Air Conditioning. Aka "La clim'" in France.
For some context: the conversation about climate change in general, and the recent heatwaves in particular, has been (quite cynically, but cleverly) reframed by far-right parties to be all about "we need to put AC in France to survive heatwaves".
This is smart because it addresses on the physical sensations of people (it's the third heatwave since end of may, and counting), it has an element of truth (AC is critically lacking in schools), it seems much more "down to earth" than the grand plans of "decarbonization", and it makes other political parties look out of touch (the left and greens have been criticizing AC because of the energy impact.)
Of course, this is both "smart" and incredibly cynical, given that the far right has been on the edge (or not so much on the edge) of climate denial for years. So year, "climate changes is not real" turned into "why didn't they put AC everywhere ?" then "vote for us, we'll put AC everywhere !"
This is also very short sighted.
But I guess no one has found a way to ask our future president (Marine Le Pen, twice convicted of embezzlement, waiting to know if she will have to run for President with a "jail from home" tracker, etc...) what exact amount of "putting AC and kicking immigrants out" is going to avoid Fontainebleau forest from burning.
(Also, since those people are incredibly "lucky", I can only imagine what will happen if we learn that the fire was volontary, and the arsonist was an immigrant... )
The only "consolation" is that El Nino is coming back, and she takes office on the 15th of may, so _she_ will have to deal with at least a couple heatwaves between 2027 and 2037...
We do have quite a similar discussion here in Germany.
Back in the day, everyone used fossil fuels to heat their homes. Back in those days, AC was frowned upon as inefficient, wasteful and decadent. Something only Americans did. The greens despised them for ecological reasons. The right despised them for moral reasons.
Then the public came to know about climate change and it was decided that people should transition to using heat pumps for heating their homes. Because heat pumps are efficient, green and a necessary sacrifice of money you have to do to combat climate change.
Now with this year's heat wave, suddenly there was a discussion even among the greens about having AC in buildings as a necessary adaptation to rising temperatures. And demands by the right to get rid of the AC stigma and deploy AC everywhere. And back in the corner, there were experts laughing out loud, because a heat pump is just an "evil" AC running in reverse. Has been all along. The only problem is that usually heat pumps were deployed in such a way that you couldn't use them to cool in the summer...
Which imho goes to show that the public urgently needs more scientific and technical literacy.
