@Ceist8 @BlogSlovenija @PeterDClack @Reality_vs_fic I understand but everything has tradeoffs. Just curious if you preferred one non-fossil fuel source over another. It looks like data center construction may incentivize more nuclear and solar. Anyways, thanks for your time.

[Drew Stearns @DrewStearns]

@Ceist8 @BlogSlovenija @PeterDClack @Reality_vs_fic So... nuclear? Solar? Is it too late to reverse the trend? Are there projections about how quickly we can turn it around?

[Drew Stearns @DrewStearns]

@Ceist8 @BlogSlovenija @PeterDClack @Reality_vs_fic Okay, I watched the video. Very compelling! At the end, Alley says humanity is now in position to build a sustainable energy system that powers us forever. I went on to read that he favors nuclear and other sustainable technologies. Any opinion potential solutions?

[Drew Stearns @DrewStearns]

@Ceist8 @BlogSlovenija @PeterDClack @Reality_vs_fic Thanks again!

[Drew Stearns @DrewStearns]

@Ceist8 @BlogSlovenija @PeterDClack Thanks and thanks @Reality_vs_fic. What about way further back? Is the cycle you described the "baseline"? Are there exogenous events that permanently alter the baseline or do we just veer off temporarily and "revert to the mean"? Deepest history I've seen is ~500ma?

@Ceist8 @BlogSlovenija @PeterDClack What caused the warming at 17K?

A farmer dies in April 2026.

His son inherits the farm. The farm has been in the family since 1847.

The farm consists of: 300 acres of grazing pasture, a farmhouse built in 1892, a barn, a milking parlour, two tractors of varying ages, a Land Rover that runs about 70% of the time, and a herd of 180 Hereford-cross cattle.

On paper, the farm is worth approximately £3.2 million. This is because land near him has been bought recently by a London hedge fund looking for carbon credits, which has dragged the comparable value of every field within forty miles upward to a number nobody local can justify.

In cash, the farm produces a profit of about £28,000 a year in a good year. In a bad year it loses money. The son also works as a fencing contractor three days a week to keep the operation viable.

The inheritance tax bill on a £3.2 million estate, even at the reduced 20% rate, comes to approximately £140,000 after the increased threshold is applied. The son does not have £140,000. The son has never had £140,000. The son has £4,200 in his current account and an overdraft.

The son sells 60 acres to a developer to pay the tax. The developer puts solar panels on the 60 acres. The remaining herd cannot be sustained on the reduced land. The herd is sold. The barn becomes a holiday let.

A different family eats Brazilian beef this Christmas without knowing why the price went up.

The Treasury collects £140,000.

The land never produces British food again.

HER: I have a boyfriend.
