These results come from the SABER instrument onboard NASA’s TIMED satellite. SABER monitors infrared emissions from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air 100 to 300 kilometers above our planet’s surface. By measuring the infrared glow of these molecules, SABER can assess the thermal state of gas at the very top of the atmosphere–a layer researchers call “the thermosphere.”
When the thermosphere cools, it shrinks, literally decreasing the radius of Earth’s atmosphere. This shrinkage decreases aerodynamic drag on satellites in low-Earth orbit, extending their lifetimes. That’s the good news. The bad news is, it also delays the natural decay of space junk, resulting in a more cluttered environment around Earth.

Foreign markets are lining up to purchase American coal by widening amounts as U.S. coal consumption reaches its lowest level in more than three decades.
Power plants’ consumption of coal dropped to 298 million short tons in the first half of 2018, a sharp fall from 312 million in the same period last year, according to a Thomson Reuters report.
This marks the lowest level of consumption since 1983 and a reflection of the coal industry’s declining status as natural gas continues to grow.
Coal-fired generation diminished by 32 billion kilowatt-hours during the first six months of 2018.

Contrary to what has been announced, Cañete has not submitted the proposal to the EU member states, the German Press Agency in Brussels has learned. The idea was met with opposition by, among others, German Chancellor Angela Merkel and the German industry. Other EU countries also rejected it. Global climate policy is in crisis since US President Donald Trump quit the Paris climate agreement of 2015.
