How Much of an Emergency Can the Climate Actually Be?

Some say the level of concern is way overblown. Is it?

Abstract

There are different levels of climate change denial, ranging from denying its existence outright to denying that we should combat it in any fashion. These denials are often based upon some erroneous objection or objections, which are themselves often predicated upon deeply-held presuppositions which present a perceived personal risk to acceptance of climate science or the resulting recommendations.
