During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well.
Superstorm Headed to the Northeast!
Hurricane Sandy is now headed north, and is expected to hit the northeast coast of the US sometime on Tuesday-Wednesday, just in time for Halloween. Models show that the storm is likely to interact with a strong cold front headed towards the northeast from the west, leading to intensification.
Information on the storm and storm track is available from the NOAA Hurricane Center and Wunderground.
