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 #InternationalWomensDay go.nasa.gov/3vNhhmr Dr. Bridget Seegers Headshot
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. Kimberley Miner headshotDr. Kimberley Miner in a ha...
Growing up, Dr. Hui Su watched weather balloons released after school. Today, she is an Earth scientist at @NASAJPL who studies clouds and storms. #IWD2022 #InternationalWomensDay go.nasa.gov/35BfOoE Dr. Hui Su at the Kennedy S...
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
Line graph of July temperatures in NASA’s temperature record. The bottom axis starts in 1880 (left) and goes to 2023 (right). On the X axis are temperature anomalies in degrees Celsius, from negative 0.5 to 1.0. A red line starts at zero and zig-zags up and down from year to year, but the overall trend steadily increases. By the end of the visualization, the red line spikes up over a 1.1 degree Celsius anomaly for July of 2023.
“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.
Our planet is already feeling the effects of record-breaking temperatures and climate change.

2023 brought sweltering heat waves, record high Atlantic sea surface temperatures, and fires in Canada sending smoke thousands of miles away.

2022 was effectively tied for the 5th warmest year on record, according to @NASA analysis. 🌏🌡

@NOAA’s record indicates 2022 is the 6th warmest. The past 9 years are the warmest years since at least 1880. go.nasa.gov/3VZBM9a
Earth in 2022 was about 1.9F (or about 1.1C) warmer than the late 19th century average.

This visualization shows how Earth has warmed since 1880. Red spirals indicate warmer than average temperatures.

2022 was another La Niña year, a natural climate pattern of Pacific Ocean temperatures that tends to have a cooling effect.

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 👇 Officials from NASA and JPL...
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 Artist rendition of the two...
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 Tractor over a soybean field

A mapping effort led by @NASAGoddard's chief scientist shows how the explosive volcanic eruption at #Tonga's #HungaTongaHungaHaapai obliterated the island. go.nasa.gov/3rE8jo4
“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
