42,000 years ago, a breakdown in Earthâs magnetic field led to environmental catastrophes and mass extinctions.
One billion years of Earth’s geological movements have been summarized in a 40-second video, in which the continents and oceans flit about like amorous butterflies while demonstrating just how mobile the surface of the Earth actually is. The history of plate tectonics, the slipping and sliding around of the Earth’s crust and the continents, has […]

(University of Sydney) Iceberg melt is responsible for about half the fresh water entering the ocean from the Antarctic and Greenland ice sheets. Accurately modelling how it enters is important for understanding potential impact on ocean circulation.
(University College Cork ) The number of reported collisions (i.e. strikes) between aircraft and wildlife is increasing globally, with consequences for personnel and passenger safety as well as for industry economics. These are important considerations for airport operators that are obliged to mitigate wildlife hazards at airfields. Incidents involving mammals account for approximately 3-10% of all recorded strikes. However, relatively little research has been conducted on mammal strikes with aircraft outside of the USA.
Scientists have analysed for the first time the amount by which human activity forces animals to alter their movements. What’s surprising is that episodic activity – like hunting, oil pipeline construction, military manoeuvres – seem to have the biggest impact.
In 2019, America recorded the world’s largest decline in energy-related carbon dioxide. But to credit President Trump, would discredit other important Paris Accord signatories, so nothing was said As Trump’s ideological ally, Australia has been forced to pay a price….
Ammonia has sustained humanity since the early 20th century, but its production leaves a huge carbon footprint. Now researchers have found a way to make it 100 per cent renewable.
Though not often a role model for social justice, freedom, or democracy, Saudi Arabia is delivering to the world a worthwhile example of future living: as it’s announced plans to build a revolutionary zero-carbon, zero-traffic city for over a million people, spanning 105 miles and featuring futuristic technology. The Saudi Crown Prince Mohammed bin Salman […]
