But CO2 emissions haven’t!
John Abraham and Dana Nuccitelli write in the Guardian:
The small fraction of that warming that’s expressed by changes in surface air temperature does appear to have slowed over the past decade. Research by Masahiro Watanabe of the Japanese Atmosphere and Ocean Research Institute suggests this is mainly due to more efficient transfer of heat to the deep oceans. Consistent with model simulations led by NOAA’s Gerald Meehl, Watanabe finds that we sometimes expect “hiatus decades” to occur, when surface air temperatures don’t warm because more heat is transferred to the deep ocean layers.
Research on the causes of slowed surface air warming is of course ongoing. The question remains how much other factors have contributed to the surface warming slowdown. For example, aerosols (particulates released from volcanoes and from burning coal and diesel that cause cooling by reflecting sunlight) and low solar activity over the past decade likely played a role as well. However, Watanabe’s research suggests that these factors can’t explain most of the slowed surface warming, which his study attributes mainly to a more efficient transfer of heat to the deep oceans.
The warmist hypothesis has always emphasized warmer air temperatures. As they now are forced to admit, that has not happened to the degree forecast. Now they want to be excused from their error so they can foist a new hypothesis on us. No thanks!
