First there is a world of difference between 17% nuclear in the US and the WORLD. Even if the 78,000,000 extra people born each year do nothing but lay there they exhale CO2 and if they eat they fart. Anyway the subject of the article is whether at the last minute countries will step in and implement CSS. I do not believe so and laid out a couple of reasons why they won't and will further elaborate.
1. A number of countries are actuallly looking forward to melting of the polar ice cap opening up shipping lanes and mineral exploration and are filing claims with the UN. China fires up a coal plant every week. Austraila may be shift to clean fuels but is expanding coal export facilities. Historically cheap fuel will be used by someone without a global consenses and this is one world. There are no Sincere efforts at preventing or mitigating carbon emissions. The few facilities so far go to making a few political insiders more wealthy than solving the issue, like peeing against the wind.
2. I grew up in Alaska and have recently returned and noted the Melting Permafrost there and in Russia. The decayed frozen vegetation is now melting releasing CO2. We appear to have passed the tipping point.
3. A 33% population growth over roughly a 22 year period cannot be ignored when considering the demand on the planets resources and whether CSS will implemented or slip in priority.
