Climate records preserved in cave formations show rainfall plummeted just as the small human species disappeared. At the same time, pygmy elephants they depended on declined sharply as rivers dried up. With food and water vanishing, the hobbits may have been pushed out—and into their final chapter.

By analyzing ancient caulking and cords from the Hjortspring boat, researchers uncovered traces of pine pitch and animal fat — materials that likely came from pine-rich regions east of Denmark along the Baltic Sea. This suggests the vessel, used by a band of Iron Age warriors who attacked the island of Als over 2,000 years ago, may have sailed across open waters on a long, carefully planned mission.

New research suggests that scavenging animal carcasses wasn’t a desperate last resort, but a smart, reliable survival strategy that shaped human evolution. Carrion provided calorie-rich food with far less effort than hunting, especially during hard times, and humans were uniquely suited to take advantage of it—from strong stomach acid and long-distance walking to fire, tools, and teamwork.

Researchers found that most people, especially in wealthy countries, are exceeding a “food emissions budget” needed to keep global warming below 2°C. Beef alone accounts for nearly half of food-related emissions in Canada. Small changes—less waste, smaller portions, and fewer steaks—could add up to a big climate win.

New evidence from plant waxes preserved in island sediments shows this change coincided with the final major wave of Polynesian expansion eastward. As freshwater became scarcer in the west and more abundant in the east, people may have been pushed to migrate, effectively “chasing the rain” across vast stretches of ocean.

New climate reconstructions show that the Indus Valley Civilization endured repeated long dry periods that gradually pushed its people toward the Indus River as rainfall diminished. These environmental stresses coincided with shrinking cities, shifting settlements, and eventually widespread deurbanization. Rather than a dramatic collapse, the civilization appears to have faded slowly under relentless climate pressure.

These forces made crowded, costly city life worthwhile for rural farmers. But when conditions improved in the countryside, people abandoned cities for more autonomy and better living environments. The story turns out to be far more complex than drought alone.

A new study quantifies the climate outcomes of these inequalities. It finds that the world's wealthiest 10% are responsible for two thirds of observed global warming since 1990 and the resulting increases in climate extremes such as heatwaves and droughts.

If global temperatures rise by 3.5 C by 2100, 92% of children born in 2020 will experience unprecedented heatwave exposure over their lifetime, affecting 111 million children. Meeting the Paris Agreement's 1.5 C target could protect 49 million children from this risk. This is only for one birth year; when instead taking into account all children who are between 5 and 18 years old today, this adds up to 1.5 billion children affected under a 3.5 C scenario, and with 654 million children that can be protected by remaining under the 1.5 C threshold.

While oxygenation approaches have already been proven successful in lakes, their potential side effects must be carefully analysed before they can be used in the sea. This is the conclusion of researchers from GEOMAR Helmholtz Centre for Ocean Research Kiel and Radboud University in the Netherlands. In an article in the scientific journal EOS, they warn: Technical measures can mitigate damage temporarily and locally, but they are associated with considerable uncertainties and risks. Above all, they do not offer a permanent solution because the oxygen content will return to its previous level once the measures end, unless the underlying causes of the problem, nutrient inputs and global warming, are not tackled.

This is due partly to specific weather conditions -- known as fire weather -- that facilitate the spread of wildfires. Researchers have found that fire weather seasons are increasingly overlapping between eastern Australia and western North America. The research team examined the causes of this shift and its implications for cross-border cooperation between fire services in Canada, the US, and Australia.
