2022 ended with a shiver, but the start of 2023 broke a sweat. 🥶🥵 This weather whiplash may have been caused by changes in the polar vortex, the band of strong westerly winds over the Arctic. Details:

Earth’s rivers are always changing. The SWOT satellite tracked how rivers swell and shrink over the course of a year. The data show the seasonal swing may be about 28% less than previous model-based estimates.

Sea level update 🌊 Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, according to a NASA-led analysis. This relatively large jump is due mostly to a warming climate and the development of a strong El Niño.

Sea level update 🌊 In 2024, global sea level rose faster than expected mostly due to ocean water expanding as it warms, or thermal expansion. According to a NASA-led study, 2024’s rise was 0.23 in (0.59 cm) per year, compared to the expected rate of 0.17 in (0.43 cm) per year.

These beautiful, spiraling currents play a big role in Earth’s climate!🌀🌊 These are Agulhas Rings. They carry salt and heat from the Indian Ocean to the Atlantic and are part of a system of ocean currents that shapes the climates of North America, Europe, and Africa.

This is a year’s worth of PACE vegetation data. 🌱 NASA’s PACE satellite can measure subtle changes in leaf color by detecting pigments like chlorophyll, carotenoids, and anthocyanins. Together, these pigments can help scientists assess how healthy the plants are!

To study sea ice thickness, more than one view can help. NASA scientists spent two weeks flying above the Arctic with cutting-edge sensors aboard. When combined with satellite and on-the-ground measurements, the data helps us better understand how the region is changing.

What’s going on here? 🤔 The poles are the only places ICESat-2 can’t gather data. Instead, the satellite’s orbit is designed so that it can better study the edges of the polar ice sheets and sea ice, where much of the change is happening.

NASA’s Artemis program has its eyes on the Moon—but so does Landsat! 🌕 Once a month, the Landsat satellites turn to look at the Moon instead of Earth. Observing the Moon helps calibrate the satellites’ instruments, allowing Landsat to consistently and reliably study our planet.

The 2023 Canadian forest fires released about 640 million metric tons of carbon, according to a NASA study. That’s comparable to the annual fossil fuel emissions of a large industrialized nation. The fires were driven by Canada’s warmest and driest conditions in decades.
