Narwhal Tusks Record Changes in the Marine Arctic

Narwhal Tusks Record Changes in the Marine Arctic

By Kimberly M. S. Cartier As the Arctic continues to warm, climate changes cascade into the marine environment. Top predators like polar bears, beluga whales, and narwhals are affected by shifting seasonality and loss of the Arctic sea ice that shapes where they live and what they eat. Moreover, changes in ocean currents alter the […]

    Why Is Melting Ice a Big Deal?

    Why Is Melting Ice a Big Deal?

    By Stuart Braun The melting of the polar ice caps has often been portrayed as a tsunami-inducing Armageddon in popular culture. In the 2004 disaster movie The Day After Tomorrow, the warming Gulf Stream and North Atlantic currents cause rapid polar melting. The result is a massive wall of ocean water that swamps New York […]

    Ancient Leaves Preserved Under Greenland’s Ice Reveal Climate Secrets

    Ancient Leaves Preserved Under Greenland’s Ice Reveal Climate Secrets

    By Andrew Christ and Paul Bierman In 1963, inside a covert U.S. military base in northern Greenland, a team of scientists began drilling down through the Greenland ice sheet. Piece by piece, they extracted an ice core 4 inches across and nearly a mile long. At the very end, they pulled up something else – […]

    How Do Arctic Foxes Hunt in the Snow?

    How Do Arctic Foxes Hunt in the Snow?

    By Jacob Job Maybe you’ve seen a video clip of a fluffy white fox moving carefully through a frozen landscape. Suddenly it leaps into the air and dive-bombs straight down into the snow. If so, you’ve witnessed the unusual hunting skills of an Arctic fox. During winter at the most northern parts of Earth, snow […]

    Thawing Permafrost Is Full of Ice-Forming Particles That Could Get Into Atmosphere

    Thawing Permafrost Is Full of Ice-Forming Particles That Could Get Into Atmosphere

    By Jessie Creamean and Thomas Hill The Research Brief is a short take about interesting academic work. The Big Idea Permafrost – frozen soil in the far north – is thawing, releasing greenhouse gases and long-lost microbes. But one thing that scientists have not studied extensively is whether permafrost contains certain kinds of particles that […]

    Crazy Idea? One of World’s Coldest Towns Bids to Host 2032 Summer Olympics

    Crazy Idea? One of World’s Coldest Towns Bids to Host 2032 Summer Olympics

    By Jessica Corbett With temperatures across the globe — and particularly in the Arctic — rising due to lackluster efforts to address the human-caused climate crisis, one of the coldest towns on Earth is throwing its hat in the ring to host the 2032 Summer Olympics. Salla is located in Finland’s Lapland region and touts […]

    Earth’s Ice Loss Reflects Worst-Case Scenario, New Study Finds

    Earth’s Ice Loss Reflects Worst-Case Scenario, New Study Finds

    Earth’s ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows. “It was a surprise to see such a large increase in just 30 years,” said Thomas Slater, a study co-author. There have been […]

    NOAA Names 2020 Second-Hottest Year on Record; NASA Says It Tied for Hottest Ever

    NOAA Names 2020 Second-Hottest Year on Record; NASA Says It Tied for Hottest Ever

    By Jeff Masters, Ph.D. Earth had its second-warmest year on record in 2020, just 0.02 degrees Celsius (0.04°F) behind the record set in 2016, and 0.98 degrees Celsius (1.76°F) above the 20th-century average, NOAA reported January 14. NASA and the European Copernicus Climate Change Service rated 2020 as tied with 2016 as the warmest year […]

    Increase in Lightning Strikes Expected to Ignite More Wildfires

    Increase in Lightning Strikes Expected to Ignite More Wildfires

    As the planet’s temperature warms, the frequency of lightning strikes is expected to grow with it, Environmental Journal reported. Currently, lightning strikes the earth’s surface nearly eight million times a day. This number is expected to dramatically increase as global temperatures rise, according to a study published by Science. The U.S., for example, could experience […]
