Paul R. Ehrlich will be remembered as a scientist whose books about population and threats to the environment shaped the idea of limited growth in the modern era.

novembre 2025

The growth rate of greenhouse gas (GHG) climate forcing increased rapidly in the last 15 years to about 0.5 W/m2 per decade, as shown by the “colorful chart” for GHG climate forcing that we have been publishing for 25 years (Fig. 1).[1] The chart is not in IPCC reports, perhaps because it reveals inconvenient facts. Although growth of GHG climate forcing declined rapidly after the 1987 Montreal Protocol, other opportunities to decrease climate forcing were missed. If policymakers do not appreciate the significance of present data on changing climate forcings, we scientists must share the blame.

German scientists warn global warming is accelerating faster than expected, raising the risk of a 3 °C rise by 2050 and forcing Europe to confront unthinkable adaptation plans.

EU officials warn climate breakdown and wildlife loss ‘are ruining ecosystems that underpin the economy’ […] The European way of life is being jeopardised by environmental degradation, a report has found, with EU officials warning against weakening green rules. The continent has made “important progress” in cutting planet-heating pollution, according to the European Environment Agency, but the death of wildlife and breakdown of the climate are ruining ecosystems that underpin the economy.

Forever chemicals have polluted the water supply of 60,000 people, threatening human health, wildlife and the wider ecosystem. But activists say this is just the tip of the Pfas iceberg

Fifteen years ago, smack in the middle of Barack Obama's first term, amid the rapid rise of social media and a slow recovery from the Great Recession, a professor at the University of Connecticut issued a stark warning: the United States was heading into a decade of growing political instability.
There’s frustration among researchers that falling pH levels in seas around the globe are not being taken seriously enough, and that until the buildup of CO2 is addressed, the consequences for marine life will be devastating

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

When Rishi Sunak granted 27 new North Sea licences this week, he wasn’t thinking about the survival of the living world, says Guardian columnist George Monbiot
the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”

Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more

The UN Secretary-General’s Early Warnings for All Initiative (EW4All) is rapidly gaining ground. Action plans are being rolled out around the world to ensure that people know when dangerous weather is headed their way. Tajikistan has held a two-day national consultation, co-chaired by the Deputy Prime Minister and the UN Resident Coordinator in Tajikistan, and bringing together key stakeholders from state and international organizations, media and civil society. Ethiopia also held an inception workshop.
Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted

Humanity received a “final warning” Monday from the UN Intergovernmental Panel on Climate Change. The bottom line of the Synthesis Report of the IPCC’s Sixth Assessment Report is to “act now, or it’s too late,” the Guardian wrote. The scale of the emergency screams out from almost every page — climate change is already displacing and killing millions of people globally — but the report also provides what UN Secretary-General António Guterres called a roadmap for defusing the “climate time bomb.”
IPCC report says only swift and drastic action can avert irrevocable damage to world

There's no time for complacency, according to Dr. Peter Carter, founder of the Climate Emergency Institute
February 28, 2022. Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.
Russia’s military offensive against Ukraine is an act of aggression that will make already worrisome tensions between Nato and Moscow even more dangerous. The west’s new cold war with Russia has turned hot. Vladimir Putin bears primary responsibility for this latest development, but Nato’s arrogant, tone‐​deaf policy toward Russia over the past quarter‐​century deserves a large share as well. Analysts committed to a US foreign policy of realism and restraint have warned for more than a quarter‐​century that continuing to expand the most powerful military alliance in history toward another major power would not end well. The war in Ukraine provides definitive confirmation that it did not.

With global warming intensifying the water cycle, floods and droughts are increasing, and many countries are unprepared.

Climate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points. The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic Meridional Overturning Circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown.
