President Donald Trump’s decision to withdraw the U.S. from the Paris climate agreement on Thursday could make it difficult, if not impossible, for the world to stay on track to reach an internationally agreed goal of limiting dangerous global warming, scientists said.
(The Washington Post, Chris Mooney) — That goal, which sought to limit warming to “well below” a 2 degree Celsius (3.6 degree Fahrenheit) rise above pre-industrial temperatures, was already a stretch, even before Trump announced the U.S. exit at the White House rose garden. Now with the U.S., the world’s second largest emitter of greenhouse gas emissions after China, walking away from the accord, other countries would presumably have to ramp up their ambitions still further if they want to avoid the prospect of dangerous warming.
“Climate change has far-reaching implications to everyone on our planet, as it is tied closely with national security, economics, human health, and food security. There is consensus in the scientific community – climate is changing. Now we need policymakers to act, to invest in research to understand the effects of climate change and opportunities to mitigate its drivers, and to adapt to its impacts.” — RADM Jonathan W.
