SAN FRANCISCO — The northernmost mummified forest ever found in Canada is revealing how plants struggled to endure a long-ago global cooling.
Researchers believe the trees — buried by a landslide and exquisitely preserved 2 to 8 million years ago — will help them predict how today’s Arctic will respond to global warming.
They also suspect that many more mummified forests could emerge across North America as Arctic ice continues to melt. As the wood is exposed and begins to rot, it could release significant amounts of methane and carbon dioxide into the atmosphere — and actually boost global warming. (more…)
