This blog is intended to introduce the reader to the scientific data and rational discussion in regards to anthropogenic global warming. I’m an Electronics Engineer & former Principal Investigator with a degree from Rensselaer Polytechnic Institute in Troy, NY. Over my 30-year career I’ve acquired specialized knowledge about the space radiation environment and its effects on semiconductor devices. This knowledge can be applied to help understand Earth’s complex and wonderful climate system from the outside in. You’ll need to find a good Geologist or Vulcanologist to study the climate system from the inside out. And even confining one’s research to the lithosphere, one requires a decent understanding of Oceanography, Marine Biology, Atmospheric Chemistry & Physics, Glaciology, Meteorology, Earth Science and  Botany to appreciate the factors impacting global climate change.

At the present time I work for a company requiring a certain degree of anonymity — sorry, no requests to identify myself more fully can be satisfied at this time. However, I can say my job requires working with many NASA engineers & scientists — including those who study Earth’s climate. Also, I regularly meet with the world’s top scientists at conferences in my area of specialty – space radiation & plasma physics.

Please understand I’m skeptical of the idea that +80 ppm of atmospheric CO2 can drive any measurable climate change. I haven’t heard a rational explanation of the physics:

1) Radiative absorption by CO2 occurs at narrow “windows” (frequency bands) in the infrared spectrum

2) The atmosphere approaches optical saturation with CO2 at levels of just 200 ppm (average)

3) Water vapor (H2O) is far from optically saturated, and exhibits radiative absorption over vast ranges of spectral frequency, including those narrow bands occupied by CO2

4) The maximum solar radiation at the spectral frequencies absorbed by CO2 is only about 10% of Total Solar Insolation (TSI)

5) Since both H2O and CO2 absorb infrared radiation at the same frequencies (albeit, CO2 absorbs 50% more effectively than H2O at one frequency peak) it is reasonable to estimate a maximum of 6% of TSI can be absorbed by CO2

6) The estimate in 5) assumes equal concentrations of H2O and CO2 in the atmosphere; at the present time, accurate estimates of mean atmospheric H2O & CO2 have not been scientifically determined… however, many have suggested H2O averages about 1% (10,000 ppm) and CO2 averages about 385 ppm, based on limited or localized data

7) If average atmospheric H2O concentration is determined to be greater than 1%, then radiative absorption (sometimes referred to as the “Greenhouse Effect”) is likely to be caused almost entirely by H2O, and not by CO2 (10,000 ppm vs. 385 ppm)… nor by any other greenhouse gas (present in concentrations much, much lower than CO2)

In considering whether CO2 is an important factor driving climate change one must recognize there remains considerable scientific debate; when you hear someone assert “the debate is over, and the science is settled” you are listening to political, not scientific arguments. Scientists understand that total CO2 emissions by all human activity represent no more than 25% of the +80 ppm increase in CO2. Rational scientific calculations can show that this constrains the upper limit on global warming due to the burning of fossil fuels, the converting of jungle to farmlands, and the manufacturing of cement (the largest sources of anthropogenic CO2 emissions) to no more than +0.0025 degrees C over 100 years. This figure is not measurable; nor is it distinguishable against a background of natural climate forcing exceeding more than +/- 1.0 degree C over 100 years.
