Green Party of New Brunswick Policy Proposal: Transportation
As of 2016, global carbon emissions have risen on the trajectory of the “business-as-usual” scenario RCP8.5 as described by the Intergovernmental Panel on Climate Change (IPCC) of the United Nations. If not mitigated, the growth in greenhouse gases (GHGs) will increase global average temperature up to 4.5oC over pre-Industrial Revolution times by the year 2100. The scientific community consensus is that this level of warming would lead to catastrophic levels of climatic disruption. In 2015 at COP21 in Paris, France, the world leaders reached an historic agreement to limit global warming to no more than 2o C and additionally try to limit warming to 1.5o C. Even 2o C of global warming is likely to cause significant ecological damage, and human hardship and misery,. In 2016, CarbonBrief estimated that only 20 years of carbon budget were left to have even a 66% chance of limiting warming to that level.
Global warming reached 1.1o C above pre-industrial times in 2016. At that level glaciers are melting, threatening global water supplies. Polar ice is receding at an alarming rate and what ice remains is spongy and vulnerable, so many climate scientists now expect Arctic ice to disappear many decades ahead of when they believed it would disappear just a few short years ago. Sea levels are rising, leading to evacuations of people from low-lying island nations and increasing the threats of storm damage due to tidal surges in coastal areas. Storm intensities with higher precipitation are increasing. Coral reefs are dying. Tropical storms are intensifying. The Amazon rain forest is drying out and becoming a tinderbox. Many areas are experiencing unprecedented heat waves and droughts. Conflict in places like Syria is exacerbated by climate-induced drought, and heralds the arrival of resource wars fuelled by the climate crisis.
