This weekend, hundreds of thousands of people will take to the streets for the People’s Climate March, part of the biggest global protest ever to highlight the issue of climate change.

The march will take place in New York on September 21st, ahead of a major United Nations summit that is bringing together government leaders from around the globe to discuss this global emergency. Satellite marches will also take place in a variety of other locations around the world (see http://peoplesclimate.org/global/ for more details).

"We don’t know of any explanation that fits as well as methane," said lead study author Adam Skarke, a geologist at Mississippi State University in Mississippi State.

Scientists from the University of Stockholm have detected gigantic methane plumes escaping from the sea floor of the Laptev continental slope. It is believed that this is due to the melting of methane hydrates that have been frozen on the floor of the ocean. They are now melting and releasing the gas because the Arctic Ocean, along with the rest of the arctic, is warming rapidly.

Mass extinctions have happened periodically throughout Earth’s history for a variety of different reasons, with the usual culprits being either asteroid hits or climate change. The Eocene extinction was originally thought to have been caused by climate induced issues, but recent evidence has suggested that the changes in the weather occurred due to a meteor strike, now believed to be the one that created the Popigai crater in Siberia. The resulting "impact winter" was caused by tiny particles blanketing the Earth and reflecting the sun’s heat, creating a global temperature drop that wiped out most of the Earth’s species.
