Climate Alarmism Skeptics are not Climate Deniers, and they do not deny that the average atmospheric temperature has risen, as the article states. Instead, they see the rate of change as being very slow, giving humans plenty of time to adapt. Whether this slow change constitutes an actual crisis is the matter being contested.The direct warming from doubling atmospheric CO2 is only about 1.1 degrees Celsius, so much of the debate hinges on natural feedbacks. There are many feedbacks, both positive and negative, whose effects are not fully understood and are controversial.
