The melt rate of West Antarctica’s Thwaites Glacier is an important concern for climate scientists, because this glacier alone is currently responsible for about 1% of global sea level rise. (Photo: Stuart Rankin/Flickr/cc)
A study by British and American scientists revealed that a massive sheet of ice known as the “doomsday glacier” is melting faster than experts previously believed—edging the world closer to a possible sea level rise of more than 10 feet.
Researchers at New York University and the British Antarctic Survey drilled through nearly 2,000 feet of ice in the Thwaites glacier in West Antarctica, to measure temperatures at the 75-mile wide ice sheet’s “grounding line,” where the ice meets the ocean. Continue reading →
The concept of a canary in a coal mine – a sensitive species that provides an alert to danger – originated with British miners, who carried actual canaries underground through the mid-1980s to detect the presence of deadly carbon monoxide gas. Today another bird, the Emperor Penguin, is providing a similar warning about the planetary effects of burning fossil fuels.

A landmark United Nations climate report published Wednesday details the observed and anticipated future impacts of planet-heating emissions from human activity on the world’s oceans and frozen zones—and warns of the emerging consequences for humanity, marine ecosystems, and the global environment.
Sixteen-year-old Greta Thunberg, who began the global movement in which students around the world have walked out of their classrooms on a weekly basis since last fall to demand climate action, reported Tuesday that at least 1,351 separate strikes are now scheduled to take place all over the world on Friday.

Most serious melting is occuring in West Antarctica, scientists say. East Antarctica has experienced far less melting because the bulk of its ice is above sea level. (Photo: Natalie Tapson/flckr/cc)
Scientists are expressing alarm over “utterly terrifying” new findings from NASA and the European Space Agency that Antarctica has lost about 3 trillion tons of ice since 1992, and in the past five years—as the atmospheric and ocean temperatures have continued to climb amid ongoing reliance on fossil fuels—ice losses have tripled.
This should be a wake-up call, said University of Leeds professor Andrew Shepherd, a lead author of the report. “These events and the sea-level rise they’ve triggered are an indicator of climate change and should be of concern for the governments we trust to protect our coastal cities and communities.
