Comparison of CO2 levels with the Pliocene is Flawed

Faulty Comparison of CO2 levels with the Pliocene Era

Here is a post from linkedin by a brainwashed person

NOAA records new carbon dioxide peak - near 420 parts per million.

"The atmospheric burden of CO2 is now comparable to where it was during the Pliocene Climatic Optimum, between 4.1 and 4.5 million years ago, when CO2 was close to, or above 400 ppm. During that time, sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate large forests occupied areas of the Arctic that are now tundra."

The destabilising impacts of climate change are likely to be far reaching, affecting many parts of the global economy in ways not fully understood right now. While it is easy to point fingers at major GHG contributors, it is up to the entire global community to work on solutions to the rising concentration of atmospheric CO2.[1]

Assumptions and facts


This is the sort of faulty science that is behind all parts of the climate change fiasco. Things are deliberately left out and others are deliberately misinterpreted. If the perpetrators really thought that climate change was accelerating and was man-made, then why are they doctoring the science? Why are they fudging the evidence? Why run a witch hunt on non-believers? Why try to brainwash the young, gullible minds with weapons like Greta Thunderbird?

Why not let true science do the talking? If you felt that this was a little hard-nosed, there is a Softer version here.
