Wall Street Journal op-ed by Steven Koonin publishes misleading claims about how climate change influences Greenland ice melt

Human-caused climate change is already accelerating Greenland’s melting and is predicted to continue to accelerate it in the future. In addition to Greenland, most glaciers around the planet are also melting at an accelerating pace. This melt, in addition to the expansion of the ocean as it warms, contributes to elevate sea level at an accelerating rate, threatening coastal cities around the globe.
