Many people are aware that the Arctic is disproportionately impacted by Global Warming. I recently came across a web article titled “These infographics show how doomed the Arctic really is.” The graphs do convey in a powerful manner the rapidity with which climate change is transforming the region, particularly by melting the sea ice covering the Arctic Ocean. The particular danger is that there are positive feedback loops associated with climate change in the Arctic. When ice is replaced open water, it changes the albedo of the ocean surface, so that much more heat is absorbed. Significantly, when permafrost melts it releases significant amounts of methane. Accordingly, the Arctic not only witnesses temperatures that are rising much more quickly than at southerly latitudes, but also the region itself may particularly contribute to the planet’s temperature rise.
