Letters: Calls president’s behavior abhorrent, unpresidential; asserts CO2′s role, global warming in general overstated

How can anyone continue to support this president?

I have been sitting on the sidelines for the over 2 1/2 years during the current president’s time in the White House. No longer can I remain silent. It started with his questioning of the reporting on the size of the crowd for his inauguration.

What has followed is a blurb of his un-American behavior, beginning with the Muslim ban, his sparring with Gold Star parents, his inhumane treatment of children at the Mexican border, his rhetoric criticizing a federal judge with Mexican heritage, his reprehensible comments following Charlottesville, his thoughtless conduct throwing paper towels to the victims suffering in the aftermath of Hurricane Maria in Puerto Rico, and his claim that he was doing to drain the swamp while a constant turnover of cabinet members and staff who were never vetted has prevailed.

His “love affair” with Kim and Putin is unexplainable. He was never “a fan" of Sen. John McCain and keeps telling us this well after the senator’s death. He is still obsessed with Hillary Clinton, who he defeated nearly three years ago. He mentions her numerous times at every one of his rallies.

He has railed against four U.S. representatives, telling them to go back were they came from (saying they should "go back and help fix the totally broken and crime infested places from which they came”). These are duly elected members of the U.S. Congress and are American citizens. They just happen to not be Caucasian. He has attacked Rep. Elijah Cummings. In response to recent mass shootings he continues to flip-flop on background checks to help prevent guns from falling into the wrong hands. And now that his economy is showing signs of weakness, he attempted to change the narrative by saying he wants to buy Greenland and insulting the president of Denmark in the process.

His rhetoric is mean-spirited and hurtful, and certainly not presidential. How is it possible for any clear-thinking American to continue to support a man who has behaved in such an abhorrent manner?

Carbon dioxide’s impact, global warming overstated

Let’s take a closer look at carbon dioxide, currently Public Enemy Number One! It’s one of several prominent greenhouse gases. They are; nitrous oxide, methane, ozone, chlorofluorocarbons and water vapor. All have been labeled with GWP ratings (global warming potential). Strengths vary, but at sea level CO2 has a rating of 1, Methane is rated 25 times stronger, water vapor is 45 times stronger, nitrous oxide 300 times stronger, ozone is 1,000 times stronger and chlorofluorocarbons are generally 10,000 times stronger. Good thing CO2 is the most abundant, isn’t it?

Now CO2, among others mentioned, is heavier than air. Highest concentrations are found at or near sea level. As you ascend it becomes ever more rarified. Due to atmospheric mixing (our weather) concentrations are highly variable. Rest assured, however, the major media only publish readings taken from the lowest feasible elevations.

Take a look at our 20th century. During this period mankind set out to do his utmost to increase CO2 levels globally. Along with the natural progression of industry, we engaged in the Balkan Wars, WWI, WWII, the Korean War, the Vietnam War, the first Gulf War plus numerous civil wars and conflicts. This of course caused untold amounts of CO2 and pollutants to be released into our atmosphere worldwide from the destruction of war. So, how far did we move the needle? In 1900, CO2 registered .0296 ppm (parts per million of atmospheric volume) or .0296 hundredths of 1% by volume. At present level, .0410 ppm we pushed the needle a whopping 1.14 hundredths of 1% by volume.

Some 90% of global warming results from water vapor and cloud concentrations. We are told that CO2 is a great magnifier of effects that water vapor produces. We are told that since the Industrial Revolution of the 19th century CO2 has risen by 38%. Yet in that same duration, atmospheric water vapor has risen just 0.3% overall. Space here limits what I can write. All of my data presented, however, is readily available with some objective research. In the 4.6 billion-year lifetime of Earth, I find it very hard to believe the last 150 years are by far the most crucial time span in history for the fate of life on our planet.
