43 h. ago I’m obsessed with brittle stars: fish often nip off bits of their arms but they regenerate

These starfish relatives have lots of remarkable features and are a keystone species. My hope is that we will recognise how vital these charismatic creatures areBrittle stars have a lot of remarkable features as a species. Many of them are bioluminescent and can flash blue light; some will have patterns and do displays. These slender relatives of starfish can be very beautiful to look at and come in a range of colours – in the tropics, for example, they can be red, black or orange. And they’ve got spines all over them, so they can look quite ornate.They can also regenerate. Fish and other creatures will often nip off bits of their arms – known as sublethal predation – so they are constantly regenerating themselves. You can even break off all their arms, and sometimes even half the disc, and the brittle star will still regenerate. Continue reading...

Rapporteur calls for defossilization of economies and urgent reparations to avert ‘catastrophic’ rights and climate harmsA leading UN expert is calling for criminal penalties against those peddling disinformation about the climate crisis and a total ban on fossil fuel industry lobbying and advertising, as part of a radical shake-up to safeguard human rights and curtail planetary catastrophe.Elisa Morgera, the UN special rapporteur on human rights and climate change who presents her damning new report to the general assembly in Geneva on Monday, argues that the US, UK, Canada, Australia and other wealthy fossil fuel nations are legally obliged under international law to fully phase out oil, gas and coal by 2030 – and compensate communities for harms caused.

3 d. ago ‘Positive cascades could help accelerate change’: social tipping points expert on fixing climate crisis

The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy LentonTimothy Lenton is a professor of climate change and Earth system science at the University of Exeter. He started working on tipping points in the 1990s, making him one of the first scientists in the world to study this form of planetary risk. In an upcoming book, Positive Tipping Points: How to Fix the Climate Crisis, he argues the Earth has entered an “unstable period” but humanity can still prevail if we can trigger positive social and economic tipping points to reverse the damage that has already been done. On 30 June, he will host a global conference on tipping points. Continue reading...

6 d. ago Antarctic ice has grown again – but this does not buck overall melt trend

Study shows ice sheet gained mass from 2021 to 2023, due to extreme snowfall that was also an effect of climate crisisA new study shows that after decades of rapid decline, the Antarctic ice sheet actually gained mass from 2021 to 2023. This is a reminder that climate change does not follow a smooth path but a jagged one, with many small ups and downs within a larger trend.The research, published in the journal Science China Earth Sciences, showed that while the ice sheet lost an average of 142bn tonnes each year in the 2010s, in the 2021 to 2023 period it gained about 108bn tonnes of ice each year.

7 d. ago ‘This is a fight for life’: climate expert on tipping points, doomerism and using wealth as a shield

Economic assumptions about risks of the climate crisis are no longer relevant, says the communications expert Genevieve GuentherClimate breakdown can be observed across many continuous, incremental changes such as soaring carbon dioxide levels, rising seas and heating oceans. The numbers creep up year after year, fuelled by human-caused greenhouse gas emissions.But scientists have also identified at least 16 “tipping points” – thresholds where a tiny shift could cause fundamental parts of the Earth system to change dramatically, irreversibly and with potentially devastating effects. These shifts can interact with each other and create feedback loops that heat the planet further or disrupt weather patterns, with unknown but potentially catastrophic consequences for life on Earth. It is possible some tipping points may already have been passed. Continue reading...

9 d. ago The Guardian view on extreme weather: build national readiness – or let everyday life keep breaking down | Editorial

Britain faces rising climate threats, yet lacks a country adaptation plan. Urgent, coordinated investment is needed to protect lives and infrastructureBritain’s four-day heatwave – made 100 times more likely by the climate crisis – is expected to claim about 600 lives. Researchers say high temperatures from Thursday to Sunday would lead to a sharp rise in excess mortality, especially among older people in cities such as London and Birmingham. They forecast the deadliest day as Saturday, with temperatures above 32C and about 266 deaths. These are not abstract figures, but lives cut short by a threat we understand, yet remain unprepared for.Young people seem to grasp this. In a YouGov poll last week, roughly a quarter of 18- to 24-year-olds said they hoped there wouldn’t be a heatwave – while more than two-fifths of older people welcomed the sunshine. That generational split isn’t just cultural. It reflects an entirely rational anxiety: younger people face a future living in a climate...

It was the UK’s warmest spring on record and its driest in more than 50 years.Communicating the urgency of our predicament without provoking despair and hopelessness is an intractable challenge, especially when it comes to children. But two trail-blazing theatre experiences are bringing the breakdown of the natural world into urban metropolises, and raising the alarm with such immediacy that even those of us fortunate enough to live in places that have so far been relatively unaffected by the climate crisis must pay attention.
