The Guardian: "The era of climate change 'denial' is over"

"... It rarely gets noticed that climate change sceptics have actually conceded a lot of ground over recent years when it comes to the science. Many have begun to adopt a so-called 'lukewarmer' position, which means they now accept the basics of climate science but don't think it's worth investing heavily today to prevent or limit a problem that will increasingly hit home in the decades ahead.

"As I have noted many times before, I think this is a profoundly risky and irresponsible strategy. But, then again, I'm not a politician whose survival depends on a four-to-five year election cycle. Nothing exposes our species' 'future flaw' more than climate change – rarely, if ever, have the history books demonstrated a generation acting selflessly, or with sacrifice, for the sole benefit of generations to come.

"We are an extraordinary animal in so many ways, but one of our weaknesses is that we operate firmly in the present tense. We jump only when we are in imminent danger ourselves. If not, we prevaricate, delay or turn our heads away. Climate change requires us to fast overcome this flaw."
