El Niño is near peak strength. Our blogger covers current and potential future conditions in the tropical Pacific.

The wind-driven Marshall Fire erupted into the most costly wildfire in Colorado history on December 30, 2021, evolving in one hour from a grass fire into a suburban firestorm that destroyed 1,084 homes and seven commercial properties.

The Madden–Julian Oscillation (MJO) influences atmospheric circulation and deep convection over the tropical Indian Ocean and Pacific Ocean on a 30–90 day cycle. A new study finds that global warming over the past century has made the MJO more predictable.

The Atlantic Meridional Overturning Circulation (AMOC) shapes climate, weather, and marine life. A cost-effective method can estimate the AMOC at a 22.5°S, a critical location at the edges of the South Atlantic subtropical gyre.

In winter, extratropical cyclones (ETCs) bring risky weather: heavy rain and snow, and strong winds. New research will employ advanced climate models to predict how ETCs might change in the future.

Global average temperature was more than 1.5 degrees Celsius warmer than the pre-industrial average for several months in late 2023. That doesn't mean we've already breached the goals of the Paris Climate Agreement.

With 28 events, 2023 easily surpassed 2020 as the year with the most billion-dollar disasters in the U.S. The preliminary price tag is at least $92.9 billion.

Recent atmospheric patterns don't match those that typically precede a sudden stratospheric warming event. But forecasts do suggest the polar vortex might get stretched out of shape in coming weeks.

Will December's mild weather continue in January, or will winter finally rear its ugly (and cold) head?

Before 2023 officially wraps up we want to highlight some of the climate related stories, maps, and graphs that we brought you over the past year.
