    A new study shows that ocean heat content is the best way to measure global warming.

    Ocean temperature as a vital sign revealing Earth's warming

    This study shows that the temporal evolution of ocean heat content has a relatively high signal-to-noise ratio; therefore, it requires 3.9 years to separate the global warming trend from natural variability. Similarly, for sea level rise, 4.6 years are sufficient to detect the climate change signal. By contrast, owing to weather, the El Niño-Southern Oscillation and other natural variability phenomena embedded in the global mean surface temperature record, scientists need at least 27 years of data to detect a robust trend. 

    The black line is ocean heat content, the pink is CO2 level, blue is CO2 measured at Mauna Loa.
