Forecasters now predict that the coming El Niño—a warming of the Pacific Ocean that deeply affects global weather patterns—is likely to be as severe as the one in 2023-2024, which triggered severe flooding and prolonged heatwaves around the world.

At a young age, I learned quickly how oil wealth and power could burn the land while people struggled. I saw heat rise off the streets, the Nile strained, and the air thickened with injustice. In my teenage years, through Aotearoa, being on the edge of the Pacific, I felt the ocean breathing heavy, swallowing the shores of islands that have done the least to cause this harm.

The overarching message of The Economics of Climate Change: The Stern Review was that failing to invest in mitigating climate change would exact an alarmingly high price, estimated between 5% and 20% of global GDP per year.

Fatih Birol, president of the International Energy Agency, warned that the war in Iran is the greatest threat to energy security in history, with analysts describing the situation as an Armageddon.

Covering Climate Now was formed in 2019 in response to the climate silence that then prevailed in much of the press, especially in the United States. Over the years that followed, hundreds of newsrooms joined our effort, and press coverage of the story began to reflect the scale of the crisis. Newsrooms beefed up their climate reporting teams; they confronted misinformation that sought to play down the problem; they thought creatively about how to find the climate connection on every beat.

As water-intensive data centres expand worldwide, their impact on sanitation, inequality and disease is emerging as a serious and under-examined threat. Bubble is probably the word most associated with AI right now, though we are slowly understanding that it is not just an economic time bomb; it also carries significant public health risks. Beyond the release of pollutants, the massive need for clean water by AI data centres can reduce sanitation and exacerbate gastrointestinal illness in nearby communities, placing additional strain on local health infrastructure.

Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.

His message is clear: our world is built on abundant energy, around 80% of which has come from fossil fuels over the past 50 years. Because supplies are limited, energy consumption will peak in decades - sooner if humans attempt to limit climate change. To keep global warming below 1.5 °C by 2100, the use of fossil fuels must fall by 5-8% each year - a pace that is too fast for low-carbon energy to keep up with.

Plastic is everywhere. Inside the human body, in the depths of the ocean and the far reaches of the Arctic. Now a new study warns that, unless the world changes course, plastic could more than double its damage to human health within the next two decades. The culprit is not plastic litter in the environment or microplastics, but the emissions released across plastic's entire life cycle from fossil fuel extraction and manufacturing to transport, recycling and disposal.
