In 1965, the Science Advisory Committee produced a review, containing a lengthy chapter on the rising levels of CO2 in the atmosphere from the use of fossil fuels and its impact on global temperature.[read more]

NOAA has released its “State of the Climate Global Analysis” for May 2012. Here are the highlights:The combined global land and ocean average surface temperature for May 2012 was 0.66°C (1.19°F) above the 20th century average of 14.8°C (58.6°F). This is the second warmest May since records began in 1880, behind only 2010.The Northern...[read more]

Through 2010 and 2011 in particular, weather extremes seemed to dominate the headlines. Extreme drought, rainfall, flood and wind all played a role in making the period one of the most expensive in terms of damage to infrastructure. In some locations there was also significant loss of life.[read more]
