The 27th U.N. Climate Change Conference (COP27) was held in Sharm el-Sheikh, Egypt, from Nov. 6 to 20. World leaders kickstarted the conference on an urgent and somber note. 2022 has shown that climate change can indeed pose an existential threat to humanity, as the year has been marked with several devastating and unprecedented floods, heat waves, droughts and storms. Making matters worse were the geopolitical tensions leading to crises in energy, food, water and inflation.
