For much of the 65,000 years of Australia’s human history, the now-submerged northwest continental shelf connected the Kimberley and western Arnhem Land. This vast, habitable realm covered nearly 390,000 square kilometers, an area one-and-a-half times larger than New Zealand is today. It was likely a single cultural zone, with similarities in ground stone-axe technology, styles ...
The Northern Lights, also known as the Aurora Borealis, present a mesmerizing display of lights, painting the sky with hues of pink and pale green. This natural phenomenon results from the collision of charged particles from the Sun with Earth’s atmosphere, creating unpredictable light forms like patches, arcs, and shooting beams. Witnessing the Northern Lights ...
Online platforms are awash with ads for so-called “green” products. Power companies are “carbon neutral.” Electronics are “for the planet.” Clothing is “circular” and travel is “sustainable.” Or are they? Our study of more than 8,000 ads served more than 20,000 times in people’s Facebook feeds found many such claims are vague, meaningless, or unsubstantiated ...
Earth’s surface is the living skin of our planet — it connects the physical, chemical, and biological systems and their diversity. Over geological time, this surface evolves. Rivers fragment the landscape into an environmentally diverse range of habitats. These rivers also transfer sediments from the mountains to the continental plains and ultimately the oceans. The ...
A complex web of interdependence exists between the various organisms that comprise an ecosystem, such as seals. Earth’s rich biodiversity is essential to the planet’s continued existence. Therefore, the loss of even a single species can have far-reaching effects on the biosphere. Some species become extinct because of human interference, specifically deforestation and destroying their ...
In a world where progress often comes at the cost of nature, the story of the pear tree in Cubbington, Warwickshire, in England, is remarkable. For over 250 years, this ancient pear tree has been a source of beauty and inspiration, standing tall against the changing times. However, when the HS2 rail line was announced, ...
After years of discussion, international negotiations on a global plastics treaty resume this week in Nairobi, Kenya, at the UN Environment Programme headquarters. The focus will be how to deal with the world’s plastic pollution problem. The third session of the UN Intergovernmental Negotiating Committee on Plastic Pollution will take place from today until Sunday ...
Australia is famous for its diverse and unique marsupials and infamous for its world-leading rate of mammal extinctions. In our latest research, we have added new names to the list of Australian marsupials — and at the same time, new entries to the grim catalogue of species driven to extinction since European colonisation. Our new ...
It might sound like science fiction, but “marine cloud brightening” is being seriously considered as a way to shield parts of the ocean from extreme heat. We’re using water cannons to spray seawater into the sky. This causes brighter, whiter clouds to form. These low marine clouds reflect sunlight away from the ocean’s surface, protecting ...
In 2020, Oxford-based philosopher Toby Ord published a book called The Precipice about the risk of human extinction. He put the chances of “existential catastrophe” for our species during the next century at one in six. It’s quite a specific number and an alarming one. The claim drew headlines at the time and has been ...
