There’s a lot of news about how the methane coming out with the Gulf oil leak can cause problems in the ocean, such as depletion of oxygen.

But, in addition, methane is a powerful greenhouse gas, as EPA reminds us:

Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period

There’s a need to get on with the business of estimating how much methane from the leak is getting into the atmosphere, and its effects on climate change.
