Thanks to the global oceans, Earth's surface temperature doesn't react instantly to the full impact of a climate disturbance. That delayed reaction has pros and cons.

Earth's surface temperature has risen about 2 degrees Fahrenheit since the start of the NOAA record in 1850. It may seem like a small change, but it's a tremendous increase in stored heat.

The U.S. tornado season to date has been very active. Our guest blogger explains how the lingering influence of La Niña might have played a role.

In the past 60 years, carbon dioxide in the atmosphere has increased 100-200 times faster than it did during the end of the last ice age.

Wildfire smoke can cause air pollution in locations thousands of miles downwind. Health experts need to know what's in the smoke people are breathing—especially smoke from fires that burn into urban areas and ignite synthetic materials.

Present since the last ice age, most of the world's glaciers are now shrinking or disappearing altogether as the climate gets warmer.

The tropical Pacific is ENSO-neutral. Our blogger covers what that means and what forecasters expect for the rest of the year.

What’s ahead for May, as we draw closer to the start of summer? Here’s what NOAA’s Climate Prediction Center (CPC) expects to occur during the month.

Many people will say “climate is the average of weather.” That’s not wrong, but it’s not a complete explanation.

Antarctic sea ice likely reached its annual minimum extent on March 1, 2025. The 2025 summer minimum extent is statistically tied with 2022 and 2024 for second-lowest in the 47-year satellite record.
