Welcome to Blog Action Day 2009! Starting early this morning in the Far East until late tonight in the Pacific Islands, more than 8,700 bloggers from 148 countries are stimulating a global conversation about many aspects of climate change. For me, the choice was easy – I write about science, so of course I’ll blog [...]

[Update: I am moving to a once-a-week blog post. Check here each Tuesday for a brand new entry of Brave Blue Words!]
The most significant anthropogenic greenhouse gas (GHG) is carbon dioxide, CO2. Comprehensive reductions in the atmospheric concentration of CO2 (expressed as “parts per million or ppm) are the only way to bring down global [...]

Summary — Most initiatives to slow global warming involve reducing carbon dioxide emissions. Little attention has been given to reducing emissions of the light-absorbing particles known as “black carbon” or the gases that form ozone–even though doing so would be easier and cheaper [...]

European scientists have discovered more than 250 plumes of methane (CH4) gas bubbles rising from the seabed of the West Spitsbergen continental margin in the Arctic, at a depth of 150 to 400 meters. The warming of Arctic currents by 1° over the last 30 years has triggered the release of methane, a potent [...]

The thermometer will hit upper nineties again today in Washington, DC., but it’s been a pretty mild summer until now – in fact, July was slightly cooler than average. That wasn’t the case up north, way up north, in Tuktoyaktuk, Northwest Territories, Canada. In this seaside town 1,500 miles north of Seattle and well within [...]
