2019 Was the 2nd-Hottest Year on Record

Climate Change, Anthropocene, & Associated Issues / Weather and Atmospheric Issues

2019 was the second warmest year since modern record keeping began, according to NASA and the National Oceanic and Atmospheric Administration (NOAA) climate experts. We work with NOAA to track temperatures around the world and study how they change from year to year. For decades, the overall global temperature has been increasing.

Here at NASA, we use our unique view from space – combined with airborne and ground-based measurements – to better understand our home planet. We’re also developing new ways to observe and study the Earth with long-term data records and computer analysis to better see how our planet is changing.
