In honour of the weirdo, banned, dancing creep Jackierudetsky I start this one for what actually is an interesting hypothetic scenario. Let's say the rotation of the earth flipped so that west coasts and east coasts flipped but everything stayed in the absolute same spot. Now that he's banned, we can avoid questions about these subjects and actually propose real interesting scenarios. Personally I believe NYC would be much more like Portugal in that scenario rather than being a say San Francisco. The Gulf Stream water would probably transfer over to the now blush, tropical latitudes outside of Morocco/Mauritania and start pumping the US east coast with warm water. In front of the Appalachian mountains there would be some kind of maritime wall though, so I'd expect NYC of today to very much influence Porto in that scenario. Europe would be a freezing tundra up where I live and a Dfb/Dfc hybrid on the continent. The Med would regularly freeze in say the Adriatic Sea during winter, causing severe winters as far south as in Rome due to the monster cold waves built up over the Ural Mountain area. Porto would have some similarities to Boston, since the Iberian landmass in summer would propel temps up high. Most of Europe's population would live around the snowy, quasi Dfb/Dfa climates around the Med and European civilization would dominate North Africa due to their superior warcraft during the late Middle Ages. California would see some very interesting maritime microclimates on its coast in front of the mountains, although nowhere near as spectacular as today. Even Sunset District in San Francisco would average around 30C in summer with scorching summer nights and the Bay being one of the top charter destinations for swimming around. North of that, Eureka would probably have 25-26C July highs right by the water, with the interior behind it being more like Chicago. I assume many of us would be far colder with this scenario, and probably where humans would've lived would've changed a crazy lot. It's entirely possible that the Kamchatka Peninsula would be like the Northern France/England of that world for example  What do you lot think? |

This is my climate in that scenario   |

Yeah, NYC would likely have a low end Csa, or borderline Csb climate, something in between Lisbon and Porto, but with a massive UHI.
Without the Gulf Stream, NYC might have the same climate as Eureka, CA and I’d projectile vomit. But I could see it being a bit warmer than Eureka (but with cooler winters) due to the curvature of the NE USA/CAN coastline compared to the mostly vertical coastline of Northern California through British Columbia. There’d be more land to the northwest, increasing the potential for continental influence.

Korean peninsula and Japan would have amazing climates in this case. Australia would be the same just flip Perff and Sydney's climates. Southern China would turn into a giant desert?
Chile would probably become warmer since its weather would now come from the landmass as opposed to the ultracold Pacific. Argentina would probably stay the same just become a bit more stable

UK would be like Siberia , and most likely uninhabitable.

UK would be like Siberia , and most likely uninhabitable. Nah more like the Sakhalin Island if you're familiar? This is Yuzhno-Sakhalinsk at 46N down its deep south. I'd guess this is quite similar to what Exeter would be like, given that the Med Sea would provide some mild air during winters and the Baltic Sea would take the worst hits of cold:  |

If that was Exeter, god forbid what Buxton and the north would be like. With those well below freezing winters we'd need all old houses replaced with much more efficient easy to heat buildings. So many in this country are designed such that they would be ideal in the tropics.

So many in this country are designed such that they would be ideal in the tropics. For Buxton, make that current Buxton summers with -13/-20 January's. Not fun. I'd guess the subarctic line would fall potentially as north as Birmingham though, given it's reasonable elevation that would make Septembers stick above 10C. But after that, no way. |

climate scientists have done computer simulations of this: www.climate-lab-book.ac.uk/2011/earth-backwards/I'm rather surprised; I thought the east coast of the US would warm, west coast would cool. for US East Coast: Perhaps the gulf stream shutdown cancels out the warming from ending most of the cold continental flow. Seasonal temperature range and precipitation would be very different of course. for US West Coast: The cold Pacific waters currently keeping the west coast cool but the average temperatures are fairly warm for its latitude. But the colder continental flow [flow over Cascades & Sierra would create a warm foehn effect blocking the coldest air so won't be that cold] must not matter much since the Pacific is currently so cold, so oceanic flow doesn't warm much when the wind direction switches [does it exactly switch?]. Upwelling of cold water should stop if the earth's rotation switch, so coastal waters would get much warmer outside of winter. East Asia warms a lot; unsurprisingly, it has the coldest winters for its latitude in the world currently so it has the most potential to warm, but does it still have monsoonal flow from the Pacific? Its mainly driven by a Thermal Low on the continent, which should be there regardless of circulation, but the wind direction would still be altered. I'd need to think about this more. The continent highs & low vs ocean would still be somewhat similar to today because continents warm & cool faster but the wind flow around pressure systems would be reverse of today. Would this mean northeasterlies from a Bermuda High? Gulf stream shutdown + prevailing easterlies from the Eurasian continent rather than Atlantic drastically cools northwest Europe of course. Another interesting find, though of course it's just a model: North African rainfall went up, and the Mediterranean received so much river input it became almost fresh. The reorganisation of the world’s hydrological cycle that we initiated might have frozen EuropeNorwegian mountains would probably get an ice cap; dunno how big it would be |

Auckland would literally remain almost entirely the same

NYC will have a far superior climate.

Northeast US would probably have lamer summers especially with a cold current running up the coast. Long Island might be similar to Eureka. Altho once you go 50 miles inland you'd get some epic summers probably, and with milder winters too

I imagine temperatures would be similar, but there would be a mediterranean rainfall pattern.   |

Most of the Southern Hemisphere would remain the same, just the precipitation pattern would flip. I wonder how South America and the Amazon would be impacted tho. South America has so many climate factors in play including the cold currents on both coasts, that it's the complete opposite of anywhere else in the world

I imagine temperatures would be similar, but there would be a mediterranean rainfall pattern. Why so sunny? Look at Albany, WA and Melbourne is even further south. |

The geographical features are still the same, so apart from maybe making the winters cloudier I'd keep the averages the same. Tasmania is still in the way there, and with that reversed current you'd probably see some Albany-like climates there. |

South FL would still be a shit climate.

Magadan would probably be a place many Siberians spent their summer holiday.
Norway would be like Baffin Island is today and most of us would freeze to death within a year
