Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research. The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.

Paper in Nature Climate Change journal reveals major role wealthy emitters play in driving climate extremes. The world’s wealthiest 10% are responsible for two-thirds of global heating since 1990, driving droughts and heatwaves in the poorest parts of the world, according to a study.

The faces are different, but it’s the same authoritarianism. Keir Starmer’s team might not look or sound like Donald Trump’s, but its policies on protest and dissent are chillingly similar. So is the reason: coordinated global lobbying by the rich and powerful, fronted by rightwing junktanks.

Temperatures south Asians dread each year arrive early as experts talk of ever shorter transition to summer-like heat

Action urgently needed to save the conditions under which markets – and civilisation itself – can operate, says senior Allianz figure

A superpower in the fight against global heating is hiding in plain sight. It turns out that the overwhelming majority of people in the world – between 80% and 89%, according to a growing number of peer-reviewed scientific studies – want their governments to take stronger climate action.

Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

Greenpeace lost – not because it did something wrong but because it was denied a fair trial The stunning $667m verdict against Greenpeace last week is a direct attack on the climate movement, Indigenous peoples and the first amendment. The North Dakota case is so deeply flawed – at its core, the trial was really about crushing dissent – that I believe there is a good chance it will be reversed on appeal and ultimately backfire against the Energy Transfer pipeline company.

Researchers say Aardvark Weather uses thousands of times less computing power and is much faster than current systemsA single researcher with a desktop computer will be able to deliver accurate weather forecasts using a new AI weather prediction approach that is tens of times faster and uses thousands of times less computing power than conventional systems.
