Unsustainable fishing is pushing the species to the brink of oblivion
Federal regulators are one step closer to putting Pacific bluefin tuna on the endangered species list, as humankind’s insatiable appetite for resources drives the fish to the edge of extinction. The announcement by the National Marine Fisheries Service came in response to a petition filed by conservation groups, who say bluefin tuna populations have declined by about 97 percent since the advent of industrial fishing operations.

During out last reporting trek we visited a unique wildnerness area in central Austria, in the far eastern reaches of the Alps, to learn how resources managers and citizens perceive wilderness in the heart of a densely populated country. The area is the watershed of the Ybbsteinbach, which flows into the Ybbs, and then into the Danube, which is really a mountain river at heart. Learning how resources managers are trying to recreate a true undisturbed wilderness area here was inspiring, and we have a story coming up, but for now enjoy these autumn riverside scenes and visit our online gallery for more landscape photography. And learn more about our reporting in the Alps here.
Australian scientists document early start to melt season
Australian scientists say Antarctic sea ice started its annual spring retreat early this year and has set new daily record lows for extent during late September — during the Austral spring, when Antarctic sea ice is at a maximum.
In a press release, the Antarctic Climate & Ecosystems Cooperative Research Centre said the sea ice extent started its annual retreat early, just two years after winter sea ice extent around Antarctica reached a new record high in September 2014, when it exceeded 20 million square kilometres for the first time since satellite measurements began in 1979.
This year, Antarctic sea ice began its annual spring retreat about four weeks earlier than average, after peaking at 18.5 million square kilometres on 28 August 2016, which was close to the lowest winter maximum on record.
Congress may not be able to get it together to deal with issues like crumbling infrastructure or deadly opiate epidemics, but when it comes to trying to strip Americans of their unique public lands heritage, there’s no shortage of legislation.
The Center for Biological Diversity is warming there are four bills pending in the House and Senate natural resource committees that could affect public lands — and not in a good way. One of the measures would block the creation of new national monuments and parks, while others could enable the transfer of federally managed public lands to state governments.

Oil and gas exploration would have widespread effects on marine mammals
Conservation advocates have long been saying that blasting the Gulf of Mexico with seismic airguns to find more oil and gas beneath the seafloor would result in unacceptable harm to marine mammals and other marine life, and a new draft environmental study by the Bureau of Ocean Energy Management seems to confirm those concerns.
The study was completed under the terms of a court-ordered settlement of a lawsuit brought by environmental groups. It shows that the blasting would have widespread impacts on marine life, including injuries to endangered sperm whales and Bryde’s whales. The draft report outlines possible mitigation measures, including closure areas where seismic blasting would be banned, and reductions in the amount of activity permissible each year.

Fish die-offs spread, winter retreats and ocean currents are changing
By Bob Berwyn
My recent reporting for InsideClimate News includes coverage of the massive Yellowstone fish kill, something that anglers and fisheries managers in Colorado also should probably be prepared for as rivers warm to a level that is conducive to the spread of parasites. Read the details here: Fish Deaths in Montana’s Yellowstone River Tied to Warming Waters.
I also explored how Austria is preparing for climate change. The mountainous country has seen its average temperature increase at nearly twice the global average in the past century, with huge implications for water supplies, agriculture, urban heatwaves and tourism. But rather than argue about the causes, Austrians are actively trying to figure out how to make their society and ecosystems more resilient to the changes ahead. Read here: Austria Braces for Winter’s Retreat.
There’s other research showing a significant shift in most key ocean currents that run along the edges of continents. Those currents are key drivers of weather systems and the changes documented by scientists suggest that the currents are strengthening and transporting more heat, which is affecting weather in densely populated areas. China and Japan, in particular, can expect more devastating storms and typhoons in the future: In Warming Oceans, Stronger Currents Releasing Heat in Bigger Storms.
It seems pretty clear that we have to try and prevent runaway climate change and the way to do that is to stop spewing heat-trapping pollution into the sky. We need to bite the bullet and figure out how to decarbonize our energy systems and economy in the most rational way, which means making plans and decisions now, not in 20 years. Every additional dollar used to subsidize fossil fuels, or to build fossil fuel infrastructure, is another nail in our own coffin. Offshore wind power is still grossly under-utilized in the U.S. but that is starting to change.
Scientists say Paris deal is not nearly enough to curb harmful global warming
By Bob Berwyn
The Paris climate agreement will likely be triggered into force within the next few weeks, which marks the beginning — not the end — of an intense effort to try and cap global warming before the planet is overwhelmed by heatwaves, droughts and super storms.
