We need Co2 Everyday items such as Plastic Fuels Detergents Oxgen

Co2 is natural It appears in over 99% of species, without it we would die Without carbon dioxide, there would be no photosynthesis of green plants, and without photosynthesis, we would have no oxygen to breathe and no food to eat

They say Co2 retains heat longer….hmm If you combine gasses of different temperature, convection currents will equalize the temperature of the gas molecules. As the air cools during the night, the temperature of the Nitrogen, Oxygen and CO2 molecules equalize. Therefore, the amount of heat released from the atmosphere into outer space during a twenty four hour cycle would be the same for nitrogen, oxygen and carbon dioxide. Affect on global warming — zero.

Weather is a natural cycle!! Between 1930 and 1970’s temperatures actually dropped slightly. This was not associated with reduction in fossils fuels

Unformatted text preview: emissions in-fact, they were increasing during this period because of rise of factories. Considering that global warming is about greenhouse gases how can this be. There have been continuous ice ages followed by global warming through Earths history Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic). Human activates contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate...
