Climate models that give a low warming from increases in greenhouse gases do not match satellite measurements. Future warming will likely be worse than thought unless society acts, according to a new study published in Science.

The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy Lenton

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Between 80% and 89% of the world’s people want their governments to do more about climate change. This fact is the central tenet of the 89% Project for climate journalism. Timed to coincide with Earth Day and Earth Week, the project launched in April, 2025, and will culminate in another week of focused stories in October, just before the next COP meeting in Brazil.

New data from Nasa has revealed a dramatic rise in the intensity of weather events such as droughts and floods over the past five years.The steepness of the rise was not foreseen. The researchers say they are amazed and alarmed by the latest figures from the watchful eye of Nasa’s Grace satellite, which tracks environmental changes in the planet.

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Ende August organisieren Klimaaktivisten das erste »Kollapscamp«, um solidarisch durch Krisen zu gehen

Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?

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

Ocean acidification has already crossed a crucial threshold for planetary health, scientists say in unexpected finding

A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

These are difficult times indeed, with terrible news on many fronts. What are the prospects for the degrowth1 alternative as we move through 2025? Dark times: the current context First, we need to understand what is going on around us: what is the evolving context with which degrowth has to contend, and to which it has to present a viable alternative?

Lenton, the founding director of the Global Systems Institute at the University of Exeter, was the lead author of the 2008 paper that formally introduced the idea of tipping points in the Earth’s climate system.

Surpassing 1.5°C of warming can be undone at a later date – using tech, land and resources that don’t exist.

Knowing that the world is ending can be incredibly lonely. Here's what it's like to be collapse aware among those who are oblivious.

Now that humans have overshot the carrying capacity of the planet, collapse is inevitable no matter what we do.

When it comes to our understanding of the unfolding global crisis, each of us seems to fit somewhere along a continuum of awareness that can be roughly divided into five stages:
