Global temperatures have warmed significantly since 1880, the beginning of what scientists call the “modern record.” At this time, the coverage provided by weather stations allowed for essentially global temperature data. As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, most notably since the late 1970s. In this animation […]
Between 2000 and 2010, the worst drought ever recorded since Euro-American settlement hit the Colorado River Basin. Water levels in Lake Mead dropped to record lows. The drought not only threatened the supply of water to cities like Las Vegas, it also harmed the ecosystems and riparian areas that support countless fish, plants, and animals […]
The large and persistent external imbalances in the global economy that have developed over the past decade remain a point of concern for policymakers. Reducing these imbalances has been the major focus of consultations among G20 Finance Ministers under the G20 Framework for Strong, Sustainable and Balanced Growth and the related Mutual Assessment Process (MAP) […]
23 January 2012 (UNEP) – Industrially produced nutrient fertilizers (nitrogen, phosphorus) are essential to global food security and have been the main driver of dramatically improved agricultural yields over the last sixty years to feed a growing population. At the same time, excess nutrients from inefficient use in farming and insufficient treatment of nutrients in […]
Abstract: The “climate dice” describing the chance of an unusually warm or cool season, relative to the climatology of 1951-1980, have progressively become more “loaded” during the past 30 years, coincident with increased global warming. The most dramatic and important change of the climate dice is the appearance of a new category of extreme climate […]
Contact: Yan ZhongWei, yzw@tea.ac.cnScience in China Press24 January 2012 The Twenty-four Solar Terms are ancient Chinese terms used for about 2000 years. They describe 24 stages or timings associated with seasonal changes in phenology and agricultural activity throughout a year.

By FELICITY BARRINGER23 January 2012 To see how thoroughly the concept of ecosystem services — the economic analysis of the natural world’s intersection with human endeavors — is embedded in climate change research, check out this forecast from a group led by researchers at Duke University and the Environmental Defense Fund. It examines the future […]
After sliding considerably in the first half of 2010, the agricultural commodity price indices of the United Nations Conference on Trade and Development (UNCTAD) rose sharply, reaching peaks around February 2011 (figure II.9). Despite subsequent falls, prices remain comparatively high. The food price index averaged 268 points from January to September 2011, up 21.8 per […]
Contact: Alan Buis, 818-354-0474, Jet Propulsion Laboratory, Pasadena, California, alan.buis@jpl.nasa.gov 18 January 2012 La Niña, “the diva of drought,” is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA’s Jason-1 and […]
