The GRACE observations over Antarctica suggest a near - zero change due to combined ice and solid earth mass redistribution; the magnitude of our GIA correction is substantially smaller than previous models have suggested and hence we produce a systematically lower estimate of ice mass change from GRACE data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged sea level change, or about 6 % of the sea - level change during that period.

The crux of Bates» claim is that NOAA, the federal government's top agency in charge of climate science, published a poorly - researched but widely praised study with the political goal of disproving the controversial global warming hiatus theory, which suggests that global warming slowed down from 1998 until 2012 with little change in globally - averaged surface temperatures — a direct contrast to global warming advocates» claim that the earth's temperature has been constantly increasing.

Our evidence for this is based on the observation, previously noted by Pallé (2005), that the changes in globally averaged low cloud cover are strongly anti-correlated (r = − 0.79) to variations in overlying cloud cover (Fig. 3).

As seen in Figure 4 - 3, the ocean warming occurred in the later years of the record with little change in globally averaged ocean heat content prior to 1997.

Doing this on a year - to - year basis shows NO apparent correlation with the absolute «globally and annually averaged land and sea surface temperature anomaly» (i.e. HadCRUT3), but does show a weak correlation with the CHANGE in temperature from the previous year, for example:

These feedbacks are the primary source of uncertainty in how much the earth will warm (side note: the question that most climate scientists who study the forcing due to CO2 try to answer is, how much will the long - term globally averaged surface temperature of the earth rise due to an rapid rise of CO2 to twice its industrial level, that is, 270 ppm to 540 ppm; it is currently about 380 last time I checked, and rising at ~ 3ppm / year, although this rate of change appears to be accelerating).
