Global Warming Science
According to the IPCC, the climate models only need anthropogenic CO2 after 1970 to reproduce the past warming trends. In Hawaii the warming stopped in the 1970s - since then there has been no warming. The temperatures and sea level fluctuations correlate well with the Pacific Decadal Oscillation (PDO), but not with CO2. See the new Regional Summary - Hawaii page for more detailed info on Hawaii's climate.
