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 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.

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.

Because so many American cities are so heavily car-dependent, most U.S. residents have no choice but to pony up the cash and drive anyway. Indeed, even when gas prices climbed above $5 a gallon in 2022, driving did not plummet; a Time magazine analysis at the time found that 'the only time that fuel consumption really took a hit in the last 23 years was during the pandemic.'

"Singapore is in a very unique position because they face a lot of land constraints, so there are few ways for them to generate their own renewable energy. Singapore is pushing for integrated energy systems throughout ASEAN, so that renewable energy produced in other countries can be brought back to Singapore. There's a very distinct, coordinated effort for countries to come together to work on climate change and energy security in a way that I haven't really seen."

The logic behind electric vehicles benefiting public health has long been solid: More EVs means fewer internal combustion engines on the road, and a reduction in harmful tailpipe emissions. But now researchers have confirmed, to the greatest extent yet, that this is indeed what's actually happening on the ground. What's more, they found that even relatively small upticks in EV adoption can have a measurably positive impact on a community.

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.

Many human activities - from improper disposal of waste to the degradation of car tyres - release small plastic particles, which have infiltrated the atmosphere, oceans and other ecosystems. These include nanoplastics - particles measuring less than 1 micrometre across - and microplastics, which range from 1 micrometre to around 5 millimetres. They've entered our bodies and brains, and scientists are still working to understand their effects on people's health.

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

Researchers used satellite data to see how much nitrogen dioxide was in California's air between 2019 and 2023. As the number of electric cars and plug-in hybrids rose, neighbourhoods had lower NO concentrations. Everybody knows that electric cars don't emit carbon emissions because they don't burn any fuel. And while there are some studies out there that show how zero-emission cars can improve the quality of air in urban areas, they weren't always definitive.
