Climate change and the SDGs. The science is clear: our climate is heating rapidly. The average global temperatures have increased by 1.2 degrees Celsius since 1880, particularly in the late 20th century. The concentration of atmospheric CO2, the GHG that contributes more than 2/3 to global warming, is at its highest level ever. The Intergovernmental Panel on Climate Change (IPCC) steadily points out that human activities have warmed the atmosphere, ocean and land, producing widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere. Due to these changes in climate, the number of weather, climate and water-related disasters has increased by a factor of five over the past 50 years, causing over 2 million deaths and US$3.64 trillion in losses.
