The debate about climate change is almost thirty years old. Endless time and energy has already been spent in unproductive ways: discussing whether climate change actually exists, whether humans contribute to global warming, whether the risks that come with global warming are real and then whether we need to cut down on emissions.
These questions are settled, but many important questions remain to be open for discussion in climate science and climate politics. The upcoming summit in Paris draws our attention towards tackling the challenges associated with climate change in the present, rather than repeating discussions from the past. Part of this is to reclaim the attribute of being “skeptical” as an essential feature of good science. Yet, wise scientists will attempt to direct their skepticism to hypotheses which are not properly grounded in empirical evidence. Continuing the old debate is only in the interest of those actors who feel they need to protect their vested interests in oil, coal and gas and the attached industries with the aim of blocking effective limits to our carbon emissions.
