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

Een rechtvaardig grondstoffenbeleid is een voorwaarde voor duurzame vrede in Congo, weet Wies Willems die als expert natuurlijke rijkdommen werkt voor Broederlijk Delen. Ook de EU moet daarin haar verantwoordelijkheid opnemen, benadrukt hij.

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global

I am writing this message to the millions of people who have been involved in the climate movement over the past several years. This movement has been an incredible force, thanks to your courage, passion and commitment. It has created a new public consciousness and a powerful sense of popular will. These are major achievements. And yet it is clear that we have now reached an impasse and a new path is needed.

On 21 April 2019, I was on Waterloo Bridge in London with my younger siblings. Around us were planters full of flowers where there were once cars, and people singing. This was the spring iteration of Extinction Rebellion, when four bridges in London were held by protesters. My siblings, then 14, had been going out on school strike inspired by Greta Thunberg, and wanted to see her speak.

Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times. Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times.

Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

Outdoor field trials which could include injecting aerosols into the atmosphere, or brightening clouds to reflect sunshine, are being considered by scientists as a way to prevent runaway climate change. Aria, the Government’s advanced research and invention funding agency, has set aside £50 million for projects, which will be announced in the coming weeks.

Sous l’impulsion du duo Donald Trump-Elon Musk, l’exécutif américain a annoncé de nombreux licenciements dans l’administration. Difficiles à suivre et à compter, ces coupes dans les effectifs révèlent les cibles prioritaires de la Maison Blanche.

Engagé de longue date dans le soutien aux parents d’enfants neuroatypiques, le président des Etats-Unis défend des positions archaïques sur l’autisme. Depuis vingt ans, sa vision est influencée par la fille d’un couple d’amis, passée de l’errance médicale à un combat antivax. C’est l’histoire d’une lubie trumpiste pas comme les autres. En mars, le nouveau ministre de la santé des Etats-Unis, le lobbyiste Robert F. Kennedy Jr, a confié aux Centres de contrôle des maladies (CDC), la principale agence de santé du pays, la mission d’étudier le lien fantasmatique entre autisme et vaccination.

Morgan Stanley, JPMorgan and an international banking group have quietly concluded that climate change will likely exceed the Paris Agreement’s 2 degree goal.Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.
