(Phys.org) -- Researchers at the SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard.

LONDON (Reuters) - The collapse of an ice sheet in Antarctica up to 14,650 years ago might have caused sea levels to rise between 14 and 18 meters (46-60 feet), a study showed on Wednesday, data which could help make more accurate climate change predictions. The melting of polar ice could contribute to long-term sea level rise, threatening the lives of millions, scientists say.

The Advances section of Scientific American 's March issue discusses how reducing soot emissions could be a quick, if temporary, fix for global warming; explains why cramming for tests doesn't work; and examines physicists' latest efforts to make an object disappear.

101010: That's the number 42 represented in binary, which is the mathematical way today's binary computers see every single piece of information flowing through them, whether it's a stock price, the latest Adele track, or a calculation to generate an MRI of a tumor. But now IBM believes it's made progress in developing quantum computers, which don't use binary coding. It is not overstating the matter to say this really may be the ultimate answer in computing machines

Imagine a planet where jellyfish rule the seas, giant rodents roam the mountains and swarms of insects blur everything in sight. It may sound far-fetched, but enough global warming is likely to change the distribution of wildlife on Earth. While species that are under threat, such as the polar bear , seem to get all the attention, others are beginning to thrive like never before.

For more than 50 years fossil fuels and fertilizers have been the key ingredients in much greater global food production and distribution. The food-energy relationship has been a good one, but it is now entering a new era. Food production is rising sharply, requiring more carbon-based fuels and nitrogen-based fertilizers, both of which exacerbate global warming, river and ocean pollution, and a host of other ills

Environmentalism, like politics in general, is depressingly polarized these days. On one side, alarmists like the activist Bill McKibben , climatologist James Hansen and blogger Joe Romm warn that if we don’t cut way back on fossil fuels now! civilization may collapse.

When the world talks climate change --as is currently under way in Durban, South Africa--the main issue is carbon dioxide emissions. CO2 is emanating from the negotiators' mouths and the power plants and cars of their home countries--and that simple molecule is responsible for the bulk of global warming to date. [More]
