The Secondary Reality

Climate change is hard to think about in an emotional sense. There are dark periods of political inaction and hostility, emerging security risks and sheer anxiety of losing natural systems like the Great Barrier Reef.

On the other hand, some climate action initiatives in planning seem to take epic proportions of their own. Massive solar farms in China and Dubai are examples of how gigantic an effort it will have to be to wain billions of people off dirty and polluting energy while lifting hundreds of millions out of poverty. However, electricity is just a part of our energy use and emissions profile. Oil use is growing, and natural gas use is increasing.

Sea ice on both poles recently lost millions of square kilometers in extent.

Meanwhile the rate of physical change is accelerating. Destruction of sea ice in the Arctic Ocean is perhaps the most critical large-scale phenomenon which is currently underway. There is emerging research on how Arctic sea ice loss is already affecting global weather patterns especially over the Northern Hemisphere continents.
