Voluntary program won’t help curb rapidly rising emissions, according to critics
Climate activists and conservation groups say a voluntary international airline carbon-trading scheme doesn’t go nearly far enough to curb greenhouse gas pollution.
Growth in the aviation sector puts the industry on track to triple emissions by 2050, but the new carbon-offset program won’t even take effect until 2021 and is slated to remain voluntary through 2027. According to the climate-action advocates, the deal, adopted by the International Civil Aviation Organization (ICAO), only covers about a quarter of total emissions and shifts the industry’s growing carbon debt on to third parties using what could be questionable carbon-offset credits.

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.

Heat-trapping greenhouse gases may dessicate Colorado River Basin
It’s very likely the southwestern U.S. will be hit by droughts unlike any seen since the region was settled by Europeans. Global warming has driven the odds of a 10-year drought to at least 50 percent, and the chances of a 35-year megadrought range from 20 to 50 percent during the next century, according to a new study led by researchers with Cornell, the University of Arizona and the U.S. Geological Survey.
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.
A slowdown of a key heat-carrying Atlantic current may not be due to melting Arctic ice, but to changes in the Southern Hemisphere, according to University of Washington scientists studying how climate change may affect global wind and ocean flows.
Their new study, published in the journal Geophysical Research Letters, analyzed data from satellites and ocean sensors off Miami that have tracked the Atlantic overturning circulation for more than a decade. Together they show a definite slowdown since 2004, confirming a trend suspected before then from spottier data.
The Paris climate agreement has reached the milestones needed to take effect, as 70 countries, representing almost 57 percent of global emissions, have formally signed on to the deal. According to the United Nations, Canada, the European and Nepal deposited their instruments of ratification with the global body Wednesday, Oct. 6. The agreement, aimed at limiting global warming to 1.5 degrees Celsius above the pre-industrial level, will become effective Nov. 4.
In a prepared statement, UN Secretary General Ban Ki-moon said, “Global momentum for the Paris Agreement to enter into force in 2016 has been remarkable. What once seemed unthinkable is now unstoppable. ”
Under the agreement, more than 190 countries agreed late last year to try and decarbonize the world’s energy systems by the middle of the century to end the buildup of heat-trapping pollution that has already raised the world’s average temperature by about 1 degree Celsius since 1850. In the past few months, the global temperature has spiked near the 1.5 degree threshold. Climate scientists agree that capping the rise at 2 degrees is critical to avoiding catastrophic climate change impacts like deadly droughts and heatwaves, floods and other extreme weather events.
The treaty also requires richer countries to set up a mitigation fund to help developing countries adapt to impacts. All countries party to the deal must submit individual plans and update them on a regular basis.
Commenting on the news from the Rose Garden, President Barack Obama said that, if the world follows through on the deal’s terms, “history may well judge it as a turning point for our planet.” More from the White House here.
Thank you to every nation that moved to bring the Paris Agreement into force. History will judge today as a turning point for our planet.
Making it real will require a massive transformation of the world’s economy, and despite the good intentions, there are not many strong signs that will actually happen soon enough. Some recent studies have also warned that the planet is just 15 years away from hitting the 1.5 degree threshold, and that without immediate and massive greenhouse gas cuts, the 2-degree Celsius mark will be passed as early as 2050.
Understanding the urgency, the world community may try to ramp up climate action as soon as the COP22 climate conference in Marrakesh in November.
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.
