The climate crisis is melting Greenland down at an astonishing rate, which is creating an opportunity for investors and mining companies who are searching for a trove of critical minerals capable of powering the green energy economy.

Constant monitoring of faulted regions with seismographs and space geodesy measurements can indicate when land deformations are occurring close to the surface. But for subduction zones, much of the deformation occurs deep within Earth, making it difficult to detect from the surface.

It is estimated that more than 80% of Earth’s surface has been shaped by volcanoes. They’ve helped create our mountain ranges, plateaus, and plains, and have helped fertilize the land that we use to grow our crops.

A 4-billion year old piece of Earth’s crust the size of Ireland has been detected beneath Western Australia according to new research. However this piece of crust is not the oldest. The oldest is in the Canadian Shield on the eastern shore of Hudson Bay which is 4.3 billions years old. The Earth is 4.5 billion years old.

A new study shows that we might be able to predict big earthquakes in the near future better than we thought. Attempts were made in the past to predict earthquakes by using signals such as changing water levels or time intervals between earthquakes.

New research shows forest fires are burning twice as much global tree cover as 20 years ago due to climate change. Resulting in blazes claiming an estimated three more million hectares each year – an area the size of Belgium – compared with 2001.

A recent study published in Nature from the University of Cambridge and the University of Birmingham found that there is a general misconception of the lethal threat volcanoes pose to society and planet Earth at large. The study was authored by Michael

Earth’s current largest ocean, the Pacific, covers more than 30% of the planet’s surface, stretching 19,000 kilometers at its widest point between Columbia and the Malay Peninsula. However, this represents only the remnants of the largest ocean in Earth’s history.

Forests around the Earth are transforming at a shocking rate due to climate change, with trees advancing into previously barren tundra in the north while perishing from excessive heat farther south, scientists have found.

Scientists are studying how the amounts of wildfire smoke mixing with clouds over the Arctic Ocean may play a key role in determining how fast the Arctic sea ice cover will shrink during the next few decades, and when it will disappear completely in summer.
