Green doubts



To the Editor:

In his letter two weeks ago, John Fehlauer did not choose an individual climate change issue but chose to embrace a wide gambit of topics and imply our government cannot be wrong on climate change. I believe other letter writers are of a different opinion on both parties of government.

And I did not “misquote” Christina Figueres as Fehlauer alleges. Anyone can look it up on Google. My quote, as printed, is accurate.

Letter writer Zack Klyver references the interpretation of what she said.

So, I’ll simply develop my overall position, for which there is peer-reviewed agreement.

CO2 levels are rising and have done so significantly since the Industrial Revolution, more over the last 20 years than the previous several centuries combined.

Greenhouse gases keep the Earth 30 degrees centigrade warmer than without them. CO2 contributes 10 percent, or 3 degrees, to surface temperature. But this energy impact is small; logarithmic. The very first 20 parts per million (ppm) have a greater effect than the following 400.

Doubling pre-industrial 280 ppm levels to 560 ppm would only increase temperatures by 0.3 degrees centigrade.

CO2 is re-greening the planet. That’s a good thing. The Earth can easily tolerate 1,000 ppm CO2. So doubling CO2 levels is not an issue.

There has been no global warming for more than 18 years, so the effect of CO2 on warming is effectively very little – if any.

There are over 200 peer-reviewed papers, published since 2010, demonstrating a solar control of climate.

The net of all these peer-reviewed papers on CO2 is that there is no legitimate reason to restrict CO2 emissions.

We need the least costly and most available energy possible. There is no reason to restrict energy production from coal, natural gas or automobile emissions of CO2.

We can discuss ocean “acidification” another time.
