I believe the sun, The earths magnetic field the shifting of the magnetic pole and the magnetic field decreasing, all have a major effect on global
warming and cooling.
In the last 40 years the sunspot activity has matched global warming hockey stick.
I also believe Methane, Ozone, Fluorocarbons, and water vapor also has a larger effect.
I do NOT believe CO2 is the only or greatest cause.
CO2 is a minor cause along with the above.
Controlling CO2 will do little to nothing to stop global warming/climate change.
but controlling CO2 does give the environmentalist what THEY want.
to industrialize and control the world.
Methane is emitted from livestock, agricultural processes, and organic waste decay. It is also created during the production and transport of coal,
natural gas and oil. The IPCC report gives methane a GWP of 62 over a 20 year period and its average atmospheric lifetime is 12 years. From these
figures it can be seen that methane is a powerful greenhouse gas,
The ozone layer not only protects the earth from ultraviolet rays, it also acts as a natural greenhouse gas, but a study by the European Union
entitled “Tropospheric Ozone in EU - The consolidated report” found that the production of ground level ozone has risen dramatically since the
industrial revolution. This ozone is formed by the action of sunlight on hydrocarbons and nitrous oxide from the burning of fossil fuels. This ozone
eventually finds its way to the troposphere and helps increase the greenhouse effect.
Although the ozone depleting chlorofluorocarbons (CFC) were phased out under the “Montreal Protocol” the newer hydrofluorocarbon (HFC) and
perfluorocarbon (PFC), brought in to replace them, are some of the strongest greenhouse gases known to man. In the IPCC report they have GWPs ranging
from 300 to 10,000 with lifetimes of hundreds of years. These powerful greenhouse gases are used extensively in refrigeration and air conditioning and
can enter the atmosphere when the units are damaged or being decommissioned.
