ESA: Larsen-C crack across Antarctic ice shelf

As you probably know, an ice sheet about the size of New Jersey is about to be broken off from Antarctica. The ESA Copernicus Sentinel-1 satellite mission is continually monitoring the growing crack in Antarctica’s Larsen-C ice shelf. When the ice shelf breaks off or ‘calves’, it will create one of the largest icebergs ever …

Chris Bowler: The Future of Ocean Ecosystems

This Harvard University lecture features Chris Bowler, who explores how past environments affected diatoms and can thus help understand how climate change will affect them in the future.  

Two-thirds of Great Barrier Reef now devastated by coral bleaching

It was reported that 67 percent of the northern part of the Great Barrier Reef in Australia suffered coral bleaching during the later half of 2017. Now, researchers have found that the reef this year been exposed to bleaching again. This time, the part in the middle was hit the hardest. While El Niño was …

Australian National University: Humans have caused climate change for 180 years

An international research project has found human activity has been causing global warming for almost two centuries, proving human-induced climate change is not just a 20th century phenomenon. Lead researcher Associate Professor Nerilie Abram from The Australian National University (ANU) said the study found warming began during the early stages of the Industrial Revolution and …

Nature Video: Glaciers lost in time

As the world warms, Greenland melts. We know that sea levels are rising, but it’s hard to predict how quickly Greenland’s glaciers might disappear into the sea. Anders Anker Bjørk and his colleagues are using 1930s photos to examine how these glaciers have changed over the last 80 years, and what their future might hold.

Lund University: How increased vegetation in the Arctic region may counteract global warming

Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden together with the University of Copenhagen shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting …

Harvard University: A focus on earth’s other greenhouse gas problem

Methane doesn’t get top billing in the global climate debate, but it’s a more potent greenhouse gas than headline-grabbing carbon dioxide and the major component of natural gas that heats our homes and generates our electricity. Harvard scientist Steven Wofsy is heading a project to both track escaped methane from our natural gas infrastructure and …

TED: This country isn’t just carbon neutral — it’s carbon negative | Tshering Tobgay

Deep in the Himalayas, on the border between China and India, lies the Kingdom of Bhutan, which has pledged to remain carbon neutral for all time. In this illuminating talk, Bhutan’s Prime Minister Tshering Tobgay shares his country’s mission to put happiness before economic growth and set a world standard for environmental preservation.  

Colombia University: Klaus Lackner Takes Step Toward Workable Carbon Capture Technology

Klaus Lackner’s approach to slowing global warming is to clean up the atmosphere literally. In his lab at Columbia’s Engineering School, Lackner is working on technology to scrub carbon dioxide from the air, reducing levels of the harmful greenhouse gas that plays a major role in the increase of the Earth’s temperature. ?We need ways …

TED: Al Gore | The Case for Optimism on Climate Change

Why is Al Gore optimistic about climate change? In this spirited talk, Gore asks three powerful questions about the man-made forces threatening to destroy our planet — and the solutions we’re designing to combat them.  

TED Ed: Can wildlife adapt to climate change? – Erin Eastwood

With rising temperatures and seas, massive droughts, and changing landscapes, successfully adapting to climate change is increasingly important. For humans, this can mean using technology to find solutions. But for some plants and animals, adapting to these changes involves the most ancient solution of all: evolution. Erin Eastwood explains how animals are adapting to climate …

American Museum of Natural History: Science Bulletins: Super Corals—For the Future (1 of 3)

Marine biologists in Hawaii investigate so-called “super corals,” which thrive even as ocean temperatures rise. In For the Future, learn how corals create underwater cities bustling with life, and explore a reef where healthy and dying corals live side by side.  

National Geographic: Photo Evidence: Glacier National Park Is Melting Away

Glacier National Park is losing its iconic glaciers to a changing climate. In the mid-1800s, this Montana landscape was covered by 150 glaciers—today only 25 remain. To show the decrease in glacier size, scientists from the USGS Northern Rocky Mountain Science Center photograph the same areas where glaciers were photographed in the early 1900s. Dan …
