’There is no global warming’: Senator Malcolm Roberts

One Nation Senator Malcolm Roberts has emphatically argued “there’s no warming” of the earth. Speaking to Sky News on Friday, Mr Roberts said “in Australia, the temperatures in the 1880s and 1890s were not only warmer than they are today, the heatwaves were longer”. Mr Roberts said the Bureau of Meteorology “has never proven that carbon dioxide from human activity affects temperatures” and urged anyone with proof to convince him otherwise.
