Finally, it is true that having no children also increases the risk of breast cancer, for two likely reasons: (1) The breasts never receive the benefit of a full - term pregnancy, which renders the breast tissue more mature and thus less susceptible to cancerous change; (2) The breasts are chronically stimulated with more cyclic surges of estradiol, without interruption by periods of pregnancy and lactation.

Irregular / heavy menstrual bleeding can be treated in several ways: 1) Hormonal medication (a low dose birth control pill or cyclic progestin); 2) A hormone - containing intrauterine device (the most common one used is the Mirena IUD, which manages bleeding very effectively and is placed during an office visit and lasts for 5 years); 3) Endometrial ablation is a surgery commonly performed as an outpatient procedure; the entire lining of the uterus is cauterized (many women never get a menstrual period after an ablation); 4) Finally, I reserve hysterectomy as the treatment of last resort — typically only when the above options have not worked for a patient.

While Milankovitch forcing predicts that cyclic changes in the Earth's orbital parameters can be expressed in the glaciation record, additional explanations are necessary to explain which cycles are observed to be most important in the timing of glacial — interglacial periods.

To solve this problem I looked at three patterns of the 6558 day period, overlaid them at the daily weather data level, and plotted the resultant combined signal for Precipitation, and temperature patterns for the USA, extended that cyclic interpenetration for a six year period, and plotted out maps to show the repeating reoccurring patterns in the global circulation, as a (6 year long stretch, we are now ~ 40 months into the posted 6 years long) forecast for part of the current repeat of the 6558 day long cycle.

The answer is, that the growth and decay of ice shows cyclic influences with the same periods as astronomical cycles.

If periods of horrific volcanic activity and horrendous meteor strikes barely budged global temperature from its cyclic course of transitions between Ice Ages and Warm Periods, man's puny efforts are surely lost in theperiods of horrific volcanic activity and horrendous meteor strikes barely budged global temperature from its cyclic course of transitions between Ice Ages and Warm Periods, man's puny efforts are surely lost in thePeriods, man's puny efforts are surely lost in the noise.

Few people have read paleo - climatology text books, are aware of the glacial / interglacial cycle, are aware that the paleoclimatic record has unequivocal evidence of cyclic gradual changes and cyclic abrupt climate events, are aware that the abrupt climate change events such as the abrupt termination of the last 22 interglacial periods lacks an explanation, are aware that all of the past interglacial periods are short (roughly 12,000 years) and that they have ended abruptly, and so on.

Researchers say this back - from - the - dead trick has implications for how ecosystems recover from the planet's cyclic long periods of ice coverage.

There is also ample evidence to show the warming is not linear as they try to show but cyclic — with periods wher the warming has either stalled or reversed.

The question is not if but how the solar serial climate changer causes the cyclic gradual (mediavel warm period and the little ice age) and abrupt climate change (abrupt termination of the last 22 interglacial periods.

In the derivative the NNLS algorithm converges to a much shorter, incompatible period circa 120y, this indicates that the longer cycle was a fortuitous fit to a non cyclic variation and probably does not reflect a true cycle in the data.

While there may well be differences in the regional character of the arctic warming of the early 20th century, and the arctic warming of the late 20th century, I don't think that Dr. Meier really answered Mr. Goddard's question about the possibility of a cyclic pattern in both warming periods.

The amplitude of the cyclic component varies with the trend period.

«All 18 periods of significant climate changes found during the last 7,500 years were entirely caused by corresponding quasi-bicentennial variations of [total solar irradiance] together with the subsequent feedback effects, which always control and totally determine cyclic mechanism of climatic changes from global warming to Little Ice Age.»

These cyclic changes, brought about by the changing gravitational pull of the other planets and the Moon, introduce periods of about 19, 23, 41, and 100 thousand years in the distribution of sunlight over the globe.

There is also no hypothetical basis to presume that, even if it's a zero sum game, that there aren't cyclic trends with periods lasting centuries required to zero it.
