Upheaval and extinctions linked to magnetic reversal 42,000 years ago

42,000 years ago, a breakdown in Earth’s magnetic field led to environmental catastrophes and mass extinctions.

Watch a Billion Years of Shifting Tectonic Plates Forming Our Continents in 40 Seconds

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 […]

How icebergs really melt — and what this could mean for climate change

(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.

‘Runway Roadkill’ rapidly increasing at airports across the world, UCC study finds

(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.

Human activity forces animals to move 70% further to survive

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.
