   Researchers report Earth's climate vital signs at record extremes in 2026

   Researchers writing in the peer-reviewed journal BioScience say Earth's climate has been pushed to, and perhaps beyond, its limits in 2026, with several vital signs at record extremes and others accelerating or shifting abruptly. July 2026 was the warmest month ever recorded for the contiguous United States, and ocean temperatures hit new highs. Heat waves scorched Europe and fueled US wildfires. The researchers warn of rapid destabilization, as warming raises the risk of self-reinforcing feedback loops, such as permafrost thaw. Coral reefs became the first system to reach a climate tipping point, in 2025. Renewable energy is growing, yet greenhouse gas emissions remain at record highs, and progress is far below what stabilization requires.

   Key facts

   • Seven of 16 planetary vital signs are at record extremes, according to BioScience research.
   • Atmospheric carbon dioxide is 50 percent above preindustrial levels, due to burning fossil fuels.
   • Warming has accelerated from 0.05°C per decade (1880–1970) to 0.36°C per decade (2010–2024).
   • Greenland and Antarctic ice sheets have shrunk to record lows.
   • Heat waves in Europe killed an estimated 14,000 people.

   Commentary

   The notable change is the researchers' move from warning about the future to diagnosing the present, compressing the time left to respond. Clean power is growing, but the researchers say it is not enough to reverse the deterioration, making pace the real question. If feedback loops take hold, each year of delay narrows the window for pulling back.

   Study finds early humans in New Mexico lived through abrupt ice age climate shifts

   Researchers analyzed ancient pollen and sediments from White Sands National Park in New Mexico, which holds what are thought to be the oldest human footprints in the Americas. A study published in Science Advances reconstructs the landscape those people crossed, where a massive lake receded and conifer forest gave way to sagebrush and oak steppe. The record resolves change at about the timescale of a human generation, revealing severe aridity during a warming event also recorded in Greenland ice cores. Co-author Jessica Tierney said local changes followed global climate shifts. Live Science reported that the footprints' age is subject to some scientific debate, while the University of Arizona said the study reaffirmed their age.

   Key facts

   • Vegetation shifted from pine forest to pinyon and juniper within about 100 years.
   • Lake Otero's water level rose and fell over roughly 1,500 years, based on Ruppia pollen.
   • Temperatures were around 50 degrees Fahrenheit then, compared with an annual mean near 60 today.
   • Footprints at White Sands date to 23.5 to 21.7 thousand years ago, during the Last Glacial Maximum.
   • Researchers isolated up to 75,000 pollen grains per sample to refine the footprints' dating.

   Commentary

   What moved is less the climate itself than its speed relative to the people living through it. If a warming event seen in Greenland can dry the Southwest within lifetimes, the mechanism the team now seeks matters, because the people on that shore faced a risk their footprints never show.

   Study finds heat waves and wildfire smoke increasingly hit people at the same time

   A study published in Science Advances, described as the largest global assessment to date, finds that more people are facing heat waves and fires at the same time, with the number jumping sharply from the previous decade. The researchers link the growth to climate change, and lead author Yao Wu of Monash University said it stems mainly from people experiencing the two hazards together more often, not simply from there being more people. Researchers from universities in China and Australia called the trend alarming, arguing that public health plans addressing one climate-related hazard at a time are not sufficient as disasters increasingly overlap. Both hazards can be deadly.

   Key facts

   • Exposed population rose from 761 million a year in 2000–2009 to over 1 billion in 2010–2019.
   • Average days of dual exposure per person a year rose from one in 2000–2009 to 1.7 in 2010–2019.
   • Zambians had nearly a month of dual exposure per person a year, among the study's highest.
   • Democratic Republic of Congo, Indonesia, Mexico, Brazil and Russia together accounted for over half of global exposure days in 2010–2019.
   • Fire-related air pollution in low-income countries is four times worse than in wealthy countries, the researchers said.

   Commentary

   What moved is how often the two hazards coincide, not how many people live near them, tying the risk to a warming climate rather than population growth. The heaviest per-person burden falls where capacity to adapt is weakest, so the cost lands hardest on poorer nations. Plans treating heat and smoke separately target the wrong problem.

   Prop. 45 would limit environmental reviews for some California projects

   Proposition 45, on California’s November ballot, would create a streamlined approval process under the California Environmental Quality Act for certain projects, with deadlines that push state agencies and courts to decide quickly. Gov. Gavin Newsom, speaking at the California Economic Summit in Long Beach, decried the “weaponization” of environmental law and the litigation that delays projects, yet he has not taken a position on the measure. Backers, including the California Chamber of Commerce, say delays raise costs for taxpayers and hold up housing and infrastructure. Opponents, including environmental, public health and labor groups, say it would strip protections and local control. Both campaigns have used Newsom’s remarks to make their case.

   Key facts

   • Prop. 45 covers eight categories of building projects, including housing, hospitals, clean energy, schools, broadband, transportation and wildfire mitigation.
   • The California Democratic Party opposes Prop. 45, but many of its leading officials have stayed silent.
   • Annual cost estimates around $100 million: Secretary of State via University Times, Legislative Analyst's Office via PIRG.
   • Prop. 45 would set a 365-day limit on environmental reviews for certain projects.
   • In 2025, Newsom threatened to veto the state budget unless lawmakers passed two CEQA reform bills.

   Commentary

   The notable gap is not in Newsom’s message but in his ballot silence: he attacks litigation-driven delays while declining to back the measure that would most directly shorten them. That lets him claim reform credit without owning the trade-off, since the fight over who bears the cost of faster approvals is left to the campaigns.

   Oregon governor pauses air and water pollution permits for data centers until next July

   Governor Kotek has ordered state environmental regulators to pause approving new state and federal air and water pollution permits for data centers, which the Oregon Capital Chronicle called effectively a moratorium. She says the pause lets her weigh advisory committee recommendations and leaves room for reforms in the 2027 legislative session, and that she lacks power to impose a statewide moratorium without legislative action. Amazon Web Services vice president Shannon Kellogg countered that the pause was issued abruptly and would eliminate thousands of construction jobs and halt billions of dollars in planned investment. Oregon Rural Action said the pause could affect a proposed Amazon facility in Boardman.

   Key facts

   • The permit pause is set to last until next July.
   • An earlier roughly one-year pause halts approvals for data centers on state land or in state buildings.
   • The committee's 20-page preliminary report departed from the cost-benefit analysis it was tasked with providing.
   • Public comments on the committee's findings are due by 5 p.m. Oct. 24.
   • Oregon Rural Action says 700 people signed a petition seeking an in-person hearing on Amazon's Boardman air permit.

   Commentary

   The timing matters more than the stated rationale: the order came unannounced days before a debate in which Kotek's opponent attacked her past support for data center tax breaks. After more than two months of declining to discuss the industry, a pause framed as a short evaluation suggests she is managing the issue as much as studying it.
