Blue Ocean Event (no ice in the Arctic) to happen in a few years will then increase global warming by 40%

the latest cutting edge science from late 2019 expects that a Blue-Ocean State (zero Arctic sea ice) in summer would heat the overall planet the equivalence of 25 years of global warming or 1 Trillion tons of CO2. Putting this into context, as of 2016 an estimated 2.4 Trillion tons has been emitted since the preindustrial period; due to both fossil fuel combustion (1.54 Trillion tons) and land use changes (0.82 Trillion tons). It becomes glaringly obvious that we will blow through 1.5C and 2C Paris safety targets when this happens, not to mention methane and Greenland vulnerabilities.
