Those are some high falutin principles, ironically all about science.   There has been plenty of scientific understanding of the consequences of human actions that have led to anthropogenic climate disruption and the melting of the Arctic.   Frank Capra made a movie in the late 50s about CO2 as a greenhouse gas and its warming effects.   No one cared.   The fact that burning fossil fuels would warm the planet was known in the 1850s.   They thought it would be a good thing.   It was discussed in scientific and political circles in the 1890s, as well.  

Our point of no return occurred decades ago.  The extreme floods, fires and storms, the collapsing economy, the dying oceans, and the exploding number of people leaving drought stricken regions and other environmentally and war devastated parts of the world is the new normal.  It's not going away, but the future will be worse.
