Herders and experts tell the BBC how Africa's camels are suffering because of extreme heat.

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

Modi denied climate change for years. Now, as heat deaths mount, his government offers branding instead of protection.

A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.

Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people

In a Swiss forest lab, scientists tracked how beech and oak leaves cool themselves and pinpointed the moment heat and drought push them past their limits.

Using a field experiment, we measured the heat tolerance of insects across many different groups. This is important because most previous studies either combine inconsistent datasets or focus on a single species. Our goal was to understand how entire insect communities respond to heat. We looked at a large variety of insects, such as flies, bees, beetles, butterflies and grasshoppers, to name just a few. We found that many are likely to face dangerous levels of heat stress. This was true even under conservative assumptions, including the possibility that species move into cooler habitats.

​"Extreme heatwaves like the one impacting the Western US this month are one of the catastrophic disasters these companies predicted their conduct would bring about," said Public Citizen.

Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño

Welcome to the Global Climate Highlights 2025 report, compiled by the Copernicus Climate Change Service (C3S). The Global Climate Highlights 2025 report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others.

By the end of this century, parts of Africa could face heatwaves for 250-300 days a year, which will make it difficult for people to survive.

Le nord du Mozambique abrite d'énormes réserves de gaz qui font l'objet d'importants projets d'exploitation portés par des multinationales comme le français TotalEnergies, l'Italien ENI ou l'Américain ExxonMobil. Ces projets sont situés dans la province du Cabo Delgado, dans le nord du pays, où sévit une insurrection jihadiste meurtrière depuis 2017.

Scientists expect 41% of the projected global population to face the extremes, with ‘no part of the world’ immune

The world's oceans absorbed a record amount of heat in 2025, an international team of scientists said Friday, further priming conditions for sea level rise, violent storms, and coral death.
