Women have been working to study and understand our home planet from @NASA's very beginning. On #InternationalWomensDay2022 and all #WomensHistoryMonth, we’ll celebrate some of the women who help us see Earth more clearly.
Dr. Kate Calvin is @NASA’s Chief Scientist and Senior Climate Advisor. She connects climate science across the agency so we can better understand how our planet is changing. #IWD2022#InternationalWomensDay
Sascha Burton helped lead mechanical integration and test operations for the upcoming SWOT mission that will take @NASA’s first global survey of Earth’s surface water. She is now ramping up to support the NISAR mission with radar antenna deployment test campaigns. #IWD2022
Dr. Tahani Amer has always been passionate about learning the secrets of the universe and how to improve and protect life on Earth. At @NASA she is an Earth Science program executive, working on missions like SWOT, GeoCarb, & CLARREO Pathfinder. #IWD2022 go.nasa.gov/3MHFtgr
Dr. Bridget Seegers is a research scientist in NASA’s Ocean Ecology Lab. She works with the Cyanobacteria Assessment Network (CyAN), helping to monitor and provide warnings for harmful algal blooms. #IWD2022#InternationalWomensDaygo.nasa.gov/3vNhhmr
Dr. Kimberley Miner is a climate scientist at @NASAJPL where she researches and forecasts climate risks. Her work has taken her to the most extreme environments in the world–from Antarctica to Mt. Everest. go.nasa.gov/3pK7Ro9#IWD2022#InternationalWomensDay
Dr. Lola Fatoyinbo Agueh loves to explore new places. As a Research Physical Scientist at @NASAGoddard, she uses satellite data to monitor how forests have changed over time and how they could change in the future. #IWD2022#InternationalWomensDay

NASA confirms: this July was the hottest month on record.🌡️
Our record starts in 1880, when consistent global recordkeeping became possible. It shows an undeniable pattern of increasing global temperatures, primarily from human emissions of carbon dioxide. https://t.co/YqTfn9BMuXgo.nasa.gov/3qwsszU
“This July was massively warmer than any previous July and any previous month on record, which goes back to 1880,” said @NASAGISS Director Gavin Schmidt.
Breathe deeply... and thank phytoplankton. Why? NASA researchers study these tiny creatures to better understand our changing planet. A thread (🧵):
Phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.
Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. Small changes in the growth of phytoplankton may affect atmospheric carbon dioxide concentrations, which would feed back to global surface temperatures.
Each year, strong winds carry more than a billion metric tons of mineral dust from Earth’s deserts and other dry regions through the atmosphere.
How does that dust affect the environment and climate? EMIT is launching soon to help us find out! Here are 5 things to know 👇
1. It will identify the composition of mineral dust from Earth’s arid regions.
From its perch on the @Space_Station, EMIT will map the world’s mineral dust source regions, providing information on the color and composition of dust sources globally for the first time.
2. It will clarify whether mineral dust heats or cools the planet.
Right now, scientists don’t know whether mineral dust has a net heating or cooling effect on the planet. Dust color matters because it determines whether the dust will absorb the Sun’s energy or reflect it.
Earth, the water planet. Its lakes, rivers, and oceans hold a crucial element for life. Earth-orbiting satellites help us track and better understand how this water moves around the globe. #WorldWaterDay
Groundwater – hidden from plain sight – is a vital source of water that can be difficult to track. The GRACE-FO mission detects subtle changes in Earth’s gravity caused by the movement of water, like from groundwater and polar ice. go.nasa.gov/37SVSi3
Our favorite fruits, veggies, and grains depend on water. @NASA missions like SMAP and ECOSTRESS monitor soil moisture and drought, giving farmers a more complete picture and informing agricultural decisions. go.nasa.gov/3Nboljd
“This is a preliminary estimate, but we think the amount of energy released by the eruption was equivalent to somewhere between 4 to 18 megatons of TNT,” said Jim Garvin. 🌋
For comparison, scientists estimate Mount St. Helens exploded in 1980 with 24 megatons and Krakatoa burst in 1883 with 200 megatons of energy. go.nasa.gov/3tRKk7t
