Steep increase in global CO2 emissions despite reductions by industrialized countries

Global emissions of carbon dioxide (CO2) – the main cause of global warming – increased by 45 % between 1990 and 2010, and reached an all-time high of 33 billion tonnes in 2010. Increased energy efficiency, nuclear energy and the growing contribution of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.
This increase took place despite emission reductions in industrialised countries during the same period. Even though different countries show widely variable emission trends, industrialised countries are likely to meet the collective Kyoto target of a 5.2 % reduction of greenhouse gas emissions by 2012 as a group, partly thanks to large emission reductions from economies in transition in the early nineties and more recent reductions due to the 2008-2009 recession. These figures were published today in the report "Long-term trend in global CO2 emissions," prepared by the European Commission's Joint Research Centre and PBL Netherlands Environmental Assessment Agency.

Deep oceans may mask global warming

Earth's deep oceans may absorb enough heat at times to flatten the rate of global warming for periods of as long as a decade--even in the midst of longer-term warming. This according to a new analysis led by scientists at the National Center for Atmospheric Research (NCAR).
The study, based on computer simulations of global climate, points to ocean layers deeper than 1,000 feet as the main location of the "missing heat" during periods such as the past decade when global air temperatures showed little trend.
The findings also suggest that several more intervals like this can be expected over the next century, even as the trend toward overall warming continues.
"We will see global warming go through hiatus periods in the future," says NCAR's Gerald Meehl, lead author of the study.

NASA's Aqua satellite sees tropical storms Nate, Lee, fires

Tropical Storm Nate is perched to make landfall in Mexico this weekend, and warnings are in effect. Nate is one of three major weather events around the Gulf of Mexico today, and NASA's Aqua satellite captured all three in one image.
Raging wildfires are occurring in Texas while the remnant clouds from Tropical Storm Lee in the northern Gulf of Mexico were also seen by Aqua.One satellite image taken by the Atmospheric Infrared Sounder instrument that flies aboard NASA's Aqua satellite captured the two tropical systems and smoke from the Texas fires on Sept. 8 at 19:05 UTC (3:05 p.m. EDT). The image shows Tropical Storm Nate was still lingering along the eastern Mexico coastline, the western edge of the remnants of Tropical Storm Lee (around a low pressure area centered over Indiana) appeared in the northern Gulf and smoke plumes from Texas wildfires.
