Abstract
Many countries pledged to take necessary measures and limit the global temperature rise to 2 °C, or better yet, 1.5 °C, at the United Nations (UN) climate summit in Paris. However, according to a survey from <i>Nature</i>, many scientists think global temperatures may reach a disastrous 3 °C above preindustrial levels, and around 60% of experts from the Intergovernmental Panel on Climate Change (IPCC) expect average global temperatures to reach that point by the end of the century if governments do not markedly slow the pace of global warming <xref ref-type="bibr" rid="ref1">[1]</xref>. That dynamic played out again during the 26th UN Climate Change Conference (COP26), in Glasgow, United Kingdom, in November 2021. The prime minister of Barbados, Mia Mottley, declared that 2 °C of temperature rise would be a “death sentence” for island countries. On 13 November 2021, COP26 concluded with nearly 200 countries agreeing to the Glasgow Climate Pact, which aims to limit the global temperature rise to 1.5 °C and finalize the outstanding elements of the Paris Agreement.
