The Intergovernmental Panel on Climate Change, the world's leading climate science body, declared in a new report that global warming is wreaking havoc "on all continents and across the oceans," with the worst yet to come. But by far the most severe impacts will strike the poorest countries that bear little or no historical responsibility for causing climate change, the report said.
"Those countries who have contributed least to the manifestation of this problem are in jeopardy of being the most vulnerable to it," said Gary Yohe, an economist at Wesleyan University and a coordinating lead author of the IPCC report. "The poor, the young, the old and the people who live along the coasts will be hit the hardest."
The message of "climate justice" comes through in the 2,500 pages of the IPCC's new report released on Monday in Japan. The hot-button concept frames global warming as an ethical issue and involves developed nations financing poor nations' climate-related losses, damage and adaptation efforts.
It's been a year since a broken oil pipeline sent an estimated 210,000 gallons of Canadian dilbit into an Arkansas neighborhood, but there's still a long list of unknowns about the spill.
The most critical mystery yet to be resolved for the public: What caused ExxonMobil's Pegasus pipeline to break apart March 29 while the line was running well below its maximum approved pressure?
All the public knows now is that a metallurgical report concluded that substandard pipe-making methods left tiny cracks near the lengthwise seams on the 1940s-era northern Pegasus pipe. Those micro-cracks grew and merged during service to become dangerous "hook cracks," and then something—or a combination of things—caused at least one hook crack to open up a 22-foot gash in Mayflower, Ark.
The report didn't determine what caused long-dormant manufacturing defects to awaken and expand, and didn't say whether the way the Pegasus was being operated, or the properties of the dilbit had a role in promoting crack growth on the pipe.
The metallurgical report was completed in July. There's been no news about the cause or the pipeline's condition since. Exxon has only said that it was conducting additional tests on the line to ferret out all the factors that contributed to the failure.
Sometime before April 7, ExxonMobil will finally tell regulators and the public why its 1940s-era Pegasus oil pipeline split open in Mayflower, Ark. last March, spilling thick Canadian dilbit into a neighborhood and nearby cove.
Will Exxon just send out a statement announcing its conclusions about the cause or causes of the Pegasus spill? Or will it also make public the details and supporting evidence behind its determination? If Exxon doesn’t provide those details, will they be made available by the Pipeline and Hazardous Materials Safety Administration (PHMSA), which regulates most U.S. pipelines?
Actions to date aren’t encouraging, according to some pipeline experts and Arkansas officials. "It's been a constant process of trying to get information, trying to get data, trying to evaluate the tools and technology and processes that Exxon uses to ensure the integrity and safety of this pipeline," said John Tynan former watershed protection manager for Central Arkansas Water (CAW) and now its director of public affairs.
A State Department contractor for the Keystone XL that has been under attack for alleged conflicts of interest has withdrawn from contract negotiations to review a lesser-known but still controversial tar sands pipeline: Enbridge's Alberta Clipper.
The unusual move has led some legal and industry experts to question whether public and political pressure against the company might have played a role in the decision. "There's no doubt it is in the back of our minds," said David McColl, an energy analyst for Morningstar, an investment research company, who focuses on Enbridge. Federal contracts for major projects can be lucrative—potentially worth into the millions, depending on the scope and scale of the work and the agency involved—and are often the bread-and-butter of consulting firms' business.
On March 15, 2013, the State Department announced it had chosen ICF International, a technology and policy consulting group based in Fairfax, Va., to carry out the environmental review of Enbridge's proposed expansion of the Alberta Clipper oil pipeline to transport 880,000 barrels a day from Canada to Wisconsin.
The southern leg of ExxonMobil's idled Pegasus oil pipeline, a segment regulators say is susceptible to seam ruptures, might be restarted as early as this week. Residents along the pipeline and others, however, have no idea whether—or how—the pipeline has been made safe because the information is not publicly available.
"We're all still in the dark," said Carl Weimer, executive director of the Pipeline Safety Trust, a nonprofit watchdog group based in Bellingham, Wash.
In a Jan. 31 letter seeking clearance to reopen the 63-year-old Pegasus southern section, Exxon told the federal Pipeline and Hazardous Materials Safety Administration (PHMSA) that it "intends to initiate restart activities no later than March 28, 2014." A copy of the two-page letter was provided to InsideClimate News by PHMSA, but it is one of many important documents that have not been publicly released or made available on the agency website dedicated to Pegasus updates. One of those key documents, the restart plan for the southern leg, is still being withheld.
"I think it's terrible that there's something going on that affects people's lives that you really can't get any information about," said Barbara Lawrence, who said the Pegasus passes under the Richland-Chambers Reservoir, where she lives on the south shore. "Information is very hard to come by ... if you're just an average person going about your life, you know nothing [about the Pegasus]. But you should know about it, because it affects you."
