More than 1,500 giant tortoises have been reintroduced across parts of the Galápagos Islands in a major conservation effort aimed at rebuilding ecosystems disrupted by centuries of human activity and invasive species. The tortoises, once heavily reduced in number, are now being used as “ecosystem engineers,” helping to reshape vegetation patterns as they move slowly […]

Zettajoules (ZJ) are an extremely large unit of energy—equal to 10²¹ joules—used by climate scientists to quantify changes in the Earth system’s heat content. Recent measurements indicate that Earth’s energy imbalance is on the order of ~0.5 to 1 watt per square metre, which may sound small but, when integrated across the entire planet and

New climate-risk analysis finds that limiting global warming to 2°C may still trigger widespread and severe food insecurity across many more countries than previously expected. Researchers examining global crop yields and climate stressors warn that rising temperatures will intensify droughts, heatwaves, and rainfall variability, all of which directly reduce agricultural productivity. Key staple crops such

Large quantities of discarded electronics from wealthier countries continue to enter Nigeria, where they are often sold through informal markets under the guise of reusable second-hand goods. In reality, a substantial share of these imports is already broken or near the end of its usable life. Estimates from environmental monitoring groups suggest that tens of

A conservation project in a private reserve in South Africa is demonstrating how carbon markets can directly support ecosystem restoration and wildlife recovery. By monetising carbon sequestration through reforestation and grassland restoration, the reserve has been able to generate funding that is reinvested into removing invasive species, restoring native vegetation, and expanding protected habitats. The

A long-term field experiment in the Rocky Mountains shows how a relatively small rise in temperature—about 2°C—can significantly alter an entire ecosystem. Researchers heated sections of a natural alpine meadow using infrared equipment to mimic future climate warming and tracked changes over several decades. Instead of increasing overall plant growth, the warmer plots saw a

New research published in Nature estimates that emissions from the United States have contributed to more than $10 trillion in climate-related economic losses worldwide since 1990. By linking rising global temperatures to national emissions, scientists found that decades of fossil fuel use have driven extreme heat, droughts, and reduced productivity across many regions—slowing economic growth

Deforestation linked to palm oil is still pushing into key habitats of the endangered Bornean orangutan, even as scientists and conservationists raise serious concerns. On Borneo, forest areas that serve as crucial feeding and migration zones are being cleared for new plantations, including regions previously flagged for their high ecological value. In Indonesia’s Kalimantan region,

New research reveals that Earth’s 40,000-year axial tilt cycle—known as obliquity cycle—plays a crucial role in linking Antarctic ice sheet expansion with changes in ocean productivity far beyond the polar region. Scientists studying sediment cores and climate records found that when Earth’s tilt angle shifts, it alters how solar energy is distributed across the planet.

In the highly radioactive environment of the Chernobyl Exclusion Zone, scientists have discovered fungi that appear to not only survive but potentially thrive on radiation. Following the Chernobyl disaster, several species of “radiotrophic” fungi—particularly those rich in the pigment melanin—were found growing on reactor walls and contaminated soil. Studies suggest that these fungi may use
