Contributor(s): Professor Kevin Anderson | Despite high-level statements to the contrary, there is little to no chance of maintaining the global mean surface temperature increase at or below 2 degrees Celsius. Moreover, the impacts associated with 2°C have been revised upward sufficiently so that 2°C now more appropriately represents the threshold between 'dangerous' and 'extremely dangerous' climate change. Kevin Anderson will address the endemic bias prevalent amongst many of those building emission scenarios to underplay the scale of the 2°C challenge. In several respects, the modeling community is actually self-censoring its research to conform to the dominant political and economic paradigm. However, even a slim chance of 'keeping below' a 2°C rise now demands a revolution in how we consume and produce energy. Such a rapid and deep transition will have profound implications for the framing of society, and is far removed from the rhetoric of green growth that increasingly dominates the climate change agenda.
