Trude Storelvmo is principal author of the YCEI-funded study in Nature Geoscience which finds that “transient” climate sensitivity, the amount of temperature rise we will experience when atmospheric CO2 doubles over preindustrial levels, is higher than reported by many previous studies. To date, warming due to CO2 emissions has effectively been ‘masked” by widespread sulfate pollution. Studies that haven’t fully accounted for the cooling effect from pollution particles have therefore erroneously concluded that climate is less …
Peter Rhines visits us from the University of Washington’s School of Oceanography. His research interests include: High latitude climate: field observations in the subpolar Atlantic; Geophysical Fluid Dynamics laboratory, theory and observations of waves and circulation; atmospheric dynamics; oceanic eddies and their relation with the general circulation; teaching environmental science and its relationships with human activity.
We apply econometric methods to climate observations in order to disentangle the contribution to modern climate change from greenhouse gases and aerosols, both constituents of the atmosphere which been increasing in concentrations in response to industrial activity. Our preliminary results suggest a substantial masking of the greenhouse warming due to the compensating cooling effect that anthropogenic aerosols have on the Earth-atmosphere system.
