This period might be better regarded as representing a pause in the late 1970s recovery, rather than the starting point of another cycle; [1] the 1980s expansion was also characterised by a mid-cycle slowing.

And Derek Draper and Damian McBride have been creating it in large quantities, and they're by no means the first or the most obvious examples, given the loans - for - peerages scandal, various bits of chicanery around the Iraq war and subsequent investigations (e.g. David Kelly), ministerial expense fraud (or at least it would be fraud if you or I tried the same thing on our tax returns), pretty much anything to do with Peter Mandelson and the various leaks, briefings and spin cycles that have characterised the Labour party for the last fifteen years.

More precisely, the maximum of solar cycle 24 was characterised by a rather slow and intermittent reversal of the polar field, with north - south asymmetry, meaning that the Northern polar field reversed on November 2012 and the Southern on March 2014, with both polar fields being simultaneously positive for more than a year (Sun et al. 2015).

That you have characterised their cause as magnification of small changes by system interactions doesn't rebut this view — time scale is a very slippery customer and finding the most accurate time fit for cycles of complex interactions is likely to take much longer than 30 years (the preferred time grab so far for AGW modeling)

There is a small influence on hurricane formation but there is no evidence that the NAO has long multi-decadal cycles (separate from a small forced response from the oceans or potentially from stratospheric processes)-- it is best characterised by slightly red noise.

The breakup of Pangaea was accompanied by biogeochemical disturbances including the largest magnitude perturbation of the carbon - cycle in the last 200 Myr, coeval with the now well - characterised hyperthermal, the Toarcian Oceanic Anoxic Event (T - OAE).

The defiance evident in Australia's response to the first cycle of UPR in 2011, characterised by its lack of progress and failure to implement recommendations it has previously accepted, highlights the challenges ahead in promoting international collective action as a means of protecting the human rights and health of disadvantaged minorities such as Australia's First Peoples.»
