Through the 2015 Paris Agreement, world governments devoted to curbing worldwide temperature increase to well-below 2C above pre-industrial levels and pursuing efforts to limit warming to 1. 5C. In 2018, the Intergovernmental Panel on Climate Change warned that global warming needs to not go beyond 1. 5C to avoid the catastrophic effects of environment change. To accomplish this, GHG emissions should cut in half by 2030 and drop to net-zero by 2050. We have restricted time for action and the economic sector has an important function to play every sector in every market need to change. Companies with science-based targets are already cutting emissions at scale; all companies must now join them.
Pi is the ratio of a circle's circumference to its diameter. But some mathematicians say life would be much easier if we used a different ratio instead.
