Use this business cycle graph to plan your sector investing strategy around the natural phases in the economic cycle Investors have a horrible track record of timing the market, trying to buy low and sell high.

But even earlier readings can provide a record of natural climate variation caused by volcanic eruptions or cycles in ocean circulation.

While both Harvey and Irma «are record - setters, NOAA doesn't see a «clear existing signal in storm data» going back to the 1800s that proves the two storms are part of a departure from the cycle of natural variability.

In order to understand Earth's recent temperature record, it's essential to understand the impacts from these natural cycles, says Byron Steinman, a paleoclimatologist at the University of Minnesota's Large Lakes Observatory in Duluth and lead author of the new study.

A detailed, long - term ocean temperature record derived from corals on Christmas Island in Kiribati and other islands in the tropical Pacific shows that the extreme warmth of recent El Niño events reflects not just the natural ocean - atmosphere cycle but a new factor: global warming caused by human activity.

Therefore, IMHO, it would be closer to the truth to call WUWT a «skeptic» site that calls into question exactly how much the mean temperature has increased since the advent of the thermometer record in the late 1880's, how much of that is due to human activities and how much to natural cycles not under our control, what dangers rising temperatures may pose to human life and civilization, and what technologically and politically doable actions may be taken to reduce human - caused warming, and our dependence on foreign sources of fossil energy.

Last summer's record loss of ice was due to a combination of natural cycle and global warming factors: «more greenhouse gases, an unusual wind pattern, and warming of the ocean water in regions with reduced sea ice.»

Since it is unclear how «natural forcing» produces these interglacial cycles, one really must wonder why one would care that one can not reproduce an undefined insignificant period of the record with «natural forcing factors».

For forecasts of the timing and extent of the coming cooling based on the natural solar activity cycles — most importantly the millennial cycle — and using the neutron count and 10Be record as the most useful proxy for solar activity check my blogpost linked above, The most important factor in climate forecasting is where earth is in regard to the quasi - millennial natural solar activity cycle which has a period in the 960 — 1020 year range.For evidence of this cycle see Figs 5 - 9.

Where is the evidence of some other natural forcing, like the Milankovich cycles that controlled the ice ages (a fine historical example of a dramatic and regular climate cycle that can be read in the ice core records taken both in Greenland and in the Antarctic)?

E. Even the official «global temperature» record, which has been adjusted to promote global warming hysteria, has not followed the pattern of increased atmospheric concentrations of CO2, but rather has followed the pattern of natural causes, primarily solar activity and ocean cycles.

When looking at longer cycles of variability, you have to be careful not to include solar variation and aerosol forcing that are not part of natural variability, and that seem to account for a lot of the long - term effects in the temperature record.

In short, radiative forcing from GHGs and volcanic aerosols explains a great deal of the land record with a residual that follows a natural cycle: AMO.

Back in the old days, before the land temperature records were subjected to bouts of data diddling to conceal the awful truth, one could scrutinise the graphs back to 1850 and clearly see the alternate warmer / cooler regimes in roughly 30 - year cycles that even the dullest brain could imagine was a manifestation of natural cycles.

In fact the ONLY warming in the whole of the satellite record has come from natural ocean cycles and solar driven El Nino events.

Broecker also put the 1910 - 1940 warm phase in the context of 80 - and 180 - year natural variability cycles that are typical of what had been happening over the past 800 years according to Greenland records.

Pine beetles are a natural part of the life cycle in Western forests, but this outbreak, under way for more than a decade in some areas, is by far the most extensive ever recorded.

gives an idea of how these multi - secular / millenarian natural cycles may appear by attempting a reconstruction of a pluri - millennial record proxy model for the temperature in central Greenland.

I do think that there is a broad consensus that there likely is an effect from increased SST, but that so far it is not sufficiently significant to be visible in the impact record, while lots of other things are, including the well known natural decadal cycles affecting hurricanes, flood defenses and increasing population and property values.

Given the lack of detailed proxy records to trace simultaneously biochemical baselines and length of food webs, assessing the extent to which biogeochemical cycling and community structure in pelagic ecosystems have changed over the past century is difficult, as is attributing change to natural cycles versus anthropogenic disturbances.

Specifically, the study found that» [d] uring much of last year's hurricane season, sea - surface temperatures across the tropical Atlantic between 10 and 20 degrees north... were a record 1.7 degrees F above the 1901 - 1970 average,» «global warming explained about 0.8 degrees F of this rise,» while» [a] ftereffects from the 2004 - 05 El Nino accounted for about 0.4 degrees F,» and a natural cycle in sea - surface temperatures «explained less than 0.2 degrees F of the rise.»
