Saturday marks two years since President Trump announced he would pull the U.S. out of the Paris Climate Agreement — and the chasm between scientific findings and political action is only growing.
The big picture: Climate science is now more clear than ever about the damage that climate change is causing. But many countries aren’t on track to meet their Paris emissions targets — and now there’s no U.S. leadership to push them to try harder.
The details: Scientists tell Axios they now have:
More confidence in the observed amounts of global warming, showing the planet has been heating up faster than previously thought, from the poles to the depths of the seas.Clear evidence that virtually all of the observed warming since 1950 is due to human activities. Robust data showing that limiting global warming to the Paris targets of 1.5°C or 2°C would have significant, tangible benefits by reducing damage.
Between the lines: A study published last week projected that unchecked growth in greenhouse gas emissions could cause global sea levels to rise by an average of 3.6 feet by 2100.
This compares to just 2.3 feet if warming is limited to 2°C above preindustrial levels, coauthor Robert Kopp tells Axios. The lower the
