Why it matters: The research bolsters confidence in NASA's data set, which climate change doubters have been trying to poke holes in for years, in part because it tends to find greater Arctic warming than NOAA. The study also signals how global observations might be conducted in the future.

Plastics are "potentially everywhere"
What's new: Tiny plastic pieces from broken down bags and packaging are now being detected in another element: the air. These microplastics are being deposited onto an isolated, pristine site in the French Pyrenees at an altitude of about 4,600 feet, per a new study. There's also been a sharp uptick in plastic pollution in the ocean since the late 1950s, according to another study published this week.
Earth had a top 3 warmest March on record, climate agencies find
March may have been unusually cold in parts of the U.S., but globally, average temperatures ticked upward to rank as one of the top 3 warmest Marches on record, new data from climate groups in Europe, Japan and the U.S. shows.
Why it matters: The new data shows that global average temperatures during 2019 are on track to make it another top 5 warmest year, should these trends continue. An El Niño event, featuring unusually warm water in the tropical Pacific Ocean along with an increase in shower and thunderstorm activity near the equator, is helping to add additional heat to the atmosphere.
