Blockbuster: Billions on wind, solar, batteries, has only cut Australian emissions 4% in 20 years (trees did the other 24%!) Not only has all the money poured into emissions reduction been trivially effective, the second graph shows why all our efforts in reducing emissions in agriculture, industry, transport and electricity are like climbing Mount Impossible. But biology evolved to “reduce carbon emissions,” and removing a few bottlenecks lets the natural carbon-reduction-bio-machine rip. The national accounts are only for man-made (anthropogenic) carbon emissions. The aim here is not to reduce carbon emissions as cheaply and realistically as possible, or they’d be honest about what works and what doesn’t.
