Current conditions: San Francisco received a record-breaking amount of rain yesterday • Madagascar has been struck by two tropical cyclones in the span of a week • Scientists are warning of an “extreme winter warming event” unfolding at the north pole.
THE TOP FIVE
1. Top climate scientist warns of accelerating global warming
Climate scientist James Hansen has published a new study concluding the world is on track for more than 2 degrees Celsius in warming by 2045. Hansen has been saying for some time that current climate models underestimate the rate at which global temperatures are rising. The new research, published in the journal Environment: Science and Policy for Sustainable Development, says that we have been artificially cooling the planet with aerosol pollution for years. With new shipping regulations limiting these aerosols, this cooling effect is waning and warming will ramp up rapidly – probably by about 0.2 or 0.3 degrees Celsius per decade. “Unless actions are taken to reduce global warming,” the study warns, “shutdown of the Atlantic Meridional Overturning Circulation (AMOC) is likely within the next 20-30 years.”
Hansen has a long history of presenting alarming climate studies that divide the scientific community. But much of his work has proven to be remarkably prescient. In 1988 he famously warned Congress that human activity was changing the climate. In 2023, Hansen published controversial work projecting that the world would breach 1.5 degrees Celsius in warming much sooner than expected. “In the next several months,” he said, “we’re going to go well above 1.5C on a 12-month average.” Last year was indeed the first full calendar year during which the 1.5 Celsius threshold was broken. In fact the average temperature for the whole of last year was 1.6 degrees Celsius higher than pre-industrial times. This year is already confounding scientists who were expecting things to cool down a little bit: Last month was the hottest January on record, with temperatures 1.75 degrees Celsius warmer than pre-industrial years.

2. Climate pages removed from government websites
Government websites are being scrubbed of references to climate change. So far climate pages have stopped working on websites for the Departments of Defense, State, Agriculture, and Transportation. A “climate change” landing page for the White House does not load. Climate scientist David Ho noted that a page charting CO2 atmospheric trends has also been removed from the National Oceanic and Atmospheric Administration website.
Meanwhile, President Trump this week nominated Neil Jacobs to lead NOAA. Jacobs was acting NOAA head in 2019 when Trump infamously used a Sharpie to draw the path of Hurricane Dorian to suggest the storm would hit Alabama, contradicting weather forecasts. NOAA backed the president’s statements, prompting an investigation that concluded Jacobs violated scientific integrity policy.
3. Leaked memo reveals Trump has paralyzed renewables permitting
Chaos within the Trump administration has all but paralyzed environmental permitting decisions on solar and wind projects in crucial government offices, including sign-offs needed for projects on private lands, reported Heatmap’s Jael Holzman. According to an internal memo issued by the American Clean Power Association, the renewables trade association that represents the largest U.S. solar and wind developers, Trump’s Day One executive order putting a 60-day freeze on final decisions for renewable energy projects on federal lands has also ground key pre-decisional work in government offices responsible for wetlands and species protection to a halt. Renewables developers and their representatives in Washington have pressed the government for answers, yet received inconsistent information on its approach to renewables permitting that varies between lower level regional offices. “In other words,” Holzman wrote, “despite years of the Republican Party inching slowly toward ‘all of the above’ energy and climate rhetoric that seemed to leave room for renewables, solar and wind developers have so far found themselves at times shut out of the second Trump administration.”
4. Many countries will miss February NDC deadline
The deadline for countries to submit new climate targets is fast approaching, and many of the world’s largest polluters are not ready. Under the Paris Agreement, nations have until February 10 to submit their nationally determined contributions (NDCs) outlining 2035 emissions goals and plans for reaching those goals. According to the Financial Times, the European Union, India, Australia, and South Africa will likely miss the deadline. One expert estimated that just one third of G20 economies would submit their plans on time. “Because of the shock of the U.S. presidency and all the other issues, there is not a lot of leader attention on this issue,” said Nick Mabey, co-founder of climate think-tank E3G. There’s no penalty for a late submission, and some say that filing a little late is fine so long as the final plans are robust. “This next round of NDCs may be the most important documents to be produced in a multilateral context so far this century,” UN Climate Change Executive Secretary Simon Stiell said last year. “As they add up, they will determine which direction the world will take over the coming decades.”
5. Judge dismisses Chamber of Commerce claims against California climate laws
A California judge on Monday sided with the state in its legal battle with the U.S. Chamber of Commerce and other business groups by dismissing two claims that California’s climate laws violate the Constitution. The laws in focus require that large companies report their emissions and any climate-related financial risks. The Chamber of Commerce filed its complaint against the laws last year, saying they were in violation of the First Amendment because they “unlawfully attempt to regulate speech.”
THE KICKER
A geoengineering project in the Arctic involving using glass beads to try to reflect some of the sunlight has been shut down over concerns that the beads pose a “potential risks to the Arctic food chain.”
