We summarize the week's scientific breakthroughs every Thursday.

Water vapor slowed recent global warming trend
A decline in stratospheric water vapor has slowed Earth’s surface warming slightly in recent years.

Dinosaurs, in living color
Researchers find microscopic structures in some fossils that may have held pigments.

Indian climatologist disputes charges over Himalayan projection
London’s Sunday Mail reported that it had reached the author of a chapter in a purportedly authoritative 2007 climate-change assessment and learned that this scientist – Murari Lal – deliberately used unsubstantiated sources for conclusions about the rate of glacier melting in the Himalayas. Lal doesn’t dispute that mistakes were made – ones that likely exaggerated projections of glacier melting. But he does challenge the newspaper’s charge that those mistakes were politically motivated.

Algae as biofuel still rough around the edges
Sources of nutrients, carbon dioxide can make or break this potential renewable fuel heavyweight
- Climate
IPCC’s Himalayan glacier ‘mistake’ not an accident
A London newspaper reports today that the unsubstantiated Himalayan-glacier melt figures contained in a supposedly authoritative 2007 report on climate warming were used intentionally, despite the report’s lead author knowing there were no data to back them up.

Tsunamis could telegraph their imminent arrival
Telecommunication cables could give early warnings of giant waves.

Feds propose banning giant snakes
Today, the U.S. Fish & Wildlife Service announced plans to ban the importation and interstate transport of nine species of giant snakes. It’s a good idea, but a little like closing the barn door after the horse — or in this case, the pythons and anacondas — got loose.
- Humans
Minor air traffic delays add up to big costs
On average, the economic impact of late flights exceeds that of hurricanes
- Climate
IPCC admits Himalayan glacier error
The Intergovernmental Panel on Climate Change acknowledged today that it had erred in projecting the rate and impacts of retreating Himalayan glaciers in a 2007 report.

BPA is regulated . . . sort of
Food and Drug Administration officials “say they are powerless to regulate BPA” because of a quirk in their rules, according to a story that ran Sunday in the Milwaukee Journal Sentinel. It comes from a reporter who has made an award-winning habit of documenting the politics that have helped make the hormone-mimicking bisphenol-A a chemical of choice for many manufacturers.

How better weather models can save peanut farmers money
Better weather forecasts could help farmers avoid unnecessary pesticide spraying.
- Climate
IPCC relied on unvetted Himalaya melt figure
British newspapers have uncovered what appears to be an embarrassing fact-checking omission by the Intergovernmental Panel on Climate Change, or IPCC. It regards the degree of glacial melting in the Himalayas — information that said parts of the area could be icefree a quarter century from now.
