Scary stuff...
“Warmest on record” shouldn’t scare you, on a planet that’s 4.5 billion years old. When the “record” only goes back to 1955.
There is a 500- 800 year lag between atmospheric temp and ocean temps. Given how warm, and how long it was warm in the medieval warm period, the oceans now should be.

While alarming, that’s not necessarily the scariest part. This article from Scientific American says “research suggests that the oceans are heating up about 40 percent faster than previously estimated by the IPCC. Since the 1950s, studies generally suggest that the oceans have been absorbing at least 10 times as much energy annually, measured in joules, as humans consume worldwide in a year.”
It’s the second part of that this is truly scary. That’s an enormous amount of energy.

A nuclear bomb also has an enormous amount of energy that is every bit as scary and has a higher probability of going off before the artic melts and causes you any harm.
I'm trying to put this into perspective for you...

Ocean cycles range from seasonal, annual, centennial to millennial. Atmospheric and ocean temperature are not linearly correlated and the timescale is certainly not 5-800yrs. However, that's off point in the cited research, which is indicating a trend and its potential consequences within our lifetimes for which the climate on record is basically all that matters. The planet will survive either way.
For the record, there were no oceans for ~4.5bn, nor temperature on scales we would care for given other factors through earth's history.
There is absolute proof of lag between atmospheric temps and ocean temps.
Do you actually think the oceans that are such a large part/mass of our planet, and as deep as 7 miles could heat up because of c02 that fast? Why if co2 has been many times higher than our current level didn’t they boil over. The ocean’s have 99% control over our climate. And the sun’s output, solar activity, and our planet’s relation to it, Milankovitch, control the oceans. This is proven and traceable throughout our history. Let’s not confuse much shorter cycles, like ocean temp/oscillations, pdo, amo, mjo, which control climate more on a weather timescale, with ocean temps, Milankovitch, and solar cycles, which control climate.

I like
The Arctic is not melting, and hasn’t melted away already as was predicted to by the IPCC. As a matter of fact and physics, summertime melt is virtually unchanged. It’s only wintertime which is smaller, because of warmer oceans, which make more moisture. And moisture effects temps exponentially the colder it is.
Add to that the amo shows to be flipping to cool phase, and already shows an arctic rebound.
