Sucking carbon dioxide from air is cheaper than scientists thought
I worry that well-meaning efforts at mass climate engineering will cause far more harm than letting nature run her course.<p>I&#x27;m not convinced there is a causal relationship between human activity and CO2 levels or average temperatures (ignoring urban heat island and similar effects). Sure there is a correlation, but we all know what that means. The kind of atmospheric engineering that scares me is exactly the tool that would be required to show a causal relationship.<p>Another point of concern is that none of the doom and gloom predictions are made by any climate model. All a climate model can do is make predictions about, well, climate. It takes an economic or some other sociological model to predict how that change in climate will affect human beings and societies, and what the costs (and benefits!) will be. Even if you trust the climate models 100% you&#x27;d be a fool to trust the economic or sociological models. How can one rationally justify an intervention is worth the cost when one can&#x27;t know the cost of what is being prevented?
