Fun fact: During the Jurassic period CO2 levels were 4 to 5 times higher than now.
But I guess that won't be a problem if your apartment is above the 30th floor.
It's not relevant to the sharp increase in CO2 concentrations we've seen in the past century.
I saw on Google that it gets 6% brighter every 1 Billion years. That's a really long time, and I'm not sure what that even means anyway.
For our current situation, it means nothing.
The grandparent comment was referring to a period 100s of millions of years ago. Given that the sun's intensity has changed significantly on that scale, it's not appropriate to compare our current situation to that of something that happened 100s of millions of years ago.
For what it's worth, the atmospheric CO2 reduction that followed that period was associated with significant cooling and glaciation, which is further evidence that CO2 is a significant factor in determining global climate change. The grandparent comment was very disingenuous.
And in their minds, if they are smart, they will realize that their resale value will be based on the sea level 25 years from their unknown future resale date.
Now does that mean all buyers are factoring it in? Of course not. People are not used to long term thinking. And there are plenty of people who are in denial, and those people will make fine buyers for the short term. But at some point it’s likely the music will stop.
I made a slight edit of the original comment to clarify the point.
Price increase slopes can also change. The price can be going up, yet still be held back by something when it could have gone up even more.
