"Without drastic action, our planet is headed toward warming of 3.2 C in less than 100 years, according to a new report.
The United Nations Environment Programme (UNEP) released its annual Emissions Gap Report on Tuesday — 168 pages, compiled by 57 leading scientists from 33 institutions across 25 countries — calling on governments to act immediately, within the next decade, to limit global warming to 1.5 C or 2 C by 2100.
"By now, we know all we need to know. The science is pretty clear, and very frightening," said Anne Olhoff, head of strategy, climate and planning and policy for the UNEP DTU (Technical University of Denmark) Partnership. "But we also know we have the technological options that are needed, at least to the short to medium term."
The report assesses scientific studies on both current greenhouse gas emissions and estimated future emissions, comparing them with possible reduction targets to avoid warming the world more than 1.5 to 2 C."
