I suppose they should look at ocean heat content instead of questionable surface temperatures ... no?

Depends on if you care about science or political motivations or what. Both heat content and temperature are important, and both atmospheric and ocean (at various elevations/depths--including surface) are important.

The fact is, climate is variable, and it's not good news if the climate change is NOT anthropogenic, because then it means we have less control over our destiny and must simply manage reactively. But some people seem to think that it's a good thing for humans to be powerless and unable to prevent disruptions.

There are purely academic sides to this, and then practical sides. But a comprehensive budget looking at variable insolation/radiation would be wonderful to get at where the excess energy is going, if not temperature change. But even if the average is going up, there are areas that could be going down. And things like the increased snowfall from higher temperatures can have huge effects, too.

No ans. to specifics; thanks anyway ...

Got to take off now.

“and it’s not good news if the climate change is NOT anthropogenic”

It’s not, so you’d better proceed on that premise. If water vapor - the dominant greenhouse gas - is included, humanity’s contribution to total greenhouse gasses is .02%. That is 2 parts in 10,000.

On the other hand, the Sun provides very close to 100% of the heat input for this rock. Slight solar variability can very easily swamp most other contributions, certainly including the miniscule amount contributed by CO2. That is occurring now, as the current solar minimum stretches to near-record lengths. Both last winter and this fall we’ve seen unusual amounts of snowfall. Guess what, snow and ice are major sources of NEGATIVE temperature influence, since so much extra energy is reflected into space. You’ll also note that the northern icecap continues to grow since the minimum of 2007, and the southern ice extent is well above the cherry-picked baseline.

Looking forward, the consensus among solar astronomers is that the coming cycle, 24, will be longer and weaker than cycle 23 - meaning even more of a cooling influence than we’re seeing now. That should mean something like 15 more years of cooling, at a minimum.

Also keep in mind that most likely a new Ice Age will come at some point. Any warming is a good thing.
