The physicists Harald Lesch and Axel Kleidon are angry about the widespread unwillingness of broad political circles to understand how nature works - a text that shakes up Harald Lesch and Axel Kleidon are annoyed: Time and again, those responsible in politics and business try to pretend that the laws of nature can simply be ignored. Politicians like to believe in technical Harry Potter magic tricks. That is why the two physicists speak plainly here: nature does not negotiate, it is not a party, it does not allow itself to be co-opted. They explain briefly and concisely what efficient energy use and climate protection mean, why energy is devalued and what measures would be taken by a policy that has understood how nature works.
