Scientists who probed two kilometers (1.2 miles) through a Greenland glacier to recover the oldest plant DNA on record said Thursday the planet was far warmer hundreds of thousands of years ago than is generally believed. DNA of trees, plants and insects including butterflies and spiders from beneath the southern Greenland glacier was estimated to date to 450,000 to 900,000 years ago, according to the remnants retrieved from this long-vanished boreal forest. Yeah, and what happened to those trees, plants, butterflies, and spiders? They are all dead now, killed off by global climate change. The planet was far warmer then, and they died. We're doomed.
what happened to those trees, plants, butterflies, and spiders? It's called you get old and die. ;)
