Weekly Climate And Energy News Roundup

 In "Empirical assessment of the role of the Sun in climate change using balanced multi-proxy solar records" published by Geoscience Frontiers, Nicola Scafetta takes exception to the publications of the UN Intergovernmental Panel on Climate Change which give the sun an extremely minor role in causing climate and temperature changes.

"The result also suggests that at least about 80% of the solar influence on the climate may not be induced by TSI forcing alone, but rather by other Sun-climate processes, which must be thoroughly investigated and physically understood before trustworthy GCMs can be created. This result explains why empirical studies often found that the solar contribution to climate changes throughout the Holocene has been significant, whereas GCM-based studies, which only adopt radiative forcings, suggest that the Sun plays a relatively modest role. Appendix A includes the proposed TSA records."

Thus, the Svensmark Hypothesis advanced by Henrik Svensmark and Eigil Friis-Christensen linking high energy cosmic waves with changing intensity of solar wind may be a possible explanation for the current abrupt warming.

To explore the possibility of solar activity reducing cloudiness, resulting in warming further, one needs to check on changing solar activity.

An active Sun was expected, and these events are indications that the current Solar Cycle 25 is reaching its peak in activity, known as Solar Maximum.

The Sun's polar field reversal is the major hallmark event that signals the end of a solar cycle's Maximum period and ushers in the transition to Minimum.

The newly established polar field will determine the strength of the next solar cycle.

Solar Cycle 24's north polar field took nearly five years to reverse!

The NSO operates the NSF's six ground-based solar telescopes that make up the GONG suite of ground-based solar telescopes.

"While the solar poles will 'flip', rest assured, there's no need for us to flip out. This is a naturally occurring process on a massive scale that's happened throughout the Sun's lifetime. A polar field reversal would indicate a healthy solar cycle and that things will continue as it was in the past, whereas a lack of a reversal would indicate potential major changes to the solar cycle. As we anticipate the polar field reversal, we can expect to see a larger number of X-class flares, larger CMEs, and stronger geomagnetic storms - stay tuned for the next update!".
