"I find alarmist wailing about "tipping points" hilarious.
The Klimate Katastrophe (KK) is always upon us, until it isn't. E.g., the planet ha been a decade away from the KK for at least 50 years.
Here's another tipping point.
From the actual paper: "We find that Greenland ice imbalance with the recent (2000–2019) climate commits at least 274 ± 68 mm SLR from 59 ± 15 × 103 km2 ice retreat, equivalent to 3.3 ± 0.9% volume loss, regardless of twenty-first-century climate pathways." So we are already past any sort of tipping point they envisioned. Their paper does not forecast a time period for this, but when asked, they gave a SWAG of 78 – 128 years. To compare, satellite data indicate sea level is rising very linearly at 4.0 ± 0.3 mm/year. At that rate, it takes 68, not 78, years to rise 274 mm. I notice they only studied Greenland & did not consider net effects of Antarctica.
But if they are correct, according to their own conclusion, it really does not matter. The ice gonna do what it's gonna do "regardless of twenty-first-century climate pathways."
