If the Americas were shifted 20 degrees south. (climate, snow, hottest)

[Mr.Sir]

I was just wondering how the climates of the Americas (both) would be if they shifted 20 degrees further south. It would be interesting with all of the continental U.S. below the 30th parallel, and tropical Brazil suddenly ranging from 15*S to 53*S. I know that South America would crash in to Antarctica, but for the purposes of the thread, let's assume that any part of Antarctica north of 76*S vanishes.


Just to start the conversation, New York might look something like Cancun, being a tropical
east coast climate:

hm south america may have a extremely cold winter,even more than north america..

[Sir Goosenseresworthie]

aside from the fact that every location would be warmer... (talking about North America)

there would be less extremes in the continental U.S. during the winter because most of the mass of North America would be closer to the equator instead of closer to the North Pole. Coastal areas of Central/Northern Canada would be Subpolar Oceanic bordering a much larger sea to the north which would mean far less variation in temperature for the entire continent. Arctic air wouldn't spill into the Great Plains like it does now.

i think the Great Plains region would become more of a desert, somewhat mirroring the Outback of Australia but on a larger scale.

That would be hell for Peru

Buenos Aires at the same latitude as present Ushuaia then would probably see very cold winters with means well below freezing and regular snowstorms/blizzards

While summers would still be warm for that latitude, due to the large landmass between 15 and 45° South, maybe with means about 15-18°C, however it would probably be also suspect to freezing nights in summer during antarctic outbreaks.

[Mr.Sir]

Peru would probably look like Chile, not hell

Also, most of the Great Plains probably would become desert. For instance, Amarillo might look like this:

hmm my climate would be tropical probably similar to places in northern south America and Latin America. our latitude would be 15 degrees north. so overall the north American continent would have a much better climate. the tropics would reach to Maine. hard to imagine places that north as tropical. Miami would be I think at 6 degrees north. also we would have much weaker and much less frequent cold outbreaks. southern Canada would be a subtropical paradise. Alaska would resemble California more I guess also.

[Mr.Sir]

My predicition for Greenville, SC at 15*N:

Good latitude, a bit too high and close to coast, but it probably would be similar to my hometown at 15*N. I agree with muslim12, and live in a similar climate to him.

Tennessee would be a tropical climate. Neversnow, 80-85 F / 27-29 C winters, and summer days probably near 100 F / 37 C. It would suck. You'd have to go to Alaska or the Canadian territories (Yukon, NWT, or Nunavut) to get a good climate. Decent climates would extend down to the latitude of the south end of the Hudson Bay.

On the other hand, Brazil's climates would be vastly improved with Dfa climates widespread in the southern part of Brazil.

Boston and Chicago will be at northern edge of tropical climate.
Boston being similar to between Havana and Miami and Chicago with larger diurnal range year round coldest month 75/55 and hottest month 93/77.
British Columbia spotted light as the new SoCal. Juneau, AK would have prolonged wet season until early in the summer and very quick dry season for a couple of weeks but everything else would be just like San Francisco especially those islands in the vicinity.
Eventually, population in North America goes highly concentrated along the Hudson Bay (Rankin Inlet, Nunavut is the biggest metro area).
