"'A great sadness': Venezuela is first Andean country to lose of all its glaciers
Scientists explain the loss of the Humboldt Glacier, the last in the Sierra Nevada, which they believe makes the South American country the first in modern history to lose all its glaciers. "

By measuring microwave polarization, or how these energy waves wiggle in particular directions, the instrument, located in the #Andes mountains of northern #Chile, is probing the history and physics of the universe — from the very first moments to when #galaxies, stars, and planets formed.
Report on one of the earliest known circular plazas in #Andean#SouthAmerica & one of the earliest examples of #megalithic ceremonial #architecture in the Americas. This is constructed of large free-standing & vertically placed megalithic stones - located in #Cajamarca basin of northern #Peruvian#Andes. This construction method has never before been reported in the Andes & is #distinct from other monumental circular plazas in the region.
"The commonly used term “hunter-gatherers” for describing early humans should be revised to “gatherer-hunters” in the context of the Andes in South America, suggests new research led by an #archaeologist.
…analysis of the remains of 24 individuals from burial sites in #Peru shows that early human diets in the #Andes were composed of 80% plant matter and 20% meat."

Living in the shadow of a mountain, it is difficult to pretend that you are bigger than nature, more able to outlast her, with the right to try to conquer and vanquish her.
Would that everybody, especially those who see themselves as "rulers," live in the shadow of a mountain.

Some glacial rivers are turning toxic. Here’s why.
Rory Burford: "When you think of climate change and glaciers, you probably think of melting. But in the Peruvian Andes, that's only half the problem. My PhD project looks at why the rivers are turning acidic and filling up with toxic heavy metals." https://www.youtube.com/watch?v=kfhMKWswnvI#Peru#Andes#Glaciers#Cryosphere#ClimateChange
Dans la sierra du #Pérou se rejoue, dans un rituel festif, la conquête espagnole de l'empire inca. A l'intersection du #politique et du #religieux, mêlant messes, processions, banquets, danses, etc., la performance se répète dans les #Andes depuis le XVIIe siècle.

As some of you know, today is National Hummingbird Day, conveniently scheduled for my birthday this year. So here is another hummingbird, a male Green-crowned Brilliant, from the hummingbird hotspot of the western Andes of Ecuador.
May the air you breathe be good air – fresh, free, crisp, healthy, clean. Not stale, recycled, old, expelled, and trapped. And let the thoughts you think be deep ones – profound, questioning, innovative, daring. Not stale, recycled, old, expelled and trapped.
Huge. Was going to write a summary but the first paragraph does it just fine.
"Ecuadorians have voted in a historic referendum to halt the development of all new oilwells in the Yasuní national park in the Amazon, one of the most biodiverse regions on the planet."
There's nothing like losing yourself in a good book -- a GOOD book, one well written with an interesting story that inspires you to think, wonder, imagine, and dream.
" #Winter#heatwave in #Andes is sign of things to come, scientists warn - Human-caused climate disruption and El Niño push temperature in mountains to 37C.
Exceptional winter heat in the Andean mountains of South America has surged to 37C, prompting local scientists to warn the worst may be yet to come as human-caused climate disruption and El Niño cause havoc across the region.
The heatwave in the central Chilean Andes is melting the snow below 3,000 metres (9,840ft), which will have knock-on effects for people living in downstream valleys who depend on meltwater during the spring and summer.
Tuesday was probably the warmest winter day in northern Chile in 72 years, according to Raul Cordero, a climate scientist at the University of Groningen, who said the 37C recorded at the Vicuña Los Pimientos station in the Coquimbo region was caused by a combination of global heating, El Niño and easterly gusts, known by locals as Terral winds that bring hot, dry weather.
Dozens of meteorological monitoring stations at more than 1,000 metres altitude recorded temperatures above 35C in winter, according to the Extreme Temperatures Around The World blog."
