The trend is becoming so pronounced, the researchers estimate, that it could start to cause serious health issues within just 50 years.
Given that humans have spent the majority of our evolutionary lifespan with a “usually stable level of atmospheric CO2,” the recent rise in airborn carbon pollution has forced our bones to compensate. As the researchers blunty explain: “human physiology has progressively and consistently altered over the last ~25 years.”
This is why I think the folks who think humanity is going to survive Climate Change are way too optimistic. On top of everything else, they’re turning our air into poison. At a certain point we’re just not gonna be able to breath.
Who are these people you speak of? I know of three basic climate change opinion groups.
There are soooo many people on this website who would be happy to tell you that while climate change may be bad, humans will survive it.
