Rising carbon dioxide in the atmosphere may be leaving a measurable imprint inside the human body. Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels have climbed about 7% since 1999, while calcium and phosphorus have declined—changes that closely track increasing atmospheric CO2.
No, I mean 2050 is when we start to see linkable deaths. We don’t have time, that’s the point.
But that’s not what the article you linked said, so where are you getting 2050 from? The study says if CO2 continues to increase at the same current rate, we would be at the top end of the healthy max bicarbonate level by 2076. Do you have extra info that connects what is said in the article to 2050?
This 2024 study cuts off the trendline data in 2019. They give the annual rate of increase in CO2 concentration at “over 2ppm” which was the observed rate at that time.
However the rate surged, and in 2024 it was + 3.75ppm, almost doubling the speed of increase from those predictions. This is what the OP comment means by “at current rates”, the paper is way off from how fast things are moving now. We will get higher CO2 much sooner than what they predicted.
The paper basically just says there is an almost linear relationship between atmosphere and blood chemistry, so if we get higher CO2 faster, the health effects will track that.
So instead of 50 years until health effects, think ~ 30 years from now.
That’s the top end, you have to look at the bottom-end to understand the impacts to those marginalized populations - youths and seniors.
