How La Niña will shape heat and hurricanes this year

“The periodic swings between El Niño and La Niña, collectively known as the El Niño Southern Oscillation (ENSO), is a natural phenomenon cycling every three to seven years. Over the past year, the El Niño also synced with other natural patterns like the warm phase of the Atlantic Ocean’s temperature cycle, driving thermometers up further. But humanity’s relentless injection of heat-trapping gases into the atmosphere is pushing these changes to greater extremes.”

Red States Are Trying To Fight The World On Climate

“State Rep. Jeff Hoverson didn’t want anyone getting in the way of using fossil fuels in North Dakota. Not the United Nations. Not international nonprofits. Certainly not the Intergovernmental Panel on Climate Change. So he made a law to stop them. In March, the North Dakota legislature passed a bill that Hoverson co-authored with a state senator. It’s short, sweet and to the point: “A climate control-related regulation of an international organization, either directly through the organization or indirectly through law or regulation, is not enforceable on this state.”
Hoverson told me he isn’t sure what that will mean the next time the federal government wants to sign a climate treaty. Frankly, he’d prefer the feds not have that kind of power, anyway. But while his law stands out for the scope of its ambitions, it’s not exactly an outlier in its spirit. Across the country, bills pushing back against climate policy have been a trend this legislative session, with multiple states proposing — and passing — laws that would undermine efforts to limit greenhouse gas emissions.

Some of the laws aim to support the oil and gas industry in various ways, such as a bill in Indiana that amends clean-energy incentives for utility companies to include building natural-gas power plants as long as they can be said to displace coal, or another in Kentucky barring conservation easements in the state from infringing on the activities of oil and gas industries. Others have taken the form of preemption laws, barring cities and other regional governments from setting more stringent environmental regulations than the surrounding state. This includes laws preventing bans on gas stoves and requiring municipalities to include natural gas as a source of clean energy, as well as bills that would prevent them from banning the use of certain refrigerants before the federal government does.

None of this is exactly good Earth Day tidings. And, more importantly, this legislation highlights what a mess American climate policy is. These laws pit different branches of government against each other, roll back some environmental protections established in legislation of years’ past and, in the case of North Dakota, create laws to prevent things that are not currently happening and likely wouldn’t be enforceable if they did. Meanwhile, plenty of other states are introducing and often passing bills that do directly or indirectly reduce greenhouse gas emissions. The result is that predicting the near-term future of environmental regulation in this country is really hard. And that, economists say, can end up making it more expensive — and less appealing — to reduce emissions.”

Is the ‘Climate Time-Bomb’ Really Ticking Toward Imminent Catastrophe?

“What is the supposed looming climate catastrophe? Exceeding the threshold in which global average temperature rises 1.5 degrees Celsius above the 1850-1900 baseline. That threshold was established in the 2015 Paris Climate Change Agreement, which aims to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.” In order to have a 50/50 chance of achieving that goal, the new report calculates humanity must cut its greenhouse gas emissions (chiefly carbon dioxide) basically in half by 2030. Secretary-General Guterres asserted that the report shows that “the 1.5-degree limit is achievable.”
Will humanity inevitably suffer a catastrophic fall if we go over the supposed 1.5 degrees Celsius climatic cliff in 2030? No”

“It is the case that the world’s average temperature is about 1.1 degrees Celsius higher than it was between 1850 and 1900. The bulk of that temperature increase largely stems from burning fossil fuels that have loaded up the atmosphere with extra heat-trapping carbon dioxide. Atmospheric carbon dioxide stood at about 285 parts per million around 1850, rising to about 316 ppm by 1958 and is now at 420 ppm.

The report states that the evidence has “strengthened” that man-made global warming is responsible for observed changes in extremes such as heat waves, heavy precipitation, droughts, and tropical cyclones. Recent studies do show that the intensity, frequency, and duration of heat waves have increased since the 1950s and that the frequency of heavy rainfall events has also risen. On the other hand, clear evidence for changes in global trends in meteorological drought is lacking and global tropical cyclone accumulated energy (a measure of the combined duration and strength of tropical cyclones) is not increasing.”

