Climate change is a moral issue.
The lifestyles of (most of) the richest 10% or so of the globe comprise the vast majority of anthropogenic carbon dioxide emissions. This includes anyone with an annual income above about £10,000. These extra emissions are raising CO2 levels, thereby creating a dangerous, potentially catastrophic, legacy for countless generations to come. Carbon dioxide continues to affect climate for thousands of years. Our actions are significantly decreasing the habitability of the planet for humans and presently existing ecosystems. The ones who suffer the most are those who have done least to contribute: the poor, the young and unborn, and other species. Given that we've known about this issue for decades, there is really little excuse for continuing to pass the buck to those who come after or indulging in delay while we hope for a techno-fix to appear. The basic atmospheric chemistry was grasped in the 19th century; since the 1950s we've suspected a problem; since the 1970s we've had a pretty good idea that it was likely a problem; since the 1980s we've had solid evidence; since the 1990s, alarming evidence; and over the last decade the outlook has only grown bleaker.
We enjoy unnecessary luxuries at the cost of others' suffering, livelihoods and lives. That's a moral problem. Another way is possible. Let us embrace it with joy.
