Earth Spent 12 Months Above the 1.5C Warming Limit

Current conditions: Forest fires are under control in Chile’s Viña del Mar, but continue to burn in other parts of the country • Los Angeles recorded at least 475 mudslides due to the atmospheric river • It’s 75 degrees Fahrenheit and sunny in Naples, Florida, where a 9-acre beachfront retreat just hit the housing market for a record-breaking $295 million.

THE TOP FIVE

1. World exceeds 1.5C in warming for a full year

Temperatures on Earth have been more than 1.5 degrees Celsius above pre-industrial levels for a year, according to the European Union’s Copernicus Climate Change Service (C3S). New data shows that from February 2023 through January 2024, the average global temperature was 1.52 degrees Celsius higher than the 1850-1900 baseline. Last month was also the warmest January ever recorded, C3S confirmed. In 2015, 196 nations adopted the legally binding Paris Agreement with the long-term goal of limiting the global temperature increase to well below 2 degrees Celsius, and ideally below 1.5 degrees. A one-year breach doesn’t mean the target is bust, because it “refers to long-term warming – the IPCC uses 20 to 30 years – not annual temperatures that include the short-term influence of natural fluctuations in the climate, such as El Niño,” explained Carbon Brief. However, some experts, including the new chief of the World Meteorological Organization, believe the rate of warming is speeding up.

2. New EPA air pollution rules could save thousands of lives

In case you missed it: The Environmental Protection Agency (EPA) rolled out new air pollution rules yesterday, cracking down on dangerous particulate matter. Previously, the EPA’s annual standard for concentrations of particulate matter was 12 micrograms per cubic meter (µg/m3). Based on epidemiological research showing that this standard did not adequately protect public health, the agency has now lowered the standard to 9 µg/m3. The rules are expected to prevent 4,500 premature deaths per year by 2032. The EPA also updated its Air Quality Index in conjunction with the new rules, which could mean that even as the air gets cleaner, you might get more air quality alerts, reported Heatmap’s Emily Pontecorvo.

3. Monarch butterfly numbers drop sharply

Heat, drought, and pesticides and herbicides are taking a toll on the monarch butterfly population. Numbers of the iconic orange butterflies in Mexico, where they spend the winter, fell by 59% this year to their second lowest level ever recorded, The Associated Press reported. Extreme weather, logging, and chemical treatments are all hurting the insects’ natural habitat and killing the milkweed plant on which they lay their eggs. “It has a lot to do with climate change,” said Gloria Tavera, director of Mexico’s Commission for National Protected Areas. The monarchs’ migration path is the longest of any insect species known to science: They winter in Mexico and then head north to Canada. No single butterfly survives the entire trek; instead their offspring finish it for them, before turning around and heading back to Mexico to start the process over again.

  • 4. Orsted had a no good, very bad year

    Danish energy developer Orsted said yesterday that it had lost a ton of money on its experiment trying to build wind farms in the United States, and planned to take on way less risk going forward. The figures are pretty grim, as Heatmap’s Matthew Zeitlin reported: Orsted had 9.6 billion Danish kroner worth of fees (about $1.4 billion) related to one New Jersey project, Ocean Wind 1, and had booked $4 billion of losses, most of which were due to Ocean Wind 1’s cancellation. Overall, it reported a loss of almost $3 billion in 2023. Orsted also said it was pulling out of Norway, Spain, and Portugal. In a call with analysts, the company’s chief executive Mads Nipper said that Orsted will spend far less money on projects before making the final approval to go forward with construction.

    5. Study suggests thinking about future generations moves people to support climate policy

    Convincing people to change their habits and beliefs is very hard, but when it comes to the climate crisis, widespread behavioral shifts are essential. A new “global megastudy” of more than 59,000 participants across 63 countries attempted to figure out which “interventions” can be most effective at shifting beliefs and getting people to support climate policy. The results, published in Science Advances, show that the act of writing a letter to future generations was “one of the top interventions tested.” Participants had to pen a note to a hypothetical child who will be turning 30 in the year 2055, detailing what they’re doing now to help keep the planet healthy. This exercise was the most effective intervention at nudging people toward supporting climate mitigation policies.

    “Ice Bed,” by Nima Sarikhani, is the winner of the 2023 Wildlife Photographer of the Year 59 People's Choice Award. The picture shows a male polar bear drifting off to sleep on a small iceberg off the Svalbard archipelago. “I hope that this photograph also inspires hope,” Sarikhani said. “There is still time to fix the mess we have caused.” The competition is developed and produced by the Natural History Museum, London.

    The EPA’s Backdoor Move to Hobble the Carbon Capture Industry

    Why killing a government climate database could essentially gut a tax credit

    The Trump administration’s bid to end an Environmental Protection Agency program may essentially block any company — even an oil firm — from accessing federal subsidies for capturing carbon or producing hydrogen fuel.

    On Friday, the Environmental Protection Agency proposed that it would stop collecting and publishing greenhouse gas emissions data from thousands of refineries, power plants, and factories across the country.

    The ‘Buffer’ That Can Protect a Town from Wildfires

    Paradise, California, is snatching up high-risk properties to create a defensive perimeter and prevent the town from burning again.

    The 2018 Camp Fire was the deadliest wildfire in California’s history, wiping out 90% of the structures in the mountain town of Paradise and killing at least 85 people in a matter of hours. Investigations afterward found that Paradise’s town planners had ignored warnings of the fire risk to its residents and forgone common-sense preparations that would have saved lives. In the years since, the Camp Fire has consequently become a cautionary tale for similar communities in high-risk wildfire areas — places like Chinese Camp, a small historic landmark in the Sierra Nevada foothills that dramatically burned to the ground last week as part of the nearly 14,000-acre TCU September Lightning Complex.

    More recently, Paradise has also become a model for how a town can rebuild wisely after a wildfire. At least some of that is due to the work of Dan Efseaff, the director of the Paradise Recreation and Park District, who has launched a program to identify and acquire some of the highest-risk, hardest-to-access properties in the Camp Fire burn scar. Though he has a limited total operating budget of around $5.5 million and relies heavily on the charity of local property owners (he’s currently in the process of applying for a $15 million grant with a $5 million match for the program) Efseaff has nevertheless managed to build the beginning of a defensible buffer of managed parkland around Paradise that could potentially buy the town time in the case of a future wildfire.

    How the Tax Bill Is Empowering Anti-Renewables Activists

    A war of attrition is now turning in opponents’ favor.

    A solar developer’s defeat in Massachusetts last week reveals just how much stronger project opponents are on the battlefield after the de facto repeal of the Inflation Reduction Act.

    Last week, solar developer PureSky pulled five projects under development around the western Massachusetts town of Shutesbury. PureSky’s facilities had been in the works for years and would together represent what the developer has claimed would be one of the state’s largest solar projects thus far. In a statement, the company laid blame on “broader policy and regulatory headwinds,” including the state’s existing renewables incentives not keeping pace with rising costs and “federal policy updates,” which PureSky said were “making it harder to finance projects like those proposed near Shutesbury.”
