Good Hope Model April 28: Our first ½ year long Arctic Blue Ocean Event could come as early as 2023. No sea ice for 6 months, in as little as 4 years?

The Good Hope Model, explained further in the YouTube below, has recently gone through quality control updates & control calculations (which you should ALWAYS do to check that your math is right). Instead of trying to build a huge model of the entire planet inside a computer, the Good Hope Model applies 40 years of already registered ice data, or what has already happened, and looks at how rapidly we have been losing ice. Different long & short averages of this decline provide different estimates for the disappearance of Arctic sea ice for 6 consecutive months.
