Olivier De Schutter says new economic agenda needed to tackle crises of rising inequality and ecological collapse
Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) levels from the U.S. National Health and Nutrition Examination Survey (NHANES) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both Ca and Phave decreased steadily over the same period. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. Studies indicate that, after this time, elevated atmospheric carbon dioxide
A critical step on the path towards climate neutrality, the European Union’s 2040 target calls for a 90-per-cent reduction in emissions. Yet as far-reaching as this goal may seem, its provisions constitute a weakening of Europe’s climate ambitions under the Green Deal. By allowing costly and ineffective CO2 removal and storage technologies as a way of lowering emissions, the target risks deterring direct emission cuts and outsourcing pollution.
By the end of this century, parts of Africa could face heatwaves for 250-300 days a year, which will make it difficult for people to survive.
Today, we are close to the critical moment when conventional economic growth becomes impossible on a finite planet, constrained by two parallel factors: resource depletion and pollution. Tthe depletion of fossil fuels and other mineral commodities is placing heavy constraints on both industrial and agricultural production. We are not running out of anything yet, but the cost of extraction is increasing, just as the damage that extraction causes to the ecosystem. On the other side, pollution is appearing in more than one form. Chemical pollution is growing in terms of heavy metals, endocrine-disruptors, and other poisoning substances, while climate change can be seen as another form of pollution generated by the excess of CO2 in the atmosphere.
The Senate is on the verge of taking up a bill with the Orwellian title “Fix Our Forests Act.” It is designed to do the opposite, as Dan Galpern and I describe in an op-ed published yesterday in the Boston Globe, which is copied below with permission of the Globe. The bill would result in swaths of the public’s national forests becoming “categorical exclusion” zones open to logging exempt from any environmental review. Thus, the bill would override the purposes for which national forests were set up, including “outdoor recreation, range…watershed, and wildlife and fish purposes.” This sin is rationalized under the pretense that the Act will reduce wildfire risk and improve forest health by “thinning” the forest. This is nonsense, as our op-ed discusses.
Breathing in air pollution like ozone and PM2.5 harms nearly every major system in the human body
Melting glaciers, coastal areas wiped off the map and regular 40C heat in Europe. Climate experts warn the gloomy predictions of long term environmental change are no longer the future - they are already here. Last year was the third hottest on record, with the World Meteorological Organization this week warning that 2025 continued a run of “extraordinary” global temperatures. The EU has said the Paris climate agreement of 1.5C could be broken before 2030, a decade sooner than expected.
Bronwen Maddox says Trump’s rejection of international law leaves UK and Europe facing huge dilemma
Legal action has brought important decisions, from the scrapping of fossil fuel plants to revised climate plans
Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic. In a new study soon to be published in Geophysical Research Letters, I present evidence for hundreds of these quakes in Antarctica between 2010 and 2023, mostly at the ocean end of the Thwaites Glacier – the so-called Doomsday Glacier that could send sea levels rising rapidly if it were to collapse.
Watchdog’s flagship report says rise in low-carbon electricity will make transition ‘inevitable’, despite Trump’s calls to carry on drilling
We already have plenty of evidence of what happens when things better left to governments — which in this case might decide to never flip the switch at all — are ceded to private industry.
Facebook and other social media platforms need to act to stop intimidation and harassment of environmental protectors
President Donald Trump has been sending campaign fundraising emails with the subject line: “I want to try and get to Heaven.” The emails follow recent public remarks regarding Russia’s war on Ukraine, in which he said he was trying to “get to heaven,” comments which gained national attention. Framing his political survival and legal battles as signs of divine purpose, the emails request supporters to donate $15 during a “24-HOUR TRUMP FUNDRAISING BLITZ.”
Farming seaweed, changing ocean chemistry, breeding corals and restoring mangroves could help fight climate change – if assessed and managed responsibly.
The 511 billion barrels reported is nearly double Saudi Arabia’s proven reserves and more than ten times the North Sea’s output over the last 50 years.
Suspension of Soy moratorium could open up area of rainforest the size of Portugal to destruction
Forests have historically acted as a reliable planetary thermostat. They regulate Earth’s temperature by removing carbon dioxide (CO2) from the atmosphere and locking it in trees, roots and soil — carbon that is emitted if trees are cut down. In a typical year, forests and other vegetation absorb roughly 30% of the carbon that humans emit from burning fossil fuels — a vital climate service performed at virtually no cost by trees around the world, from tropical rainforests to temperate and boreal forests.
The Trump administration is releasing its proposal to undo the “endangerment finding,” the long-standing rationale and legal imperative for regulating greenhouse gases under the Clean Air Act
