Update: Carbon Dioxide Concentration
August's global average concentration of atmospheric carbon dioxide (CO₂) was about 419 parts per million (ppm). This is a roughly 50% increase since 1750 primarily due to human activities, such as burning fossil fuels and land-use changes.
Update: Arctic Sea Ice Minimum Extent
Summer Arctic sea ice coverage is now shrinking at a rate of 12.6% per decade as a result of global warming.
Update: Sea Level
Global average sea level has risen over 101 milimeters (almost 4 inches) since 1993 as a result of human-caused global warming, with recent rates being unprecedented over the past 2,500-plus years.
SAGE III Sees Tonga Aerosols, Water Vapor Months After Eruption
A key part of NASA's climate observing system observed aerosols (small solid or liquid particles suspended in the air) and water vapor in the stratosphere as high as 42 to 44 kilometers (26 to 27 miles) following a noteable volcanic eruption. Aerosols and water vapor can affect Earth's climate.
Earth Science in Action: NASA Software Maps Changes in Current and Future Animal Movements
Climate change is influencing habitat conditions and migratory patterns. Leveraging NASA Earth data, a software package measures the factors that influence animal movement and maps migratory preferences.
Twitter Thread: Monthly Global Temperature Update
August 2022 was the second-warmest August globally since modern recordkeeping began in 1880, measuring at 0.95°C (1.71°F) above the 1951-1980 baseline average. The nine most recent Augusts have been the warmest on record.
Graphic: Carbon Dioxide Is Giving Earth a Jolt!
Did you know there’s about 400 parts per million (ppm) of caffeine in coffee? There's over 400 ppm of CO₂ in our atmosphere today. If you've felt the surge of caffeine hitting your system, you've experienced the effects of just 400 ppm. Visit the link above for a shareable graphic on this topic.
Images of Change: Overflowing Lake Manchar, Pakistan
Pakistan’s worst flooding in a decade from extreme monsoon rains overflowed the country's largest freshwater lake. Lake Manchar, located in the Sindh province, was one of the hardest-hit areas, with more than five times its average annual rainfall. Get the view from space at the link above.
Images of Change: Cerro Prieto Reservoir Dries Up
Persistent drought conditions in recent years have caused the water level in a Mexican reservoir to drop dangerously low. As of July 7, 2022, the reservoir was at just 0.5% of its capacity, the lowest level since it was built in the 1980s. Before-and-after images show the difference.
