AGW Claims vs. Truth – 4. Increased Fossil Fuel use and CO2 level

Claim 4. Manmade CO2 levels have been rising rapidly due to increased industrialization and populations since the 1950s. Truth: CO2 levels have been steadily rising along with warming since the Little Ice Age. Recent increases in industrialization and population appear to have contributed to the increase in atmospheric CO2 since the 1950s when fossil fuel… Continue reading AGW Claims vs. Truth – 4.

AGW Claims vs. Truth -3. Water Vapor Magnifies Warming from Carbon Dioxide

Claim 3. Carbon dioxide is important because it has a forcing effect on other factors such as water vapor which magnify warming effects. Truth: Since the atmospheric absorption of CO2 is already near saturation, (see previous post), very little additional heating can take place due to increased CO2. Contrary to AGW advocates, increased water vapor from warming doesn’t stay as… Continue reading AGW Claims vs. Truth -3.

AGW Claims vs Truth – 2b Benefits of Carbon Dioxide

a.) Animals exhale CO2 and breathe in O2, while plants use CO2 for photosynthesis and "exhale" O2. Professional greenhouses often add extra CO2 to increase growth rates. Increased plant growth removes much of the CO2 released into the atmosphere. Between pre-industrial and present times, studies show an average of 15 percent increase in plant growth rates,… Continue reading AGW Claims vs Truth – 2b Benefits of Carbon Dioxide
