Update: Carbon Dioxide Concentration
December 2022's global average atmospheric carbon dioxide (CO₂) was about 420 parts per million, a roughly 50% increase since 1750. This rise is mainly due to human activities such as burning fossil fuels and land-use change.
Update: Global Temperature
Our planet has warmed about 1.1°C (about 2°F) since the preindustrial period primarily due to the burning of fossil fuels. Get the latest annual data from NASA.
Update: Ocean Warming
Average surface temperature in 2022 effectively tied with 2015 for the fifth-warmest year on record, but it was the hottest year for the ocean. Visit the link to track ocean heat content.
Twitter Thread: High and Low Temperatures in a Warming Climate
A severe December 2022 cold snap set new all-time cold records in the U.S. How can that happen if Earth is warming? A short animation explains.
Twitter Thread: Monthly Global Temperature Update
With a continuing La Niña, December 2022 was the 8th-warmest December globally since modern recordkeeping began in 1880, measuring at 0.80°C (1.44°F) above the 1951-1980 baseline average. The eight most recent Decembers have been the warmest on record.
Earth Science in Action: Tracking the West's Growing Wildfires
Climate change is making wildfires more frequent and longer-lasting, as shown by California’s recent Washburn fire. Land managers and scientists use NASA satellite data to track these increasingly common events and to better understand their patterns.
