Several researchers have pointed to various other indicators as evidence of «global warming», e.g., Arctic sea ice records, ocean heat content measurements, or animal and plant migration patterns.However, all of these indicators are either too short to compare recent temperatures to temperatures before the 1950s, or else are affected by non-climatic biases.

DK12 used ocean heat content (OHC) data for the upper 700 meters of oceans to draw three main conclusions: 1) that the rate of OHC increase has slowed in recent years (the very short timeframe of 2002 to 2008), 2) that this is evidence for periods of «climate shifts», and 3) that the recent OHC data indicate that the net climate feedback is negative, which would mean that climate sensitivity (the total amount of global warming in response to a doubling of atmospheric CO2 levels, including feedbacks) is low.
