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,” explainedCarbon 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.

    Trump Can’t Save Coal From Natural Gas

    The president’s executive order is already too late to save at least one Arizona plant.

    The Trump administration is trying to save coal again. But despite the president’s seemingly forceful actions, there’s little indication he’ll be any more successful at it this time than he was the last time around.

    Backed by coal miners in hard hats and high visibility jackets, Trump on Tuesday announced a series of executive orders meant to boost “beautiful, clean coal.” The orders lift barriers to extracting coal on public lands, ask the Department of Energy to consider metallurgical coal a critical mineral, push out compliance with some air quality rules by two years, instruct the Department of Energy to use emergency authorities to keep coal plants open, and direct theattorney general to go after state climate laws that Trump claimed “discriminate” against greenhouse gas-emitting energy sources like coal.

    What’s not clear is how much these orders will boost the coal industry, let alone save it. It’s not even clear whether the specific plant Trump said he was saving will burn coal again.

    Trump’s Tariffs Are Here, and Financial Markets Are in Turmoil

    Current conditions: States left flooded from recent severe storms are now facing freezing temperatures • Firefighters are battling blazes in Scotland due to unusually warm and dry weather • Hospitals in India are reporting a 25% rise in heat-related illnesses compared to last year. Yesterday the country’s northern state of Rajasthan reached 115 degrees Fahrenheit, about 13 degrees higher than seasonal norms.

    THE TOP FIVE

    1. Markets in turmoil as Trump’s new tariffs come into effect

    President Trump’s sweeping new tariffs came into effect at 12:01 a.m. on Wednesday, rattling the world’s markets and raising the risk of a global trade war. The levies, which include a 104% tariff on Chinese imports, triggered a mass sell-off in U.S. Treasury bonds, hiking yields as investors worry about a potential recession and flock to alternative safe-haven investments. The price of oil fell for the fifth day in a row to its lowest since 2021, with Brent futures at about $61 per barrel, well below the $65 level that oil producers need in order to turn a profit drilling new wells nationwide. As Heatmap’s Robinson Meyer explained recently, the tariffs are an outright catastrophe for the oil industry because they threaten a global downturn that would hurt oil demand at a time when oil cartel OPEC+ is increasing its output. Trump’s slate of tariffs will impact the cost of just about everything, from gasoline to e-bikes to LNG to cars. China imposed retaliatory tariffs, increasing them from 34% to 84% in response to the U.S. escalation. Meanwhile, the European Union will vote today on whether to impose its own retaliatory fees. European shares plummeted, as did Asian and Australian stocks.

    China’s industrial policy for clean energy has turned the country into a powerhouse of solar, wind, battery, and electric vehicle manufacturing.

    But long before the country’s factories moved global markets — and invited Trump’s self-destructive tariffs — the country implemented energy and technology policy to level up its domestic industry. How did those policies work? Which tools worked best? And if the United States needs to rebuild in the wake of Trump’s tariffs, what should this country learn?
