When was global warming discovered?
The first serious research conducted on the effect of changes in CO2 levels was in 1896, when Arrhenius completed a laborious numerical computation which suggested that cutting the amount of CO2 in the atmosphere by half could lower the temperature in Europe some 4-5°C (roughly 7-9°F) - that is, to an ice age level. Arrhenius made a calculation for doubling the CO2 in the atmosphere, and estimated it would raise the Earth's temperature some 5-6°C (averaged over all zones of latitude). Arrhenius did not see that as a problem. He figured that if industry continued to burn fuel at the current (1896) rate, it would take perhaps three thousand years for the CO2 level to rise so high. In any case Arrhenius and other researchers were only interested in explaining the Ice Ages. No one seriously believed that global warming was coming. After much criticism, the work of Arrhenius was ignored by the scientific community.
In 1931, an American physicist, E.O. Hulburt, produced calculations supported Arrhenius's estimate that doubling or halving CO2 would bring something like a 4°C rise or fall of surface temperature, but he was a relatively uknown scientist and published his work in a little known Journal.
In 1938 an English engineer, Guy Stewart Callendar, compiled measurements of temperatures from the nineteenth century onwards and confirmed that there was a warming trend. He went on to evaluate old measurements of atmospheric carbon dioxide concentrations and concluded that over the previous hundred years the concentration of the gas had increased by about 10 per cent. Callendar asserted that this could explain the observed warming.
Nevertheless, it was not until the 1970s that scientists began to take the possibility of global warming seriously.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Everything continues to global warming. You breathing, contributes to global warming. Me typing this response contributes to global warming. Toilets contribute to global warming because they are a manufactured product. Anything Manufactured requires energy and materials , all of which contribute in some way, even if minor to global warming.
"Climate Change" and "Global Warming" are not the same, though related. Global Warming causes Climate Change. With Global Warming we understand the warming of the earth's global temperature. That warming has in turn an effect on the earth's global climate and on more localized climates (like the climate of England or Western US).
I do not think that global warming is a myth. There are some who debate the reality of global warming, and others accept that it is happening but deny that humans are substantially responsible for global warming, but these debates simply prove there must be something to it. Global warming is no myth.
1000 years ago there was no global warming, just the normal warming of the earth by the sun. Global warming started when we discovered fossil fuels and started burning them seriously, at the beginning of the Industrial Revolution, about 250 years ago. This burning released age-old carbon dioxide that had been hidden underground for 300 million years. Carbon dioxide is a greenhouse gas, so extra gas in the atmosphere captures more heat, and this is…
