He then goes on to discuss the three major factors affecting our earth: raise in land and ocean temperature, extreme rate of melting of ice caps and draining into oceans, and statistics of the skyrocketing extreme weather events in severity, frequency, and intensity.
He then goes on to further discuss the need to replace Arctic sea ice, which is trending down very rapidly. This includes Pauls classic scientific illustration, of the amount of energy needed to melt one kilogram of ice, being equivalent to the amount of energy to raise the resulting 1 kilogram of meltwater to 80 degrees celsius. He then discusses the role of the decline of snow cover, in reflecting radiation.
He then explicates abrupt loss of sanity, the death by 1,000 cuts we witness day after day now, and climate change deniers. He concludes by discussing his unique perspective, as a long term professional educator, as to the views of the young, and the need to connect the dots. Paul’s points towards a tipping point in human behavior. Mentions of Peter Wadhams new book, A Farewell To Ice, and closes with role of Jevons Paradox.
