"If there was any thread of hope for skeptics that global warming could be controlled by merely incremental changes to industrial processes and our way of life, the United Nation’s blue-ribbon Intergovernmental Panel on Climate Change dashed that permanently in August.

As U.N. Secretary-General António Guterres said in releasing the group's report, it was “a code red for humanity. The alarm bells are deafening, and the evidence is irrefutable.”

We are at imminent risk of hitting 1.5 degrees in the near term. The only way to prevent exceeding this threshold, is by urgently stepping up our efforts, and pursuing the most ambitious path.”"
