Sea level rise acceleration (or not). Part V: detection & attribution

by Judith Curry In looking for causes, I have applied the ‘Sherlock Holmes procedure’ of eliminating one suspect after another. The procedure has left us without any good suspect. Thermal expansion was the candidate of choice at the time of … Continue reading

Will advances in groundwater science force a paradigm shift in sea level rise attribution?

by Jim Steele  A better accounting of natural groundwater discharge is needed to constrain the range of contributions to sea level rise. The greater the contribution from groundwater discharge, the smaller the adjustments used to amplify contributions from meltwater and … Continue reading

Observation-based (?) attribution

by Judith Curry Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases. These findings are stronger than those of the Intergovernmental Panel on Climate Change, the United Nations group that defines the … Continue reading

On the attribution of flood peaks

by Judith Curry The hypothesized link between a warming climate and increased frequency and magnitude of floods goes something like this:  a warmer climate is associated with more water vapor in the atmosphere, which means more rainfall and more floods. … Continue reading

Climate Change, Extreme Weather Linked(?) at Last

by Judith Curry The title for this post comes from a post at Pew Climate, highlighting a big three-part series featured on  to explain the link between climate change extreme weather.

Is Extreme Weather Linked to Global Warming?
