Sentences with phrase «forced by some cosmic ray»

Not exact matches

Although the pentaquark's life span is rather long by subatomic standards (10 - 20 seconds), it's so unstable that it can be created only by high - energy cosmic rays striking Earth's atmosphere or by the forces at work within the center of a neutron star.

Even if the cosmic ray theory is borne out by evidence, where is the room for it to be anything more than another, and not very significant, forcing factor?

On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on feedbacks, since I don't see a contradiction between an internal radiative forcing and positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray hypothesis.

Perhaps if gun industry spokespeople had a history of claiming their products can't cause harm, or that what appear to be bullet holes in people are actually caused by cosmic rays, sunspots, volcanoes, internal forcing, or other natural phenomena, the courts might rule differently.

Even if the cosmic ray theory is borne out by evidence, where is the room for it to be anything more than another, and not very significant, forcing factor?

I always believed that the oceans were an important element in localised weather conditions over the short term but feel that relatively sudden shifts in climate occur through external forcings such as volcanic eruptions, meteor strike and the effects of changes in cosmic rays and sun spot activity, which are, unfortunately, all chaotic by nature and unpredictable.

(e.g., by omitting / underestimating major cooling methods like thunderstorms / hurricanes or external forcing like cosmic rays / clouds) See also numerous discussions of uncertainty at Climate Etc..

2) Warm or cold is irrelevant because it was during a transition between two quasi-stable climate regimes (glacial: interglacial) where all forcings (including Milankovitch and cosmic rays) were made irrelevant by strong positive albedo feedback.

[1] AR4 Chapter 2: Changes in Atmospheric Constituents and in Radiative Forcing 2.7.1.3 Indirect Effects of Solar Variability «Various scenarios have been proposed whereby solar - induced galactic cosmic ray fluctuations might influence climate (as surveyed by Gray et al., 2005).»

The strength of the magnetosphere is regulated by the sun (whose activity changes in synchrony with the planets), but perhaps the strength of the Earth's magnetosphere is also regulated directly by the gravitational / magnetic forces of Jupiter and Saturn and the other planets whose gravitational / magnetic tides may stretch or compress the Earth's magnetosphere in some way making it easier or more difficult for the Earth's magnetosphere to deviate the cosmic ray.

He ignores the possibility that decadal variability may be caused by external forcing such as cosmic rays which are known to cause increased rates of aerosol nucleation.
