Collapse

This is the place for discussing the potential collapse of modern civilization and the environment.

Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

Getting real about capturing carbon from the air (www.cell.com)

Abstract

Many modeling studies depend on direct air capture (DAC) in their 1.5°C stabilization scenarios. These studies rely on assumptions that are overly optimistic regarding the cost and scaling-up of DAC systems. This can lead to highly misleading results that can ultimately impact the ability to reach climate stabilization goals.

I Just don't see the technical possibility and only see DAC as a red herring

Everything we do costs energy and nothing is 100% effective
Using ineffective ways to gather and refine oil, moving out around the world to end users, which is it in ineffective ways. And then we need energy to power carbon capture technologies that are also not 100% effective.

We're basically have an energy problem and as long as we don't solve that, we're fucked.
Yeah, yeah, using green energy to capture carbon is an option. Why don't use the green energy in the first place to get rid of the standing supply chain of oil, powering highly ineffective applications?
