Now scientists from Â鶹AV have developed a gentler, more precise technique using low-power visible light.</p> Thu, 30 Jun 2022 17:13:10 +0000 shirley.cardenas@mcgill.ca 288232 at /newsroom /newsroom/channels/news/climate-change-threshold-dangerous-warming-will-likely-be-crossed-between-2027-2042-327290 <p>The threshold for dangerous global warming will likely be crossed between 2027 and 2042 – a much narrower window than the Intergovernmental Panel on Climate Change’s estimate of between now and 2052. 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 Â鶹AV 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 15:53:21 +0000 shirley.cardenas@mcgill.ca 254107 at /newsroom /newsroom/shaun-lovejoy Tue, 22 Dec 2020 16:47:05 +0000 shirley.cardenas@mcgill.ca 254223 at /newsroom /newsroom/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 13:58:54 +0000 laurie.devine@mcgill.ca 76729 at /newsroom /newsroom/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 15:01:54 +0000 justin.dupuis@mcgill.ca 40248 at /newsroom /newsroom/channels/news/paris-climate-change-conference-november-2015-256412 <p><img src="/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.

The celebrated “butterfly effect” also means that the reliability of weather forecasts drops sharply beyond 10 days.</span></p> <p> Tue, 18 Aug 2015 18:46:07 +0000 melody.enguix@mcgill.ca 24417 at /newsroom
