Une rivière entière a disparu au Canada en à peine quatre jours. Scientists say that human-caused climate change rerouted a river. For years, oil and gas companies have plumbed the earth beneath Los Angeles.

Scientists say that human-caused climate change rerouted a river.

And in most cases the companies and city — surprise! — allegedly sidestepped environmental laws in the process. Poor communities of color have suffered the most. “The city disproportionately exposed people of color to greater health and safety impacts,” says attorney Gladys Limón of the environmental justice nonprofit Communities for a Better Environment. In 2015, the Center for Biological Diversity and two local youth groups, Youth for Environmental Justice (which is affiliated with CBE) and the South Central Youth Leadership Coalition, sued L.A. The city settled out of court in September 2016. In Wyoming, climate change is all too real. The scientists used satellite data to measure snow extent over time and found that snow is melting 16 ± 10 days earlier in the 2000s compared with 1972 to 1999.

Last fall, a skipjack tuna, which is more likely to be found in the Galápagos than near a glacier, was caught about 150 miles southeast of Anchorage, not far from the Kenai. This past weekend, race organizers had to truck in snow to the ceremonial Iditarod start line in Anchorage. Sen. Lisa Murkowski (R-Ak.) tweeted a photo of one of the piles of snow with the hashtag #wemakeitwork. Greenland glacial melt is growing factor in rising sea levels. Greenland’s glaciers are far more vulnerable to climate-change-induced warming oceans than previously thought, according to a report released Sunday by the University of California at Irvine and NASA glaciologists.

Greenland glacial melt is growing factor in rising sea levels

The study, published in the journal Nature Geoscience, reveals previously uncharted deep valleys stretching for dozens of miles under the Greenland ice sheet, showing that there are no natural barriers to stop the melting. The findings echo a report released last week showing that glacial melting in West Antarctica is now “unstoppable” because of topographical conditions that, similarly, will not slow the glaciers’ retreat. Bedrock canyons in Greenland sit well below sea level, which means that warming ocean waters will erode the ice much more than previously assumed.

Glacial Balance documentary shows how distant glaciers impact billions of lives. Glacial Balance, directed by Ethan Steinman, is a new documentary that looks at the impact of climate change on glaciers, and how that affects people and ecosystems from the top of mountain to the bottom of valleys (it's all connected).

The filmmakers go on a "journey along the spine of the Andes mountain range, from Colombia to Argentina to know the individuals and lives of those who are first affected by the dwindling tropical glacier reserve, the canaries in the mine. En Antarctique, le glacier du Pin recule inexorablement. Le Monde.fr | • Mis à jour le | Par Stéphane Foucart Le glacier antarctique de l'île du Pin ne s'arrêtera pas de reculer dans les prochaines décennies et deviendra un contributeur important à l'élévation du niveau des mers.

En Antarctique, le glacier du Pin recule inexorablement

C'est la conclusion d'une étude internationale publiée dimanche 12 janvier dans la revue Nature Climate Change, qui a mis à profit les dernières générations de modèles de simulation numérique d'écoulement des grandes masses glaciaires. Les chercheurs se sont intéressés au cas de l'île du Pin, car c'est aujourd'hui le glacier du « continent blanc » qui contribue le plus à l'élévation du niveau des mers.

C'est ce que semble suggérer une nouvelle découverte. D'anciens arbres ont été retrouvés par des chercheurs et sont, pour la première fois depuis 1.000 ans, visibles de tous.

Say goodbye to Yosemite’s largest glacier. Hasta la vista, glacier.

Say goodbye to Yosemite’s largest glacier

The world’s glaciers are withering quickly — researchers say they are contributing to nearly one-third of sea-level rise, despite holding just 1 percent of the planet’s surface ice. And while the glaciers in California’s Yosemite National Park aren’t the largest, they are suffering the same alarming fate as their icy ilk in other parts of the world.

Farewell, great lakes of ice and frozen rivers.

Scientists used satellite images and gravity measurements to peer more closely than ever before at the torturous drip-drip-drip from the world’s glaciers. What they discovered is not really much of a surprise: Ice Age glaciers have been methodically chiseled away by the warming effects of fossil fuel burning. Global warming and black carbon are working fast: Glaciers outside of the Greenland and Antarctic ice sheets are collectively losing an estimated 571 trillion pounds worth of ice annually, the researchers reported in a paper published Thursday in the journal Science. VIENNE - Autriche: poursuite de la fonte des glaciers en 2012, en moyenne de 17 mètres. VIENNE - Sur 95 glaciers surveillés par le club alpin autrichien (ÖAV), 93 ont reculé en moyenne de 17,4 mètres en 2012, tandis que deux ont maintenu leur niveau, a indiqué vendredi l'ÖAV dans son rapport annuel. Le club a également relevé que le glacier du Pasterze dans le massif des Hohe Tauern et du Grossglockner (sud de l'Autriche) avait reculé de 97,3 mètres en 2012, la plus importante fonte pour un glacier jamais enregistrée depuis 1879.

Réchauffement climatique: quel avenir pour les stations de ski? Incredible gigapixel photos let you see Everest’s glaciers before they disappear. Maybe you’ve thought that you’d like to see the Himalayas before you die, but you should consider whether you want to see them before they do. Global warming is putting a deadline on your bucket list. Travel is hard and expensive, though — so it’s good that the GlacierWorks project, headed up by photographer/filmmaker/mountain climber David Breashears, lets you see the glaciers of Everest and nearby mountains in stunning detail, without even getting up from the computer.

Click the photo above to get to the big version on the GlacierWorks site, and then zoom way, way in — even if you’ve seen multi-gigapixel photos, you may be shocked at how much detail you can see.
