Giant ‘survivor’ planet found orbiting dead star

For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

WHITE HOUSE: Docs: Trump aides pushed EPA for fewer methane checks

EPA bowed to White House pressure to reduce requirements for monitoring and repairing methane leaks at facilities that push natural gas through pipelines. EPA staffers said it could “compromise” the legal underpinning of the rule.

What Trump’s Environmental Rollbacks Mean for Global Warming – The New York Times

President Trump has made dismantling federal climate policies a centerpiece of his administration. A new analysis from the Rhodium Group finds those rollbacks add up to a lot more planet-warming emissions. The Trump administration has acted to repeal or weaken…

Mercury concentrations in Yukon river fish could surpass EPA criterion by 2050

The concentration of mercury in the fish in Alaska’s Yukon River may exceed the EPA’s human health criterion by 2050 if greenhouse gas emissions that cause global warming are not constrained, according to new research.

Temperatures threaten to become unbearable

When methane-eating microbes eat ammonia instead

As a side effect of their metabolism, microorganisms living on methane can also convert ammonia. In the process, they produce nitric oxide (NO), a central molecule in the global nitrogen cycle. Scientists now discovered the enzyme that produces NO, closing an important gap in our understanding of how methanotrophs deal with rising environmental ammonia concentrations.
