Letter: Anti-carbon supporters don't follow basic science principles
Drietz says American environmentalists’ proposals are worthless for controlling global warming.
To The Editor:
This is a response to the Dec. 25, 2021 Global Warming letter.
I’ve been writing editorials in opposition to “‘Man-made’ global warming” for over a dozen years. One thing keeps recurring; the ‘anti-carbon’ supporters don’t seem to want to follow up with basic science principles explaining how man’s tiny contribution of CO2 to nature’s huge CO2 budget, forces the entire globe to heat up when it has to go against much more powerful natural processes such as water vapor (a much more prevalent greenhouse gas), solar energy absorption/reflection, volcanism, etc.
Our contribution to the global reservoir of atmospheric CO2 is too small to have any effect. Even a 2020 Bloomberg article said the COVID-19 pandemic brought down air pollution due to drop in fossil fuel usage; but had no effect on rising atmospheric CO2 level.
Look at the NOAA annual mean growth rate of CO2 chart covering 1960 through present at Mauna Loa observatory. We see that it dropped to .28 and .48 ppm for years 1964 and 1992. Did people suddenly burn less coal and oil those years? No, it was Mt. Agung (1963-64) and Mt. Pinatubo (1991-92) blasting about one cubic mile of ash into the air to a height of some 22 miles. This causes a shading/cooling effect on the ocean, which then expels less CO2. Geo-engineers are working on essentially duplicating this shading effect by possibly introducing particulates into the atmosphere to curb the amount of heating from the sun.
Water vapor, a greenhouse gas, traps about 1,300 times more heat than man’s CO2. That’s based on a 1% global atmospheric water vapor content; however, it can at times go up to 4% in places. Even a somewhat small up or down change in the massive quantity of water vapor may release or absorb far more heat, and therefore have more effect on temperature, than would a doubling of our current tiny CO2 level.
Oceans have a huge effect on water vapor level depending on amount of cloud cover blocking the sun’s energy and activity of the 40,000-mile under-sea volcanic mountain chain; very little of it is being monitored.
In summary, American environmentalists’ proposals are worthless for controlling global warming. And if they did have some effect, we need to keep in mind that China produces a lot more CO2 than the U.S. And frankly, we are in no position to tell China what to do, since we are greatly dependent on them to do our manufacturing; they’ll soon be the world’s largest economy.
