Nature: Warming of +1.5 °C is too high for polar ice sheets

"...Mass loss from ice sheets in Greenland and Antarctica has quadrupled since the 1990s and now represents the dominant source of global mean sea-level rise from the cryosphere. This has raised concerns about their future stability and focussed attention on the global mean temperature thresholds that might trigger more rapid retreat or even collapse..."

NatureWarming of +1.5 °C is too high for polar ice sheets - Communications Earth & EnvironmentWarming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, meaning that only a return to +1 °C or lower will avoid extensive loss and damage to coastal populations, according to a synthesis of recent evidence.

Farmer’s market, got some “cheesy taco” flavored popcorn and a chocolate/ mocha whoopie pie. That’s still in the fridge bc I found the cup of Mister Softee was just five bucks. Seen dripping down my hand in this quick photo. I made a trench or moat to buy time to eat the tip in the sun.
The #taco #popcorn is pretty good, actually. It’s heavy on #paprika but I saw that coming.

Arctic Melt

Temperatures in the Arctic are rising faster than elsewhere, triggering more and more melting. Photographer Scott Portelli captured a melting ice shelf protruding into the ocean in this aerial image. Across the top of the frozen landscape, streams and rivers cut through the ice, leading to waterfalls that flood the nearby ocean with freshwater. This meltwater will do more than raise ocean levels; it changes temperature and salinity in these regions, disrupting the convection that keeps our planet healthy. (Image credit: S.

“Visions in Ice”

The glittering blue interior of an ice cave sparkles in this award-winning image by photographer Yasmin Namini. The cave is underneath Iceland’s Vatnajokull Glacier. Notice the deep scallops carved into the lower wall. This shape is common in melting and dissolution processes. It is unavoidable for flat surfaces exposed to a melting/dissolving flow.

HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."
