As other major powers find themselves in climate denial or atrophy, China may well boost its power and status by becoming the global energy leader of tomorrow.
The Turnbull government’s flagship energy plan, the National Energy Guarantee, was intended to end a decade-long stalemate on energy and climate policy in Australia. Ironically, since its unveiling in October 2017, the debate has heightened considerably, with the result that the government has now walked away from the emissions-reduction component of the policy.
To cool the world and also boost plant growth, geo-engineered crops might do the trick. But if they work by dimming the sunlight, the plants will suffer.
