Earth’s climate system is moving deeper into uncharted territory. We present the 2026 update of planetary vital signs that track the state of Earth’s climate system, alongside indicators of the human activities driving ongoing change. Of 16 climate-related indicators, seven are currently at record extremes. Several indicators also show evidence of accelerating trends or abrupt shifts, raising concerns about increasing climate instability, interacting feedbacks, and the growing risk of crossing critical tipping points. Human activities, particularly fossil fuel combustion, remain the dominant drivers of these changes. Despite the worsening trends, encouraging signs of societal changes are emerging, including the rapid expansion of renewable electricity and battery storage, although progress remains far below the scale and speed needed to stabilize Earth’s climate system. Rapid reductions in greenhouse gas emissions, effective adaptation, ecosystem protection, and transformative societal change remain essential

Four months into US oil blockade, Cubans see island drained as state electric company fights to provide even a few hours of power a day Ruaridh Nicoll in Havana - The doctor called from the darkness, a shadowy figure sitting on the stoop of his apartment building. “I want to tell you we’ve been four days without light,” he said. “And without electricity, water is also a problem. And there are mosquitoes everywhere.”

The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

The ecological concept of human carrying capacity is necessarily complicated because human beings are the ‘ultimate ecosystem engineers’ who moderate the environment for their benefit. For at least the last few hundred years, human ingenuity, access to massive stocks of fossil fuels, and technological development have driven facilitation whereby increasing human abundance has promoted higher population growth rates. However, this positive relationship broke down during the 1950s, and by 1962, the global human population entered a phase where the growth rate consistently declined as population increased. The onset of this negative phase occurred 8 years before a global biocapacity deficit began in 1970. The onset of the negative phase also varies regionally, with the lowest-income and highest fertility regions entering this phase later than higher-income regions. A Ricker logistic model fitted to the negative phase predicts that the global population could reach 11.7–12.4 billion people between 2067 and 2076.
