Lake Eyre Basin contains one of the few pristine river systems left in the world. But new research shows oil and gas activity is extending its tentacles into these fragile environments.
Researchers from the University of Oslo have drilled to the bottom of the Kongsvegen glacier. Find out why and how they are listening to the destabilisation of Arctic glaciers: The MAMMAMIA project.
Injecting reflective particles into the atmosphere won’t immediately cool the entire planet. A new study shows how parts of the US, China and Europe might still see temperatures rising a decade later.
Air Canada and United Airlines both have orders for hybrid electric 30-seaters. An aerospace engineer explains where electrification, hydrogen and sustainable aviation fuels are headed.
Fossil fuel companies are winning the battle on how we talk about natural gas expansion by referring to it as a “bridge fuel” or an essential bridge to the net-zero energy system of the future.
Cement is responsible for more than 8% of global greenhouse gas emissions. Its emissions doubled over the past two decades, and demand is still rising fast.
A fast-growing population – 50% bigger than it was in 1990 – is causing, directly or indirectly, all of Australia’s serious environmental problems. These impacts must be central to decision-making.
The tropics are projected to face almost daily dangerous heat by 2100. And “extremely dangerous” heat that’s almost unheard of today will occur more often in several regions.
President Joe Biden has pledged sweeping action on climate change but struggled to deliver it. A legal scholar explains why a national emergency declaration should be a last resort.
