The UN estimates the global population will pass 8 billion people on Nov. 15, 2022. From the Stone Age to today, here’s how things spiraled out of control.
That’s the big question at the upcoming UN Climate Change Conference, known as COP27, and it’s controversial.
From planting mangroves to dumping minerals in the ocean, there are lots of ideas for ocean carbon dioxide removal – and even more questions.
The energy-intensive process of producing cement and concrete contributes significantly to global warming while depleting resources. Much more sustainable alternatives are being developed.
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.
A new study shows what it would mean for Europe and China, and why the US might not be too excited about the idea.
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.
Pakistan contributes less than one per cent of greenhouse gas emissions, but has disproportionately felt the impact of climate change.
Climate bills in Australia and the US promise progress without carbon taxes or markets. Here’s why.
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 landmark change places Bitcoin and other cryptocurrencies under immense pressure to follow suit.
A field glaciologist explains the changes scientists are now seeing.
Farmers who use little or no fertiliser can use ecological practices to increase their yields.
The emission reduction targets outlined for Canadian fertilizer use will not lead to food shortages and food insecurity.
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.
