A Tulane University-led study published in Nature Geoscience reveals that melting North American ice sheets were the primary driver of dramatic sea-level rise at the end of the last ice age, overturning long-held assumptions that Antarctica played the larger role. Between 8,000 and 9,000 years ago, retreating North American ice sheets caused more than 30 feet (10 meters) of global sea-level rise, reshaping scientists’ understanding of Earth’s climate history.

Combing through 20 years of images from the European Space Agency’s Mars Express and ExoMars Trace Gas Orbiter spacecraft, scientists have tracked 1039 tornado-like whirlwinds to reveal how dust is lifted into the air and swept around Mars’s surface.

Published today in Science Advances, their findings – including that the strongest winds on Mars blow much faster than we thought – give us a much clearer picture of the Red Planet’s weather and climate.

And with these ‘dust devils’ collected into a single public catalogue, this research is just the beginning. Besides pure science, it will be useful for planning future missions, for example incorporating provisions for the irksome dust that settles on the solar panels of our robotic rovers.
