Saturday September 19th… Dear Diary. The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Current Account Of Trump’s Environmental Rollbacks Harming Efforts To Stem Global Warming In Light Of Ruth Bader Ginsberg’s Passing
Dear Diary. Last evening we learned of another great American icon’s passing during this terrible year when death seems to be stalking all of us. Ruth Bader Ginsburg tried to live through the year 2020 knowing that she was the last firewall preventing the U.S. Supreme Court from becoming totally conservative in nature My condolences and heart goes out to her family:
In our present form of government, should Green New Deal legislation get enacted, a conservative Supreme Court could potentially declare portions or all of it unconstitutional, so indeed those of us supporting climate mitigation are worried about RBG’s replacement.
So far, the Trump Administration has done an immense amount of damage be delaying global warming mitigation through some pretty bad policy. That could be compounded by another conservative Supreme Court pick, which could throw a big monkey wrench into anything Joe Biden’s Administration does should he become President. It’s time to once more see how much damage has been done. To do this let’s employ a recent New York Times article written this week:
The Trump administration has acted to repeal or weaken at least 100 environmental regulations over the past four years, including a number of Obama-era climate policies that Mr. Trump has said stifle businesses. The rollbacks include:
Fuel-economy standards: The Trump administration changed Obama-era rules that would have required new passenger cars, SUVs and pickup trucks sold in the United States to become less polluting over time. Instead of improving fleetwide fuel economy by 5 percent annually for model years 2021 through 2026, automakers will now have to improve just 1.5 percent per year.
The administration also revoked California’s authority to set its own tailpipe emissions standards and to mandate electric vehicles. California’s special right to set stricter automobile pollution limits than the federal government’s dates back to the Clean Air Act of 1970, and for years the state has required that automakers sell a certain amount of electric vehicles. As of September, 13 states and Washington, D.C., have formally adopted California’s policies and are challenging the administration’s decision in court.
Together, these vehicle rollbacks would have the largest effect on future emissions. New cars and trucks are expected to emit one billion more tons of carbon dioxide through 2035 than they would have if the cleaner vehicle rules had stayed in place. The rule changes could also lead to five million fewer electric cars sold over that span, the Rhodium Group, a research and consulting firm, estimated. The transportation sector is the largest source of greenhouse gas emissions for the United States.
Methane leaks from oil and gas operations: The Trump administration has also sought to revise or reverse two major Obama-era rules aimed at limiting leaks and intentional venting of methane, a powerful greenhouse gas. (In July, a federal judge blocked the rollback of one of these rules, concerning methane on public lands, but the administration is still pushing to repeal it.)
Methane is the primary ingredient in natural gas, but when it escapes into the atmosphere before being burned for energy, it can warm the planet 36 times as much as carbon dioxide does over a 100-year period. Several recent studies have found that more methane is leaking from oil and gas facilities than previously thought.
Under Mr. Trump, the Environmental Protection Agency also delayed regulations on methane leaks from landfills, another significant source of emissions. Methane is created when food and other waste decomposes under low-oxygen conditions. The Obama administration had issued rules to capture more of this methane from waste.
Regulations on hydrofluorocarbons, or HFCs: These potent greenhouse gases are used in air-conditioners, refrigeration and insulating foams. In 2017, the world’s nations agreed to phase out the use of HFCs in favor of alternatives less dangerous to the climate, but the Trump administration has not ratified that treaty and instead has proposed to roll back federal regulations curbing the use of HFCs in the United States. (The Rhodium Group’s analysis only looks at the effects of the regulatory rollbacks. Congress has pushed to adopt new policies that would slash HFC use, but those have not passed into law yet.)
Assuming these Trump administration policies go forward as planned and survive legal challenges, the United States will emit the equivalent of an extra 1.8 billion tons of carbon dioxide between now and 2035, the Rhodium Group estimated. That’s more than Germany, Britain and Canada together emitted from energy use in 2018, the latest year for which data is available.
Greenhouse gas emissions are the main driver of global warming, which is increasingly causing damage throughout the United States. More frequent flooding along the coasts, increased fire hazard in the West, worsening air quality, and fiercer heat waves have all been tied to rising global temperatures. If emissions are not reined in, scientists say, the damage will only deepen.
The new analysis looked at total emissions over the next 15 years because the impact of these rollbacks will grow over time, said Hannah Pitt, a senior analyst at the Rhodium Group. New cars and trucks sold today are expected to stay on the road for more than a decade, for example, which means they will steadily emit more carbon dioxide than they otherwise would have under more stringent rules.
The rollbacks measured here represent only a portion of the climate policies that the Trump administration has sought to reverse. President Trump has also moved to withdraw the United States from the Paris climate change agreement, an international accord to reduce greenhouse gas emissions, and has pushed to open up new federal lands for oil and gas development. The Energy Department also plans to change federal rules that would have required more efficient light bulbs. But it is difficult to quantify the full effects of many of those policies, and they were not included in the Rhodium Group analysis.
President Trump has also repealed and replaced the Obama-era Clean Power Plan, which aimed to push states to reduce emissions from coal-fired power plants and shift to cleaner alternatives like natural gas or renewable energy. It is unclear what effects this move will ultimately have: Many states have been retiring coal plants and shifting to cleaner alternatives recently — because of the falling cost of natural gas, wind and solar power — and were already beating the targets set by the Obama-era rule.
The coronavirus pandemic has injected an extra dose of uncertainty into this analysis. As states locked down, transportation emissions fell as people drove fewer miles. The Rhodium Group analysis assumes that U.S. economic activity will largely recover in the years ahead, and there are already signs of a rebound. But if, for instance, vehicle traffic remains depressed for years to come, then the fuel-economy rollbacks will have a somewhat smaller effect on emissions.
The Trump administration’s rule changes have not halted all efforts to address climate change nationwide. Even as the federal government retreats from regulating emissions, many states and cities are acting on their own to clean up pollution from power plants and buildings. California has struck an agreement with five large automakers — Ford, Honda, BMW, Volkswagen and Volvo — to stick to Obama-era fuel-economy standards, which will partly blunt the effect of Mr. Trump’s rollbacks. States like Colorado and New Mexico are creating policies to curb methane leaks, and at least 16 states have announced plans to cut the use of HFCs.
Overall, planet-warming emissions in the United States are expected to be lower at the end of Mr. Trump’s first term than they were when he took office, in part because of action by states and cities. But the climate rollbacks mean that emissions will still be higher than they would have been if the rules had stayed in place, at a time when scientists and environmentalists say they will need to fall even faster to avert the worst consequences of global warming.
Perhaps the biggest uncertainty in gauging the climate effects of the Trump administration is the upcoming election. If, for instance, former Vice President Joseph R. Biden Jr. wins the White House and swiftly moves to reinstate new rules on vehicles, methane and HFCs — or puts in place even more sweeping policies to cut emissions, as he has pledged — the effect of Mr. Trump’s changes could, in theory, be undone. If Mr. Trump wins re-election, however, many of the rollbacks are more likely to stay in place.
In conclusion, the next four months up until Joe Biden’s inauguration may very well be the most important in association with our environment and climate in the next few million years, adding the Supreme Court into the mix. We stand on the precipice of oblivion depending on what we as a people decide to do with climate policy for the rest if this decade and beyond. This is not hyperbole it an exaggeration…literally.
