How many of you think scientists can measure the changes in earth's temperature over the past 125,000 years?
@VoterIDPuddingGreen5mos5MO
It's been measured accurately for the past few decades and the global mean has definitely risen. You're correct that there are many assumptions made when going further back than that.
@LynxLeoRepublican5mos5MO
Absurd. There is no way to do it.
@SimilarP0pulistLibertarian5mos5MO
You are correct, it is modeling.
I would go one further and point out that temperature measurement has been getting less accurate over the last 40 years...
Urban island effect is mostly what is being observed. So if we don't have the last 100 years correct, 125K?

Actually geologist can tell the sea levels were much higher during the last interglacial period. Which indicates it was warmer.
@Patriot-#1776Constitution5mos5MO
Here's a basic fact for you – water, when it is frozen into ice, EXPANDS. Ice, when it melts, DETRACTS. ICE TAKES UP MORE SPACE THAN LIQUID. Try it at home, freeze a half-filled cup of water and see if it expands, I can guarantee it will, and then watch it detract as it melts. Therefore, if the world was truly getting warmer and the ice caps were melting, the sea level would be GOING DOWN rather than up.

Yes, but the issue with this EXTREMELY common argument is that one does not account for the increased or decreased salinity of the water.
@Patriot-#1776Constitution5mos5MO
Does it need to? As far as I was concerned, we were talking about rising sea levels, not the specific properties of water! And the salinity, unlike the sea level, is not a metric that can rise or fall all over the world at once, it's a very area-specific thing that is vastly different in different parts of the world.
