Death of Planet Earth? –“The Sixth Great Extinction is Premature”

6th Mass Extinction

 

In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident with the widespread extermination of marine species around the world.

X Ray Sun

 

We didn’t know what the Sun looked like in its first billion years, and it’s super important because it likely changed how Venus’ atmosphere evolved and how quickly it lost water, said Prabal Saxena, an astrophysicist at NASA’s Goddard Space Flight Center. “It also probably changed how quickly Mars lost its atmosphere, and it changed the atmospheric chemistry of Earth.”
