One can tell the depths of ignorance or dishonesty in a poster when they start the yap-yap about how miniscule man's CO2 emissions are compared to natures. Of course, they just happen to fail to mention that nature is absorbing more CO2 than it is emitting. At least for the present.

Humans are raising CO2 levels 2
When you look through the many arguments from
global warming ‘skeptics’, a pattern emerges. They
tend to focus on small pieces of the puzzle while
neglecting the bigger picture. A good example of this
is the argument that human carbon dioxide (CO2 )
emissions are tiny compared to natural emissions.
The argument goes like this. Each year, we send over
20 billion tonnes of CO2 into the atmosphere. Natural
emissions come from plants breathing out CO2 and
outgassing from the ocean. Natural emissions add
up to 776 billion tonnes per year. Without a full
understanding of the carbon cycle, our emissions
seem tiny when compared to nature’s contribution.
CO2 and huge amounts of
CO2 dissolve into the
ocean. Nature absorbs 788
billion tonnes every year.
Natural absorptions roughly
balance natural emissions.
What we do is upset the
balance. While some of our
CO2 is being absorbed by
the ocean and land plants, around half of our CO2
emissions remain in the air.
