With glaciers melting due to rising temperatures, ocean levels are rising too, and this worries coastal cities. With a 520-mile-long coastline, lined with everything from public beaches to skyscrapers, New York City is facing threats posed by rising seas and climate change.

The Antarctic Ice Sheet may be a major source of the potent greenhouse gas methane. Old organic matter frozen beneath it may have been converted to methane by micro-organisms living there under oxygen-deprived conditions, and as the ice melts, the methane will be released.
Planetary scientist Slawek Tulaczyk says, "It is easy to forget that before 35 million years ago, when the current period of Antarctic glaciations started, this continent was teeming with life. Some of the organic material produced by this life became trapped in sediments, which then were cut off from the rest of the world when the ice sheet grew. Our modeling shows that over millions of years, microbes may have turned this old organic carbon into methane."

If we can’t get human beings to stop contributing to climate change, maybe we need to re-eingineer humans. Many contactees (NOTE: Subscribers can still listen to this interview) think "the Grays" are biological machines–maybe we need to be that too.

Nearly one-tenth of hemisphere’s mammals are unlikely to outrun climate change.
A safe haven could be out of reach for 9% of the Western Hemisphere’s mammals, and as much as 40% in certain regions, because the animals just won’t move swiftly enough to outpace climate change.
For the past decade scientists have outlined new areas suitable for mammals likely to be displaced as climate change first makes their current habitat inhospitable, then unlivable. For the first time a new study considers whether mammals will actually be able to move to those new areas before they are overrun by climate change. read more
