All this nonsense is the same as the guys who have predicted 80 of the last 2 recessions. But hey, if you can exaggerate the output your model suggests that was built from faulty assumptions, incomplete data, hubris, and spans decades in time and get people to buy it and continue to fund your project, good for you.
They’re probably more unreliable as climate is far more complex than economics and predicting 50 years out with any certainty is a ridiculous notion for both.
You can put your head in the sand, but it will not save you. You must take the world on from first principles, and dive deep into the details if you want truth. Simply countering that nobody can predict what will happen is not an argument, it's a plea to stay ignorant.
Open your mind until your brain falls out. How many bromides should we exchange? Saying “there’s no proof” is better than believing everything that comes your way with 0 critical analysis. But it’s nice to feel smart.
