There is a way. Right now most people (myself included) don't think there is any need to do anything, despite constantly hearing from the media and commenters on HN that the sky if falling.

If you are convinced a crisis is coming and want to make a significant contribution, try to develop a workable policy proposal and a convincing case of why it would be a good idea. I have invested a few weeks researching this topic and found nothing I would feel comfortable sharing with skeptics and saying, "here's a good case that a CO2 tax would be beneficial" (or something similar).

An example of an unconvincing case is the recent report from the US government; they claimed GDP will be 10% lower in 2100 if we don't make drastic cuts to CO2. The issues with it are (1) Our GDP in 2100 will be 10X what it is now, so 10% is irrelevant. (2) The cost to cutting CO2 drastically will reduce GDP even more. (3) The report assumed worse than the worst case scenario from the IPCC, i.e. it's very unlikely.

The value of any report that predicts future economic outcomes more than 1 political (or economic) cycle into the future asymptotically approaches zero with the length of prediction term.

Humanity & most people are notoriously bad at making long term predictions.
