The global community expects this type of authoritative scientific assessment on global existential threats from its international bodies; an example is the Intergovernmental Panel on Climate Change (IPCC) that was created to provide governments and the public with regular scientific assessments on climate change, risks posed, and solutions.

What the bill would do In 2019, Maine passed several major climate and clean energy bills, including increasing its renewable portfolio standard (RPS) to 80% by 2030 and adopting a non-binding goal of 100% renewable electricity by 2050. The current bill would further increase the RPS targets to 90% by 2040.
