UPDATE: December 2022's global average atmospheric carbon dioxide (CO₂) was about 420 parts per million. This is a roughly 50% increase since 1750 mainly due to human activities, such as burning fossil fuels and land-use change. climate.nasa.gov/vital-signs/ca…
Why is sea level rising? Global sea levels are rising as a result of human-caused global warming, with recent rates being unprecedented over the past 2,500-plus years. @NASAJPL’s Ben Hamlington explains how our warming planet is causing sea levels to rise. sealevel.nasa.gov/understanding-…
Emissions of greenhouse gases like carbon dioxide from burning fossil fuels drive rising global temperatures. Researchers at @NASA monitor different drivers of climate, like volcanic eruptions and Sun's output and confirmed: The current warming is the result of human activities.
2022 was effectively tied for the 5th warmest year on record, according to @NASA analysis. 🌏🌡@NOAAaa’s record indicates 2022 is the 6th warmest. The past 9 years are the warmest years since at least 1880go.nasa.gov/3VZBM9aZ2H
Together with @NOAA, we're releasing our annual assessments of global temperatures and highlighting the major climate trends of 2022 during a live media briefing. When: Jan. 12 at 11am ET (1600 UTC). go.nasa.gov/3XpcIcC
While cold air was sweeping through the U.S., there was extreme warmth in northeastern Canada, eastern and western Russia, and the Arctic.
Climate change is a long-term global trend. A single cold snap doesn’t cancel out decades of warming all around the globe.
A severe cold snap set new all-time cold records in the U.S. How can that happen if Earth is warming?
It’s all about context: In the past year, there were 272 all-time warm temps, and just 62 record-cold temps.
In a stable climate, record highs and lows should be about equal.
Emissions from the last 5 years of California wildfires are more than 5x greater than the emissions from the previous 4 decades, combined. The 2020 fire year—with the most megafires in California history—had 15 times the annual average emissions that occurred during 1984–2015.
Climate change is making wildfires more frequent & longer-lasting, as shown by California’s Washburn fire in July 2022. Land managers & scientists use @NASA satellite data to track these increasingly common events & to better understand their patterns. climate.nasa.gov/news/3244/trac…
UPDATE: November's global average atmospheric carbon dioxide (CO₂) was about 420 parts per million. This is a roughly 50% increase since 1750 due to human activities, such as burning fossil fuels and land-use change. climate.nasa.gov/vital-signs/ca…
Just because it's cold for a day, a week, or a season, it doesn't mean global warming is over. All months have been warming since recordkeeping began in 1880, including December. The main cause: human activities. Stay tuned next month for the Dec. 2022 data point.
Did you know that >70% of human-caused carbon dioxide (CO₂) emissions come from cities?
On this day last year, @NASA captured elevated concentrations over Baton Rouge.
#OCO3 returns these "carbon domes" for urban areas worldwide—even on special occasions. #WinterSolstice
UPDATE: With a continuing La Niña, November 2022 was tied for the 12th-warmest November globally since modern recordkeeping began in 1880, measuring at 0.73°C (1.31°F) above the 1951-1980 baseline average: data.giss.nasa.gov/gistemp/
Congrats to the SWOT team! 💫 🌎
SWOT lifted off today at 3:46am PT atop @SpaceXeX rocket from Vandenberg Space Force Base. Led b@NASASA an@CNESES, this mission will provide high-definition data on the salt- and fresh water on Earth’s surfacego.nasa.gov/3uS3zgJWJA
We have liftoff! Once in orbit, #SWOT will return freshwater and ocean data that'll help researchers address some of the most pressing climate questions of our time and help communities prepare for a warming world. Watch the launch replay ⬇️ #TrackingWorldWatertwitter.com/NASAJPL/status…
We're now targeting no earlier than 6:46am ET (1146 UTC) on Friday, Dec. 16, for launch of the Surface Water and Ocean Topography mission. The satellite is healthy & the forecast remains favorable for liftoff on Friday morning. Follow blogs.nasa.gov/swot/ for mission updates. twitter.com/NASA/status/16…
Methane from the waste sector makes up about 20% of human-caused methane emissions. A new project from a nonprofit group, Carbon Mapper, will use @NASA instruments and data to measure emissions from landfills around the globe. Full story ⬇️ climate.nasa.gov/news/3241/nasa…
Methane is the second-most important greenhouse gas contributing to climate change. But what do those human-caused emissions look like across the U.S.? This @NASAViz video shows them in the year 2012, consistent with those reported by @EPA ⬇️ Learn more: climate.nasa.gov/climate_resour…
Why is #TrackingWorldWater important?
The Surface Water and Ocean Topography (SWOT) satellite will help communities monitor and plan for changing water resources as well as the effects of sea level rise today at noon PT (3pm ET) to learn more. youtu.be/-gM1KyJqLa0
NASA scientists are at #AGU22 this week, discussing topics ranging from sea level change to exploring oceans on other worlds to the #Artemis I mission.

