The National Oceanic and Atmospheric Administration (NOAA) has reported findings of preliminary analysis from the agency's National Climatic Data Center in Asheville, North Carolina that shows global ocean surface temperatures for June broke the previous record set in 2005.

The nightmare global warming scenario which provided the plot for a Hollywood blockbuster -- the Atlantic Ocean current that keeps Europe warm shuts down and triggers rapid climate change -- has long worried scientists.

Hydrofluorocarbons, Once a Solution, Now a Problem?

Scientists say the chemicals that helped solve the last global environmental crisis -- the hole in the ozone layer -- are making the current one worse. They worked: The earth's protective shield seems to be recovering. But researchers say what's good for ozone is bad for climate change.

Mystery of Los Angeles Methane Emissions Probed
July 19, 2009 07:09 AM - New Scientist

The Los Angeles metropolitan area belches far more methane into its air than scientists had previously realized. If other megacities are equally profligate, urban methane emissions may represent a surprisingly important source of this potent greenhouse gas. Atmospheric researchers have long had good estimates of global methane emissions, but less is known about exactly where these emissions come from, particularly in urban areas.

Are Aluminum Bottles Greener than Glass?
July 18, 2009 11:33 AM - , Triple Pundit

Aluminum as a substitute for glass bottles has been inching its way into the consumer experience in the last few years, most notably in the US in the form of beer bottles from Anheuser-Busch and Iron City Beer, a popular regional brand founded in Pittsburgh. Coca-cola has also announced plans to roll out aluminum bottles in this country, though only in limited venues.

Sun's Activity Cycle Linked to Earth Climate
July 18, 2009 10:01 AM - LiveScience

When the sun's weather is most active, it can impact Earth’s climate in a way that is similar to El Niño and La Niña events, a new study suggests. The sun experiences a roughly 11-year cycle, during which the activities on its roiling surface intensify and then dissipate. (One noted sign of a highly active period is the number of sunspots dotting the solar surface). The total energy reaching Earth from the sun varies by only 0.1 percent across the solar cycle.

Are the deserts getting green?
July 17, 2009 08:17 AM - Ayisha Yahya, BBC News

It has been assumed that global warming would cause an expansion of the world's deserts, but now some scientists are predicting a contrary scenario in which water and life slowly reclaim these arid places. They think vast, dry regions like the Sahara might soon begin shrinking.
