How was global warming discovered?
There was no one discoverer of global warming as such. As is common in science there was a gradual accumulation of evidence by many scientists.
Early discoveries about climate change (American Institute of Physics - the discovery of global warming)
Jean-Baptiste Fourier calculates that the Earth would be far colder if it lacked an atmosphere.
John Tyndall discovers that some gases block infrared radiation. He suggests that changes in the concentration of the gases could bring climate change.
Svante August Arrhenius publishes first calculation of global warming from human emissions of CO2
Thomas Chrowder Chamberlin produces a model for global carbon exchange including feedbacks.
Global warming trend since late 19th century reported.
Milankovitch proposes orbital changes as the cause of ice ages.
Guy Stuart Callendar argues that CO2 greenhouse global warming is underway reviving interest in the question.
First warnings about climate change (Directgov - a history of climate change)
From the late 1950s, carbon dioxide (CO2) measurements were made on a mountain top in Hawaii. Over the next decade, these measurements confirmed that levels of CO2 in the atmosphere were rising year on year. In 1967, an early computer simulation suggested that global temperatures might increase by more than 4 degrees Fahrenheit, depending on CO2 levels.
Improved climate models developed over the next 20 years confirmed the link between CO2 emissions and global warming. Then an ice core from Antarctica first revealed a link between carbon dioxide levels and temperature going back more than 100,000 years. Warnings like these encouraged international action on climate change.
The individual that is considered to be the founder of global warming is Doctor Hansen from the GISS. Prior to his claim of the planet's warming in 1984, the common consensus in the science community was that the planet was steadily cooling. From 1934 until the late eighties, the planet had steady and consistent cooling for the entire period. This ran is stark contrast to the past 10,200 years of steady warming since the last ice age. Total warming before man strted burning his first piece of coal was over eleven degrees C. From 1934 until 1978 we saw almost 0.5 degrees of cooling. This was coupled with our increased use of fossil fuel and the fact that CO2 always follows temperature to provide "proof that man's use of fuel was cooling the planet.
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…
