Earth news stories

For millennia, humans in the high latitudes have been enthralled by auroras—the northern and southern lights. Yet even after all that time, it appears the ethereal, dancing ribbons of light above Earth still hold some secrets.

Fields of rust-colored soil, spindly cassava, small farms and villages dot the landscape. Dust and smoke blur the mountains visible beyond massive Lake Malawi. Here in tropical Africa, you can’t escape the signs of human presence. How far back in time would you need to go in this place to discover an entirely natural environment?

The Brazilian Amazon released nearly 20 percent more carbon dioxide into the atmosphere over the last decade than it absorbed, according to a stunning report that shows humanity can no longer depend on the world’s largest tropical forest to help absorb human-made carbon pollution.

We reveal some of the ways that planet Earth has been changing against the backdrop of a warming world. Here, we look at the effects of global heating on Victoria Falls, one of the natural wonders of the world – and how Sub-Saharan Africa is learning to cope with the climate crisis.

Indigenous Australians have long pointed out that their ancestors have lived on and cared for this continent since time immemorial. Hampered by entrenched misconceptions and outdated curricula, it’s only in recent decades – with discoveries like Mungo Man and Mungo Lady – that science has started to catch up.

Earth’s continents have been leaking nutrients into the ocean for at least 3.7 billion years, new research suggests.

For thousands of years during the last ice age, generations of maritime migrants paddled skin boats eastward across shallow ocean waters from Asia to present-day Alaska.

It’s an unassuming rock, greenish in colour, and just over 4cm in its longest dimension. And yet this little piece of sandstone holds important clues to all our futures.

The Pink Moon – the second largest full moon of 2021 – will light up the night sky shortly before midnight on Monday (April 26), according to NASA.

Radioactive dust deep beneath the ocean waves suggests that Earth is moving through a massive cloud left behind by an exploded star.

As early as 12,000 years ago, nearly three-quarters of land on Earth was inhabited and shaped by human societies, suggesting global biodiversity loss in recent years may have been driven primarily by an intensification of land use rather than by the destruction of previously untouched nature.

Whether they’re made of methane on Saturn’s moon Titan or iron on the exoplanet WASP 78b, alien raindrops behave similarly across the Milky Way. They are always close to the same size, regardless of the liquid they’re made of or the atmosphere they fall in, according to the first generalized physical model of alien rain.
