It is curious that the following things are never admitted as «facts about the world,» but here goes: the observer would note of all of these systems that they undergo oscillations within apparent parameters and occasionally flip into new regimes; they often demonstrate novel emergence; and that increased forcing, whether of native elements or exotic ones, increases the rates of oscillation and catastrophic shifts, sometimes after a quieter period of sub-threshold build - up.

As a general observation my claim is, however, that every scenario that leads through scientifically justifiable arguments to very severe consequences over very long periods does that also over a period of about 100 years.

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.

Observations for that period are well within the 2 - sigma model range, and mostly within the 1 - sigma range, with two 10 - year excursions above / below the model mean at about 1905 - 1915 and 1935 - 1945.

True, but fails to explain why the longer - term mean about which those cycles fluctuate is trending up other than curve - fitting an «approximation by three sinusoids of periods 1000 years, 210 years and 60 years,» ANSWER: The curve fitting exercise is labeled as such «heuristic»; the lengths of the cycles are from other observations, some displayed on figures 5 - B & C; only the amplitudes and phase of the 215 and 60 years sinusoids are subject to optimization; Singular Spectrum Analysis has been applied by Diego Macias et al (note 18) to the HadCRUT series with equivalent results, and among many others by Liu Yu et al..

«The assessment is supported additionally by a complementary analysis in which the parameters of an Earth System Model of Intermediate Complexity (EMIC) were constrained using observations of near - surface temperature and ocean heat content, as well as prior information on the magnitudes of forcings, and which concluded that GHGs have caused 0.6 °C to 1.1 °C (5 to 95 % uncertainty) warming since the mid-20th century (Huber and Knutti, 2011); an analysis by Wigley and Santer (2013), who used an energy balance model and RF and climate sensitivity estimates from AR4, and they concluded that there was about a 93 % chance that GHGs caused a warming greater than observed over the 1950 — 2005 period; and earlier detection and attribution studies assessed in the AR4 (Hegerl et al., 2007b).»

This test found that the «no - Australia» southern hemisphere temperature was typically 0.10 — 0.15 °C cooler than the full southern hemisphere dataset between about 1878 and 1893, suggesting that Australian temperature observations incorporated into the HadCRUT4 dataset were likely to be unrealistically warm during this period.

Which leads to another observation about natural global warming and climate change: past empirical evidence from earlier in the 20th century confirms that Earth's natural climate oscillations can produce periods of significant temperature change increases that even exceed the most recent temperature climate change.
