NASA's Jet Propulsion Laboratory in Pasadena today reports new evidence of accelerating glacier melt in Antarctica.

“Observations from 11 satellite missions monitoring the Greenland and Antarctic ice sheets have revealed that the regions are losing ice six times faster than they were in the 1990s,” reads the NASA JPL announcement.

“If the current melting trend continues, the regions will be on track to match the "worst-case" scenario of the Intergovernmental Panel on Climate Change (IPCC) of an extra 6.7 inches (17 centimeters) of sea level rise by 2100.”

The two regions have lost 6.4 trillion tons of ice in three decades; unabated, this rate of melting could cause flooding that affects hundreds of millions of people by 2100.

More from the news announcement:

The findings, published online March 12 in the journal Nature from an international team of 89 polar scientists from 50 organizations, are the most comprehensive assessment to date of the changing ice sheets. The Ice Sheet Mass Balance Intercomparison Exercise team combined 26 surveys to calculate changes in the mass of the Greenland and Antarctic ice sheets between 1992 and 2018.

The assessment was supported by NASA and the European Space Agency. The surveys used measurements from satellites including NASA's Ice, Cloud, and land Elevation Satellite and the joint NASA-German Aerospace Center Gravity Recovery and Climate Experiment. Andrew Shepherd at the University of Leeds in England and Erik Ivins at NASA's Jet Propulsion Laboratory in Southern California led the study.

The team calculated that the two ice sheets together lost 81 billion tons per year in the 1990s, compared with 475 billion tons of ice per year in the 2010's - a sixfold increase.

Twenty-five experts have issued a warning about the potentially cataclysmic consequences of the rapidly shrinking insect population, reports The Guardian.

In a two-part article for Biological Conservation, the scientists wrote: “The current [insect] extinction crisis is deeply worrisome. Yet, what we know is only the tip of the iceberg.We know enough to act immediately. Solutions are now available – we must act upon them.”

From The Guardian:

The researchers said solutions were available and must be implemented immediately. These range from bigger nature reserves and a crackdown on harmful pesticides to individual action such as not mowing the lawn and leaving dead wood in gardens. They also said invertebrates must no longer be neglected by conservation efforts, which tend to focus on mammals and birds.

I was a anti-nuclear arms proliferation activist from a very young age, 10 or 11, and took it seriously, nearly getting kicked out of school and organizing classmates to attend large demonstrations. I felt like I was tackling an existential risk to the human race and most of the living things on the planet Earth (30+ years later, I think I was right), and that the grownups around me were not taking this seriously, and that this was probably the most urgent thing for me to focus on as a result.
