This month's hard-hitting report from the U.N. climate science panel sounded the alarm on the surging impacts of global warming — but its authors and independent researchers said it did not provide enough insight on threats in poorer parts of the world.

Despite progress in recent years, the Intergovernmental Panel on Climate Change (IPCC) still relies primarily on lead authors and research from Europe, North America and Oceania, making its findings less relevant to developing nations.

"It is by far the biggest and the best collaborative global scientific enterprise that mankind has done — but it still has certain blind spots," said Saleemul Huq, head of the Bangladesh-based International Center for Climate Change and Development.
