Given the total irrelevance of volcanic aerosols during the period in question, the only very modest effect of fossil fuel emissions and the many inconsistencies governing the data pertaining to solar irradiance, it seems clear that climate science has no meaningful explanation for the considerable warming trend we see in the earlier part of the 20th century — and if that's the case, then there is no reason to assume that the warming we see in the latter part of that century could not also be due to either some as yet unknown natural force, or perhaps simply random drift.

mass (air), where ratio (CO2 / air) = 380 ppm = 380 parts CO2 per 1 million parts of air molecular mass (CO2) = 44 kg / kmol — molecular mass (air) = 28.8 kg / kmol Thus, Mass (CO2) = 3 x 10 ^ 15 kg = 3,000 Gigatons Man - made emissions of CO2 are estimated at 110ppm, which is 28.95 % of the total CO2 and that equals 868 Gigatons = 0.0164 % by mass of the total atmosphere.

A study undertaken by the Australian Conservation Foundation and the University of Sydney supports the fact that the decision whether to drive to the shops or not is not a major factor in reducing emissions: «Shopping habits represent such a large part of greenhouse gas emissions that even if every household switched to renewable energy and stopped driving cars tomorrow, total household emissions would fall by less than 20 percent», the Sydney Morning Herald reports, quoting the study.

CO2 emissions from power generation in 2016 were near 30 - year lows, in large part due to greater use of natural gas.3 And increased use of natural gas in the power generation sector has helped to reduce total CO2 emissions to their lowest level in nearly 25 years.4 This proves that Americans do not have to make the false choice between utilizing our nation's energy resources and protecting the environment.
