Warmer lows, recent increase, large increase at altitude, beginnings of a disconnect with old patterns governing temperature - this is now a classic global warming signature.

            well known. We document secular temperature changes in the Hawaiian Islands for the past ∼85 years based on an index of 21
            stations. Results show a relatively rapid rise in surface temperature in the last ∼30 years, with stronger warming at the
            higher elevations. The bulk of the increase in mean temperature is related to a much larger increase in minimum temperatures
            compared to the maximum—a net warming about 3 times as large—resulting in a reduction of the diurnal range. For much of the
            period of record analyzed here, surface temperature in Hawai‘i has varied coherently with changes in the Pacific Decadal Oscillation
            (PDO). However, in recent decades, the secular warming has begun to predominate</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.agu.org/pubs/crossref/2008/2008GL034377.shtml">greater warming trend at the higher elevations may
