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.

What's happening: Some of the biggest names on Wall Street are partnering with climate science groups to produce the first countrywide, property-level maps attempting to financially navigate the age of extreme weather-driven calamity.
