The Sun Versus CO2 as the Cause of Climate Change Projected to 2050

The current controversy over the cause of increasing global temperatures since the middle of the 20th century comes from the IPCC First Assessment Report issued in 1990. The report states rising carbon dioxide (CO2) warms the air, thereby holding more of the significant warming gas, water vapor. This additional water vapor feeds back to amplify the warming by CO2. The IPCC has continually promoted this concept in its reports since 1990. Up-to-date science proves the IPCC concept is faulty. Scientists discovered that when the Sun's energy output changes, it impacts the Earth's temperature, and it does this cyclically. Current, reliable evidence shows the Earth has just come through a warm period. It is now in the early stages of cooling that might be similar to the Dalton Minimum and last for three or four decades. Average temperatures can drop by up to 1.5oC and increase the rate of crop failures that have already started. It won't be easy to maintain the benefits of the recent warm phase of the Sun during the upcoming solar minimum.
