New study finds CO2 today enough to raise sea level by 20 metres

An international team of scientists, from Texas A&M University, the University of Southampton and the Swiss University ETH Zürich, led by the University of St Andrews, published their findings in the study, Atmospheric CO2 over the Past 66 Million Years from Marine Archives. The international team pulled together data collected over the last 15 years using high-tech laboratory techniques.  The combined data spans the…

Any reduction in emissions means shorter open-water periods

A new study be the University of Manitoba, finds that for every degree of global warming, the open water period in the Arctic will increase by roughly one month. The study, Arctic open-water periods are projected to lengthen dramatically by 2100 – published in the Nature journal Communications Earth & Environment, notes: The shrinking of Arctic-wide…

The Doomsday Glaciers in East Antarctica | Earth Under Water

A new study suggests that the East Antarctica Ice Sheet in the Wilkes Basin may have completely disappeared around 400,000 years ago. Currently the Wilkes Basin is only hold back by the Cook, Mertz, and the Ninnis glacier – the Cook Glacier shelf has already collapsed. There is also the Totten Glacier farther to the…
