Seasonal predictions may be routine, “subseasonal” predictions are more difficult. The Madden-Julian Oscillation (MJO), a large complex of tropical thunderstorms, dominates subseasonal phenomena over the tropics. A new global atmosphere-ocean-land-sea ice coupled climate model shows an average MJO prediction skill of 30 days, placing it among the world’s best MJO prediction models.

A new study finds that El Niño events will have greater amplitude and persistence in the second half of the 21st century, leading to increased global impacts on temperature and precipitation.

For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide.

A 2021 Nature Geoscience paper argued that the Atlantic Meridional Overturning Circulation (AMOC) started slowing in the 19th century, and slowed more in the mid-20th century. But a new Nature Geoscience paper suggests that AMOC changes are still uncertain.

A first-of-its-kind guidebook tells planners how to manage and mitigate urban heat. The new book covers urban heat islands and building urban heat resilience.

Published :. April 2022. Heat is the number one weather-related killer in the United States. As average global temperatures continue to rise, the threats of both extreme heat events and chronic heat a ...

Carbon dioxide levels also recorded a big jump.

In many locations, spring snow also melts earlier, reducing summer streamflows.
