A Path to Zero Carbon: Comments on the Virginia Energy Plan

The Virginia Energy Plan is currently being updated as required under Virginia Code § 67-201. The plan is updated every four years and covers a ten year period. The Department of Mines, Minerals and Energy is leading the effort and has hosted a number of public input sessions. They also are accepting written comments through Virginia Regulatory Town Hall online forum. Below are the comments made by Zero Carbon’s Dr. Harrison Crecraft at the August 16 public input session at George Mason University.

We have all heard the alarms about greenhouse gases (GHGs) and global warming. I would like to start by offering a bit of geologic perspective. Since the start of the industrial period, CO2 has soared from 290 to 410 ppm. Its timing and isotopic signature leave no question that this spike in CO2 is from burning fossil fuels. At current rates, CO2 will reach 500 ppm within 45 years.

The last time CO2 was at today’s levels was 3 million years ago. Geologically speaking, this is the recent past. At that time, according to a 2017 Yale University report, global temperatures were 4-5°F warmer; the arctic was 20° warmer; and sea levels were at least 60 feet higher. Although the precise response of elevated GHGs on climate is complex and the details are debated, there is no debate about the basic science: elevated heat-trapping gases requires higher global temperatures in order to balance the solar energy input.
