Changes in Northern Hemisphere stratospheric variability under increased CO2 concentrations by Bell, C, Gray, L, Kettleborough, J

“…Equilibrium climate change simulations employing forcing of two and four times pre-industrial CO2 are presented, with particular focus on the temperature response of the Arctic lower stratosphere during Northern Hemisphere winter. High CO2 loading provides the ability to attain the statistical significance of any response, typically a problem given the large component of interannual variability common to the region. …”
