Environmental stability on Earth allowed marine biodiversity to flourish

by

Modern ocean biodiversity, which is at its highest level ever, was achieved through long-term stability of the location of so-called biodiversity hotspots, regions of especially high numbers of species, scientists have found. The findings, published in Nature, were reached through a pioneering model that reconstructs the diversity of marine animals from their origin – some … Read more…

Plate tectonic carbon cycle explains how Earth maintains a Goldilocks climate

by

Earth’s hot and cold climates driven by tectonic plate speeds A new study has revealed how the plate tectonic carbon cycle maintains a “Goldilocks climate” on Earth that is neither too hot nor too cold. It is now established that CO2 emissions from burning fossil fuels are driving atmospheric CO2 above 400 parts per million … Read more…

Groundwater ‘superhighway’ modelled along Australia’s east coast

by

When floodwaters recede, where do they go? By Loren Smith University of Sydney researchers have modelled water-storing aquifers that perform a natural balancing act: they absorb water during floods and supply water during drought. Yet human intervention is limiting their function. University of Sydney researchers have identified a groundwater ‘superhighway’ along Australia’s east coast. Stretching from … Read more…

A journey across the Atlantic seafloor

by

A journey across the Atlantic seafloor More than two thirds of our planet are covered by water. What lies underneath is a mystery – only 20 percent of the sea floor has been explored in detail. But hasn’t it always appealed to you, this underwater world with all its mysteries? Then join us for a … Read more…

When the Earth warms, the ocean speeds up

by

Sixty-six million years of geological data suggests that heating makes ocean currents stronger. By Ellen McPhiddian, Cosmos Ocean currents play a big role in floods, droughts, and other large-scale weather patterns. We know that ocean circulation will be affected by global warming – but figuring out exactly how it will be affected is much more difficult. Will there be … Read more…

Global warming speeds up currents in the ocean’s abyss

by

University of Sydney media release University of Sydney scientists have used the geological record of the deep sea to discover that past global warming has sped up deep ocean circulation. This is one of the missing links for predicting how future climate change may affect heat and carbon capture by the oceans. Circulation of the … Read more…

Volcanoes acted as a safety valve for Earth’s long-term climate

by

Volcanoes acted as a safety valve for Earth’s long-term climate The natural weathering of rocks on Earth’s surface over time is a crucial process for removing CO2 from the atmosphere Researchers have now used artificial intelligence to study interactions between land, sea and the atmosphere to determine the biggest drivers of this process over the … Read more…

World Economic Forum: Watch how today’s continents were formed over one billion years – in just 40 seconds

by

The plate tectonic theory says that Earth’s surface is made up of slabs of rock that are slowly shifting right under our feet. Because of this constant movement, today’s Earth looks a lot different from what it did millions of years ago. In 1912, German scientist Alfred Wegener proposed that Earth’s continents once formed a … Read more…

Earth-moving research charts one billion years of tectonic plate movement

by

New research shows how the earth’s tectonic plates have shifted over the last billion years. Tectonic plates are irregular-shaped slabs of solid rock which can vary massively in size from a few hundred to thousands of kilometres across. Heat from radioactive processes within the planet’s interior causes the plates to shift. And this movement creates … Read more…
