"..."One other point I've found interesting is this, there was a rise in global temperatures that occurred during the period from the 1860's to the 1920's. This is long before the Industrial Revolution. What do you suppose contributed to that?"..." Coal Production in England alone: The increase in coal production : 1700 : 2.7 million tonnes 1750 : 4.7 million tonnes 1800 : 10 million tonnes 1850 : 50 million tonnes 1900 : 250 million tonnes historylearningsite.co.uk The burning of coal, of course, releases CO2. The mining of coal releases methane which traps 21 times more heat per molecule than CO2. yosemite.epa.gov see the following (page 4) for estimated atmospheric concentrations yosemite.epa.gov ww

I think perhaps you should study the Industrial Revolution and the history of air pollution a bit more. In fact, this official British site discusses smog as early as the 13th century: UK Air Pollution Air pollution in the UK has been a recognised problem as far back as the 13th century, when the use of coal in London was prohibited on the ground that it was prejudicial to health. During the Industrial Revolution, smog pollution in urban areas became a significant problem, due to the industrial and domestic burning of coal. Today, both urban and rural smog pollution results from the build up of secondary photochemical pollutants such as ozone. Whilst air quality generally has improved during the last 100 years, legislative controls and the introduction of further low emission technology will help to reduce air pollution in the UK still further. ace.mmu.ac.uk
