Sea level rise caused by global warming is going to wash away many popular beaches in Southern California.
The glaciers in the Hohe Tauern region of the Austrian Alps have receded by hundreds of feet in just the past few decades.

This set includes illustrations for some of my most recent stories in various environmental and climate news publications and if you’re a regular Summit Voice reader who is not on Twitter or Instagram, I’m providing a few links here.
A couple of weeks ago, I wrote about how some of Greenlands coastal glaciers already passed passed a climate change tipping point about 20 years ago. Because of the physical processes of snowmelt and runoff, these glaciers are going to disappear even if global greenhouse gas emissions are cut to zero immediately. You can read the story here.
For Pacific Standard, I put together an environmental photo essay on bumblebees, some of the most important pollinators of wildflowers, especially in mountain regions and also in the far north. Bumblebees are important because they are cold-tolerant, so they’re out and about visiting early blooms while other pollinators are dormant. They’ll also fly long distances to visit a single flower. Without them, some species would go extinct. Check out the photo essay here.
You might have seen the recent Summit Voice story on beach erosion and how it’s going to wash away some world famous surf spots along the California coast, and in other areas where coastal strands are ringed by mountains, but if you missed it, you can see it here.
I also wrote about the annual Austrian glacier report for Deutsche Welle, a great global news organization that really does in-depth environmental and climate reporting. You can visit the DW website here, or follow them on Twitter for a daily feed. And my story on the dwindling glaciers is here.
Finally, in a critical story for Colorado and the rest of the West, I reported on how we are losing the war on wildfires and how we need to change our way of thinking about forests and fires in an era of rapid climate change. The story is online at Pacific Standard.
Environmental protections are under attack on every front and the far North is no exception. Alaska’s senators Lisa Murkowski and Dan Sullivan, both Republicans, appear willing to risk fragile ocean environments for a few more petrodollars, so they’ve opportunistically introduced a bill that would expand oil and gas drilling in the Arctic Ocean and Cook Inlet, where a recent gas leak persisted for several months, according to InsideClimate News.
Senate Bill 883 seeks to reverse protections established by President Obama in Dec. 2016 and force the Department of the Interior to quickly approve new oil and gas leasing.
“It’s not possible to drill safely in the Arctic, as we just saw from the leaking oil and gas well on the North Slope,” said Miyoko Sakashita, ocean programs director at the Center for Biological Diversity. “This legislation’s nothing more than a giveaway to oil companies. It’ll hurt Alaska’s healthy habitat and endangered wildlife.” Continue reading “Alaska’s senators want more offshore drilling in Arctic waters”→
Mixing waters may hasten arrival of ice-free Arctic Ocean summers
In yet another sign that the balance of Earth’s climate system is being perturbed by global warming, scientists are documenting how a steady intrusion of water from the Atlantic is undermining sea ice in the Arctic Ocean.
Study documents rising amount of sea-bottom debris
There’s more direct evidence that plastic pollution is increasing rapidly in the remote Arctic Ocean, according to German scientists, who have tracking sea-bottom litter at two research stations since 2002. The Hausgarten deep-sea observatory network includes a total of 21 stations in the Fram Strait, between Greenland and Svalbard.
So far, there’s little sign of a post El Niño drop in global temperatures, according to the European Copernicus Climate Change Service, which has new data showing that last month was the second-warmest February on record for Earth. According to the report, February 2017 “extended the spell of exceptional global warmth that has now lasted since mid-2015.”
The loss of Arctic sea ice may not lead directly to an increase in cold weather extremes in Europe, according to scientists who studied the links between Arctic changes and mid-latitude weather. In the study, scientists with the University of Exeter found that dwindling sea ice does affect the North Atlantic Oscillation (NAO) weather phenomenon, which affects winter weather conditions in Northern Europe, in places such as the UK, Scandinavia and the Baltic states.

In the past 20 years, acidified waters have expanded in the Arctic ocean, spreading northward from Alaska’s Chukchi Sea coastline to just below the North Pole. The pool of acidified water is also getting deeper, from 100 to 250 meters, according to a new study in the journal Nature Climate Change.
In a press release, the researchers said it’s the first time they’ve documented such a rapid and large-scale increase in acidification, “at least twice as fast as that observed in the Pacific or Atlantic oceans,” according to University of Delaware professor Wei-Jun Cai.
The changes will impact different types of ocean life, including tiny marine snails known to be susceptible to ocean acidification, said NOAA scientist Richard Feely. Other Arctic species potentially at risk from ocean acidification are fisheries of shrimp and varieties of salmon and crab — all important food sources for indigenous communities.
