The assumption underlying a lot of the recommendations for actions in response to climate change is that the overwhelmingly dominant factor is CO2 emissions, and that reducing CO2 emissions is the only and/or best way to walk back from the consequences. Neither is true. For one, CO2 emissions reductions may not be realistically possible with our current technology and geopolitical situation. More importantly, there are other factors at play (such as soot changing the albedo on snow/ice covered arctic areas) and it's likely that there are dynamic effects at play which cannot simply be walked back by reducing CO2 atmospheric concentrations.

It's very likely that we're already locked into a certain level of sea level rise over the next few hundred years due to the breakup of antarctic ice sheets. This may not be something we can stop even if we could reduce atmospheric CO2 to whatever level we chose tomorrow. We need to look at ways of mitigating the impact of climate change and environmental change (whatever the cause) in the future even as we look at ways to try to reduce the negative impact of human activity on the climate and biosphere in general.

There are far too many people who look at pollution and climate change through an essentially religious lens. As though CO2 emissions are sin, and the only thing to do when caught sinning is to stop sinning, or at least sin less. This is an incredibly immature way to handle the complex relationship between mankind and Earth's environment.
