Yes, you're missing an important detail about the lifecycle of arctic ice.
Multi-year ice is about 6 years old. There's no 100 year old ice there. Every year it gets slushed, reaches a minimum around September and builds up again. The minima are dropping, btw. Both in extent as in volume.
- refurb 12y agoThere is no 100 year old ice out there" Where are we getting the air samples to determine what CO2 levels from? I thought it was from bubbles trapped in ice that is 100+ years old.
