What will life be like after Arctic Blue-Ocean-Zero: Abrupt Climate System Disruption

Blue Ocean Zero (BO-0; first Sept with essentially zero Arctic sea ice) is ever more likely each year. I chat on when it will occur + dire consequences we can expect. BO+2 years will have 3 months ice-free (Aug-Sept-Oct); BO+6 extends to July and Nov; BO+9 will be ice-free year round. Greenland, alone and exposed, will shed ice like crazy (greatly increasing sea-level rise); the cold centroid will shift from the North Pole to be over Greenland. Jet streams can become quasi-stationary, only shifting with the seasons.

 Where will we live to avoid the worst; how will we grow food? 

Limiting climate change and mitigating its adverse effects is certainly one of the major challenges of today and for decades to come. It will also require cooperation across many disciplines from humanities to engineering and the natural sciences. As a consequence, it is of great importance that a wide array of audiences is equipped with a basic knowledge of the climate system’s fundamental processes and feedbacks. Not only will this promote a better understanding of the Earth system, but will also lead to more informed discussions about climate science and its implications for society and policy decisions.

Climate Dynamics, by Kerry H. Cook, is a short, accessible introductory textbook aimed at undergraduate students. It does not assume prior knowledge in Earth or atmospheric sciences and is thus intended for a broader audience of future engineers, scientists and policymakers. The book has a quantitative approach, which introduces the fundamental equations of the climate system and develops, for instance, a series of simple concept models for the illustration of the greenhouse effect. It is therefore recommended that readers have a basic understanding of calculus and physics. However, pages are never overloaded with equations.

In his testimony August 1 before the Senate Environment and Public Works Committee, climate scientist John Christy revealed the results of his latest work…“since 1960, there have been more all-time cold records set than hot records in each decade.”
