Greenland just lost 105 billion tonnes of ice in a single season — and scientists say the scarier part isn't the number, it's why it's happening faster now.
This wasn't even the worst year on record.
It was middle-of-the-pack.
That's the problem.
Because even an "average" bad year is now revealing something new — the ice itself is changing colour.
Fresh snow is a mirror.
It bounces sunlight straight back into space.
But satellites are now spotting huge patches of Greenland where that mirror is gone.
What's left underneath?
🔥 Wildfire soot, carried thousands of km from distant continents
🌪️ Dust deposits building up year after year
💧 Pools of dark meltwater sitting on the surface
And dark stuff doesn't reflect heat.
It drinks it.
Here's the twist that has researchers worried.
More melt → exposes more dark ice.
More dark ice → absorbs more sun.
More absorption → even more melt.
Scientists call it the melt-albedo feedback.
Think of it like a snowball rolling downhill — except this one gets darker, hotter, and faster the longer it rolls.
2024–25 wasn't a one-off shock.
It marks 29 straight years of Greenland losing more ice than it gains.
And this year, melting didn't politely stop when summer ended — it dragged on into September, weeks after Greenland's ice usually calls it quits.
August smoke drifting in from wildfires clear across North America even dimmed the ice's reflectivity in real time.
Weather thousands of kilometres away is now writing Greenland's melt story.
This isn't a distant, frozen problem.
Meltwater from Greenland flows straight into the North Atlantic — shaping ocean currents, sea levels, and weather patterns far from the ice itself.
Models suggest the coldest, most stable northern parts of Greenland could see the sharpest melt increases later this century.
The part of the ice sheet everyone assumed was safe.
⚡ Turns out, the ice sheet isn't just a victim of a warming planet.
It's building its own engine to melt faster.
That's all for now!
