Well, it’s “official” now. The Trump administration has stated that human-caused global warming is real (see the latest National Climate Assessment), even though the president remains skeptical. More dire and catastrophic events are predicted unless mitigating action is taken to slow greenhouse gas emissions.
The scientific community overwhelmingly has viewed HCGW as “settled science.” Carbon dioxide levels are now nearing 410 parts per million, the highest level ever recorded in the history of the planet, going back hundreds of thousands of years. The rapidly increasing CO2 levels correlate with increased worldwide fossil fuel use.
Climatologists are alarmed at the rapid and unprecedented changes they are seeing.
