See, that’s what the app is perfect for.

Sounds perfect Wahhhh, I don’t wanna
An aerial view of the Barents Sea, north of Norway and Russia, shows white, wispy cloud coverage over both land and ocean. Clouds are seen in the bottom left corner extending up towards the top left corner but dwindling as they rise. Clouds are also seen in the top right corner. A green colored land mass is seen along the bottom third of the image. In the dark blue ocean are vibrant swirls of teal and green phytoplankton blooms. Credit: NASAALT

Sharpening Our View of Climate Change with the Plankton, Aerosol, Cloud, ocean Ecosystem Satellite

As our planet warms, Earth’s ocean and atmosphere are changing.

Climate change has a lot of impact on the ocean, from sea level rise to marine heat waves to a loss of biodiversity. Meanwhile, greenhouse gases like carbon dioxide continue to warm our atmosphere.

NASA’s upcoming satellite, PACE, is soon to be on the case!

Set to launch on Feb. 6, 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will help us better understand the complex systems driving the global changes that come with a warming climate.

: Data visualization of global temperature anomalies progressing from 1880 to 2023 mapped onto Earth. The map uses color to represent anomalies, ranging from blue for below average temperatures, white for temperatures at baseline, and yellows ranging through oranges and reds to represent higher and higher than average temperatures. At the beginning of the time series, the map is primarily blues and whites, with a few spots of yellow, indicating that temperatures overall are below the baseline. As time progresses, the colors shift and move, with less and less blue and white and more and more yellow, then orange, and red. By 2023, the map is mostly yellow with lots of orange and red. The Arctic region, Europe, Asia, North America, central South America, and the Antarctic peninsula are all dark red, indicating the highest temperature anomalies.

Six Answers to Questions You’re Too Embarrassed to Ask about the Hottest Year on Record

You may have seen the news that 2023 was the hottest year in NASA’s record, continuing a trend of warming global temperatures. But have you ever wondered what in the world that actually means and how we know?

We talked to some of our climate scientists to get clarity on what a temperature record is, what happened in 2023, and what we can expect to happen in the future… so you don’t have to!

Line graph with monthly temperature anomalies from each year from 1880 to 2023 growing across the graph to create a stacked bell shape. The Y-axis is labeled negative 3 degrees Celsius to 3 degrees Celsius and the X-axis has each month from January to December. As time goes on, the curved lines seem to stack higher and higher, and the colors of the lines change from white and light blue to light red, and then dark red. Finally, the 2023 line stops at August, the latest month we have data for, and it’s visible that June, July, and August 2023 were all hotter than any previous respective month. Credit: NASAALT

Confirmed: Summer 2023 Hottest in NASA’s Record

All three months of summer 2023 broke records. July 2023 was the hottest month ever recorded, and the hottest July. June 2023 was the hottest June, and August 2023 was the hottest August.

NASA’s temperature record, GISTEMP, starts in 1880, when consistent, modern recordkeeping became possible. Our record uses millions of measurements of surface temperature from weather stations, ships and ocean buoys, and Antarctic research stations. Other agencies and organizations who keep similar global temperature records find the same pattern of long-term warming.

Global temperatures are rising from increased emissions of greenhouse gasses, like carbon dioxide and methane. Over the last 200 years, humans have raised atmospheric CO2 by nearly 50%, primarily through the burning of fossil fuels.

Drivers of climate change, both natural and human-caused, leave distinct fingerprints. Through observations and modeling, NASA researchers confirm that the current warming is the result of human activities, particularly increased greenhouse gas emissions.

Celebrate Earth Day with NASA

“We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.” - Apollo 8 astronaut Bill Anders

On Dec. 24, 1968, Anders snapped this iconic photo of “Earthrise” during the historic Apollo 8 mission. As he and fellow astronauts Frank Borman and Jim Lovell became the first humans to orbit the Moon, they witnessed Earth rising over the Moon’s horizon. The image helped spark the first #EarthDay on April 22, 1970.

Anders sat down with Dr. Kate Calvin, our chief scientist and senior climate advisor, to chat about the photo, and NASA’s role in studying our home.
