Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Arid areas absorb unexpected amounts of atmospheric carbon
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide ...
Climatologist challenges low-end claims of Intergovernmental panel
Researchers find Europe's forests moving toward carbon sink saturation point
Coastal cities face rising risk of flood losses, study says
The world's 136 largest coastal cities could risk combined annual losses of $1 trillion (750 billion euros) from floods by 2050 unless they drastically raise their defences, a study warned Sunday.
How do you feed 9 billion people?
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
Cities affect temperatures for thousands of miles
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. In a new study that shows the extent to which human activities are influencing the atmosphere, scientists ...
Enough wind to power global energy demand, new research says
There is enough energy available in winds to meet all of the world's demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- ...
Climate change and the soil: Climate warming may not drive net losses of soil carbon from tropical forests
The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous ...
Study vindicates climate models accused of 'missing the pause'
Climate models can recreate the slowdown in global warming since 1998, as long as they correctly factor in crucial variables such as the state of the El Niño system, new research has shown.
Team finds sea level rise in western tropical Pacific anthropogenic
A new study led by Old Dominion University and the University of Colorado Boulder indicates sea levels likely will continue to rise in the tropical Pacific Ocean off the coasts of the Philippines and northeastern ...
Rewriting the history of volcanic forcing during the past 2,000 years
A team of scientists led by Michael Sigl and Joe McConnell of Nevada's Desert Research Institute (DRI) has completed the most accurate and precise reconstruction to date of historic volcanic sulfate emissions ...
Climate engineering offers little hope of mitigation
Injecting particles into the stratosphere to shade and cool the Earth will never stop climate change. This is the shocking claim made in the July issue of Nature Climate Change by an international group ...
Carbohydrates help plants survive drought
Plants that have higher levels of starch and sugars can survive droughts better than species with lower levels, say scientists.
