I've given you numerous explanations as to why east vs west doesn't matter ... yet you're the one who's still confused.
Hudson Bay is a small, shallow sea surrounded by land. Therefore, unlike the deeper, more open North Sea, the temperature would cool down faster at Hudson, and it gets iced over, completely eliminating any moderation effect.
Now you try this: if east vs west matters, as you say, then why aren't record lows in Australia colder on the east coast than on the west coast? South Africa? South America? How about India?
Its not the North Sea! Its the gulf stream, its the Atlantic that 'protects' Western Europe from the cold.
Yes, I know...I’m arguing against Texyn who thinks “barriers” like the North Sea or the Rocky Mountains protect west coasts of North America and Europe from cold temps.

Eastern North America has the entire Arctic Sea to its north. It’s not small or shallow. Your “barrier” theory just doesn’t work.
Another question: why is Ukraine so much milder than points at the same latitude further east? If you look at a map you’ll see there’s no North Sea “barrier” protecting Ukraine from Siberian air masses, so why is it milder than the east coast of China many degrees of latitude south? Couldn’t have anything to do with east-west could it?

Record lows in Eastern South America are colder than in the Western coast, Mar Del plata at 38S for example has a record low of -9.3C/15.3F, while Puerto Montt at 41S hold -7.1C/19F.
So once again: whether or not winter cold is severe depends on the presence or absence of geographic barriers. East vs west does not matter.
This is wrong! East and West does matter. The Polar and Subtropical Jet Streams with their Rossby Waves moving air masses upon the globe have a much greater impact on a region's weather than any topographic feature. The major effect of topography is the amount of precipitation an area receives, (i.e., rain shadow).
"It's never hot in California, or at least Southern California, during the summer."
Heck, I'm telling you I'd rather spend an entire summer in New Orleans than one summer day in the Inland Empire.
Not sure who said it's never hot in SoCal. I lived my whole life there until I retired last year and moved to North Idaho. One of the primary reasons for moving was the summer heat. My last full summer there, it was triple digits for weeks on end. Final straw was the day I took a bike ride and limped home with heat exhaustion. Checked the current weather when I finally got home and the temperature was 104ºF/40ºC. I would call that "hot". And, this was in Los Angeles County, (the Antelope Valley).
Eastern North America has the entire Arctic Sea to its north. It’s not small or shallow. Your “barrier” theory just doesn’t work.
Sure it does. The cold air masses that affect Eastern North America form over land, mainly in Canada. Or they can come from Siberia, through which they cross the land bridge in the Bering Strait area.

First off, there's much more land to the north of China than there is at the Ukraine longitude. Second, there's the Ural mountains to the east of Ukraine that can dampen the cold than tries to bleed west from Siberia. And third...Ukraine isn't milder than China's east coast at all.
I mean, different cold snaps have their differences in trajectories. Like with here in the US, I can pull up many instances when the West Coast got the brunt of cold weather compared to the East. Thus, maps for individual years won't really be that telling. Even so, the 1997 map doesn't look as convincing as the 2007 and 2011 maps.
But in any rate, compared with the western half of the continent, eastern Australia looks to have more dramatic elevations, and at a closer location to the coast. So that plays a role in making the mildness "narrower" on the eastern coast than the west. On the flip side, the area west of the Dividing Range on to the center looks like the largest expanse of lowland on the continent ... essentially, a "bowl" where temps can really bottom out during radiational cooling events.

Mar Del Plata looks like it has a lot more land to the S/SW than Puerto Montt does.
