Some climatologists predict a new ice age. =>Venus & Mars, 1960 Meanwhile, the US government says it will not ratify the agreement unless it sees evidence of “meaningful participation” in reducing emissions from developing countries. 2002: Parliaments in the European Union, Japan and others ratify Kyoto. on emission of ozone-destroying gases. to gather data for better short-range weather prediction, but including Launch of Soviet Sputnik satellite. In December, Kyoto signatories agree to discuss emissions targets for the second compliance period beyond 2012, while countries without targets, including the US and China, agree to a “non-binding dialogue” on their future roles in curbing emissions. =>International. Industrialised nations agree on the need to negotiate real cuts in their emissions, to be concluded by the end of 1997. 1940 to 1970: Worldwide cooling of 0.2°C. 1996: At the second meeting of the Climate Change Convention, the US agrees for the first time to legally binding emissions targets and sides with the IPCC against influential sceptical scientists. doubling CO2 will bring 1.5-4.5°C global warming. feedbacks.
