    Watch NASA’s mesmerizing new visualization of the 2017 hurricane season

    View the video

    How do you observe the invisible currents of the atmosphere? By studying the swirling, billowing loads of sand, sea salt and smoke that winds carry. A new simulation created by scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., reveals just how far around the globe such aerosol particles can fly on the wind.

    The complex new simulation , powered by...

    Humans are driving climate change, federal scientists say

    It is “extremely likely” that humans are driving warming on Earth since the 1950s. That statement — which indicates a 95 to 100 percent confidence in the finding — came in a report released November 3 by the U.S. Global Change Research Program. This interagency effort was established in 1989 by presidential initiative to help inform national science policy.

    Wind may be driving the melting of East Antarctica’s largest glacier

    View the video

    The wind is helping to awaken one of Antarctica’s sleeping giants. Warm ocean waters, driven inland by winds, are undercutting an ice shelf that holds back a vast glacier from sliding into the ocean, researchers report November 1 in Science Advances.

    Totten Glacier is East Antarctica’s largest glacier, with a drainage basin encompassing about 550,000 square...

    Climate change may threaten these bamboo-eating lemurs

    The only lemurs so dependent on bamboo that they gnaw on hardened, nutrient-poor stems during the dry season might dwindle away as those seasons grow longer.

    Reconstructing the history of the greater bamboo lemur (Prolemur simus) in Madagascar suggests that drier areas over thousands of years already have lost their populations. As the region dries further due to climate change and the...

    As ice retreats, frozen mosses emerge to tell climate change tale

    SEATTLE — Some mosses in the eastern Canadian Arctic, long entombed in ice, are now emerging into the sunlight. And the radiocarbon ages of those plants suggest that summertime temperatures in the region are the warmest they’ve been in tens of thousands of years.

    As the planet warms and the ice retreats on Canada’s Baffin Island, the change is revealing plants long buried beneath the ice...

    ‘Killer Hurricanes’ reconstructs the past to predict storms of the future

    In 1780, a powerful hurricane swept across the islands of the Caribbean, killing an estimated 22,000 people; 5,000 more died of starvation and disease in the aftermath. “Our planet is capable of unleashing extreme chaos,” begins the new NOVA documentary “Killer Hurricanes,” set to air November 1 on PBS.

    To describe the human impact of such powerful tropical cyclones, the documentary...

    When the Larsen C ice shelf broke, it exposed a hidden world

    Teams of scientists are gearing up to race to the Antarctic Peninsula to find out what happens in the immediate aftermath of a massive ice calving event. In July, a Delaware-sized iceberg broke off from Antarctica’s Larsen C ice shelf (SN: 8/5/17, p. 6). Now, several research groups aim to assess the stability of the remaining ice shelf, map the region’s seafloor and study a newly exposed...

    During El Niño, the tropics emit more carbon dioxide

    The tropics of Asia, Africa and South America all puffed out more carbon dioxide during the strong 2015–2016 El Niño than during the 2011 La Niña, new satellite data show. Because El Niño’s warmer, drier conditions in tropical regions mimic the effects of climate change expected by the end of the century, those observations may be a sobering harbinger of the tropics’ diminishing role as a...

    Castaway critters rafted to U.S. shores aboard Japan tsunami debris

    The 2011 tsunami that devastated Japan’s coast cast an enormous amount of debris out to sea — way out. Japanese marine life took advantage of the new floating real estate and booked a one-way trip to America. From 2012 to 2017, at least 289 living Japanese marine species washed up on the shores of North America and Hawaii, hitching rides on fishing boats, docks, buoys, crates and other...

    Tropical forests have flipped from sponges to sources of carbon dioxide

    The world’s tropical forests are exhaling — and it’s not a sigh of relief. Instead of soaking up climate-warming gases on balance, these so-called “lungs of the planet” are beginning to release them.

    A new study based on analyses of satellite imagery of tropical Asia, Africa and the Americas suggests that tropical forests contribute more carbon dioxide to the atmosphere than they remove...
