“The backlog of forest restoration projects suggests that there are issues on public lands that really need to be addressed, but that is not an argument for creating a vast new federal bureaucracy with as many as 1.5 million government employees.”

“Bolstered with better data and even clearer trends, they’re no longer reluctant to point the finger back at humanity for worsening these calamities. In the latest report from the Intergovernmental Panel on Climate Change (IPCC), a team of leading researchers convened by the United Nations presented some of the most robust research that connects the dots. It shows how some greater weather extremes can be traced back to rising average temperatures, which in turn stem from emissions of greenhouse gases, mainly from countries and corporations burning fossil fuels.
“On a case-by-case basis, scientists can now quantify the contribution of human influences to the magnitude and probability of many extreme events,” according to the report.”
“In the public conversation about climate change, methane has gotten too little attention for too long. Many people may be unaware that humans have been spewing a greenhouse gas that’s even more potent than carbon dioxide into the atmosphere at a rate not seen in at least 800,000 years. It harms air quality and comes from sources as varied as oil and gas pipelines to landfills and cows. But methane and other greenhouse gases, including hydroflurocarbons, ozone, nitrogen dioxides, and sulfur oxides, are finally getting the attention they deserve — thanks largely to advances in the science.
Until the past few years, methane’s relative obscurity made sense. Carbon dioxide (CO2) is by far the largest contributor to climate change, and it comes from recognizable fossil fuel sources such as car tailpipes, coal smokestacks, and burning gas and oil. The most troubling part is that it sticks around in the atmosphere for hundreds of years, making climate change not just a problem for us now, but generations well into the future. Carbon is now embedded in our language, from “carbon footprint” to “zero-carbon lifestyle.””
…
“Even though methane is not nearly as well understood as carbon, it’s playing an enormous role in the climate crisis. It’s at least 80 times as effective at trapping heat than carbon in a 20-year period, but starts to dissipate in the atmosphere in a matter of years. If this is the “decisive decade” to take action, as the Biden administration has said, then a methane strategy has to be at the center of any policy for tackling global warming.
Methane could mean the difference between a rapidly warming planet changing too quickly and drastically for humanity to handle, and buying the planet some much-needed time to get a handle on the longer-term problem of fossil fuels and carbon pollution.”
…
“Identifying the millions of sources of methane around the globe isn’t so simple. Cattle release methane, and so does decomposing organic material. All the food waste that goes into landfills release methane. And natural gas is almost entirely methane.
If you’ve heard politicians call natural gas a “bridge fuel,” what they mean is that natural gas emits less carbon dioxide than coal. It’s wrong to call it clean, because burning methane still releases carbon — and methane that escapes without burning is a powerful warmer.”
…
“Environmental Defense Fund, which has commissioned flights to monitor methane over Texas oil and gas fields, has found that oil fields in the US are leaking 60 percent more methane than the Environmental Protection Agency estimates. University of Michigan scientist Eric Kort found methane spewing from offshore wells at far higher rates than previously understood. The environmental group Earthworks, using expensive, on-the-ground camera equipment, helped track down some sites that were repeat offenders of venting methane into the atmosphere.
The scientific papers have mounted: Since 2013, at least 45 scientific papers have highlighted the disproportionate role of oil and gas operations, according to a review by the advocacy group Climate Nexus.”
…
“There’s widespread agreement, even from some in the fossil fuel industry, that the place to start is tackling leaks. This will get easier as scientists gather better data about where methane is leaking. From the industry’s perspective, companies are losing product and dollars.”
…
“Fractions of degrees could translate into wild swings in extreme weather, or tipping points we don’t even fully understand. In the effort to prevent climate catastrophe, methane will count tremendously.”

