2. History of climate change

‘History of climate change’ traces the history of climate change and the evidence that supports it. The science of climate change started in 1856 with experiments by Eunice Newton Foote demonstrating the greenhouse effect of carbon dioxide. The essential science of climate change was there in the late 1950s, but it was not taken seriously until the late 1980s. Why was there a delay between the science of global warming being accepted in the late 1950s and the realization by those outside the scientific community of the true threat of global warming at the beginning of the 21st century? The key reasons for this delay were the lack of increase in global temperatures and the lack of global environmental awareness. What is the importance of the rise of the global environmental social movement and the new wave of protest and optimism of the last few years?
