If renewable switch grass, for example, was burned cleanly enough biomass could join solar, wind, hydro, and thermal energy as sustainable energy replacements in the post fossil fuel era. ARC estimates that an emissions rate of 0.3 grams/hour of PM2.5 would protect air quality in cities and meet the Paris Agreements when replacing natural gas.
Not all that hard to do…
“Earth is likely to cross a critical threshold for global warming within the next decade, and nations will need to make an immediate and drastic shift away from fossil fuels to prevent the planet from overheating dangerously beyond that level, according to a recent report from the Intergovernmental Panel on Climate Change.
… It says that global average temperatures are estimated to rise 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels sometime around ‘the first half of the 2030s,’ as humans continue to burn coal, oil and natural gas.
…Under the 2015 Paris climate agreement, virtually every nation agreed to ‘pursue efforts’ to hold global warming to 1.5 degrees Celsius. Beyond that point, scientists say, the impacts of catastrophic heat waves, flooding, drought, crop failures and species extinction become significantly harder for humanity to handle.” –Brad Plumer reporting in the New York Times, 4/21/23
On the other hand, transitioning to renewability accomplishes an almost universal dream of humanity.
