Did the #snowballEarth give complex life a boost?
Planet-wide #glaciers may have filled the #oceans with mineral nutrients.
As massive glaciers scratched and scarred #Earth’s rocky surface, they freed less-common minerals, which were later flushed into the seas as the ice melted into giant glacial rivers. These minerals in turn may have spurred nutrient cycling in the oceans, boosting the metabolism of microbial life.

The next generation of Bakonzo people will be profoundly impacted by the loss of glaciers. Masereka says: ‘I will tell my son it was very beautiful to have snow on the Rwenzori for our livelihood … it will be unfortunate, but I will encourage him to involve himself in conservation-related activities as an alternative to the snow, which was our resource in our time’

It’s getting hard to put a smile on my face these days. Lots of negative nonsense all abound. But it’s pictures like these, that help remind me that there is still good in this world.

“How could the world go back to the way it was, when so much bad had happened? But in the end, it’s only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines, it will shine out the clearer.”

Melting #glaciers caused almost 2cm of #sealevelrise this century, study reveals
Decades-long research shows world’s glaciers collectively lost 6.542tn tonnes of #ice between 2000 and 2023, causing an 18mm (0.7in) rise in global #sealevel.
Regional losses were highly variable; the Antarctic and subantarctic islands lost 2% of their volume but central Europe’s glaciers lost 39%.
36% more ice having melted between 2012 and 2023 compared with the previous decade.

"#China’s glacier area has shrunk by 26% since 1960 due to rapid global warming, with 7,000 small #glaciers disappearing completely and glacial retreat intensifying in recent years, official data released in March showed.

The dramatic ice loss, from the Arctic to the Alps, from South America to the Tibetan Plateau, is expected to accelerate as #ClimateChange, caused by the burning of fossil fuels, pushes global temperatures higher."

These microbes are far from typical, having genes that are adapted to extreme cold, scarce nutrients and oscillation between intense sunlight in summer and snow-covered darkness of winter.

Some Tibetan glaciers contain microorganisms that can produce antibiotics.

Just like oceans and rainforests, glaciers and ice sheets are teeming with life. The glacial biome is composed mainly of microorganisms, and it is visible to the human eye only during colourful algal blooms. This microscopic ecosystem contains members of all three domains of life — archaea, bacteria and eukaryotes.
