Retreat of East Antarctic ice sheet during previous warm periods

Questions about the stability of the East Antarctic Ice Sheet are a major source of uncertainty in estimates of how much sea level will rise as the Earth continues to warm. For decades, scientists thought the East Antarctic Ice Sheet had remained stable for millions of years, but recent studies have begun to cast doubt on this idea. Now, researchers report new evidence of substantial ice loss from East Antarctica during an interglacial warm period about 400,000 years ago.

5 years after New Horizons flyby, 10 cool things about Pluto

Here are 10 of the coolest, weirdest and most unexpected findings about the Pluto system scientists have learned thanks to the New Horizons spacecraft’s flyby of the distant world in 2015.

The End Is Nigh! Revisiting The Climate Dumpster Fire

In November 2009, the Hadley Climate Research Unit at the University of East Anglia in Britain* was hacked, releasing thousands of files suggesting a covert mega-operation to propagate an “anthropogenic global warming” myth. The evidence showed that data was tampered…

Global warming and ice sheet melting: Portents of a Younger dryas-like stadial event

Global warming and ice sheet melting: Portents of a Younger dryas-like stadial event by Andrew Glikson Linear climate projections by the IPCC are difficult to reconcile with the paleoclimate evidence of stadial cooling events which closely succeeded warming peaks, including…

Guest post: Global warming edges closer to Paris Agreement 1.5C limit – Carbon Brief

The latest forecast (pdf) from the World Meteorological Organization (WMO) suggests that over the next five years there is a 24% chance of the global average temperature exceeding 1.5C above pre-industrial levels for at least one year.  While this is…

New Study Shows Oceans At Their Deepest In 250 Million Years

Sea-level rise would be a complicated topic even if it were not politicized. People often talk as though the seabed were like a bathtub, rigid and immobile, into which water either pours or does not. But it’s not; it rises…
