The amount of carbon dioxide released into the atmosphere from these volcanic eruptions is comparable to the amount of CO<sub>2</sub> expected to be produced by all human activity in the 21st century.</p> Tue, 14 Apr 2020 14:54:46 +0000 shirley.cardenas@mcgill.ca 208241 at /newsroom /newsroom/channels/news/mcgill-expert-record-high-greenhouse-gases-238773 Tue, 09 Sep 2014 15:30:30 +0000 raphael.larocque-cyr@mcgill.ca 21110 at /newsroom /newsroom/channels/news/global-warming-pause-reflects-natural-fluctuation-237538 <p>Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by ºÚÁϲ»´òìÈ physics professor Shaun Lovejoy.</p> <p> Mon, 21 Jul 2014 18:06:18 +0000 christopher.chipello@mcgill.ca 20975 at /newsroom
