Well-known climate scientist and Penn State professor Michael Mann argues in a new book that there are many tools for addressing climate change and transitioning to green energy.
Mannâs book, âThe New Climate War: The Fight to Take Back Our Planet,â comes as the countryâs climate policy is expected to change with the Biden administration.
Mann said he thinks the U.S. is in a position to re-establish its global leadership on this issue, and that Joe Biden has indicated he will do that as president.
âHe campaigned on the climate issue, on the climate crisis,â Mann said. âHe has a mandate to act on the climate crisis, and he is incorporating climate action into every single sector of our executive branch now.â
Scientists say major action is needed by 2030 to avoid the worst effects of global warming.
Mann argues in part the U.S. should use a carrot and stick approach â subsidizing renewable energy and using carbon pricing â such as a carbon tax or cap-and-trade policy â to move the country away from fossil fuels.
âYou can do that by leveling the playing field so that renewable energy, which isnât degrading the planet the way fossil fuel energy is, can compete fairly in the market,â Mann said.
Mann said there has also been a trend among some environmentalists to be against market measures, like putting a price on carbon, based in part on the idea that carbon pricing is regressive. But, Mann said, it can be handled in a progressive way, returning revenues to certain lower-income families, for example.
He said some environmentalists donât think a carbon tax is enough. But, there isnât time to recreate the global economy, and itâs one of the tools that can be used.
âWe have to use the tools that are available to us within the context of the existing economy,â Mann said. âCarbon pricing is a big part of that.â
Mann, a distinguished professor of atmospheric science who has served on scientific committees to report on climate change, said climate change canât be denied anymore. He says the fossil fuel industry is moving away from discrediting climate science. Instead, itâs using tactics like focusing on individual behavior rather than policy changes, to protect its interests.
âThe impacts have become so obvious that they canât really deny that climate change is real or human caused anymore, so theyâve turned to more insidious and nefarious means of trying to distract the public and block action,â he said.
Mann said Pennsylvania has tremendous natural resources and is in a position to be a leader in the transition to greener energy. But itâs a top energy-producing state. Fossil-fuel industry groups, along with industry supporters in the state legislature, regularly cite the industryâs importance to jobs and the stateâs overall economy as a reason to oppose climate-related policies.
âThere are potentially a far greater number of jobs to be provided from renewable energy, from wind and solar, than in the largely-automated now fossil fuel industries like natural gas and coal,â he said.
