White House Unveils Landmark Fuel Economy and Emissions Standards
September 17, 2009 06:49 AM - Nick Chambers, Matter Network

Today the Obama Administration released a 1,200 page document of proposed regulation changes that will drastically alter the fuel economy and emissions standards that auto manufacturers are required to meet in the US. Although it could be an incredibly contentious topic, it seems that so far the proposal has gained wide support from all sides of the spectrum including environmental organizations and industry lobby groups.

The $150 Space Camera: MIT Students Beat NASA On Beer-Money Budget
September 15, 2009 11:14 AM - WIRED

Two MIT students put together a low-budget rig to fly a camera high enough to photograph the curvature of the Earth. Instead of rockets, boosters and expensive control systems, they filled a weather balloon with helium and hung a styrofoam beer cooler underneath to carry a cheap Canon A470 compact camera.

Pop the head off a new genetically engineered dandelion and white sap oozes for minutes, allowing scientists to gather five times more latex than from the average dandelion.

Sea Levels Rose as Much as Two Feet This Summer in U.S. East

Sea levels rose as much as 2 feet (60 centimeters) higher than predicted this summer along the U.S. East Coast, surprising scientists who forecast such periodic fluctuations. The immediate cause of the unexpected rise has now been solved, U.S. officials say in a new report (hint: it wasn't global warming). But the underlying reason remains a mystery.

New Carbon Dioxide Data Helps Unlock The Secrets Of Antarctic Formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Summer Temperatures Lower Than Normal Over Most of US

Global warming doesn’t necessarily mean that temperatures are rising every year, everywhere. Superimposed on global trends are local and regional climate effects that may differ from global trends. For example, the average June-August 2009 summer temperature for the contiguous United States was below average – the 34th coolest on record, according to a preliminary analysis by NOAA’s National Climatic Data Center in Asheville, N.C. August was also below the long-term average. The analysis is based on records dating back to 1895.

Another Factor that Impacts our Climate
September 13, 2009 11:09 AM - R. Greenway, ENN

UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere. "It's like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.
