"Monarch butterflies that hatch in the spring and early summer live fast and die young at only two to six weeks. But those that emerge in late summer can survive six to nine months. That’s long enough to migrate thousands of miles south for the winter and start the return north the following spring to breed."
"The Department of the Interior issued a final rule that curbs and streamlines its environmental reviews. Critics say the move is illegal."
The enforcement of environmental laws suffered a dramatic collapse during the Trump administration’s first year, several studies have found. Even the most serious violations, typically referred to the Department of Justice, are left unpursued because of DOJ staffing declines.

"A coalition of scientific, preservation and historical groups on Tuesday sued the Trump administration, arguing that the removal of information about civil rights, climate change and other topics at multiple national parks amounts to illegal censorship."
"Billions of American chestnut trees once covered the eastern United States. ... But by the 1950s, this venerable tree went functionally extinct, culled by a deadly airborne fungal blight and lethal root rot. A new study out Thursday in the journal Science provides hope for its revitalization, finding that the genetic testing of individual trees can reveal which are most likely to resist disease and grow tall, thus shortening how long it takes to plant the next, more robust, generation."
"A year ago, U.S. Health Secretary Robert F. Kennedy Jr. said he wanted to rebuild trust in federal health agencies, and vowed to employ “radical transparency” to do it. But many types of health information that steadily flowed from the government for years or decades has been delayed, deleted and in some cases stopped all together."
"Following three of the warmest years on record, as scientists reckon with climate tipping points and states and cities grapple with the escalating cost of extreme weather and more intense wildfires, the Trump administration this week is expected to formally eliminate the U.S. government’s role in controlling greenhouse gas pollution."
"Scientists have known for years that water levels are rising faster in the Chesapeake Bay region than just about anywhere else in the world — because water is only part of the problem here. The land is also sinking."
"Scientists say increasing shipping traffic is interfering with the whales’ ability to hunt and communicate. To protect the animals, conservation groups are urging the International Maritime Organization to instate mandatory measures to reduce underwater noise."
