I'm really not that certain which is more frightening?

This past week an international research team led by University of Alaska-Fairbanks scientists Natalia Shakhova and Igor Semiletov released their findings from a five year study that examined the waters of the East Siberian Arctic Shelf, which covers more than 772,200 square miles (two million square kilometers) of seafloor in the Arctic Ocean. The team found that methane is leaking into the atmosphere from unstable permafrost in the Arctic Ocean faster than scientists had originally thought and could worsen global warming.

Or.........

The fact that there are people including some world leaders who still outright deny climate change is occurring, and its effects on our planet or refuse to believe that humans have been contributing to it.

Scary.
