Current conditions: Tens of thousands of people are without power in the UK after Storm Darragh • A volcanic eruption of Mount Kanlaon in the Philippines triggered emergency evacuations • Red Flag fire warnings are in effect across Southern California as Santa Ana winds encounter dry weather.

THE TOP FIVE

1. Copernicus: 2024 will be hottest year on record

The EU’s Copernicus Climate Change Service confirmed what many experts have long anticipated: 2024 will almost certainly beat 2023 to become the hottest year on record. It will also be the first with an average temperature exceeding the 1.5 degrees Celsius threshold – in fact the average temperature for 2024 is likely to be close to 1.6C above pre-industrial averages.

Copernicus

Last month was the second warmest November on record (surpassed only by last November). The global average temperature over the last 12 months through November was nearly 3 degrees Fahrenheit above the pre-industrial average and 1.3 degrees Fahrenheit above the more recent averages between 1991 and 2020. Sea surface temperatures also remain abnormally high.

2. World Bank raises $100 billion for poorest nations

The World Bank received $23.7 billion in increased contributions from donor countries to replenish its International Development Association, the lending arm dedicated to the world’s poorest and most vulnerable nations. That brings the total financing to $100 billion and marks “a significant moment for global development,” the bank said. African countries had hoped for more, given the strength of the dollar. Still, the development raises hopes for more climate resilience funding. The U.S. has pledged $4 billion to the IDA under President Biden, but that is expected to change under the incoming Trump administration.

3. Goldman Sachs pulls out of Net Zero Banking Alliance

In case you missed it: Goldman Sachs announced it is leaving the Net Zero Banking Alliance, a global climate coalition for banks. The group didn’t elaborate on the reasoning for the decision, but sources told Bloomberg it was due to mandatory reporting guidelines. “Firms have been struggling to adapt to a deluge of environmental, social, and governance requirements being enforced by regulators in key markets,” Bloomberg reported. Meanwhile, Republican lawmakers have been aggressively targeting ESG investment strategies. BlackRock and other investors are being sued by GOP-led states for allegedly breaching antitrust law in ESG investment. Goldman joined the NZBA in 2021. The coalition asks members to set interim five-year targets toward a goal of net zero financed emissions by 2050.

4. Global aridity crisis worsens

Over the last 30 years, large swathes of land that were once lush and humid have dried out, becoming too arid to sufficiently support robust ecosystems, according to a new report on global aridity from the UN Convention to Combat Desertification. The study found that more than 75% of all land on Earth has become drier over the last three decades, and that during that time, drylands expanded by an area the size of the Australian continent to cover 40% of all the global land (excluding Antarctica). This is a very bad trend. Aridity is different from drought. While drought eventually recedes, aridity is “an unrelenting menace,” leading to land degradation, water scarcity, biodiversity decline, crop losses, and large-scale human migration. Human-caused climate change is the main cause of the aridity crisis. “If the world fails in efforts to curb greenhouse gas emissions,” the UN warned, “another 3% of the world’s humid areas are projected to transform into drylands by the end of this century.”

5. Trump considering nixing plans to electrify USPS fleet

President-elect Trump’s transition team reportedly wants to kill the Postal Service’s plans to electrify its delivery trucks. The team is examining ways to cancel the various contracts between USPS and providers like Ford and Oshkosh for tens of thousands of EVs, as well as charging stations. As Heatmap’s Jeva Lange reported recently, the small trucks driven by most local mail carriers get an abysmal 9 miles per gallon, “burning fuel by the tankful and spewing emissions as they go about their appointed rounds.”

THE KICKER

Rules designed to protect whales from deadly collisions with ships are in place across just 7% of whale movement hotspots.

New York’s Largest Battery Project Has Been Canceled

Fullmark Energy quietly shuttered Swiftsure, a planned 650-megawatt energy storage system on Staten Island.

The biggest battery project in New York has been canceled in a major victory for the nascent nationwide grassroots movement against energy storage development.

It’s still a mystery why exactly the developer of Staten Island’s Swiftsure project, Fullmark Energy (formerly known as Hecate), pulled the plug. We do know a few key details: First, Fullmark did not announce publicly that it was killing the project, instead quietly submitting a short, one-page withdrawal letter to the New York State Department of Public Service. That letter, which is publicly available, is dated August 18 of this year, meaning that the move formally occurred two months ago. Still, nobody in Staten Island seems to have known until late Friday afternoon when local publication SI Advance first reported the withdrawal.

Current conditions: Hurricane Melissa exploded in intensity over the warm Caribbean waters and has now strengthened into a major storm, potentially slamming into Cuba, the Dominican Republic, Haiti, and Jamaica as a Category 5 in the coming days • The Northeast is bracing for a potential nor’easter, which will be followed by a plunge in temperatures of as much as 15 degrees Fahrenheit lower than average • The northern Australian town of Julia Creek saw temperatures soar as high as 106 degrees.

THE TOP FIVE

1. Exxon sued California

Exxon Mobil filed a lawsuit against California late Friday on the grounds that two landmark new climate laws violate the oil giant’s free speech rights, The New York Times reported. The two laws would require thousands of large companies doing business in the state to calculate and report the greenhouse gas pollution created by the use of their products, so-called Scope 3 emissions. “The statutes compel Exxon Mobil to trumpet California’s preferred message even though Exxon Mobil believes the speech is misleading and misguided,” Exxon complained through its lawyers. California Governor Gavin Newsom’s office said the statutes “have already been upheld in court and we continue to have confidence in them.” He condemned the lawsuit, calling it “truly shocking that one of the biggest polluters on the planet would be opposed to transparency.”

How to Live in a Fire-Scarred World

The question isn’t whether the flames will come — it’s when, and what it will take to recover.

In the two decades following the turn of the millennium, wildfires came within three miles of an estimated 21.8 million Americans’ homes. That number — which has no doubt grown substantially in the five years since — represents about 6% of the nation’s population, including the survivors of some of the deadliest and most destructive fires in the country’s history. But it also includes millions of stories that never made headlines.

For every Paradise, California, and Lahaina, Hawaii, there were also dozens of uneventful evacuations, in which regular people attempted to navigate the confusing jargon of government notices and warnings. Others lost their homes in fires that were too insignificant to meet the thresholds for federal aid. And there are countless others who have decided, after too many close calls, to move somewhere else.

By any metric, costly, catastrophic, and increasingly urban wildfires are on the rise. Nearly a third of the U.S. population, however, lives in a county with a high or very high risk of wildfire, including over 60% of the counties in the West. But the shape of the recovery from those disasters in the weeks and months that follow is often that of a maze, featuring heart-rending decisions and forced hands. Understanding wildfire recovery is critical, though, for when the next disaster follows — which is why we’ve set out to explore the topic in depth.
