Potholer54 - Are humans contributing only 3% of CO2 in the atmosphere?

In the video below you will see how climate change deniers twist and change the facts. One person, who may not be a scientist, will read part of a research paper on climate change and misinterpret, maybe on purpose, the facts, which he then puts out on his blog which hundreds of other climate change deniers then reblog, until you get an echo chamber of misinformation.

Climate change deniers say is that mankind is only contributing 3% of the carbon each year into the atmosphere. Now, Potholer54, who is a conservative and a scientist, describes in the video below how climate change deniers twist the facts to suite their agenda. But they are not able counter the climate change science with any real scientific facts or research of their own.

Mankind emits 3% of carbon into to atmosphere each year, but nature only removes 1.5% of it. Most of the carbon in the atmosphere comes from the activities of plants and animals which our planet completely absorbs, but it doesn't absorb that last 1.5% that man produces per year, which goes on to build up in the atmosphere. As the years go by, this Co2 builds up to dangerous levels which now means that the atmosphere has 45% more Co2 than it did before the industrial revolution. It's pretty simple maths, but the climate change deniers prefer not to understand it.

And according to the CDIAC, half of the extra CO2 has been added since the mid 1980s (http://cdiac.ornl.gov/CO2_Emission/ti...), so that means 25,000 Mt. St. Helen-sized eruptions.

It's absurd how climate change deniers can be so stupid!  

Now, the risk of your house burning down is negligible, but we insure against it anyway because it would be devastating if  it did, so I don't understand why climate change deniers would not prefer to take precautions, especially as climate change could end most human life on earth, as well as destroy much of the wealth that people have.

Potholer54 says how there are many opportunities for capitalists to make serious money out of green technology, and this energy  would be much cheaper too, therefore lowering our fuel bills, increasing our standard of living, and making us wealthier. But the grey haired old men who run the fossil feel industry have managed to convince many people on the right that their expensive, dirty fuel is best for them. They're been had - with millions of them conned, and they are poorer too.

3:15 http://www.geocraft.com/WVFossils/gre... (Mar 2 2007) 4:20 -- 68.52 ppm is 18.6% of 368,400, the total content of CO2 in the atmosphere at the time Heib wrote his blog. 18% of 3 trillion tons (total atmospheric CO2) is 558 billion tons. So if an extra 558 billion tons of CO2 has accumulated in the atmosphere from natural sources, that’s equivalent to over 50,000 Mt. St. Helen-sized eruptions (Mt St Helens emitted around 10 million tons of CO2 according to the US Geological Survey -- https://volcanoes.usgs.gov/vhp/gas_cl...). An according to the CDIAC, half of the extra CO2 has been added since the mid 1980s (http://cdiac.ornl.gov/CO2_Emission/ti...), so that means 25,000 Mt. St. Helen-sized eruptions.
