The Intergovernmental Panel on Climate Change issued a warning: if the world keeps going at present rate, we’ll miss the target agreed upon in Paris 2015 (COP21) for limiting global warming. The goal of 1.5 may be out of reach; 2.0 Celsius may be unlikely.
Human activities are estimated to have caused approximately 1.0 Centigrade of global warming, above pre-industrial levels, with a likely range of 0.8 to 1.2. Global warming is likely to reach 1.5 between 2030 and 2052 if it continues to increase at the current rate.
Consequences include extreme weather events, damage to warm water corals, mangroves, arctic, coastal flooding, fluvial flooding, terrestrial ecosystem, crop yields. (Reasons for Concern RFCs). The IPCC advocates climate-resilient development pathways (CRDPs) that “strengthen sustainable development at multiple scales and efforts to eradicate poverty through equitable societal system transitions and transformations while reducing the threat of climate change through ambitious mitigation, adaptation, and climate resilience.” (IPCC SR1.5)
