The Oil Spill and Methane Issue?

The amount of methane (which is a strong Greenhouse Gas) is what is key here and not enough methane will be leaked to make to much of a difference. You may not know this but as the planet warms up due to the Global Warming the Tundra areas that are normally frozen 12 months of the year will also release methane into the atmosphere and thereby magnifying the Global Warming.
