This year, however, scientists found that 2\u00b0C was absolutely not enough, and a target of 1.5\u00b0C should be settled.<\/p>\n<p>According to the <a href=\"https:\/\/report.ipcc.ch\/sr15\/\">&#8220;New Climate Report&#8221;<\/a> which was released on October 7th by the Intergovernmental Panel on Climate Change (IPPC), a decrease from 2 degrees to 1.5 degrees Celsius changes the world to a great extent. If the goal is achieved by 2100, there will be a significant decrease in heat, drought and sea level rise. Hopefully, there will be fewer loss of species. There are two reasons why scientists published this report: Warning policymakers and calling for a lower warming target.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: left\"><strong>Why is it important?<\/strong><\/p>\n<p><iframe loading=\"lazy\" title=\"See the Effects of Climate Change Across Earth\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/uo80xYqZBiw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><em><strong>Video 2<\/strong><\/em>: <em>Effects of Climate Change Across the Earth<\/em><br \/>\n<em><strong>Video Credit<\/strong>: VideoFromSpace Youtube Channel <a href=\"https:\/\/youtu.be\/uo80xYqZBiw\">https:\/\/youtu.be\/uo80xYqZBiw<\/a><\/em><\/p>\n<p>The failure of achieving the goal suggested in the &#8220;New Climate Report&#8221; will affect our daily life. The knotty problem we are facing right now is the increasing number of disasters brought by extreme weather. For example, in February 2018, Vancouver experienced severe snowstorms which caused paralyzed traffic and huge economic loss of the city. These snowstorms occurred due to the La Nina Effect \u00ad\u2013 The melting sea ice in the Arctic brought icy waters into the Pacific Ocean and forced the coastal areas to have colder winters than they were before. This also increases the overall sea level and is threatening the existence of island countries such as the Republic of Maldives. In addition, stronger and more intense hurricanes have been attacking the US in recent years. What will be worse, however, is that such climate changes will continue and the weather will become more and more extreme.<\/p>\n<p><a href=\"https:\/\/interactive.carbonbrief.org\/impacts-climate-change-one-point-five-degrees-two-degrees\/?utm_source=web&amp;utm_campaign=Redirect#\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-571 size-medium\" src=\"https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57-300x262.png\" alt=\"\" width=\"300\" height=\"262\" srcset=\"https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57-300x262.png 300w, https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57-768x672.png 768w, https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57-1024x896.png 1024w, https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57-800x700.png 800w, https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.57.png 1164w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><em><strong>Figure<\/strong> <strong>1<\/strong>:\u00a0Effect of global warming on overall temperature: 1.5\u00b0C Versus 2\u00b0C<\/em><br \/>\n<em><strong>Source<\/strong>:<a href=\"http:\/\/interactive.carbonbrief.org\/impacts-climate-change-one-point-five-degrees-two-degrees\/?utm_source=web&amp;amp;utm_campaign=Redirect#\">\u00a0Carbon Brief\u00a0<\/a>\u00a0<\/em><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-572 size-medium\" src=\"https:\/\/blogs.ubc.ca\/communicatingscience2018w109\/files\/2018\/10\/Screen-Shot-2018-10-08-at-01.03.21-300x228.png\" alt=\"\" width=\"300\" height=\"228\" \/><\/p>\n<p><em><strong>Figure 2<\/strong>:\u00a0Effect of global warming on drought: 1.5\u00b0C Versus 2\u00b0C<\/em><br \/>\n<em><strong>Source<\/strong>: <a href=\"https:\/\/interactive.carbonbrief.org\/impacts-climate-change-one-point-five-degrees-two-degrees\/?utm_source=web&amp;utm_campaign=Redirect#\">Carbon Brief<\/a>\u00a0<\/em><\/p>\n<p>&nbsp;<\/p>\n<p><strong>How do we achieve the goal and what are the difficulties?<\/strong><strong>\u00a0<\/strong><\/p>\n<p>It will take approximately 30 years to reduce the emissions of greenhouse gases to zero and reach a balance (between emissions and reductions).
