> But the melt rate is increasing with increasing average temperatures. Wikipedia quotes a melt of 5 E 11 tonnes in 2019. Perhaps the doubling time is about 10 years? At that rate it'd take about 5,000 years to melt away. At that doubled rate it would take 5,000 years, but if that rate doubles every 10 years, at the rate 10 years from now, it would take 2,500, at the rate 20 years from now 1,250, at the rate 100 years from now about 5.
