Guest post: Greenland ice sheet shrinks for 30th year in a row
Thirty years. That means every year since 1995, Greenland has ended up with less ice than it started with. A child born when the streak began is now an adult who has never known a year of net gain. That framing is worth sitting with.
The numbers matter, but the mechanism matters more. The melt is accelerating as warmer air and ocean water eat the ice from above and below. Each year builds on the last, and the feedback loops are what keep me up at night. Darker, wetter ice absorbs more sunlight. Thinner ice calves faster. The process compounds.
What I'd want to know next is how much of this year's loss came from surface melt versus calving events, because that difference tells us about the near-term trajectory. The 30-year mark is a clean headline, but the messy details underneath are where the real story lives. We have passed the point of detached alarm, and this is now a permanent feature of the planet we are handing to the next generation.
