A landmark report by the United Nations concludes that ‘global collapse’ is becoming more likely. But was it watered-down before being published?

The study found that the concentration of nitrogen oxides released into the atmosphere was considered "hazardous to human health" under WHO standards.

Exclusive: Oil and gas majors are planning scores of vast projects that threaten to shatter the 1.5C climate goal. If governments do not act, these firms will continue to cash in as the world burns

Mounting evidence suggests humans are now a major driving force of evolution on Earth. From selective breeding to environmental modifications, we're altering so much of our world that we're not only now driving the climate, but the direction of life

We've known for a while that Earth's deepest depths, its "solid iron" inner core, isn't made of pure iron — and now scientists say it might not be solid either.

Second world war codebreaking calculations used at Bletchley Park find 9,000 of those species are yet to be discovered

You might think that clouds are clouds all over Earth, but that's not quite so.

New results from a long-running public opinion survey show that about 1 in 3 Americans is now "alarmed" by global warming. Is it any wonder, given the horrific onslaught of fires, floods, heat waves and other climate disasters we've experienced in the last year alone?

The Earth’s core consists of two parts: a solid inner iron core with a radius of 1,220 kilometers (slightly smaller than the Moon), and the outer core, a 2,500-kilometer-thick molten iron shell. The depth, pressure and temperatures of the core do not make it possible to access it by any technical means. That is why there are many questions both about its composition and its mechanisms.

From willow bark to mosquitoes, nature has been a source of vital medications for centuries. But species die-off caused by human activity is putting this at risk

Wild sandalwood populations in Australia have been slowly collapsing for decades. New research found the Western Australian government has been warned repeatedly for a century.

On any given day the water crisis remains invisible yet ever present. Today on the west coast it’s not just evident, it’s tragic.

We’re among the thousands boycotting the UN food summit – it’s been hijacked by corporate interests while the voices of small-scale farmers go unheard

Poverty Point in northern Louisiana is one of the first US civilizations on record, inhabited by a community of Native Americans as early as 1700 BCE. In a new study, researchers have shown these inhabitants to be highly skilled engineers, rather tha

Climate change has been accumulating slowly but relentlessly for decades. The changes might sound small when you hear about them—another tenth of a degree warmer, another centimeter of sea level rise—but seemingly small changes can have big effects on the world around us, especially regionally.

Here’s what’s going on inside their veins

The use of many chemical fumigants in agriculture have been demonstrated to be harmful to human health and the environment and therefore banned from use. Now, in an effort to reduce waste from the agricultural industry and reduce the amounts of harmful chemicals used, researchers have investigated using organic byproducts from beer production and farming as a potential method to disinfest soils, preserve healthy soil microorganisms and increase crop yields.

Our research is deeply concerning because it signals there are no quick fixes to the ongoing fire crisis afflicting Australia, which is being driven by relentless climate change.

Images intended to help open up the outback to mining following World War II instead deliver a lesson from the last generation of Indigenous people to live in the Great Sandy Desert on how to protect life and the land.

There are several ways that surface gravity on Earth could change. We wouldn’t like most of them. If a mini black hole collided with Earth and didn’t pass straight through, it would sink to the planet’s centre. Gravity would soar as the entire planet is pulled into the hole. It would probably get very hot too, so no one would survive to see the final spaghettification as we got within a few kilometres of the hole, when we are pulled apart by intense gravity gradients.
