Bill Weir is CNN’s Chief Climate Correspondent and the author of Life As We Know It (Can Be). We discuss Carbon Godzilla, decarbonization, and the many existing and accessible technologies to mitigate climate change.

Decarbonization must start with big industry, but there are many ways for individuals to make a difference, too. Clean energy can be had with tax incentives, reducing costs for consumers. Energy efficient homes – passive houses and innovations in heating and cooling – reduce or even eliminate monthly energy bills. At the same time, utility and power companies in the US function as legal monopolies whose primary incentive is to build more infrastructure and raise rates. Fossil fuel companies – despite being the most profitable companies in human history – are still getting billions in direct and indirect subsidies.
