The kinematics of global warming: Semiparametric analysis of warming level, rate, and acceleration
Mikkel Bennedsen, J. Eduardo Vera-Valdés
Three features of the global warming process are of central scientific interest: its level, its warming rate, and changes in that warming rate. We develop a semiparametric kinemati…
Spatial emergence of acceleration in global warming
Tanja Korsten Bugajski, Nicolai Peder Bulow Pedersen, J. Eduardo Vera-Valdes
Whether global warming is accelerating remains contested because internal variability and spatial heterogeneity can obscure changes in warming rates. Here we use a Bayesian hierarc…
Global Warming Has Been Accelerating Since At Least 1990
J. Eduardo Vera-Valdes
We investigate acceleration in global temperature, defining acceleration as a supralinear (greater-than-linear) increase over time. We develop a statistical framework to test for s…
Robust estimation of carbon dioxide airborne fraction under measurement errors
J. Eduardo Vera-Valdés, Charisios Grivas
This paper discusses the effect of measurement errors in the estimation of the carbon dioxide (CO) airborne fraction. We are the first to present regression-based estimates and…
