Massive crop failures across poorer equatorial regions have become increasingly regular.
Longer, harder, droughts, and then extreme water events that can’t retain much of the water causes other problems beyond just floods.
Economists have historically proven to be extremely inaccurate at predicting long term patterns. They also have a strong bias in favour of business, so always find “supporting evidence” for almost any choice creating immediate gains for business.
An easy measure is: has any major economic “study” ever supported raising taxes for businesses or the rich? Have they supported investing in employee welfare? Universal healthcare? Etc
In countries that have done this, and thus actually measured the outcomes, they have found things have improved for the majority of people.
In countries that have followed the “reduce taxes and services” to improve society we have for decades seen the exact opposite, and yet economists still claim that life will improve for people. Again, this is despite decades of direct contrary evidence.
Economics is a fiction, the only actual supported piece of economic theory is supply vs demand. That’s it.
