A search for scale in sea-level studies
C.E. Larsen, I. Clark
2006, Journal of Coastal Research (22) 788-800
Many researchers assume a proportional relationship among the atmospheric CO2 concentration, temperature, and sea level. Thus, the rate of sea-level rise should increase in concert with the documented exponential increase in CO2. Although sea surface temperature has increased in places over the past century and short-term sea level rose abruptly...
