Short summary
During the globally warm early Eocene 56 million years ago, lush forests extended up to the high Arctic. Fossil plants from the Canadian High Arctic and Pacific Northwest of North America are a window into this past greenhouse world. We used an improved method for plant fossil climate reconstruction that provides a consensus reconstruction from all available proxies. Results show that the early Eocene climate in northern North America was similar across a broad range of latitudes.
