Annual carbon dioxide (CO2) and methane (CH4) change rates lag behind changes in sea ice extent by 7 months and 5 months, respectively. This robust correlation is consistent with the conclusion that CO2 (and CH4) changes are responsive to temperature, not the other way around. It is commonly believed that the annual “squiggle” of the … Continue reading New Paradigm-Shifting Study Finds Annual CO2 Flux Is Driven By Temperature-Dependent Sea Ice Flux
