NCAR/UCAR The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global crop yields because of climate change, new research finds. The authors, from Stanford University and the National Center for Atmospheric Research, say the odds of a major production slowdown of wheat and corn, even with a warming climate, are not very high. But the risk is about 20 times more significant than it would be without global warming, and it...

Trade-offs Between Food Security And Climate Change Mitigation Addressed By New Study
2013-07-16 12:20:30

International Institute for Applied Systems Analysis Improving crop yields using sustainable methods could cut greenhouse gas emissions by as much as 12% per calorie produced according to a new study published in the journal Environmental Research Letters. At the same time, these changes could provide more food to people in need. Agriculture and land use change contributed about 1/3 of total human greenhouse gas emissions in the past decade, through crop cultivation, animal production,...

Study maps world regions where crop production rates must be increased Crop yields worldwide are not increasing quickly enough to support estimated global needs in 2050, according to a study published June 19 in the open access journal PLOS ONE by Deepak Ray and colleagues from the Institute on the Environment (IonE) at the University of Minnesota. Previous studies estimate that global agricultural production may need to increase by 60-110% to meet increasing demands and provide food...

Study uses data on 50,000 common plants and animals to predict worldwide range losses without urgent action to limit emissions Climate change could dramatically reduce the geographic ranges of thousands of common plant and animal species during this century, according to research using data made freely available online through the Global Biodiversity Information Facility (GBIF). Research published today in the journal Nature Climate Change looked at nearly 50,000 globally widespread and...

Northern Hemisphere Could Experience More Tropical Rainfall Due To Climate Change
2013-04-03 12:19:09

Brett Smith for redOrbit.com - Your Universe Online Rising global temperatures are expected to cause catastrophic change worldwide; however a team of UC Berkeley and University of Washington scientists has found that the Northern Hemisphere will see a greater shift in tropical rainfall patterns compared to the Earth´s southern half. Based on climate data and simulations, the climatologists found that rising temperatures will cause significant shifts in rainfall patterns around the...

Climate Change Effects And Adaptation Strategies For US Agriculture And Forests
2013-02-09 06:44:27

redOrbit Staff & Wire Reports - Your Universe Online Over the next 25 years, increasing temperatures will have a “generally detrimental” impact on most types of crops and livestock, according to one of two reports detailing climate change and adaptation strategies released earlier this week by the US Department of Agriculture (USDA). The report, entitled “Climate Change and Agriculture in the United States: Effects and Adaptation,” states that the effects of...

Global Agriculture Raises Greenhouse Gas Emissions
2012-10-31 09:17:51

Brett Smith for redOrbit.com - Your Universe Online Two new reports on climate change and the food supply indicate, among other things, that over 18,000 megatons of carbon dioxide are released into the atmosphere annually by agriculture and food production. Previous studies have examined the connection between agriculture and emissions, but the new report from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) performs that analysis on the entire food...

At the end of the 21st century, the temperature in the Baltic Sea will be higher and the salt content lower than at any time since 1850. If no action is taken to alleviate the effects of climate change, there may be major consequences for the marine environment. "This is the first time that anyone has taken a detailed look at how climate models and individual factors combine to affect a specific region. This makes this project unique," says Jonathan Havenhand from the Department of...

New Carbon Accounting Method To Reduce Farmers' Use Of Nitrogen Fertilizer
2012-07-18 15:06:33

Large amounts of nitrogen fertilizer lead to nitrous oxide, a greenhouse gas, in the atmosphere It's summer. For many of us, summer is a time synonymous with fresh corn, one of the major field crops produced in the United States. In 2011, corn was planted on more than 92 million acres in the U.S., helping the nation continue its trend as the world's largest exporter of the crop. Corn is a nitrogen-loving plant. To achieve desired production levels, most U.S. farmers apply synthetic...
