In a study published in <i><a href="http://link.springer.com/article/10.1007/s00382-020-05521-x">Climate Dynamics</a></i>, researchers from ƻ����Ժ introduce a new and more precise way to project the Earth’s temperature. Based on historical data, it considerably reduces uncertainties compared to previous approaches.</p> Mon, 21 Dec 2020 16:24:38 +0000 webfull 166429 at /channels /channels/channels/news/analyzing-extreme-weather-and-climate-new-statistical-tool-288997 <p>Due to processes occurring over vast ranges of scale, from fast to slow and from small to large, extreme weather and climate events aren’t as rare as scientists have thought – and that could complicate efforts to determine when extreme events signal perilous climate change, according to a new analysis published in the journal <em>Scientific Reports</em>.<br /><br /></p> Thu, 23 Aug 2018 15:03:26 +0000 webfull 140194 at /channels /channels/channels/news/new-approach-global-warming-projections-could-make-regional-estimates-more-precise-287175 <p>A new method for projecting how the temperature will respond to human impacts supports the outlook for substantial global warming throughout this century – but also indicates that, in many regions, warming patterns are likely to vary significantly from those estimated by widely used computer models.</p> Tue, 15 May 2018 15:11:53 +0000 webfull 137982 at /channels /channels/news/research-shows-global-warming-isn%E2%80%99t-natural-237013 Tue, 10 Jun 2014 14:47:23 +0000 webfull 103175 at /channels /channels/news/paris-climate-change-conference-nov-dec-2015-256412 <p><img src="//www.mcgill.ca/newsroom/files/newsroom/banner_paris_700x220.jpg" /></p> <p> </p> <p>The 2015 United Nations Climate Change Conference, COP 21, will be held in Paris from November 30 to December 11.
