The UK Health Security Agency reported around 1,504 heat-associated deaths in England during summer 2025, roughly half the predicted 3,039, despite the season being the warmest on record.

We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

In 2019, scientists found that balloons eaten by seabirds are more likely to kill them than other kinds of plastic yet they do not seem to have been earmarked in the same way as, for example, plastic straws.

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.

Temperature and rainfall influence where malaria-carrying mosquitoes such as Anopheles species can survive and how well malaria parasites, such as Plasmodium falciparum, develop in them. Past predictions have been inconsistent and have often focused on where malaria might spread, rather than on how severely it could intensify where it already exists.

Rising temperatures are projected to increase the prevalence of physical inactivity, translating into additional premature deaths and productivity losses, especially in tropical regions. Prioritising heat-adaptive urban design, subsidised climate-controlled exercise facilities, and targeted heat-risk communication is essential to mitigate these emerging health and economic burdens, in addition to ambitious emissions reductions.

Risks of outbreaks with pandemic potential rise with increasing land-use change, biodiversity loss and climate change. The Pandemic Agreement adopted by the World Health Assembly in 2025 marks a historic shift that establishes the One Health approach as a legally binding obligation for pandemic prevention.

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.

Newsom's administration has touted his climate leadership, which has led to California's historic build-out of battery storage and the landmark program designed to reduce greenhouse gas emissions, newly renamed cap-and-invest - in California. But some environmental advocates and experts are second-guessing his climate record, including his support of legislation streamlining approval of new oil and gas wells, and not advocating for legislation that aims to hold industries accountable for fossil fuel-driven climate disasters.

"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."

The remaining question, though, was where all this methane was coming from in the first place. Throughout the pandemic, there was speculation that the surge might be caused by super-emitter events in the oil and gas sector, or perhaps a lack of maintenance on leaky infrastructure during lockdowns. But the new research suggests that the source of these emissions was not what many expected. The microbial surge

When the category-5 storm Hurricane Melissa struck Jamaica in October, its path crossed communities that had varying levels of preparedness. Many with maintained coastal protections, upgraded drainage and reliable early-warning systems had power and water restored in days. Others were immobilized for weeks.

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.

The past 11 years are now the warmest 11 years in the 176-year history of temperature records. What is especially concerning about 2025 is that it occurred during La Niña, a natural Pacific cooling pattern that usually brings lower temperatures. This time, it did not help. Climate scientist James Hansen reports that global warming is now speeding up by 0.31°C per decade, and he predicts we will pass the +1.7°C mark by 2027.

The household burning of plastic for heating and cooking is widespread in developing countries, suggests a global study that raises concerns about its health and environmental impacts. The research, published in the journal Nature Communications, surveyed more than 1,000 respondents across 26 countries. One in three people reported being aware of households burning plastic, while 16% said they had burned plastic themselves.
