Fast action on certain pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 3.6 degrees F. Protecting the near-term climate is central Read more…


Ever wonder how the western US has high ozone levels when the winds usually blow in off the Pacific Ocean? Did you think it was all from the cars clogging the freeways? Turns out, it is caused in part from Read more…


Biofuels – made from algae and non-food plants – are emerging as a potentially viable alternative to conventional jet fuels. Although big challenges remain, the reductions in greenhouse gas emissions could be major. Earlier this year, a Continental jet accelerated Read more…
