Problem is that the IPCC says it has low confidence that there is any connection between global warming and any change in hurricanes, and as I've posted many times, there's no trend in the graphs.
This makes sense, since it is temperature differential that primarily drives hurricane formation and strengthening, not overall increases in temperature.
 
The proliferation new descriptions has not helped: 'bomb cyclone' for a storm that has a rapid drop in barometric pressure has a better sound for news stories and every news outlet is hungering to get eyes so the copy is pumped with superlatives and 'unprecedented this' or 'unprecedented that' . . . When many coastal/watershed areas were unpopulated or considered waste land swamps there probably 'unprecedented' intensity storms that just did not have a significant impact on humans. I cannot stand watching the Weather Channel type broadcasts. They hype the coverage to a sporting event/paegent fever. Storms are natural events and are only human diasters.
 
The problem is that temperature does not represent the quantity of energy. If a climatologist ever makes the enthalpy connection I'll buy into their movement. At STP there is nearly 4x difference in energy between 0% humidity and 100%.
 
A heat engine must be driven by the delta between hot and cold reservoirs. Since the Arctic has been warming more than the tropics it seems unlikely that at least at a hemispherical level there is more energy going into the atmosphere.
 
This could get interesting...

"The case put before the International Court of Justice will be the largest in its history and is likely to help vulnerable nations fight the devastating impact of global warming.

After years of lobbying by island nations who fear they could simply disappear under rising sea waters, the U.N. General Assembly asked the International Court of Justice last year for an opinion on “the obligations of States in respect of climate change.”

“We want the court to confirm that the conduct that has wrecked the climate is unlawful,” Margaretha Wewerinke-Singh, who is leading the legal team for the Pacific island nation of Vanuatu, told The Associated Press.

In the decade up to 2023, sea levels have risen by a global average of around 4.3 centimetres, with parts of the Pacific rising higher still. The world has also warmed 1.3 degrees Celsius since pre-industrial times because of the burning of fossil fuels."

 
Since the Arctic has been warming more than the tropics it seems unlikely that at least at a hemispherical level there is more energy going into the atmosphere.
This can change circulation patterns (ocean and atmosphere) with even more interesting effects.
 
Talking of islands vanishing under the sea, surveys find that the atolls are in general growing not sinking. But you knew that, you just declined to mention it. The Maldives are building 7 new runways.
