Earth’s Climate System

2020-04-28T18:12:31-04:00

Global-scale observations of the Earth’s climate system (including temperature, precipitation, and other parameters) started in the mid-19th century. Modern observational techniques include both direct measurements at the ground and remote-sensing measurements from satellites. Ancient climates (paleoclimates) have been reconstructed as far back as hundreds of thousands of years by studying [...]
