There are, however, caveats: (1) multidecadal fluctuations in Arctic — subarctic climate and sea ice appear most pronounced in the Atlantic sector, such that the pan-Arctic signal may be substantially smaller [e.g., Polyakov et al., 2003; Mahajan et al., 2011]; (2) the sea - ice records synthesized here represent primarily the cold season (winter — spring), whereas the satellite record clearly shows losses primarily in summer, suggesting that other processes and feedback are important; (3) observations show that while recent sea - ice losses in winter are most pronounced in the Greenland and Barents Seas, the largest reductions in summer are remote from the Atlantic, e.g., Beaufort, Chukchi, and Siberian seas (National Snow and Ice Data Center, 2012, http://nsidc.org/Arcticseaicenews/); and (4) the recent reductions in sea ice should not be considered merely the latest in a sequence of AMOrelated multidecadal fluctuations but rather the first one to be superposed upon an anthropogenic GHG warming background signal that is emerging strongly in the Arctic [Kaufmann et al., 2009; Serreze et al., 2009].

Your observation that paleo records tend to miss the shorter term variations seen in instrumental records is interesting, as this weakness would lead to doubtful conclusions that past centuries saw less climate variability than we now observe (Shaun Lovejoy article in Climate Etc. in Januaryclimate variability than we now observe (Shaun Lovejoy article in Climate Etc. in JanuaryClimate Etc. in January 2013).

Instead, Abbott chose to dig himself deeper, extending his denialism on bushfires and further claiming that the observation of record high temperatures is not evidence of climate change.

This recent shift towards more intense and frequent El Niños is related to the recent increase in dry areas around the world.5 However, past observations and reconstructions of El Niño events from non-instrumental records such as corals show that El Niño events naturally fluctuate in magnitude and frequency over time, and this has been demonstrated in long climate model simulations of past and future climate as well.6

So using the criteria of «noticeable» climate change that would affect humanity and nature, that can be reasonably validated against the benchmark of the 1920 - 40 period by such records as instrumental and crop, or observations, and as being of a duration of at least one decade, we have some 15 decadal episodes of «noticeable» climate change, (up and down) between1538 and 2012.
