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 carbon dioxide in our atmosphere today. If you've felt the surge of caffeine hitting your system, you've experienced the effects of just 400 ppm.
Image description:
Graphic looks down on a cup of coffee, with Planet Earth as the “coffee.” To the right of the coffee cup is the text “Can you tell the difference between caffeinated coffee and decaf?” Below the coffee cup is the text “If so, you have detected a concentration of 400 parts per million (ppm). There’s more than 400 ppm of carbon dioxide in Earth’s atmosphere.” It follows with bold text saying “Small amounts of powerful substances have big effects.”

These images show part of Pakistan before and after extreme monsoon rains triggered widespread flooding in August. Described as an “unprecedented climate catastrophe” by @unitednations, the floods follow a period of intense heat and drought in the country. Visit the link in our bio to learn more.
Video description: Video alternates between a "before" image from Aug. 4, 2022, and an "after" image from Aug. 28, 2022, of south-central Pakistan, as seen from space. Text at the top right says "Flooding in Pakistan," along with the dates for each image. Text directly below that says "Visit the link in our bio to learn more."

Meet Joy Hamilton, a GLOBE teacher from Shageluk, Alaska.
Joy participates in ice and snow studies from her hometown of Shageluk to help her students understand how the local rivers interact and why it is important to help scientists collect data in Arctic and sub-Arctic communities.
Read more about the Innoko River and Joy’s observations at: https://earthobservatory.nasa.gov/images/149996/living-with-floods-in-the-innoko-lowlands.

New satellite imagery shows Lake Powell’s water levels at the lowest they’ve been since 1967, dropping 98 feet (about 30 meters) in the last 5 years. The lake, which is the second-largest reservoir in the U.S., is at just 26% capacity due to an unyielding drought. Visit the link in our bio for more “Images of change.”
Video description: Video alternates between an August 2017 satellite image of Lake Powell and an August 2022 image. The words "Diminishing Lake Powell" appear at the bottom right, along with the date for each image. Lake Powell is labeled in the center.

Seas are rising, and the pace is quickening. 🌊
Sea levels around the globe have risen 10.1 centimeters (about 3.98 inches) on average, according to 30 years of satellite data. That's like covering the contiguous U.S. in about 16 feet (about 5 meters) of water. Recent rates have been unprecedented over the past 2,500-plus years.
📈 This line graph shows an overall rise in sea levels. Highs and lows each year are caused by the exchange of water – like through rain and snow – between land and sea.
🌎 The globe shows how the rate of sea level rise varies in different areas, with some parts of the ocean rising faster (shown in red and orange) than the global rate. Many of the anomalies (changes from an average) reflect long-term shifts in ocean currents and heat distribution, such as El Niño and La Niña events.
@NASA and its partner agencies have been monitoring sea levels from space for 30 years, starting with the TOPEX/Poseidon satellite that launched in 1992. Since then, five satellite missions with similar instruments have continued measuring sea level from orbit. Together, these missions provide a standardized record of ocean surface heights that is sensitive enough to detect global and regional sea level changes. 🛰

VIDEO DESCRIPTION:
The video shows an animated line graph of sea level change as seen from space. The line shows fluctuations, but overall about 10 centimeters of rise since 1992. Behind the graph, a rotating globe shows where sea levels are rising.
Dr. Robert Kennedy (associate professor of geography at Oregon State University and a researcher for @NASA’s Carbon Monitoring System) knows the importance of capturing data — like images — of our planet.
Data help scientists understand Earth’s processes and aid in monitoring changes over time. You can help scientists like Robert have a more complete picture of the planet by sharing your pictures of the land.
To do so, simply download the @globeprogram Observer app and start making observations with the "Land Cover" tool. And if you do so between now and August 26, you will take part in the NASA GLOBE Land Cover Challenge: Land Cover in a Changing Climate.

Satellite views of our #urban centers show the growth of cities over time. And with the #Landsat 50-year record of our planet, we can see what effect cities are having on our #climate.
Dr. Eric Brown de Colstoun is a research scientist @nasagoddard. Here, Eric speaks on how monitoring changes such as longer or more intense heat waves allows scientists like him to think about ways to make urban communities more sustainable. He also asks you to make measurements on the ground with the @globeprogram using the GLOBE Observer app.
By taking measurements of the land cover near you, you can help scientists have a more complete picture of the planet. And if you do so between now and August 26, you will take part in the “NASA GLOBE Land Cover Challenge: Land Cover in a Changing Climate.”

The NOAA-NASA Suomi NPP satellite captured smoke plumes from the Washburn Fire and the Oak Fire on July 24, 2022. (Orange dots are where the spacecraft measured active fires.) The 5,000-acre Washburn Fire is burning near the Mariposa Grove of Giant Sequoias.
This forest is home to over 500 mature giant sequoia trees and was officially protected by President Lincoln in 1864 before becoming part of Yosemite National Park in 1906.
The 16,700-acre Oak Fire, 12 miles west of the Washburn Fire, is largely uncontained but does not pose a direct threat to Yosemite at present. Severe, prolonged drought and dry air over the area are causing extreme fire conditions.
Video description: Video slowly zooms in on a satellite image of California and surrounding states, centering in on smoke plumes in Central California. Text from this post's caption periodically shows up in the video in chunks.

On July 19 and 20, 2022, NASA’s Aqua and Terra satellites captured these images of smoke plumes from wildfires burning in Portugal, Spain, and France. The orange dots are where the spacecraft measured active fires.
The blazes were fueled by hot, dry conditions stemming from a drier-than-normal winter and spring that has worsened drought conditions across much of Europe, according to the @europeancommission.
The heat wave rolling across western Europe produced record-high temperatures, with many regions rising above 104 degrees Fahrenheit (40 degrees Celsius).

Astronomical #summer is in full swing.
When it’s hot and humid, we sweat. But at a certain combination of heat and humidity, even sweating isn’t enough, leading to dangerous heat stress.

Globally, climate change is decreasing the number of tropical cyclones (hurricanes), new research finds. Climate models (simulations) have predicted this change for years.
The story is a little more complicated with North Atlantic hurricanes, though. Scientists have observed increased activity over the past few decades. Natural climate changes play a role, but emerging research shows human actions might too.
Visit the links in our bio to learn what else the models say, what they mean for you, and more on the latest research.
