AM Briefing: Insects in Decline

On the troubling rise of self-pollination, Chinese EV tariffs, and speed limits

AM Briefing: Insects in Decline

Current conditions: Southern California remains at risk of flooding and may even see some waterspouts or tornadoes • A wildfire is burning out of control in Perth, in Australia • It's the shortest day of the year in the Northern Hemisphere.

THE TOP FIVE

1. U.S. may hike tariffs on Chinese EVs

The Biden administration is reportedly considering raising tariffs on electric vehicles made in China, which tend to run cheaper than those made in the U.S. The move would be an attempt to “bolster the U.S. clean energy industry,” explains The Wall Street Journal. Chinese EVs are already subject to a 25% tariff. While an increase wouldn’t mean much in the immediate term for most Americans, it would put added strain on relations with China, which are already tense. Global markets are facing a glut of cheap Chinese clean-energy products, and the administration is reportedly also considering higher levies on solar products and EV battery packs, the Journal reports.

2. Study suggests some plants are evolving to not need pollinators

Wildflowers may be evolving to rely less on pollinators in order to reproduce as insect numbers decline. A new study published in the journal New Phytologist looked at flowering plants that grow in farmland near Paris and found they have become smaller and now produce less nectar than they would have 20 to 30 years ago. “Our study shows that pansies are evolving to give up on their pollinators,” says Pierre-Olivier Cheptou, one of the study’s authors. “They are evolving towards self-pollination, where each plant reproduces with itself, which works in the short term but may well limit their capacity to adapt to future environmental changes.” While the study “demonstrates that plant mating systems can evolve rapidly ... in the face of ongoing environmental changes,” the authors say, it paints a troubling picture of a symbiotic relationship in a spiral: As insect populations suffer from loss of habitat and overuse of pesticides, plants begin to rely on them less and produce less nectar, exacerbating their decline.

3. U.S. completes auction for Gulf drilling rights

A U.S. auction of oil drilling rights in the Gulf of Mexico went ahead yesterday. This is the last auction until 2025. Here are a few key numbers:

  • 72.7 million – acres that were up for bidding, including 6 million acres considered habitat for the endangered Rice's whale.
  • $382 million – amount raised in the auction, the highest of any federal offshore oil and gas lease sale since 2015, according to Reuters.
  • $88.2 million – highest amount offered, from Hess, for 20 successful bids.
  • 3 – drilling rights auctions the Interior Department will hold over the next five years, the minimum required to comply with the Inflation Reduction Act. It represents “the smallest offshore oil program in U.S. history.”
  • 47 – auctions over five years that were proposed by the Trump administration.
  • 1.1 million – gallons of oil estimated to have spilled into the Gulf from a leak detected last month, the largest Gulf spill since Deepwater Horizon.
  • 8 – days since the U.S. and nearly 200 other nations agreed at COP28 to transition away from fossil fuels.
  • 21 – percent of the world’s oil produced by America in 2022.

4. Orsted commits to building world’s largest offshore wind farm

Danish energy giant Orsted plans to go ahead with building the world’s largest offshore wind farm, reports the Financial Times. The 2.9 gigawatt Hornsea 3 project is located in the North Sea. It will cost £8 billion (about $10 billion) and represents Orsted’s single biggest investment decision. Once finished in 2027, the project will power 3.3 million homes. Last month Orsted cancelled two major U.S. offshore wind projects and took a $4 billion writedown as a result. The Hornsea 3 investment shows “the offshore wind industry is picking back up, after a crisis year,” concludes Priscila Azevedo Rocha at Bloomberg.

  • 5. Cities are lowering their speed limits

    Speed limits in some major U.S. cities are dropping, Yale Climate Connections reports. This is a “win for the climate” because slower vehicle speeds make for safer city streets, which could nudge people more toward less polluting modes of transportation, like walking or cycling. Seattle, Denver, Minneapolis, Hoboken, and Washington, D.C., have all lowered their speed limits, according to Yale Climate Connections. “Safety and environmental goals go together. They’re inevitably interlinked,” says Venu Nemani, the chief safety officer of the Seattle Department of Transportation.

    THE KICKER

    A recent White House briefing says more than one million EVs have been sold in the U.S. in 2023 — “three years ahead of the projections made earlier this year and 18 years ahead of the projections made in the beginning of 2021.”

    The Zeal of the Inverter

    U.S. Weighs Banning Foreign Inverters

    Current conditions: As a dangerous heat dome settles over the central and eastern United States, evapotranspirate, or “sweat,” from corn has rendered Iowa and Illinois more humid than the Amazon • Temperatures just topped 100 degrees Fahrenheit in Zagreb, where intense thunderstorms are deluging the Croatian capital today • Hanoi, Vietnam, is in the midst of a week of severe thunderstorms.

    THE TOP FIVE

    1. U.S. weighs banning foreign inverters

    In May 2025, Reuters broke news that the U.S. government had discovered rogue communications devices in the inverters that converted the direct current flow of electricity from certain Chinese-made solar panels to the alternating current needed to patch the generators onto the grid. Now, more than a year later, Reuters is out with another scoop indicating that the Trump administration is preparing to slap new import restrictions on foreign-made inverters, particularly from China. The prohibition being drafted by the Federal Communications Commission would apply to all new foreign models of inverters and could be published as early as this year, unnamed sources told the newswire.

    Congress Never Meant to Design This

    The Supreme Court keeps changing the terms of the deal between the legislative branch and the executive.

    Congress Never Meant to Design This

    The Supreme Court ended its 2025–2026 term today, issuing a flurry of rulings on its most controversial cases. Most significantly, it rejected President Trump’s attempt to overturn birthright citizenship, preserving the 14th Amendment as it has been read for more than a century. It also struck down restrictions on how much political parties can spend in coordination with candidates — a change that could shape political strategies in November’s midterm election.

    But I suspect that the year’s most important ruling for energy and climate policy came … yesterday. In a 6-3 ruling, the court’s conservative majority allowed President Trump to fire the commissioners of independent agencies without cause. Although the case concerned the Federal Trade Commission, it will matter for every independent agency that governs energy and climate policy.

    My Extremely Hot European Vacation

    I decided to go to Italy in June with my husband, my 9-month-old daughter, and my 69-year-old father. What could go wrong?

    The start of a vacation really begins 10 days before departure, when your arrival date first appears on your weather app. Like the turning over of a tarot card, it is this initial forecast that hints at the potential character of your trip — whether your beach vacation might be ruined by rain, or if spring break will fall this year during an unanticipated cold spell.

    For our recent trip to Bologna, Italy, my family and I seemed to have pulled one of the worst cards in the deck: Our weather apps suggested early on that the high would be near 100 degrees Fahrenheit on the weekend of our arrival.
