Fiber optics map temperature of Greenland Ice Sheet in unprecedented detail

Tracking changes in huge masses of ice is key to understanding the effects of climate change on the planet, and researchers in Greenland have developed a new tool that takes the accuracy of such measurements to unprecedented levels. The technology uses a mix of fiber-optic cables and laser pulses to gain precise temperature readings from the surface of the Greenland Ice Sheet all the way down to the bottom, offering a clearer picture of the changes taking place in the world's second largest ice sheet.

Surprisingly high mercury levels detected in Greenland glacier meltwater


The Greenland Ice Sheet is associated with a range of environmental issues, but now researchers have discovered a surprising new problem that hadn’t been considered before. Glacial meltwater was found to be unexpectedly high in mercury, which could have consequences for the local fishing industry.

The researchers didn’t specifically set out to study mercury levels – it was just one of many elements they were measuring to determine the quality of the water running off melting glaciers. The team took samples of water from three rivers and two fjords near the ice sheet to study the nutrients being delivered to coastal ecosystems.

Giant diamonds may hold the key to superdeep earthquakes


Earthquakes shouldn’t occur more than 300 kilometers below Earth’s surface, according to most geophysical models. Yet they commonly do—a phenomenon that has mystified seismologists for decades. Now, researchers suggest water carried by tectonic plates shoved beneath continents could be triggering these deep temblors. The find may also explain another marvel: why a huge number of fist-size diamonds form at this depth.

Wow 16 already. It will be his generation and the next to deal with this. What a legacy we've, (Politicians), have left for them.

Earth is trapping ‘unprecedented’ amount of heat, Nasa says


The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an “unprecedented” increase amid the climate crisis.

Scientists from Nasa, the US space agency, and the National Oceanic and Atmospheric Administration (Noaa), reported in a new study that Earth’s “energy imbalance approximately doubled” from 2005 to 2019. The increase was described as “alarming”.
