Your arguments are as nonsensical now as they were 4 months ago
when you tried the same thing (well, you've modified the rate down to 2.3%
instead of 2.8%). You and Murphy do not understand very basic things
about scientific extrapolation and modeling.

Yes, if energy usage grows at 2.3%/year, after 400 years we'll be over
the boiling point of water. But it's equally true and informative
that if energy usage grows at 100%/year, after 15 years we'll be far above
the boiling point of water.  Ie, both have no relation to reality.

Modeling of the future is not done directly based on historical data;
it is done based on expected value in the future.  As you very well
know, having carefully read the evidence and citations I presented
4 months ago, the expected energy growth is far less than even 2.3%/year.
The US forecast I presented back then was for growth between 0 and 15%
total by year 2050.

So how about some current figures:
https://yearbook.enerdata.net/total-energy/world-consumption-statistics.html
From 2010 to 2019 growth rate was 1.5%/year worldwide.

In 2023 it was markably higher (2.2%) but that was pretty much due to
a big bump by China (6.6%).

The energy growth in the developed countries (OECD) was -1.5% in 2023.
Does that mean we have to worry about reaching the freezing point of
water instead? (Not a serious question).  As countries develop, their
growth rate will eventually decrease, given current concerns.

In any case, I know of no scientists predicting a growth rate of 2.3%/year.
Your model does not reflect reality and your comments are pointless.
