Is this Smoke & Mirrors scientific gobbledygook double-talk....or what?

When warming temperatures hit certain high-altitude ice masses, it sets off a surprising reaction that blows robust cold winds down the slopes, according to the study published December 4 in the journal Nature Geoscience.
The warming climate creates a greater temperature gap between the surrounding air above Himalayan glaciers and the cooler air directly in contact with the ice masses’ surface, explained Francesca Pellicciotti, professor of glaciology at the Institute of Science and Technology Austria and lead author of the study.
“This leads to an increase in turbulent heat exchange at the glacier’s surface and stronger cooling of the surface air mass,” she said in a news release.
As the cool, dry surface air gets cooler and denser, it sinks. The air mass flows down the slopes into the valleys, causing a cooling effect in the glaciers’ lower areas and neighboring ecosystems.
With ice and snow from the mountain range feeding into 12 rivers that provide fresh water to nearly 2 billion people in 16 countries, it’s important to find out whether the Himalayan glaciers can keep up this self-preserving cooling effect as the region faces a likely rise in temperatures over the next few decades.

Scientists uncover a surprising phenomenon in the Himalayas that might be slowing the effects of climate change

Glaciers in the Himalayas are melting rapidly, but a new report showed an astonishing phenomenon in the world’s tallest mountain range could be helping to slow the effects of the global climate crisis.When warming temperatures hit certain high-altitude ice masses, it sets off a surprising reaction that blows robust cold winds down the slopes, according to the study published December 4 in the journal Nature Geoscience.
