Projected 2300 CE climates on a 6-7 C warmer future Earth

"a worldwide green energy transition, scaling up of carbon sequestration, and general worldwide economic collapse with some climate refugee migrations thrown in."

Sounds horrible. Not sure why anyone would want that.

Projection for Wuhan- this is around 8 C hotter than the 1981-2010 normals. Average temperatures are surprisingly similar to Riyadh (guess that was what I was going for when I made this climate). Rainfall is marginally higher, which given the much hotter temperatures means the overall climate is more arid (albeit still easily C_a in the Koppen and Trewartha systems).

Projection for Singapore- this is only ~3 C hotter than present-day (30.6 C vs 27.8 C per the 1991-2020 normals). Not sure why I made the precipitation pattern less seasonal/monsoon-dependent way back when than the current climate; maybe a drastically lower N-Hemisphere winter temperature gradient results in a weaker Northeast Monsoon?


The current normals, for context

Played around in Google Colab to produce daily averages for what this would look like

Dry bulb and [typo] dew point temps (Celsius)


Weatherspark-style 31-day rolling precipitation average (mm)

"To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year."

somewhat annoying in that it doesn't give you a climate chart of what these CE 2080 projections will look like. a surprising number of no-analog climates here

Thankfully, it's about as likely as me finding a suitcase containing Donald Trump's entire net worth on the sidewalk tomorrow.

The year is 2300 and it's July. Heathrow just had its cloudiest summer month on record with an average max of just 24c. Paris, Amsterdam, Umea, Turku have all had record hot summers to date with average maxs in the low 30s. Le Fuc now averages 40C and Niceeeee is basically Singapore in summer. Meanwhile Athens and Altea have burned to a crisp as the 60c summers coupled with 40c SSTs caused huge hurricanes that gobbled up all the houmus and rained down over the entire country, especially Crete where locals drowned in the burning hot mixture.

MA in NE USA is now unbearable in summer and a local resident by the name of cumbium got so unbearably hot that he drove north to Canada. Whilst driving his dashboard melted, spilling his dunkin donuts coffee over his legs, burning his small micro penis off in the process.

Due to to the warming world, the high pressure is now a semi permanent fixture in the Bight in SW Australia. Unfortunately the warming seas have affected ocean currents, resulting in a cooling trend in the southern ocean and a strengthening of southerlies hitting Victoria and SA. Melbourne, Renmark and the rest of Vic are the only places in the world along with the UK that have failed to see a single increase in temperature and are in fact cooling down. As the rest of the world heats up, many people have flocked to these coldspots in Melbourne, particularly from China to the delight of nearby previous resident Beercules. 'I fucken love it here now, I even moved back to Melbourne. These hot Asian chicks driving Toyotas around at 15kmh is the real shit' he was heard saying. Melbourne now no longer serves alcohol and steaks and KFC has closed down.

Meanwhile, Seattle now has a decent climate, but local resident botev is nowhere to be seen. It's claimed the sun shines so much on Seattle and the drastic change from a stratocrapulus filled cold and damp temperate rainforest to a Mediterranean paradise heated up his brain, expanding from the size of a pea back to normal size. Being used to cool oceanic weather he quickly decided it was time to move to London.

Projection for Shanghai- this is around 7-8 C hotter than the 1981-2010 and 1991-2020 normals. Winters are ~10 C warmer but summers are only ~4 C hotter and not that different from how Shanghai is averaging this summer during 2024 actually... Annual rainfall is maybe 25% higher than present-day Shanghai, but because this climate is typologically more "tropical", it also exhibits a more pronounced summer rainfall peak.
