Ramanathan and collaborators announce that global warming may come is now decreasing. point out the chaotic nature of the climate system and the possibility of damage they will cause. This provides scientific clout for UN negotiations for a climate convention. 1945 will have a significant effect on the radiation balance. would raise sea levels catastrophically. Averyt, M. Tignor and H.L. =>International. =>Aerosols, 2003 Solar electricity and wind power become economically competitive with fossil fuels in some regions. =>Other gases, Eddy shows that there were prolonged periods without sunspots in past "2100 isn't enough. not included above in the list of major "milestones," Paris Agreement: nearly all nations pledge to set their own targets for greenhouse gas cuts and to report their progress. For at least 124 years, climate “scientists” have been claiming that the climate was going to kill us…but they have kept switching whether it was a coming ice age, or global warming. The nature of the evidence for climate change is explained, as are the principal mechanisms that have caused climate change throughout the history of Earth. Many experts warn that damage from climate change is arriving at a faster pace than was anticipated just a few years earlier. 2003-2020 Spencer Weart & American Institute of Physics, Introduction: likely. UNEP organized an internal seminar in January to identify environmental sectors that might be sensitive to climate change. =>Government, Speculation over catastrophic climate change following a nuclear war, or a dinosaur-killing asteroid strike, promote realization of the atmosphere's fragility. Measurements of solar activity show that it has declined since the 1980s, debunking the claim that it is responsible for global warming. =>Simple models, Plass calculates that adding CO2 to the atmosphere 2008: The polar bear is listed on the US endangered species act, because of the risk to its habitat from climate change. 1995) computer models of aerosol effects. agreements to restrict emissions.=> International, Antarctic ice cores show that CO2 and temperature This study shows how much more there is to learn about climate change and its effect that will still merely be bubbling under the surface by 2100. Research on small-scale phenomena in various fields of geophysics (cloud =>Other gases, 1879 is 315 ppm. =>Chaos theory, 1966 actual current warming in polar regions begin affecting public opinion. to small perturbations. claims they counteract global warming and may bring serious cooling. Both scientists realise that the burning of fossil fuels could lead to global warming, but neither suspects the process might already have begun. =>Public opinion, 1978 Here are gathered in chronological sequence the most important events in 2001: The new US president, George W Bush, renounces the Kyoto Protocol because he believes it will damage the US economy. from solar influences. arose altogether independently of the scientific fields covered, and are Advanced economies are increasingly 1985: First major international conference on the greenhouse effect at Villach, Austria, warns that greenhouse gases will “in the first half of the next century, cause a rise of global mean temperature which is greater than any in man’s history.” This could cause sea levels to rise by up to one metre, researchers say. The yellow-to-red regions indicate higher concentrations of CO2, while blue-to-green areas indicate lower concentrations, measured in parts per million. Coal, railroads, and land clearing speed 1963 went up and down together through past ice ages, pointing to powerful Home, copyright© =>Public opinion, Copenhagen conference fails to negotiate binding agreements: end of hopes of avoiding dangerous future climate change. Fourth IPCC report warns that serious effects of warming have Following is a timeline ahead of the November 29-December 10 meeting of the United Nations Framework Convention on Climate Change (UNFCCC) in Cancun, Mexico. =>International, Manabe and Wetherald make a convincing calculation Fourier calculates that the Earth would be far colder if it lacked could be a variable star =>Solar variation — =>Modern temp's, 2015 Fossil-fuel and other U.S. industries form Global Climate Coalition SMIC conference of leading scientists reports a danger of rapid and serious Election of Reagan brings backlash against environmental hybrid car; swift progress in large wind turbines, solar electricity, and other energy alternatives. =>Government, 1955 =>Models (GCMs), 2002 science, some of which happen to be useful for understanding climate change. Climate scientists (although not the public) recognize that even if all greenhouse gas emissions could be halted immediately, global warming will continue for millennia.
