NASA confirms: this July was the hottest month on record.🌡️http://go.nasa.gov/3qwsszU
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.

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.

“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.

#DYK? The Chilean Andes cause a rain shadow effect that results in minimal precipitation in the Atacama Desert, making it one of the driest places on Earth!

In 2022, severe lightning ignited fires in Alaska. 🔥
A year later, @VUamsterdam scientists with @nasa’s ABoVE project are studying the burned tundra to understand how Arctic fires impact plants, soil, permafrost and more. https://go.nasa.gov/3DQ2fiF

NASA’s Disasters Program has been activated in support of the fires in Hawaii. As new information becomes available, maps and data products will be posted on the open-access portal: https://go.nasa.gov/3qqlht2

A fast-moving wildfire in Maui occurred during a period of strong winds and dry conditions. In this #Landsat 8 image from Aug. 8, infrared light shows the locations of active fires in yellow. The fires burned in the town of Lahaina and northwest of Kihei. https://go.nasa.gov/3OSyJPU

Khanun isn't the only storm active in the Pacific right now. The @NOAA-@nasa Suomi NPP satellite captured this view of storms Khanun, Lan and Dora on August 9, 2023.
#NASAEarth
Tropical Cyclone Khanun took a zigzagging path toward the Korean Peninsula.
The @NOAA-@nasa satellite Suomi NPP captured this image on August 8 when the storm had maximum sustained winds of 80 kilometers (50 miles) per hour. https://go.nasa.gov/3qnk6KX

Surface temperatures in cities are usually warmer than in rural and undeveloped lands because of human activities and building materials. Streets are often the hottest part because dark asphalt paving absorbs more sunlight than lighter-colored ones. https://go.nasa.gov/3OOzzNr
#NASAEarth
Roads and buildings grew progressively hotter during a heat wave in Phoenix, AZ, sometimes around 100 degrees Fahrenheit (38 degrees Celsius) after sunset.🌡️
NASA data show a cumulative heating effect, where built surfaces don’t fully cool overnight before the next day’s heat.

Actually there was a nice #Landsat overpass .
The standard RGB shows no obvious plume coming from the #volcano at the time of the overpass, and nothing obvious in the more general view .
But when looking at the NIR composite, there is a distinctive track of brighter clouds
(#volcanotrack) which is a telltale of clouds contaminated by the volcano.
This coincides with the similar picture taken by the #MODIS
sensor, which has coarser resolution.
Seasonal warmth led to the rapid disintegration of sea ice near two large outlet glaciers in Greenland. 🌊🧊
A pocket of persistent open water – or polynya – had formed within the sea ice on July 21 (left). By July 25 (right), the sea ice had broken out. https://go.nasa.gov/3YntuL7

NASA’s upcoming PACE mission will help scientists learn more about ocean ecology, including the species of phytoplankton present in blooms and the rates of their growth.
PACE is launching no earlier than January 2024. https://go.nasa.gov/45jhkFq

A break in the clouds above the Barents Sea, one of the cloudiest places in the world. ☁️🌊☁️
Milky blue swirls of phytoplankton are present in this view from @nasa’s Terra satellite on Aug. 3. https://go.nasa.gov/3OxCGIq
#NASAEarth
Prolonged heavy rains in northern Australia set off new plant growth across Channel Country.
More vegetation grew in areas like the Lake Eyre Basin, seen in these enhanced-color images from @nasa’s Terra satellite.
An upcoming @nasa mission called PACE will see the ocean in more colors than ever before, allowing researchers to understand which species of phytoplankton are present in blooms. https://go.nasa.gov/3OIxi6g

An ocean of color 🎨
Swirls of phytoplankton and sediment colored the coastline of Vancouver Island in shades of turquoise and green. The @NOAA-20 satellite captured this image on July 26, 2023. https://go.nasa.gov/3KrDOvI

Although summer 2023 has been unusually hot in parts of the U.S., it has been a quiet year for fires. NASA’s new initiative, FireSense, aims to match NASA data and resources to fire managers on the ground. https://go.nasa.gov/3QlKejS

The Elkhorn Fire, which started on July 24, is the largest fire in Idaho. @nasa’s Terra satellite captured this image of the smoke appearing to settle into the deep valleys carved by the Salmon River.
#NASAEarth
Wildfire season is picking up in the U.S.
60 fires are burning across nine states in the western U.S., fueled by hot and dry conditions. On August 1, #Landsat 9 captured this image of smoke streaming away from the Bedrock Fire in Oregon. https://go.nasa.gov/3Kscai8

Catching crop disease early 🍇
From the air, a NASA instrument helps spot a wine grape disease before it’s visible to the human eye. This remote sensing technique could help detect early signs of infection in this and other crops. https://go.nasa.gov/43XFeFk

The answer is Windpark Fryslân, the largest freshwater wind farm on Earth!
The array of 89 wind turbines, located in Lake IJssel in the Netherlands, produces enough electricity to power about half a million homes. ⚡🏠 https://go.nasa.gov/3DJubVC

Good evening, Türkiye. 🌃
An astronaut aboard the @Space_Station took this nighttime photograph of the coastal Mediterranean city of Antalya, Türkiye in September 2022, showing the sharp contrast between urban infrastructure and natural areas. https://go.nasa.gov/3q5u43v

Scientists from the Institute of Earth Sciences at @uni_iceland calculated that the eruption was discharging about 12 cubic meters of lava per second on July 17, similar to the 2021 and 2022 eruptions.

Water vapor, carbon dioxide & sulfur dioxide are the most abundant gases in volcanic plumes.
According to satellite sensors like TROPOMI and OMI, winds have mostly pushed the plume over the Atlantic Ocean, but has also affected air quality in Reykjavík.

The configuration of the polar vortex may have played a role in unleashing bitter cold followed by record warmth in North America.
