NASA Satellite Tracks Global CO2 Emissions

This CityLab article talks about how NASA uses data from Orbiting Carbon Observatory-2 (OCO-2), a newly launched remote-sensing satellite to visually track the CO2 emissions from the past 365 days. The article states that:


"the visualization shows how though the vast majority of CO2 comes from the Northern Hemisphere's industrial centres, it doesn't stay there year-round. "


Narrated by the research meteorologist Bill Putman, the visualization is a useful reminder that greenhouse gases don't come in silos. Earlier this month, new research from Bloomberg New Energy Finance (BNEF) indicated that in 2015, CO2 emissions from the U.S. energy sector are on track to fall to their lowest levels since 1994, mostly thanks to a record number of coal plants shuttering around the country. But globally, CO2 emissions are still increasing, year after year—and regardless of where they originate, the entire planet is impacted".