“A time when the United States runs mostly on wind- and solar-powered electricity could be a reality in only a few years. It wouldn’t require any scientific breakthroughs or technological leaps for clean energy to overtake coal and natural gas, which still dominate 60 percent of the US power sector. What it would take to challenge a century of fossil-fuel dominance in record-breaking time is one sweeping, underappreciated policy: a clean electricity standard.”
…
“A clean electricity standard is a bit of a misnomer because the actual policy being discussed is even more boring-sounding: a clean electricity payment program that pays utilities to clean up their act and fine them for missing deadlines. Still, this approach could effectively double the amount of wind and solar on the market, moving the nation toward roughly 80 percent renewable sources of electricity by 2030, and within reach of 100 percent clean electricity by 2035. It’s critical to getting the US halfway to Biden’s pledge under the Paris climate agreement.”
…
“Two of the biggest ways Americans contribute to climate change is in their transportation and electricity usage. You might cut your carbon footprint by making your home more efficient, installing a solar panel, and even buying an electric car — and the power that flows from your outlet is a lot cleaner than it was a decade ago. But coal and natural gas, more often than not, are still the status quo. This reality limits the impact of well-meaning actions: A coal-fired power plant may be charging your Tesla, and gas might be powering your office’s air conditioning.”
…
“The biggest short-term benefits aren’t even about climate change. Continuing to cut coal also slashes the country’s air pollution, like the ozone and particulates that damage people’s lungs and hearts. These gains would easily dwarf what the Environmental Protection Agency has accomplished under previous presidents because it would close more coal-powered plants than even President Barack Obama’s most effective environmental regulation, the mercury and air toxins rule.
And then there are the lives saved, according to research from Harvard University: By 2030, the policy would save 9,200 lives because of the sudden cut in air pollution. Over the next 30 years, that number grows to 317,500 lives saved.”
“The Intergovernmental Panel on Climate Change (IPCC), the United Nations’ climate science research group, concluded in a major report that it is “unequivocal” that humans have warmed the skies, waters, and lands, and that “widespread and rapid changes” have already occurred in every inhabited region across the globe. Many of these changes are irreversible within our lifetimes.
This is the first report of its kind in eight years, and a lot has changed. Scientists have backed away from many of the best-case scenarios. They’re more confident than ever that human-caused climate change is already worsening deadly weather events, from flooding to heat waves. And they’re investigating culprits of climate change that warm the planet even more than carbon dioxide.”
…
“The goal of these reports is to compile the best available science and create a solid foundation for decision-makers to act, whether that’s to invest in clean energy, relocate people from high-risk areas, or help the most vulnerable places cope with unavoidable impacts.”
…
“While researchers have better answers now on some fronts, they are also blunt about the things they still don’t know, which could have huge effects on the livability of the planet. Certain tipping points, feedbacks, and currently unappreciated mechanisms could further tilt the climate out of balance in ways that are hard to predict.”
…
“in the eight years since the last comprehensive IPCC report and the six years since the Paris accords, humanity’s output of heat-trapping gases has only grown. Even with a dip in emissions stemming from the Covid-19 pandemic, carbon dioxide concentrations in the atmosphere reached a record high this year, topping 419 parts per million, a level the planet has not seen for at least 2 million years.
This rise in emissions has given scientists unprecedented opportunities to study climate change in real time. Alongside improvements in computer simulations, measurement technology, laboratory experiments, and historical records, scientists have gained far more insight to, and confidence in, humanity’s role in cranking up the planet’s thermostat.”
…
“According to the report, it now seems impossible that the world will get lucky and warming will somehow stay within the Paris agreement targets without massive action to limit emissions, starting right away.”

“Unabated man-made climate change would likely become a significant problem for humanity by the end of this century. But the more plausible emissions scenarios suggest it is eminently possible to grow the world’s economy while keeping global temperatures below catastrophic thresholds, by gradually transitioning from fossil fuels.”
“Whether the United States can get to net-zero emissions by 2050 hinges hugely on our love of cars: They’re the dominant mode of transportation in America — ridership on trains, buses, and other public transit pales in comparison.
Other transportation options are limited, and cars are ingrained in American culture. This makes switching to electric vehicles an attractive way to decarbonize. But in order to encourage more people to buy electric vehicles (EVs), the US needs a better charging station infrastructure.”
…
“Because gas stations are the most common method of refueling cars in the United States, powering up electric vehicles might call to mind clusters of charging stations next to convenience stores next to a highway or road.
But the two modes of powering up are fundamentally different. For one thing, driving into a gas station, filling up, and driving out typically takes just a few minutes.
The fastest EV charging stations — like DC Fast — on the other hand, take up to 20 minutes to charge enough to power the vehicle to a 60- to 80-mile range. Some state and city planners and EV experts are working on putting charging stations outside of restaurants, grocery stores, and shops, so that people can go off and eat a meal or shop while their car is refueling.
“Most charging, we would hope and expect, is happening while people are doing something else,” said Eric Wood, a research engineer at the National Renewable Energy Laboratory’s Center for Integrated Mobility Sciences. “The idea that charging is happening slowly can be convenient for the driver as well as the grid.””
…
“Home charging may be the most convenient, but home charging is also typically relegated to higher-income people who can actually afford to charge from within their home. For lower-income people who don’t have a garage or a dedicated parking spot with easy access to a charger, the logistics of charging at home become much more complicated.”
