How much colder would the WWII been if all naves had there builds upto 1942 in 1939

Lets take a look at how the weather was changed by naval Actions in WWII . How much more would it of changed if in 1939 all the nations had the ships laid down and build up to Sept 1942 in 1939 .
If the fleet of 1939 could change the weather how much more would if they were they size they would of been in Sept 1942 .

My first impression is that this would have allowed Germany to initiate all-out unrestricted submarine warfare from the start, and potentially starve out Britain since the counter-measures haven't been developed and essentially lag 3 years behind now. Of course, tactics and control within the KM are not going to be as well developed, but I think that loss would be only a fraction set aside greater Allied merchant losses.

Would having the Bismarck, Tirpitz, Hipper, Blucher and Prinz Eugen all ready for the Norwegian campaign give any greater odds in favour of the Germans, or would it simply mean the British too can deploy more, better and newer battleships and carriers and actually make the possibility of a fleet battle, with German annihilation, more likely?

That "article" is rather long on sensationalism, and short on science, to be frank. The author doesn't seem to have a very good grasp of just how massive oceans are and ships aren't, among other issues.

The fleets of 1942 would have roughly the same impact on ocean temperatures that the fleets of 1939 did, which is to say, none at all.

As for the impact of having Bismarck, Tirpitz, and three cruisers all involved in any particular operation, if the Germans concentrated all of their capital ships in one area, the Royal Navy would make a point of showing up in force. If that happens, well, the German ships are good, but they aren't *that* good. Leaving one of the Nelsons for the Med, and two of the KGVs for the Far East, that would still leave two German battleships ships facing five British battleships and at least one carrier. Not good odds for the Germans, to say the least.
 
"since the counter-measures haven't been developed and essentially lag 3 years behind now."

I am not sure this is a safe assumption. The scientific underpinings of Radar, Sonar (ASDIC in Britain) and homing torpedo predate 1939 and the allies would recognize that they must imporve anti submarine weapons and tactics. I think it is more likely that the 1942 vessels would be equiped pretty much as they actually were. Undoubtedly there would have been a learning curve but that would apply to both sides.

Aslo remember that in this alternative 1942 the Germans would not be operating from the French ports. That will reduce effective operating times for the U boat.

Since the British will get all 5 King George Vs and all four Illustriouses, then I predict only limited benefit to the Germans.
