It's not lecturing. It's pointing out that there is no realistic scenario in which western countries can prevent CO2 from getting to dangerous levels. Even if emissions went to zero, it would only push the timeline back a few years
This is the problem I have with people who claim to care about the catastrophic impact of climate change. It's more about claiming moral victory over western countries than it is about actually working to reduce the CO2 in the environment. If someone was about to destroy the world, wouldn't your main focus be on preventing that to happen rather than Monday morning quarterbacking the last 100 years of industrialization?
