Animals and stars both emit heat. An exchange of ideas between two scientists in different fields has led to the recognition that software used to find stars and galaxies in space can be used to seek out thermal footprints and the animals that produce them. A report on findings presented at the European Week of Astronomy and Space Science.
In a TV interview, EPA Director Scott Pruitt says humans have flourished before in warm periods, and it's "arrogant for us to say that we know what [the ideal surface temperature] should be in 2100." Washington Post story is here.

Permafrost is ground that remains frozen year after year. This article in the New York Times predicts that Alaska's permafrost could be gone by 2050. Bloomberg reports that he thawing permafrost has buckled segments of the Alaska Highway, the key artery connecting the state with Canada and the northwestern U.S.
The Bulletin of the Atomic Scientists, which operates a symbolic Doomsday clock, today moved its minute hand a half-minute closer to the final hour. It had been at three minutes before the hour; now it is at two-and-a-half minutes before the hour. In a New York Times op-ed article, two scientists involved in the decision commented, "Never before has the Bulletin decided to advance the clock largely because of the statements of a single person. But when that person is the new president of the United States, his words matter."
The National Oceanic and Atmospheric Administration (NOAA) today released a beautiful new set of images of Earth, culled from its GOES-16 satellite. Although the images are gorgeous, the real achievement of GOES-16 satellite is its sophisticated forecasting, enabling scientist to better predict severe weather on Earth.
Here's a Washington Post article detailing the dangers posed to the environment by improperly recycled electronic devices. The article notes that health concerns for communities near such burn/recycle areas include infertility, childhood development problems, impaired lung function, liver and kidney damage, inheritable genetic damage and mental health problems
The IUCN (International Union for Conservation of Nature and Natural Resources) released a new update to its Red List of Threatened Species. The update includes the first assessments of various crops essential to food security, and includes the information that the global giraffe population has plummeted by 40% in the last 30 years.
“Many species are slipping away before we can even describe them,” says IUCN Director General Inger Andersen. “This IUCN Red List update shows that the scale of the global extinction crisis may be even greater than we thought. Governments gathered at the UN biodiversity summit in Cancun have the immense responsibility to step up their efforts to protect our planet’s biodiversity – not just for its own sake but for human imperatives such as food security and sustainable development.”
