Doctor Sophie Coulsen and her colleagues explained in a recent paper that, as glacial ice from Greenland, Antarctica and the Arctic Islands melts, Earth’s crust beneath these land masses warps, an impact that can be measured hundreds and perhaps thousands of miles away.
Not only are rising temperatures leading to rising sea levels but most of the increase in energy in the climate system is occurring in the ocean.
Lava samples have revealed a surprising discovery about the geological makeup of the Earth’s crust and could have implications for volcanic eruption early warning systems, a University of Queensland led study has found.
Earth system models are the most important tools for describing the physical state of the Earth including climate models which can predict how it might change in the future under the influence of human activities. AI is used increasingly to help improve these forecasts.
Around 650 million years ago, the Earth entered into the Marinoan glaciation where the entire planet froze. The “Snowball Earth” restricted the evolution of life. But when it warmed, biotic life began to flourish. A research team from Tohoku University has studied rock samples from China to tell us more about this transition.
The Earth’s sprawling ocean ridge system is a result of overturning material in its interior, where boiling temperatures can melt and eject rocks up through the crust, splitting the sea floor and reshaping the planet’s surface over hundreds of millions of years.
International research led by geologists from Curtin University has found that a volcanic region in the Indian Ocean called the Kerguelen Plateau was the worlds most continuously active – erupting for 30 million years – fueled by a constantly moving conveyor belt of magma.
New study suggests a catastrophic supervolcano eruption could be much more likely than currently believed. Current knowledge about the likelihood of eruptions is based on the presence of liquid magma under a volcano, but new research warns “ eruptions can occur even if no liquid magma is found”.
