Climate change is nothing new (Greer)

Overwhelming scientific evidence shows earth’s climate has always changed, and correlates with the sun, not human fossil fuel use or CO2 emissions.
Global temperatures cycled as much as 8 to 12 degrees Celsius as the earth cycled between long ice ages and short warm periods many times in the last 2.5 million years.
Smaller variations occurred in the last 10,000 years since the end of the last ice age, with temperatures often warmer than today, long before human emissions.
CO2 is not a foreign substance but is natural and essential to life on earth. Annual World human CO2 emissions of about 33 billion tons may sound like a lot but is a tiny 0.02 percent of the 150,000 billion tons already in nature, according to the UN IPCC.
What happens to the human generated CO2? It simply becomes plant food and part of the natural carbon cycle. It is therefore not surprising that no study has ever positively linked any climate change to man-made CO2. Being without scientific evidence, climate alarmists and politicians must rely on false claims of consensus and baseless claims of catastrophe in quest of money, power and control.

Climate change science – letter of Chad Tolman, Wilmington, published by News Journal on 1/5/17, makes three claims: (1) “His [Greer’s’] statements, including that Earth’s climate ‘correlates with the sun, not human fossil fuel use or CO2 emissions,’ and ‘no study has positively linked any climate change to man-made CO2,’ show that [Greer] is out of touch with modern climate science.” (2) Tolman has “a PhD in physical chemistry from UC Berkley,” has “studied, written and taught (including at UD) about climate science for over 25 years,” and can “assure you that more than 97 percent of climate scientists agree that the Earth’s climates are rapidly changing.” (3) “The major cause is growing emissions of CO2 from human burning of fossil fuels,” wherefore “carbon emissions must be reduced as rapidly as possible.” Mr. Tolman avoids claiming an overwhelming scientific consensus for the third point, which is the crux of the issue since almost everyone agrees that climate change occurs. Also, he ignores the longer-term record, which shows climate change was going on eons before human combustion of fossil fuels became a material factor.
