NASA Announces Summer 2023 Hottest on Record

This map shows monthly temperature anomalies measure from 1880 to August 2023 measured with respect to a the baseline period 1951-1980.

Summer of 2023 was Earth's hottest since global records began in 1880, according to scientists at NASA's Goddard Institute of Space Studies (2023-09-14)

The Ocean Has a Fever

About GISS

Research at the NASA Goddard Institute for Space Studies (GISS) emphasizes a broad study of global change, which is an interdisciplinary initiative addressing natural and man-made changes in our environment that occur on various time scales — from one-time forcings such as volcanic explosions, to seasonal and annual effects such as El Niño, and on up to the millennia of ice ages — and that affect the habitability of our planet.

GISS is located at Columbia University in New York City. The institute is a laboratory in the Earth Sciences Division of NASA's Goddard Space Flight Center and is affiliated with the Columbia Climate School and School of Engineering and Applied Science.
