Each month NOAA's National Climatic Data Center (NCDC) releases two assessments, one national and one global, of the previous month's climate. These reports include information on the temperature and precipitation levels experienced nationally and globally, providing useful information about these important climate variables in historical perspective. The reports also chronicle any significant weather and climate-related events that occurred during the month. This trusted source of information is used globally by industry and business, government agencies, academia, and members of the public to help inform decision making.

In a pioneering use of computed tomography (CT) scans, scientists at Woods Hole Oceanographic Institution (WHOI) have discovered that carbon dioxide (CO2)-induced global warming is in the process of killing off a major coral species in the Red Sea. As summer sea surface temperatures have remained about 1.5 degrees Celsius above ambient over the last 10 years, growth of the coral, Diploastrea heliopora, has declined by 30% and "could cease growing altogether by 2070" or sooner, they report in the July 16 issue of the journal Science.

"The warming in the Red Sea and the resultant decline in the health of this coral is a clear regional impact of global warming," said Neal E. Cantin, a WHOI postdoctoral investigator and co-lead researcher on the project. In the 1980s, he said, "the average summer [water] temperatures were below 30 degrees Celsius. In 2008 they were approaching 31 degrees."

More than half of all new electricity capacity added in the United States and Europe last year was from renewable power such as wind and solar, a body backed by the International Energy Agency and the UN reported.

Last year was also a record year for the amount of new green power added to the grid, partly a result of shifting deployment and manufacture to emerging economies including Brazil, India and China, from flagging developed countries.

With the growing trend towards environmental awareness, green printing is fast becoming a top option for businesses that need printed promotional materials. Here are the top five ways for you to make sure that your advertising and promotional campaigns don't hurt Mother Nature.

Lake District grasslands could be playing an important role in the fight against global warming.

Grasslands cover a vast area of the UK, forming the backbone of the livestock industry. However, they also play a crucial role in the global carbon cycle, storing vast amounts of carbon beneath them in their soils.
