Vertical ice caves in Greenland, called “moulins,” drain water from the ice to the sea — and they’re even bigger than we thought
The Centers for Disease Control and Prevention recently changed its official guidance but rolled that back because “that does not reflect our current state of knowledge,” a top CDC official said.
The loss of Thwaites Glacier could trigger the broader collapse of the West Antarctic ice sheet, which contains enough ice to eventually raise sea levels by about 10 feet.
A provocative new study finds emissions from leaks could be 25 to 40 percent higher.
The change is being driven by faster winds, which are adding more energy to the surface. That, in turn, produces faster currents and an acceleration of ocean circulation.
Scientists camped atop the floating ice shelf of Thwaites glacier in West Antarctica and drilled through 600 meters of ice to take measurements, which showed an alarming warming trend.
Continued deforestation and other fast-moving changes in the Amazon threaten to devastate wildlife and release billions of tons of carbon into the atmosphere.
The Greenland ice sheet’s losses have accelerated so fast since the 1990s it is now shedding more than seven times as much ice each year, according to 89 scientists who use satellites to study the area.
The rate of ice loss from Greenland has grown by a factor of six since the 1980s, scientists found. Half of the resulting sea level rise has occurred in just the last eight years.
Scientists find the ocean will look different in the future as a warming climate changes populations of marine microorganisms called phytoplankton.
Antarctic glaciers have been melting at an accelerating pace over the past four decades due to an influx of warm ocean water - a startling new finding.
The nation is now far off course from what the Obama administration promised under the Paris agreement, leaving a big gap for the rest of the world to make up.
The Arctic Ocean has lost 95 percent of its oldest, thickest ice. If this thinning trend continues, scientists fear an added boost to global warming.
Between 2014 and 2016, emissions remained largely flat. But that trend didn’t last. In 2017, global emissions grew 1.6 percent. The rise in 2018 could end up being twice that amount.
The central conclusion of the study - that oceans are retaining ever more energy as more heat is being trapped within Earth’s climate system each year - is in line with other studies that have drawn similar conclusions.
