That climate change is an important issue these days is hardly a controversial statement, as a citizen of a western democracy I am encouraged to be ‘climate smart''. But is that a real solution to a complex issue? In this essay three major actors on the global climate change arena are investigated in relation to each other: Social movements, scientific perspective (IPCC) and policymakers (UN). The idea which inspired this essay was the notion that the policy decided upon by the world leaders during the climate summit in Copenhagen, Cop15, would stand further from the scientific view of climate change in relation to sustainable development than what the social movements'' demands are. Furthermore, this essay has a didactic perspective and aim to illuminate how the climate change issue can be used within the school subject social studies. Despite that there was no deal part the this essay shows that social movements have a close, but critical relationship towards both world leaders and politicians and to the scientific view of climate change, and is of interest to anyone who would like to understand the climate change issue from different perspectives.
