Experts have since pointed out that the greenhouse analogy was an oversimplification, since outgoing infrared radiation isn’t exactly trapped by Earth’s atmosphere but absorbed. As global warming gained currency as a real phenomenon, researchers dug into possible ramifications of a warming climate. Many experts considered 2 degrees C of warming to be a critical limit, which, if surpassed will lead to increasing risk of more deadly heat waves, droughts, storms and rising global sea levels. Climate change . The Printing Press Prior to the rise of the Internet, no innovation did more for the spread and democratization of knowledge than Johannes Gutenberg’s printing press. As Arrehenius wrote, “By the influence of the increasing percentage of carbonic acid [CO2] in the atmosphere, we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth.”. Dating back to the ancient Greeks, many people had proposed that humans could change temperatures and influence rainfall by chopping down trees, plowing fields or irrigating a desert. Tab 1:Canada’s Nature Legacy: protecting our … Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space.Many of these gases occur naturally, but human activity is increasing the concentrations of some of them in the atmosphere, in particular: 1. carbon dioxide (CO2) 2. methane 3. nitrous oxide 4. fluorinated gasesCO2 is the greenhouse gas most commonly produced by human activities and it is responsible for 64% of man-made global warming. Scripps geochemist Charles Keeling was instrumental in outlining a way to record CO2 levels and in securing funding for the observatory, which was positioned in the center of the Pacific Ocean.
