Policy and technology

Who’s to blame for climate change? [link]

Michael Kelly:  until we get a roadmap, net zero is a goal without a plan [link]

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science.
