The Sun's average brightness varies over time, and the changes can affect global surface temperature. But long-term changes over the period of human-caused global warming are minimal.
The amount of sea ice that survives the Arctic summer has declined by 13 percent per decade since the start of the 43-year satellite record.
Global average sea level has risen 8-9 inches since 1880, and the rate is accelerating thanks to glacier and ice sheet melt.
In the past 60 years, carbon dioxide in the atmosphere has increased 100 times faster than it did during the end of the last ice age.
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.

Is there any pattern to U.S. snowfall during La Niña winters? Based on past years, our blogger tells us where you're likely to need your shovel.
Released in 2023, the Fifth National Climate Assessment (NCA5) includes an Art × Climate gallery. This work by Michele Colburn was influenced by the 2021 fire season in California.
What role could reducing the amount of sunlight reaching Earth's surface play in offsetting global warming due to greenhouse gases?
One strategy for combating climate change is to enhance natural processes and/or deploy new technologies that remove carbon dioxide from the air and ocean.
