I would encourage everyone to review the "Fourth National Climate Assessment" issued last month under The Global Change Research Act (GCRA) of 1990, a law initiated under the Reagan administration. It charged the U.S. Global Change Research Program (USGCRP) with a legal mandate to conduct a scientific assessment on the effects of global change not less frequently than every four years. It is available at https://nca2018.globalchange.gov/chapter/1/. The program is comprised of 13 U.S. government agencies and the assessment preparation was administered by the National Oceanic and Atmospheric Administration (NOAA).
When asked to comment on the assessment's dire warnings (presented by the top experts in his own administration) the president responded that he had read some of it and that he doesn't believe the assessment. If you have any interest in the future of our planet you must consider what prompted his response. With the ongoing revelations of his connections to Russia and Saudi Arabia, is it as simple as him serving his own business interests above our national interests? The science is clear that human activities, especially fossil fuel extraction and combustion, are driving the acceleration of climate change. Does he have a personal motive for taking an unsupportable stance against the assessment delivered by his own administration?
We have been way too late in reacting to this threat to our nation and our world. Now even the small steps that we have taken politically toward addressing the problem are being rolled back. We are rapidly approaching or may already reached tipping points that will drastically alter the livability of our world within a lifetime. Please make your voice heard on this matter and work to save the future of our species.
