No collapswashing

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 world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.

Na drie weken van keiharde repressie tellen de Iraanse demonstranten hun doden. Het exacte aantal is moeilijk na te gaan, maar getuigenissen en beelden van overvolle mortuaria, massagraven en doelgerichte moorden suggereren een duizelingwekkende dodentol. MO* sprak met mensen in Iran en in de diaspora om de ware omvang van de staatsterreur van de ayatollahs in kaart te brengen.

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.

Il y a quelques années, le gouvernement colombien avait tourné le dos à l’utilisation massive de l’herbicide pour détruire les cultures illégales des trafiquants de drogue. Depuis, il a changé d’avis : les épandages reprennent en ce mois de janvier, selon la volonté du président étasunien.

De eerste koude nachten zijn gevallen. In sommige straten worden dekens uitgedeeld aan mensen die nergens terechtkunnen, terwijl achter de ramen van regeringsgebouwen het licht nog brandt. Binnen wordt onderhandeld over cijfers, budgetten en opvangcapaciteit, maar zelden gaat het over de mensen zelf, vindt de Syrische Belg en opiniemaker Alaa Jbour.

Delegates made minimal headway on timetable for replacing oil and gas or on firm commitments to reducing carbon emissions

Watchdog’s flagship report says rise in low-carbon electricity will make transition ‘inevitable’, despite Trump’s calls to carry on drilling

Decision by international court of justice hailed as a gamechanger for climate justice and accountability

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.

The uniquely vulnerable West Antarctic Ice Sheet holds enough water to raise global sea levels by 5 meters. But when that will happen — and how fast — is anything but settled.

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

Four Prime Ministers in twelve months. Social protests in the streets. Extreme parties rising in the polls. President Macron, once seen as Europe's great reformer, seems politically finished. But what if France's paralysis is not an exception - what if it shows Europe's future?

Predictably, soon, most young people will reject extremist views. This will be none too soon because it is the essential step leading to global political leadership that appreciates the threat posed by climate’s delayed response to human-made changes of Earth’s atmosphere. Then the annual fraud of goals for future “net zero” emissions announced at United Nations COP (Conference of Parties) meetings might be replaced by realistic climate policies. It is important, by that time, that we have better knowledge of the degree and rate at which human-made forcing of the climate system must be decreased to avoid irreversible, unacceptable consequences.

The world will warm more than expected due to future changes in ozone, which protects the Earth from harmful sun rays but also traps heat as it is a greenhouse gas. While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone could warm the planet 40% more than originally thought.

In an analysis of the best available Earth systems models, Northeastern researchers found that by the turn of the next century, 850 million people will feel the effects of declining runoff from the world's major rivers.

The Environmental Protection Agency said on Friday that it would eliminate its scientific research arm and begin firing hundreds of chemists, biologists, toxicologists and other scientists, after denying for months that it intended to do so. The move underscores how the Trump administration is forging ahead with efforts to slash the federal work force and dismantle federal agencies after the Supreme Court allowed these plans to proceed while legal challenges unfold. Government scientists have been particular targets of the administration’s large-scale layoffs.

Au moment où le continent fait face à des températures extrêmes, la Commission européenne a entrepris d’affaiblir plusieurs politiques écologiques majeures, sous la pression conjointe des Etats membres, de la droite et de l’extrême droite.

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
