Adaptation to a warmer and less predictable climate is a no brainer, since it will be practiced anyway, with or without policies. Some will do it well, others less well.

Adapting through proactive policy measures (way before the feared outcomes happen) may be a pointless and costly endeavour and may even prove counterproductive.

Mitigation policies: everyone understands (or should understand) that the containment of further radiative forcing caused by the emission of greenhouse gases needs to take place in anticipation of the feared warming. But the present resources to engage and the cost to pay for this is not immediately rewarded by benefits that are expected only at the turn of the century. No current executive leader will be around to claim such late victory.

So, humanity may enjoy the benefits of mitigation at the same time that it will have anyway adapted to a changed climate.

Currently, the sole rationally acceptable way of justifying the cost of mitigation (mostly a gigantic electrification of all human activities) is a well understood sense of the "social cost of carbon". This means the cost of a nefarious climate at which humanity would neither have adapted nor taken preventive mitigation measures.

But, it will have adapted!

In addition, there is no consensus on this social cost of carbon that depends highly on speculative scenarios. There is not much more consensus about the effectiveness and efficiency of the mitigation policies.

This explains two points:

- current climate policies can only remain founded on fear, not on reason.

- policy implementation remains well below the stated goal of net zero emissions by 2050, as the motivation lacks true consensus.

The toughest task in a strategy is setting objectives, all the more so if they prove unattainable.

Seems like China took climate change seriously while US/EU only pontificates!
