Sealevelgate Imagine this. In its latest report, the IPCC has predicted up to 3 meters of sea level rise by the end of this century. But “climate sceptics” websites were quick to reveal a few problems (or “tricks”, as they called it). First, although the temperature scenarios of IPCC project a maximum warming of 6.4 ºC (Table [...]..

More on sun-climate relations Four new papers discuss the relatiosnhip between solar activity and climate: one by Judith Lean (2010) in WIREs Climate Change, a GRL paper by Calogovic et al.

Arctic Methane on the Move? Methane is like the radical wing of the carbon cycle, in today’s atmosphere a stronger greenhouse gas per molecule than CO2, and an atmospheric concentration that can change more quickly than CO2 can. There has been a lot of press coverage of a new paper in Science this week called “Extensive methane venting to [...]..

Readers Respond on "A Path to Sustainable Energy by 2030" Winds of Change I found it surprising that in “ A Path to Sustainable Energy by 2030 ,” Mark Z. Jacobson and Mark A. Delucchi do not mention the effects of the suggested energy sources on climate. The authors propose to absorb about six terawatts of energy from about 60 terawatts available in the wind, or about 10 percent of its total energy. Because the winds, at least near the U.S., usually flow around highs or lows, where the spe..

IPCC Errors Prompt Review by International Science Academies African crop yields wither, along with the Amazon rainforest; Himalayan glaciers disappear by 2035. These are the erroneous predictions ascribed to the most recent report from the U.N. Intergovernmental Panel on Climate Change (IPCC)--a document reviewed by some 2,500 scientists and other experts as well as vetted by more than 190 countries. So does the fact that a few errors crept into a more than 3,000 page report merit a revision of IPCC p..

End-of-Days Danger I don’t know how many e-mails I have received from children who are terrified that 2012 will somehow involve the end of life as we know it, all because of an unfounded fringe religious prophecy that has received mass-market exposure with the release of a recent Hollywood movie. I have tried to reassure those children (and not a few adults) that this date represents nothing more cosmically special than the year of the next presidential elect..

More maize ethanol may boost greenhouse gas emissions Mandated increases in the production of maize-derived ethanol will lead to land-use changes that boost carbon dioxide emissions enough to make the fuel a worse environmental option than burning gasoline, according to a new analysis...

Aquatic 'dead zones' contributing to climate change The increased frequency and intensity of oxygen-deprived "dead zones" along the world's coasts can negatively impact environmental conditions in far more than local waters. Scientists explain that the increased amount of nitrous oxide produced in hypoxic waters can elevate concentrations in the atmosphere, further exacerbating the impacts of global warming and contributing to ozone "holes" that increase our exposure to harmful UV radiation...

New study debunks myths about vulnerability of Amazon rain forests to drought A new study has concluded that Amazon rain forests were remarkably unaffected in the face of once-in-a-century drought in 2005, neither dying nor thriving, contrary to a previously published report and claims by the Intergovernmental Panel on Climate Change...

Production of chemicals from wood waste made more environmentally-friendly and cheaper Researchers have discovered that the bacterium Cupriavidus basilensis breaks down harmful by-products which are produced when sugars are released from wood. They also managed to incorporate the degradation process in bacteria which are in common industrial use. This breakthrough does away with the need to resort to costly and environmentally unfriendly methods for removing by-products, thereby boosting the appeal of waste wood as a sustainable re..

Scientists solve puzzle of chickens that are half male and half female A puzzle that has baffled scientists for centuries -- why some birds appear to be male on one side of the body and female on the other -- has been solved by researchers. The research, which involved studying rare naturally occurring chickens with white (male) plumage on one side and brown (female) plumage on the other, sheds new light on the sexual development of birds...

A Propane-Powered Lawnmower Cuts Cleaner Barbecue-grill gas creates a better mower Propane fuels your camp stove and patio grill because it burns efficiently and is easy to store safely. Now the same canisters are making lawn mowers more eco- and user-friendly, too. The propane-powered Eco Mower spews 26 percent less greenhouse gases and 60 percent less carbon monoxide than a gasoline model, plus you can replace its fuel conveniently and inexpensively. Twist a store-bought 16-ounce can ..

Antarctic Collision Snaps Rhode-Island-Sized Iceberg Off Glacier Could deprive regions of the globe of oxygen This month, an iceberg roughly the size of Luxembourg slammed into an Antarctic glacier known as the Mertz Ice Tongue. Then, last week, a Rhode Island-sized section of the Mertz Ice Tongue finally snapped off. Some scientists are excited about the new research opportunities this ice reconfiguration opens up, but others worry that the newly freed ice will significantly threaten life in the ocean. For t..

A Quarter-Century After the Worst Toxic-Gas Leak in History, Questions Linger Eleven-year-old Salu Raikwar, born with six fingers on both hands, walks near the Union Carbide pesticide plant in Bhopal, India. In December 1984 an estimated 27 tons of toxic methyl isocyanate (MIC) gas leaked from the plant and into the environment. The disaster resulted in the death of more than 6,000 people. Now, with the passing of the 25th anniversary of the disaster, anecdotal evidence and reports not publicly available suggest a long-l..

Bacteria Colony May Grow Nanowires to Create Giant Living Biogeobattery Earth lacks a living neural network that connects all living things, as seen in Avatar's Pandora. But apparently some bacteria at least grow their own tendrils or nanowires to form a giant natural battery, Danish researchers report in this week's issue of the journal Nature. Scientists have known that bacteria can create electricity when mixed with mud and seawater, and have even built microbial fuel cells around the little buggers. Now they hav..
