The American Association for the Advancement of Science joins the ranks of the alarmists, calling global warming "a growing threat to society" that should be countered with "rapidly reducing greenhouse gas emissions." AAAS says:

The average temperature of the Earth is heading for levels not experienced for millions of years. Scientific predictions of the impacts of increasing atmospheric concentrations of greenhouse gases from fossil fuels and deforestation match observed changes. As expected, intensification of droughts, heat waves, floods, wildfires, and severe storms is occurring, with a mounting toll on vulnerable ecosystems and societies. These events are early warning signs of even more devastating damage to come, some of which will be irreversible.

Delaying action to address climate change will increase the environmental and societal consequences as well as the costs. The longer we wait to tackle climate change, the harder and more expensive the task will be.

I’m waiting for a representative from the Sensible Center to rise up and scold AAAS for its intemperate language.
