WHILE it is generally agreed that there has been an increase in global temperatures over the last 150 years there is much debate as to how continuous or sporadic this warming has been. I have suggested that understanding could be aided by focusing on one or a few reference stations – particularly given trends in global average temperature is potentially an artefact of how data from stations across the world is combined and then adjusted.
A technical paper, Secular temperature changes in Hawai‘i, published just last year in Geophysical Research Letters indicates there has been recent warming on the island of Hawaii and this has been most evident at high elevations. While the text in the paper emphasis this warming and suggests a potential negative impact, the charts in the same paper suggest that despite the increase in temperatures over the last 30 years, Hawaii is no warmer now than it was in the 1930s.
