New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
A simplified representation of polar vortex at monthly scale was revised using a new method, and its daily association with air-sea teleconnections was analyzed to study weather impacts.
In 1972, Mikhail Ivanovich Budyko used a simple methodology to make climate predictions that remain surprisingly accurate today and that could serve as a new “business-as-usual” scenario.
CFCs and other halocarbons have long been known for causing an ozone hole over the Antarctic, but many of them are also powerful greenhouse gases.
Records of aurorae in Mesopotamia from 2,600 years ago are helping astronomers understand and predict solar activity today.
Unique observations used to examine the structure and mass balance of hurricanes’ top levels find that regions of high pressure violate the gradient wind balance.
A new study finds that rainfall rates are recovering in some cities since a 1966–1990 dry spell, but precipitation is still down overall since 1950.
Reducing emissions could avert more than 300,000 deaths per year by 2050.
How fast is Earth warming? Ocean heat content and sea level rise measurements may provide a more reliable answer than atmospheric measurements.
AGU and its funders should be held to the same standards of evidence-based scrutiny that it expects of the scientists who publish in its own journals.
