- There has been a significant increase in global temperatures in that time (~0.5°C, which considering the limit from Paris is 1.5°C). Because human activity rise in urban areas, temperatures from rulal areas have not increased that much. Satellite and balloon measures proofs that. (1) Also rising temperatures is not new phenomena. Greenland ice core project (2) showing that there was about 25 dramatic climate changes in history. Its called Dansgaard–Oeschger event. (3), (4) and shows that for example during Younger Dryas (5) there was dramatic temperature decline and increase in few decades. Back to topic.
