Net Zero? Then Drop Dead Emeritus Professor Ian Plimer on carbon dioxide, net zero, and the politics of climate debate. In this clip, Plimer delivers a blunt critique of the UK’s approach to net zero, arguing that carbon dioxide has been wrongly demonised despite being essential to life on Earth. He points out that humans inhale air containing around 0.04% #co2 and exhale far higher concentrations through normal metabolism, using that comparison to mock the idea of reaching “net zero” in absolute terms.Plimer goes on to describe carbon dioxide as a long-standing planetary gas, tracing its role through Earth’s atmospheric history and arguing that periods with much higher CO2 levels also saw thriving life. His wider point is that CO2 is routinely framed as a danger without equal emphasis on its role in plant growth and the biological systems that sustain life.Whatever your view on climate policy, this is the kind of argument that remains highly controversial — and central to the wider debate around energy, environment, and the future of UK policy. https://www.facebook.com/share/v/18duj3PC87/