What questions do you have about #TrackingWorldWater?
The SWOT satellite will survey water on more than 90% of Earth’s surface, measuring the height of water in lakes, rivers, reservoirs, and the ocean. Drop your questions in the comments below! ⬇️
See you later, SWOT! 👋
The Surface Water and Ocean Topography satellite has been encapsulated in a payload fairing, which will be placed on a@SpaceXX Falcon 9 rocket. It's scheduled for launch on Dec. 15 at 3:46 a.m. PT from Vandenberg Space Force Base.go.nasa.gov/3W4vUMbuR

SWOT, launching Dec. 15, will survey nearly all water on Earth’s surface for the 1st time. It will measure the height of the world’s ocean, rivers, & lakes, helping scientists track how fresh & saltwater bodies change over time. Here are 5 things to know. sealevel.nasa.gov/news/246/5-thi…
Earth has about 370,000,000,000,000,000,000 (quintillion) gallons of water, with some sources easier to access and use than others. The water budget tells us where that water is – key information that helps us better plan for the future.
Are wildfires getting worse? Unfortunately, yes. Climate change has led to wildfires increasing in intensity, severity, size, and duration. @NASAClimate expert Liz Hoy explains how and why we're studying these events from the ground, air, and space: nasa.gov/fires
"Water is my happy place."
Meet Cedric David, a freshwater scientist who will use data from the international Surface Water and Ocean Topography satellite (SWOT). SWOT will track water on more than 90% of Earth's surface — and it launches next week! #TrackingWorldWater
We are all connected by water. As we get closer to launching SWOT (now Dec. 15), we’re focusing on #TrackingWorldWater and want to hear from you! Share a photo, video, or questions about the mission. Here’s how (deadline: today) ⬇️ climate.nasa.gov/swot-launch/
Explosive volcanic eruptions that reach the stratosphere (above 33,000 ft, or 10,000 meters) have a cooling effect. Mt. Pinatubo’s enormous eruption in 1991 cooled the atmosphere by 0.7 to 0.9° F (0.4 to 0.5 °C) and made 1992 and 1993 the coolest years in the past 35 years.
Volcanoes emit CO₂, but far less than humans do. For example, according to @USGS, the 1980 eruption of Mt. St. Helens pumped out 10 million tons of CO₂ in just 9 hours. Sounds like a lot, right?
How long would it take for humans to emit that much CO₂? Only 2.5 hours 🚗
#ICYMI, Mauna Loa, the world’s largest active volcano, is erupting after a 38-year pause! 🌋
This animation shows a plume of sulfur dioxide (SO₂) coming from the volcano and traveling across the Pacific Ocean over the following 3 days.

The Sacramento Valley is normally California’s largest rice-growing region. But 2022 has been anything but normal. Due to drought and water shortages, growers could plant only half as much of the grain as usual, causing idle fields to turn brown: climate.nasa.gov/images-of-chan…
Climate change likely played a role in this storm. The lake's water was several degrees warmer than average, which allowed the winds to pick up more water vapor - and more snow to fall downwind. Some areas in New York got more than 75 inches (1.9 meters) of snow!
Did you know New York recently had a major “lake effect” snowstorm? The view from space helps us see how this kind of storm happens. Cold air passes above unfrozen lakes and picks up moisture, which falls as snow on the downwind side of the lake.
