Yale Environment360: More good long form on line journalism – this time, about tundra’s fade, boreal forest’s advance
The environment360 site, maintained by Yale University’s School of Forestry & Environmental Studies and an outlet for magazine-length, on line journalism, has a reader this week. Alaska writer Bill Sherwonit has a relaxed and deep look at how rising temperatures of recent decades are, sources tell him, spelling an end to much of the tundra landscape of Alaska. Presumably this goes for Canada and Eurasia’s northern latitudes too. Its drying is already spawning an upsurge in wildfire. Brush and trees are moving in as permafrost and the tundra’s mossy plants and lichen retreat. This could help explain, it says here, recent die-offs of a good share of the region’s caribou.
