CO2 Increase and Measurable Warming: Examining the Data

He argues the focus on recent carbon dioxide increases may be missing the bigger picture. The 120 parts per million rise over the past century and a quarter, in his assessment, has had minimal measurable effect on global temperature when urban heat island effects are properly accounted for. This isn't climate denial, it's a call to examine what the data actually shows versus what we assume it shows. He sees well-intentioned efforts to address CO2 as potentially distracting from more significant climate drivers: natural variability, cosmic forcing, and the longer cycles that have shaped Earth's climate throughout the Holocene. The question he keeps returning to is whether we're solving the right problem, or whether our focus on anthropogenic CO2 has caused us to overlook the forces that have always governed climate on geological timescales.
