Can an Unequal Earth Beat Climate Change?
Some 250 million years ago, life on Earth survived an existential climate crisis. But that Earth had a distinct advantage. No rich.
We either keep fossil fuels in the ground, or all of us are going to fry. So essentially posits still another new blockbuster study on climate change, this one just published in the Proceedings of the National Academy of Sciences. Our fossil-fuel industrial economy, the study details, has made for the fastest climate changes our Earth has ever seen.
“If we think about the future in terms of the past, where we are going is uncharted territory for human society,” notes the study lead author Kevin Burke from the University of Wisconsin.
“In the roughly 20 to 25 years I have been working in the field,” adds another researcher on the effort, Wisconsin’s John Williams, “we have gone from expecting climate change to happen, to detecting the effects, and now, we are seeing that it’s causing harm,” as measured in property damage and deaths, in intensified flooding and fires.
The last time climate on Earth saw nearly as drastic and rapid a climate shift, scientists relate in another new study published in the journal Science, came some 252 million years ago, and that shift unfolded over the span of a few thousand years. That span of time saw the extinction of 96 percent of the Earth’s ocean species and almost as devastating a loss to terrestrial creatures.
Other scientific studies over this past year — most notably an October report from the Intergovernmental Panel on Climate Change that warned we have a dozen years to avert a climate catastrophe — have made similarly alarming observations and together provided an apt backdrop for this month’s United Nations climate change talks in Poland.
