Climate change is a topic that the United Nations has taken seriously for decades, having founded the United Nations Framework Convention on Climate Change (UNFCCC) already in 1994, initiated during the Rio de Janeiro Earth Summit in 1992. The Intergovernmental Panel on Climate Change has existed since 1988. They work “to provide policymakers with regular scientific assessments concerning climate change, its implications and potential future risks, as well as to put forward adaptation and mitigation strategies” (https://www.ipcc.ch/pdf/session48/pr_181008_P48_spm_en.pdf).
In December, the IPCC will present to the Katowice Climate Change Conference a Special Report on the effects of a global warming of 1.5⁰C above pre-industrial levels. Read the press release from the IPCC in the link above and make a note of what it says about the difference between a 1- and 2-degree increase compared to pre-industrial levels. Draw upon studies from your other subjects as well and be prepared to discuss the topic in class.
