Not to mention we have an extremely limited data set to work from when identifying what “normal” is.

We're not talking about vague shifting definitions of "normal." We're talking about "the wettest 12 months ever recorded," in the 125 years we have data for.

And you know there wasnt something wetter 150 years ago how?

Not really. The delta in how data is collected in August and December is much smaller than 1980 to 2020. So such determinations aren’t as straightforward as you imply. Not to mention none of the catastrophic climate consequences predicted in 1980 came to pass, but somehow we are supposed to be so much more certain about the prognosticators of today.

Which predicted catastrophes? The only one I remember is the ozone layer issue which we stopped with regulation and still pay the price (although it's getting better)

You ever see the movie Waterworld? Some people actually believe that to be a possibility.

Guess it is somehow not happening in UK though, weird! :-) https://www.metoffice.gov.uk/research/climate/maps-and-data/...

To be fair, the UK is not in the US, no matter how many high school students might guess that it is...

So US-only warming instead of global? Confused. Admittedly I may not understand, is US is expected to be impacted differently by global warming than other countries?

Global climate change => higher air temperatures => more water in the air => more water available to fall out of the air.

The most powerful supercomputers in the world are focused on weather analysis and they can only project a few days out. Yet, some people think they've got it figured out.

I can't predict the cards in my next hand of blackjack, but I'm sure if I play all night the house will win in the end.

I'd take some convincing that anyone actually thinks a terrible movie that had a thousand metres, or whatever it was, of sea level rise is a real possibility.

We're "only" looking at a rise under 100m even if we lose both ice caps. Which would take centuries to fully melt... Would still end up being catastrophic for the society we built.

The most powerful supercomputers in the world are not even close in processing power of a 4 year old. Isn't it possible that some people can see patterns that the supercomputers can't?

Sure, but those supercomputers aren't autonomous, they're programmed and designed by thousands of human adult experts.

"Thousands" is true, but, in the specific domain of modelling the climate there are not that many people doing it.

Weather forecasting is more about interpreting the results than writing the code for the model, and, realistically there are only the British and American weather supercomputers. Everyone else is borrowing the GRIB data and then doing their own interpretations.

As for that interpretation, a surprising amount of forecasters operate much like how gamblers work.

Think of a horse racing scene, the horses and the riders have form, i.e. how they have performed in the past. Then there is the course, this may or may not suit a given horse/rider combo. Weather, time of day and other factors come into it. Not to mention the prize money and the competition.

A gambler looks at the form, the weather and works with their niche of specialist knowledge, similar with weather forecasting.

The 'bet' might be what the weather is going to be in Dudley tomorrow or in Barnstaple, or anywhere else. The goal of the forecaster is to get it right. The observations are the key to it and the GRIB forecast data is not to be considered strictly accurate. Even if it is accurate it still needs interpretation. Even with the data and an eye on the metosat images it is incredibly hard to get the likelihood of rain right.

Sometimes a step outside is needed too - with a local forecast.

The resolution of the GRIB is not that good, so if you have a town at the foot of a mountain and next to a lake, it might not have a realistic prediction. The GRIB data might be for the top of the mountain or the middle of the lake. You need an expert to actually do an educated guess as to what temperature it will be there in the morning.

Forecasters actually understand some things that are going on in the now, so a storm off Africa that goes across to the U.S seaboard as some tropical storm will come back across to the British Isles as rain. Forecasters don't tell you that there is a queue of storms heading across the Atlantic on the way to the U.S. and inevitably going to bring rain to the UK after that. But that information could inform your holiday plans for a few weeks ahead. The computer and the meteosat images might show all this but they won't interpret it for you.

Then, when you get down to it, forecasting can often be done with horse betting mentality, like a gambling addiction.

What would be cool is to have a consumer grade version of the software the weather forecasters use, where you can go forward and back in time layering up different types of data at different altitudes. But weather forecasting is like its own magic circle and it would be betrayal of sorts to share the tricks and the props with the audience.

The landmass of North America will experience different effects of climate change than other landmasses. There might be similarities between it and other areas, like South America, but South America has a large cold continent to it's south while North America has a small cold ocean to it's north.

Dr. Heinrich Svensmark has physical experimental evidence that cosmic rays seed clouds.

The Earth's magnetosphere & Sun's Heliosphere are measurably weakened due to the Grand Solar Minimum. The Earth is also going through a magnetic pole reversal. These magnetic fields shield Earth from cosmic rays. If they are weaker, Earth will be bombarded by cosmic rays.

The other planets in the solar system are have observed effects of cosmic ray bombardment.

A model backed by physical experimental evidence & reliable observations is the basis of the scientific process.

And these people can make mistakes or be biased. If we can't predict what the weather in our hometowns will be how can we predict how will the climate change?

You can't predict where a bubble will form when boiling water, but you can predict that the pot will get to over 100C.

But doesn't that depend on how large is the pot and how much energy you're putting into boiling it? Not to mention that you also need to know the environment in the which you're trying to boil the water. If you're trying to boil the water in the middle of arctic winter, can you predict that the pot will get to over 100C if you're using just a small camping stove? :)
