Understanding and Reconciling Different Estimates of Global Warming

Reconstructing past global temperatures is complicated by changes in instrumentation, measurement practices, spatial coverage, and other factors. This has led to a number of divergent estimates of the warming over the 20th and early 21st century, with particularly large differences around the WW2 era and over the past decade. This talk will assess different observational records, and look at independent ways to try and determine which are most accurately capturing changes in global temperatures of the surface, atmosphere, and oceans over the past century.
