Trump Denies, China Leads on Climate
Speaking at the United Nations General Assembly, President Trump railed against climate science and clean energy, drawing sharp rebukes from other nations, rival politicians and business leaders. Meanwhile, China for the first time ever announced a specific target for reducing its greenhouse gas emissions, by 7 to 10 percent by 2035.


Highway Reborn as Public Park
The four-lane Great Highway used to run along the Pacific Ocean on the west side of San Francisco, where it was at risk of flooding from sea level rise. Now it’s been transformed into a park where visitors can bike, walk, skate, and play next to the water.


An Extraordinary New Telescope
The new Vera C. Rubin observatory telescope in Chile features the largest camera ever built, at about the size of a small car, and will soon begin photographing the entire southern sky repeatedly for a full decade. Astronomers hope this new telescope will help advance our understanding of dark matter and reveal hard-to find interstellar objects.

Deep-diving whales use echolocation to hunt in the pitch black of the deep ocean. Research shows that plastic debris in the ocean “looks” very similar to common whale prey, like squid, when hit with these sound waves. Living on Earth’s Don Lyman reports that whales may be mistaking this plastic debris for their food.
