He reasoned some of that energy must be held within the atmosphere and not return to space, in order to keep the Earth warm. He proposed that Earth’s thin covering of air—its atmosphere—acts the way a glass greenhouse would. Energy enters through the glass walls, but is then trapped inside, much like a warm greenhouse.]]> 2021-02-08 14:04:58 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176949025 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176955455 Laboratory tests showed that coal gas containing CO2, methane and volatile hydrocarbons was especially effective at absorbing energy. ]]> 2021-02-08 14:06:04 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176955455 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176956181 A Swedish Chemist, Svante Arrhenius, began researching how decreasing CO2 levels might be able to cool the earth. This chemist was ahead of his time, proving that if CO2 levels were to be doubled, temperatures would increase by 9 degrees F. Modern climate researches have looked at his studies and claimed them to be accurate and not far off to today.

Guy Steward Callendar, a British engineer, made aware of how warm the United States and North Atlantic Region had become due to the Industrial Revolution. He continued to argue that the greenhouse effect was underway into the 1960s but was met with skepticism.  ]]> 2021-02-08 14:06:50 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176960059 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176965612 Established the first greenhouse gas monitoring station (Scripps Institution of Oceanography ) on top of Hawaii’s Mauna Loa Observatory. Data revealed what would become known as the “Keeling Curve” which is an upward, tooth-shaped curve graph showing a steady rise in CO2 levels, along with short, jagged up-and-down levels of the gas produced by repeated wintering and greening of the Northern Hemisphere.]]> 2021-02-08 14:07:41 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176965612 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176968956 Became one of the first developers of groundbreaking computer models. Later, he incorporated surface hydrology (oceans and sea ice) and vegetation into the climate models along with the atmospheric data. He had presidential appointments under the Carter, Reagan, Clinton, and Bush administrations. He was awarded the National Medal of Science by President Obama "for his development and use of global climate models to understand climate and explain the role of human activities and natural processes in the Earth's climate system and for his work to support a diverse science and engineering workforce."]]> 2021-02-08 14:08:13 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176968956 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176974003 During the 1970s, there was a "Cooling period." where some scientists thought that pollution could block the sunlight and that is why the earth was becoming cooler A Time magazine article came out in 1974 called "Another Ice Age?" where it described how it could be cooler. Eventually, the cooling period ended and CO2 was still very prevalent in the atmosphere]]> 2021-02-08 14:09:04 UTC https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176974003 courtneywhite10 https://padlet.com/courtneywhite10/4iwaz9zp6rt2hzvz/wish/1176976012 The beginning of the 1980's marked a drastic increase in global temperatures. That summer was the hottest on record with many widespread droughts and wildfires occurring in the U.S. Scientists along with the media begin to pay closer attention to the issue at hand. NASA scientist James Hansen spoke that he was 99% sure global warming was upon us.

It was founded in an effort to provide a scientific understanding of climate change and its effects on politics and the environment. The creation of this organization lead to much needed research on climate change as its impacts became more dire and clear. Researchers were able to predict severe heat waves, hurricanes, droughts, and rising sea levels. - Julia

The first global agreement to reduce greenhouse gases, the Kyoto Protocol, was adopted in 1997.