“the report does not put a dollar figure on the losses that are projected to result from unmitigated climate change. Perhaps, as the report asserts, that is because “cost-benefit analysis remains limited in its ability to represent all avoided damages from climate change (high confidence).” Still, the report does note, “Even without accounting for all the benefits of avoiding potential damages the global economic and social benefit of limiting global warming to 2°C exceeds the cost of mitigation in most of the assessed literature (medium confidence).” A discreet footnote observes, “The evidence is too limited to make a similar robust conclusion for limiting warming to 1.5°C.” So the costs of trying to keep temperatures from increasing by 1.5 degrees Celsius might be greater than the benefits?”

Europe is burning like it’s 2052

“One especially dangerous aspect of the current heat wave is how warm it’s been after sunset. The UK just broke its record for the hottest temperature recorded at night. In many parts of the world, nighttime temperatures are rising faster than daytime heat. This often leads to worse health problems because people find little relief as heat stress mounts.”

“Much of Europe remains haunted by the 2003 heat wave that killed more than 70,000 people. The good news is that natural disasters like heat waves are becoming less deadly around the world. Better forecasting and more tools to cope with heat have saved lives in Europe. But with disrupted travel, increasing hospital visits, and lost productivity, heat is still extracting a growing social and economic toll.”

It’s so hot in Europe that roads are literally buckling

“Part of the problem is that many buildings, highways, and other infrastructure in Europe are old and built with outdated temperature extremes in mind, said Mikhail Chester, an associate professor of engineering at Arizona State University. They simply can’t tolerate the new normal, he said. Hence things like railway fires in London.

Cities like Dubai and Phoenix, Arizona, in contrast, can withstand higher temperature extremes because their infrastructure was built more recently and with heat in mind. While these places may face issues related to water and energy usage, 100-degree weather isn’t as big of a problem for them, Chester said.”

“Air conditioning is relatively rare in most of northern Europe, especially compared to the United States. The same is true of the London Tube — only 40 percent of the train network has air conditioning, and authorities warned commuters in the British capital to carry water with them if they traveled.”

Biden heads into international climate negotiations with a weak hand

“The US has a singular responsibility to lead: It is second in global climate pollution after China, but far and away responsible for the largest share of cumulative emissions. Since 1850, the US has released a fifth of all carbon emissions, far ahead of every other country, according to an analysis by the research group Carbon Brief.

But US political polarization remains one of the biggest obstacles to global action. The US has never come to an international conference with a comprehensive climate agenda backed by Congress, mostly because Republican lawmakers have refused to negotiate on a serious action plan. So Democrats have banked on passing Biden’s climate plans in the Build Back Better agenda with a simple Senate majority. Their bet on reconciliation has put a good portion of Biden’s climate agenda in the hands of West Virginia Sen. Joe Manchin, who is personally invested in the coal industry.

Biden brings a mixed bag of promises to Glasgow. The administration does not have a signed, final law from Congress that backs up his words with billions of dollars in funding. What he has are ambitious promises of slashing pollution in half by 2030, quadrupling international aid, and helping countries adapt to the impacts of climate change. Most of that will depend on Congress following through, and a successful regulatory agenda that survives Supreme Court scrutiny.”

An “attack on American cities” is freezing climate action in its tracks

“While many answers to climate change require national and even international action, cities often have the unilateral power to craft local rules like building codes. But before the city of Tucson could even look at possible building reforms, the Republican-led state legislature took away its power to do so — by passing a state law that natural gas utilities are “not subject to further regulation by a municipality.”

Supporters of the Republican bill were trying to beat climate advocates to the punch and “preempt” restrictions on fossil fuels. “We wanted to get ahead of what we viewed as an economically damaging trend, and stop it before it could gain a foothold here,” says Garrick Taylor, a spokesperson for the Arizona Chamber of Commerce and Industry, one of the lobbying groups that supported the bill.

With those few lines of text, Arizona blocked a path for cleaning up a significant source of Tucson’s climate pollution — even as nations around the world are racing to transition to cleaner energy and slow disastrous climate change.”

“Arizona was the first of many US states where “localities are cut off at the knees, because they’re in states where lawmakers are hostile” to these kinds of climate regulations, says Sheila Foster, a Georgetown University professor who specializes in urban environmental law.

Interest groups for the natural gas industry, worried about losing energy customers, have now promoted bills in half the country to strip cities of basic powers to set greener building codes and help phase out fossil-fuel pollution. These “preemption” laws have swept through 20 state legislatures; three more states have bills pending this year.”

The US is inching closer to passing a game-changing climate policy

“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.”
