In major climate step, EPA proposes 1st limits on greenhouse gas emissions from power plants

The Biden administration is proposing new limits on greenhouse gas emissions from coal- and gas-fired power plants, its most ambitious effort yet to roll back planet-warming pollution from the nation's second-largest contributor to climate change.

A rule to be unveiled Thursday by the Environmental Protection Agency could force power plants to capture smokestack emissions using a technology that has long been promised but is not in widespread use in the U.S.

Long popular in Asia, floating solar catches on in US

When Joe Seaman, the city planner for the working class town of Cohoes, New York, Googled the term "floating solar," he didn't even know it was a thing. What he did know is that his tiny town needed an affordable way to get electricity and had no extra land. But looking at a map, one feature stood out, he said. "We have this 14-acre water reservoir."

Seaman soon found the reservoir could hold enough solar panels to power all the municipal buildings and streetlights, saving the city more than $500,000 each year. He had stumbled upon a form of clean energy that is steeply ramping up. Floating solar panel systems are beginning to boom in the United States after rapid growth in Asia. They're attractive not just for their clean power and lack of a land footprint, but because they also conserve water by preventing evaporation.

US agency plans deeper study of sea turtles, dredging threat

A U.S. agency has agreed to an in-depth environmental study into whether dredging a Georgia shipping channel in the spring and summer would threaten rare sea turtles nesting on nearby beaches — a review demanded by conservationists who sued to stop the project.

Georgia conservation group One Hundred Miles moved to dismiss its lawsuit against the Army Corps of Engineers after the agency announced Friday that it would voluntarily conduct the study. The group sued in December, asking a U.S. District Court judge to order the Corps to produce such a report.

Warming-stoked tides eating huge holes in Greenland glacier

Daily tides stoked with increasingly warmer water ate a hole taller than the Washington Monument at the bottom of one of Greenland's major glaciers in the last couple years, accelerating the retreat of a crucial part of the glacier, a new study found.

And scientists worry that the phenomenon isn't limited to this one glacier, raising questions about previous projections of melting rates on the world's vulnerable ice sheets.

Brazil's Amazon megaprojects threaten Lula's green ambitions

After his swearing-in ceremony on Jan. 1, Brazil's Luiz Inácio Lula da Silva walked up the ramp to the presidential palace arm in arm with Indigenous leader Raoni Metuktire, instantly recognizable by his yellow headdress and wooden lip plate.

But a major railway that would accelerate deforestation in Metuktire's ancestral land risks souring relations between the leftist leader and the chief of the Kayapó people. And it's just one of several mega-projects that activists and experts say would devastate the natural world — and seriously dent Lula's newfound image as a defender of the environment — if they proceed.
