Using a 13-foot pencil-shaped robot that swam under the grounding line where ice first juts over the sea, scientists saw a shimmery critical point in Thwaites’ chaotic breakup, “where it’s melting so quickly there, there’s just material streaming out of the glacier.”

As the price of natural gas rises, it’s prompting some consumer and environmental advocates to call for homes to go all-electric.

It’s been another wild week on the nature beat. The United Nations’ biodiversity conference kicked off Tuesday in Montreal with the UN Secretary-General calling humanity a “weapon of mass extinction.” Nowhere to go but up from there.

It could have been worse, UN Executive Secretary for Climate Simon Stiell said in a seaside interview with The Associated Press. The talks did achieve the historic creation of a fund for poor nations that are victims of climate disasters, he said.

The president’s brief attendance at the United Nations climate conference, known as COP27, was largely a victory lap as he emphasized new spending on clean energy initiatives that will “change the paradigm” for the United States and the rest of the world.

Of the three main types of heat-trapping greenhouse gases — carbon dioxide, methane and nitrous oxide — the biggest jump from 2020 to 2021 was in methane, whose concentrations in the air came in with the biggest year-on-year increase since regular measurements began four decades ago, WMO said.
