Crawford Lake, Canada, Chosen as the Primary Marker to Identify the Start of the Anthropocene Epoch

An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global ...

Scientists Discover 36-Million-Year Geological Cycle That Drives Biodiversity

Movement in the Earth's tectonic plates indirectly triggers bursts of biodiversity in 36 million-year cycles by forcing sea levels to rise and fall, new research has ...

Global Cooling Caused Diversity of Species in Orchids, Confirms Study

Research shows global cooling of the climate 10 million years ago led to an explosion of diversity in terrestrial ...

Why the Day Is 24 Hours Long: Astrophysicists Reveal Why Earth's Day Was a Constant 19.5 Hours for Over a Billion Years

Astrophysicists have revealed how the slow and steady lengthening of Earth's day caused by the tidal pull of the moon was halted for over a billion years. They show that from approximately two billion years ago until 600 million years ago, an ...

We've Pumped So Much Groundwater That We've Nudged Earth's Spin

By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, ...

Massive Underwater Plateau Near Solomon Islands Is Younger and Its Eruption Was More Protracted Than Previously Thought

The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, ...

Earth Was Created Much Faster Than We Thought: This Makes the Chance of Finding Other Habitable Planets in the Universe More Likely

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that ...
