Fun fact: During the Jurassic period CO2 levels were 4 to 5 times higher than now.

Fun Fact, Sea Levels were on average 330 feet higher (110 meters) than they are now by the end of the Jurassic period. But I guess that won't be a problem if your apartment is above the 30th floor.

Okay, and what was the global GDP at the time?

Related fun fact: The sun was also 4-5% dimmer during this period. It's not relevant to the sharp increase in CO2 concentrations we've seen in the past century.

  Is the Sun only getting brighter, and if so, is it changing at a pace that would even have a noticeable impact in, say, 1000 years? 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.

    > 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.

Interesting. And what was the climate like?

Related fun fact: If you buy a house near sea level now, the resale value [edit: for buyers in the know] will not be based on the current sea level, it will be based on the projected sea level 25 years from now when the potential next buyers will still be paying their mortgage. 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.

  Pretty sure you made this up , or read it as posted by someone else who made it up. My home is in a waterfront community. Homes on the water are increasing in price.

    I am and have been a prospective buyer and have been basing shopping decisions on this already. So based on first hand information I have an existence proof that such buyers are out there already who are factoring this in today. And for the past 20 years in fact… when we bought our previous house we passed on certain locations based on this issue alone. 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.

    And loans are still being underwritten for beachfront property.