Colorado's tough, new air pollution rules for the oil and gas industry were approved only a month ago but they're already making an impact in Texas, where lawmakers and energy companies have long resisted tightening air standards.
Several companies have approached the nonprofit Environmental Defense Fund and expressed interest in discussing whether Colorado's rules make sense for Texas, according to Jim Marston, a vice president at EDF. Marston didn't name the companies.
"The companies are often ahead of the Texas state government," said Marston, who works in the group's Austin office. "If some important industry leaders like the idea, it might move state government."
EDF played a leading role among the environmental organizations that helped craft the Colorado rules. Many energy companies also participated in the rule-making process, but only four of them—Anadarko Petroleum Corp., DCP Midstream, Encana Corp. and Noble Energy, Inc.—fully support the new regulations.
America's electric cars are better for the environment, but they share a dirty little secret.
The Chevy Volt, Nissan Leaf and Tesla Roadster all use a super greenhouse gas known as HFC 134a as the refrigerant for their air conditioners. The liquid coolant is so potent that when it leaks into the atmosphere it traps 1,400 times more heat than carbon dioxide over a 100-year time horizon.
For automakers and advocates of green transportation, it poses an uncomfortable truth: Vehicles touted as a solution to climate change carry a hairspray-sized canister loaded with a chemical that significantly contributes to warming of the earth's climate. As much as half of current HFC emissions, a small but fast-growing source of global warming pollution, come from leaks out of the air conditioners in cars.
Already a number of Chevrolet, Buick, GMC and Cadillac gas-powered cars use an alternative climate-friendlier coolant called HFO 1234yf, as carmakers confront growing pressure from environmentalists and as regulations are developed by governments. Climate experts say it's clear that all electric automakers should get on board soon. "It makes sense for electric vehicles to use [alternatives], and to reduce their overall global warming potential," said Don Anair, deputy director of the clean vehicles program at the Union of Concerned Scientists, a science advocacy group.
But among 16 EV models on America's roads, only two—Chevy's newest model of its all-electric Spark and the leaseable Honda Fit—have ditched the super greenhouse gas HFC 134a for the climate safe alternative so far.
Environmentalists who spent a month analyzing public comments on the Keystone XL linked more than half the pro-pipeline comments they examined to people in the oil industry. As the U.S. State Department considers whether to approve the project, the activists want those remarks to carry less weight than those written by people without a vested interest in the outcome.
Out of a random sample of more than 1,000 comments in support of the Keystone, the environmentalists connected about 60 percent of the commenters' names to oil and pipeline company employees, investors, lobbyists, attorneys and others working for the industry—all of whom could potentially benefit from the construction of the pipeline, the activists said. If built, the pipeline would carry diluted bitumen from Canada's tar sands region to the Texas Gulf Coast.
"We don't want to accuse anyone of wrongdoing ... but to me this raises a red flag," said Terra Friedrichs, a volunteer at the environmental group 350MA who led the analysis. 350MA is a Massachusetts grassroots organization that advocates for sustainable energy. It often collaborates with, but is not affiliated with the national group 350.org.
Regulations.gov, the website used to collect public comments, doesn't require people to disclose their names, nationalities, occupations or financial interests.
Florida, the most vulnerable state in the country to climate change, faces a key election this November that could have significant ramifications for its ability to cope with the challenge of rising seas and intensifying coastal storms.
If incumbent Tea Party-aligned Rick Scott is reelected governor, it is expected to mean four more years of inaction on global warming. His likely opponent, Democrat Charlie Crist, a former governor of Florida, is committed to aggressive climate action. Environmental groups, scientists and policy experts say that if Crist or another climate hawk wins, it would give the state at least a shot at staving off the worst effects of global warming.
"It is critically important that the governor of Florida take action on climate change," said Frank Jackalone, senior organizing manager of the Florida chapter of the Sierra Club. "Even if the [average] forecasts for sea level rise come true, much of the state will be in trouble, areas will be wiped out and communities evacuated."
Florida is widely seen as America's ground zero for global warming because the majority of its population and economy is concentrated along low-elevation oceanfront.
New York regulators are requiring the state's biggest electric utility to armor the grid against all sorts of sweeping global warming impacts that could black out the nation's financial capital and disrupt services like cell phone networks and water and gasoline supplies.
The Feb. 20 ruling mandates Con Edison to carry out an immediate and comprehensive assessment of climate risks to its power grid, a lifeline of New York's economy. The utility must factor the data into all of its long-term planning, construction and budget decisions—and also use new flood maps that put much more of New York in vulnerable flood zones.
The ruling by the New York Public Service Commission is "a recognition that something has to be done to make the system withstand what appears to be the 'new normal,'" said Robert Thormeyer, a spokesman for the National Association of Regulatory Utility Commissioners (NARUC) who was not involved in the New York case. "They're taking a holistic approach to looking at how we can fit [climate change] into our everyday planning."
