ENVIRON 157 Chapter Notes - Chapter N/A: Paul Nurse, World Economic Forum, Ocean Acidification
Document Summary
Pub pol 461 week 2 reading 1: the atmosphere and oceans have warmed, which has been accompanied by sea level rise, a strong decline in arctic sea ice, and other climate-related changes. The impacts of climate change on people and nature are increasingly apparent. Unprecedented flooding, heat waves, and wildfires have cost billions in damages. For example, the period of slower warming during the 2000s and early 2010s has ended with a dramatic jump to warmer temperatures between 2014 and 2015. Antarctic sea ice extent, which had been increasing, began to decline in 2014, reaching a record low in 2017 that has persisted. These and other recent observations have been woven into the discussions of the questions addressed in this booklet. The 2020 global risks perception survey from the world economic forum ranked climate change and related environmental issues as the top five global risks likely to occur within the next ten years.
