Moving swiftly on to Zombie Denier Myth 6 - It is/isn't the volcanoes what are doing it to us.
Answer - No its not.
Evidence - Volcanoes emit around 0.3 Gigatonnes of CO2 per year. This is about 1% of human CO2 emissions which is around 26.4 Gigatonnes per year.
Keep up keep up - here come another one....
Zombie Denier Myth 7 - its water vapor thats doing it...
Answer - classic half truth. Water vapour is the most dominant greenhouse gas. Water vapour is also the dominant positive feedback in our climate system and amplifies any warming caused by changes in atmospheric CO2. This positive feedback is why climate is so sensitive to CO2 warming.A warming planet causes more evaporation, more evaporation = more water vapor, which causes more heat retention and therefore more evaporation....
Next up ......surely not....deforestation is a good idea?
But 16% is caused by deforestation, turning peatland and wetlands, over to agriculture or for building on.
So lets cut down on food production and homes to save 16%.
This appears to be an attempted variant of Zombie Denier Myth 4 - 'Our' CO2 is proportionately insignificant compared to natural CO2, so it's not our fault.
See top of this page for answer.
Next we have Zombie Denier Myth 8 - it was hot before and we had high CO2 before and it was all good.
Answer - total rubbish
"To claim that "higher CO2 in the past disproves CO2 warming" is essentially a straw man argument. If climate scientists were claiming CO2 is the only driver of climate, then yes, high CO2 during glacial periods would be problematic. But any climate scientist will tell you CO2 is not the only driver of climate. Climatologist Dana Royer says it best: "the geologic record contains a treasure trove of 'alternative Earths' that allow scientists to study how the various components of the Earth system respond to a range of climatic forcings." Past periods of higher CO2 do not contradict the notion that CO2 warms global temperatures. On the contrary, they confirm the close coupling between CO2 and climate."
Now for a classic that everyone knows and loves - Zombie Denier Myth 9 - The scientists told us in the 1970's we were heading for an ice age.
Answer - no they didn't - and in pictures:

So in fact, the large majority of climate research in the 1970s predicted the Earth would warm as a consequence of CO2. Rather than climate science predicting cooling, the opposite is the case. Most interesting about Peterson's paper is not the debunking of an already well debunked skeptic argument but a succinct history of climate science over the 20th century, describing how scientists from different fields gradually pieced together their diverse findings into a more unified picture of how climate operates.

And finishing with an old favorite - Zombie Denier Myth 10 - Its all natural.
Answer - No its not. Natural climate change in the past proves that climate is sensitive to an energy imbalance. If the planet accumulates heat, global temperatures will go up. Currently, CO2 is imposing an energy imbalance due to the enhanced greenhouse effect. Past climate change actually provides evidence for our climate's sensitivity to CO2.
