I believe wooden building of the sort described in the article can be a solution to climate change, in the normally understood usage of the word solution, if combined with a time machine.
Agreed, time machine is probably the only hope. Now that we have melted large parts of polar permafrost and the arctic is on fire, "fixing" climate change is not really possible. More about coming to terms with what we've done and how to cope with the new world we have created. My bet, it won't be pretty.
