Vegetation Carries the Signature of Recent Precipitation

by Valeriy Ivanov 3 October 202228 September 2022

Vegetation response to precipitation is important for near-term weather predictability, and researchers show that such a response can occur within a few days and last up to two months.

A Dilemma About Radiative Climate Feedback in Recent Decades

by Minghua Zhang 30 September 202228 September 2022

Given the unambiguous climate warming in recent decades, is it possible to infer radiative climate feedback from modern satellite measurements of the energy budget of the Earth?

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.

A new book explores how Earth science knowledge addresses critical global challenges including sustainable development, disaster risk reduction, and climate change.

A small coastal shipping town in Japan is devastated by an earthquake. In this photo taken from a plane, the wreckage of hundreds of buildings can be seen, and only a handful remain standing. In the center of the image, a small yacht is perched on top of one of the only remaining buildings. The town is surrounded by mountains and forests. One of the plane’s wheels is visible in the lower left corner of the image.
