Sentences with phrase «solar magnetic»

Why are correlations of Earth's temperature with natural factors such as sunspot numbers, solar cycle lengths, solar magnetic variations and changes in major ocean currents all better than the correlation of Earth's temperature with CO2 levels?

So if solar magnetic field were to increase, fewer GCRs would reach Earth, seeding fewer low - level clouds, which are strongly reflective.

In the almost sure knowledge that the earth never experienced a runaway greenhouse even with ancient CO2 levels 10 to 20 times greater than today, these anti-science scoundrels insist with a «high level of confidence» that this amplification is real and it's based on nothing more than faster than expected surface temperature rise in the past few decades which can be TOTALLY explained by multi-decadal cyclic behavior in ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changes.

The author, Michael Asher, noted that «The event is significant as many climatologists now believe solar magnetic activity - which determines the number of sunspots - is an influencing factor for climate on Earth.»

So if there are fewer GCRs reaching Earth (because a strong solar magnetic field is deflecting them away), the hypothesis says there will be fewer clouds, more sunlight reaching the Earth's surface, and thus more global warming.

GCRs are modulated by both solar magnetic field, which is largely unpredictable in strength except for generalities associated with 11 - year sunspot cycle and is also modulated by unpredictable events like nearby supernovas, and by more predictable very very long slow changes in intensity due to the solar system traversing spiral arms of our galaxy and wandering above and below the galactic plane in cycles lasting tens and hundreds of millions of years.

The theory goes that the solar magnetic field deflects GCRs, which are capable of seeding cloud formation on Earth.

That's impressive evidence that solar magnetic activity has some profound unexpected influences on the earth.

Note that according to Leif's latest graph, the solar magnetic field strengths have been increasing, since 2015 (when the cosmic ray measurements also began)

This pattern derives from the fact that the cosmic ray flux record, which is inversely proportional to solar magnetic activity, presents a slight decrease from about 1970 to 2000 (Scafetta 2013c, Fig. 20).

If GCR flux is modulated by solar magnetic variability then how do we account for the rise in OHC since around 1970?

As seen in Figure 6, particularly the higher - frequency variations in the two radionuclide estimates agree rather well in phase and show higher amplitudes than the geomagnetic reconstructions, confirming the results by Snowball et al. (2007) that variations in radionuclide production rates on up to multi-centennial time scales are dominated by solar magnetic field variations.

An alternative recorder for past geomagnetic field changes are cosmogenic radionuclide production rates, which are modulated by variations of both the solar magnetic field strength and the geomagnetic field intensity.

Unlike the great sporadic storms, moderate geomagnetic activity does not exhibit a well defined connection with sunspots or any other indicator of solar magnetic activity.

The changes in the solar magnetic field impacting the Earth at polar regions cause changes in surface pressure.

23 out 23 times, the planet cooled when the solar magnetic cycle changed from a grand maximum to a Maunder like minimum.

However, beware of the future because the oceans are hiding the enormous cooling as cloud area increases because of low solar magnetic field.

Hale suggested that the sunspot cycle period is 22 years, covering two polar reversals of the solar magnetic dipole field... The start of the 22 - year cycle begins... This process of sunspot formation and migration continues until the solar dipole field reverses (after about 11 years).
