How would you change your geography to improve your climate?

I would flip the Rockies to run east of Fort Collins. To compensate, I’d make them hook sharply to the East in southern Colorado ans they would continue straight north through central Canada. I’d also flatten a bunch of the mountains in western Colorado, WY/MT/NM and up into Canada. This would still allow air masses from the Gulf of Mexico and the arctic to flow in creating high variability. But being west of the Rockies, we’d get the occasional pacific storm bringing clouds, humidity and light amounts of rain.

The only downside would be the loss of the chinoook winds but these mostly occur during nighttime anyway so not a big loss.

Would look something like this:

NYC would have a hyper-oceanic climate in that scenario, probably along the likes of London temperature wise, as there is now no heat source (the Southern Plains are gone). However, it would be a lot rainier than London in all seasons and probably a temperate rainforest due to constant moist winds blowing from warm oceans in almost every direction.

Self flagellation. 

USA is too annoyingly diverse and I don't like how it features extremely arid places like the fucking sizzling Death Valley with those 57C record highs, whereas Australia can't have such impressive climatic feats! California is so unamerican-like with its beautiful Mediterranean weather and vegetation that is something out of Israel and Lebanon. You don't belong there hun! Also Arizona is like Iraq or something (can't imagine a Baghdad-esque 50C peaking city in the US), so that one can fuck off too. I'll leave them a small hot desert area. They're more suited to have cold deserts. USA itself is such a climatic little cheater. They have it all! 

To compensate things, I broadened the Gulf Coast northwardly so a milder, Sydney-like city would exist in the region (no Sydney-like climate exists in the US, oddly). Lake Michigan is now an inland sea with a river running down to the Gulf - Again, to make the inland cities have a milder Cfa climates.

I would have high mountains running along interior Perth so we could ski/snowboard in the winter
