Climatologists say a particularly powerful weather pattern could amplify wildfire risk, heatwaves and flooding worldwide as global temperatures continue to rise
Rights-based, post-growth policies that make poverty eradication a deliberate outcome of restructured economies — not a trickle-down side effect of destructive growth.
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”.
Wildfires used to die down and even stop at night with cooler temperatures and increased humidity. But a study released Friday says climate change is making burning weather more around the clock in North America because night is becoming warmer and drier. Canadian fire scientists say potential burning hours for fires have increased 36% in the last 50 years. California now has about 550 more fire-friendly hours a year than it did in the 1970s. North American summer nights are warming faster than days, evening relief is evaporating for forests and that means the area of land burned is soaring.
A team including scientists, Indigenous people and conservationists point to the ecosystem connecting Yellowstone and the Yukon as an example of a region where humans and nature are flourishing together.
In a Swiss forest lab, scientists tracked how beech and oak leaves cool themselves and pinpointed the moment heat and drought push them past their limits.
Around 153 BCE, Cato the Elder, one of Rome’s most prominent senators, began ending every single one of his speeches with the same words: “Carthago delenda est”, or “Carthage must be destroyed”.
Researchers in Japan have developed a new material that allows solar cells to generate an amount of energy from sunlight that was previously thought impossible. The discovery, made by a team at Kyushu University, involves a special “spin-flip” emitter that can harvest energy from the Sun that is typically lost as heat. The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of 130 per cent – opening up new possibilities for ultra-efficient solar panels.
Critics say brash, bombastic Fox News host out of his depth to guide US military through murky new Middle East conflict
El Niño could fuel extreme weather and raise temperatures to record highs this year, but how sure can we be that it will return?
The new joint policy brief offers a deep dive into the ways in which the social and solidarity economy can advance the objectives of the Roadmap by supporting the eradication of poverty beyond growth.
As global soy giants walk away from a landmark pact, land grabbers move in to clear the forest for new crops.
New year, new acronym! The newly established Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution (ISP-CWP) will meet in its first Plenary session from February 2-6 in Geneva, Switzerland. The Panel is designed to provide scientific assessments on chemicals, waste, and pollution to inform policymakers at national, regional, and international levels.
Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery
Satellite analysis warns that widespread land subsidence threatens 1.6 billion people by 2040, with 86% of the at-risk population concentrated in Asia
“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.
The Environmental Protection Agency is moving forward with approvals for pesticides containing “forever chemicals” as an active ingredient, dismissing concerns about health and environmental impacts raised by some scientists and activists. This month, the agency approved two new pesticides that meet the internationally recognized definition for per- and polyfluoroalkyl substances, also known as PFAS or fluorinated substances, and has announced plans for four additional approvals.
A “pushing and triggering” mechanism has has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across the atmosphere, ocean and cryosphere this century.
This year, ExxonKnews reported on Big Oil targeting its critics, pushing false solutions, and encouraging political allies to help the industry escape accountability.
The datasets used to diagnose the modern history of the planet’s climate — and to proclaim that the world is now very near to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming — typically begin with the year 1850. The new one goes all the way back to 1781. This extended time frame matters because greenhouse gases in the atmosphere increased 2.5 percent between 1750 and 1850, enough to have caused some warming that the data hasn’t accounted for.
