Fuel or food? Study sees increasing competition for land, water resources
2016-03-03 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: As strategies for energy security, investment opportunities and energy policies prompt ever-growing production and consumption of biofuels like bioethanol and biodiesel, land and water that could otherwise be used for food production increasingly are used to produce crops for fuel. About 4 percent of the world's agricultural land and 3 to 4 percent of its fresh water are now used for growing biofuels, according to a new study published March 3, 2016 in the Nature journal Scientific Reports.

Study Finds Climate Change May Drive Wealth Inequality

Courthouse News Service: Rising ocean temperatures caused by climate change are driving fish populations to cooler water, and the changes will have an "inevitable and unpredictable" impact on the world's economy, according to a study by university researchers. Researchers say important fish species are relocating closer to the Earth's poles because of continued global warming and their migration could devastate certain fishing-based economies. The changes are shifting natural resources from nations near the equator and...

Extreme tornado outbreaks are on the rise, study says
2016-03-03 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: The average number tornado outbreaks that bring multiple twisters from a single weather event is on the rise in the U.S., according to new research, and the findings could change the way insurers and disaster preparedness officials respond to tornadoes. The study, published in the journal Nature Communications, also shows an increased variability in the number of tornadoes from one outbreak to another. Higher variability means that large outbreaks that result in multiple tornadoes can be more...
Study helps narrow down one reason why clouds are hard to model

PhysOrg: Airborne particles known as "aerosols" strongly impact the way clouds form and change, but accurately capturing this effect in computer climate models has proved to be notoriously difficult. A new study in the Proceedings on the National Academy of Sciences Early Edition online Feb. 26 suggests why-either the models are failing to capture in sufficient detail the processes at work in clouds, or aerosols are now so pervasive in the atmosphere thanks to modern-day pollution that their specific effects...
Extreme tornado outbreaks have become more common, says study

ScienceDaily: Most death and destruction inflicted by tornadoes in North America occurs during outbreaks--large-scale weather events that can last one to three days and span huge regions. The largest ever recorded happened in 2011. It spawned 363 tornadoes across the United States and Canada, killing more than 350 people and causing $11 billion in damage. Now, a new study shows that the average number of tornadoes in these outbreaks has risen since 1954, and that the chance of extreme outbreaks --tornado factories...
