Persistent Warming Driving Big Arctic Changes

Persistent Warming Driving Big Arctic Changes

Not every year can be a record setter in the Arctic. But records are only one small piece of a larger puzzle that shows persistent change in the Arctic. And that change hasn’t slowed according to this year’s Arctic Report Card released at the American Geophysical Union’s Fall Meeting on Wednesday. Long-term trends in rising temperatures, spirali… Read More

Acidic Oceans Could Quiet Coral Reefs

Acidic Oceans Could Quiet Coral Reefs

Doug E. Fresh may have some competition in the beatboxing arena from unlikely source. It’s not from some underground phenom but rather an underwater rising star, or well, fish. Take a listen to this beat laid down by a croaker fish off the coast of Indonesia. A rhythmic thumping provides the beat for an otherwise ambient ocean noise track. “This o… Read More

Greenland’s Ice Sheet Shifts Could Speed Melt

Greenland’s Ice Sheet Shifts Could Speed Melt

New discoveries in Greenland’s warming ice sheet tell a chilling tale of change in its depths. Mysterious under-snow lakes pockmarking its edges and deep layers of ice at higher elevations both point to changes that could hasten melt and send water cascading into the ocean, pushing global sea levels ever higher. Researchers revealed findings of th… Read More

The End and Beginning of the Arctic

The End and Beginning of the Arctic

In the winter of 2013–14, hundreds of milk-white birds with luminous yellow eyes and wingspans of up to 5 feet descended on beaches, farmers’ fields, city parks and airport runways throughout southern Canada and the United States. Traditionally, snowy owls spend most of their time in the Arctic and subarctic regions. But every four years or so … Read More

Atmospheric River, Heavy Rain Roar Into California

Atmospheric River, Heavy Rain Roar Into California

For the second time in a week, heavy rain is making an appearance in drought-weary California. This round comes courtesy of the tropics via an appropriately named “atmospheric river” that is sending precipitation across the state, bringing a modicum of relief. While the storm may marginally help the state-wide drought, relief could come at a high p… Read More

Robotic Floats Will Reveal Southern Ocean’s Mysteries

Robotic Floats Will Reveal Southern Ocean’s Mysteries

This December, Hannah Zanowski, a graduate student at Princeton University, will travel to Cape Town, South Africa, bundle up in something warm, and board a German research icebreaker called the Polarstern. Over the next eight weeks, the ship will make its way from the southern tip of Africa to the bottom of South America via the Weddell Sea off … Read More

Earth, Now Available in Ultra High Definition

Earth, Now Available in Ultra High Definition

A year in weather in high definition was pretty amazing and so was a similar sharp take on the spring equinox. But a five day view of the planet from space in ultra high definition is a whole other level of awesome. The imagery from mid-May 2011 comes courtesy of Russia’s high flying Elektro-L weather satellite, which sits in high Earth orbit more … Read More

40 Years of Scratching Reveals Ocean Acidification Data

40 Years of Scratching Reveals Ocean Acidification Data

As carbon dioxide levels increase due largely to human emissions, the world’s oceans are becoming highly corrosive to a number of organisms that call it home. But the rate of acidification and related changes are anything but uniform. That’s why a new study aims to set a baseline for nearly every patch of saltwater from sea to acidifying sea so tha… Read More
