Frontières) – The annual “hunger season” seems likely to be particularly serious in the Sahel this year, and a few particular regions may face acute nutritional crises in the coming months. Doctors Without Borders/Médecins Sans Frontières (MSF) is therefore expanding its nutritional activities to address the seasonal “peak” in malnutrition […]
