New paper: Influence of solar cycles on climate change during the Maunder Minimum

Next Grand Minimum readers will find this an interesting paper on the Maunder Minimum and the impact of cosmic rays.

Watts Up With That?

Both observational and proxy records of climate change often show quasi periodic variations similar to solar activity cycles over a wide range of time scales. However, the detailed mechanism and the extent of the influence of solar activity on climate change have not been clearly understood. Although the exact role of each of solar parameters on climate change has not been quantitatively clarified, several possible mechanisms are proposed; such as the forcing through total (e.g. Lean et al., 1995) and spectral irradiance (e.g. Haigh 1996; Kodera and Kuroda, 2005), solar wind (e.g. Tinsley, 1996) and the galactic cosmic rays (Friis-Christensen and Svensmark, 1997; Svensmark, 2007). Among these parameters related to solar activity, galactic cosmic rays possess characteristic variations depending on the polarity of solar dipole magnetic filed as shown in Figure 1.

The polarity of solar dipole magnetic field reverses at every maxima of 11-year sunspot activity cycle, and so…

NOAA – 1695 Low Max Records Broken or Tied From Sept 11 to Sept 20. One record broken by 25F

Are we on the cusp of the next grand minimum yet?

sunshine hours

Wow. One record was broken by 25F!!!!

1695 Low Max Records Broken or  Tied From Sept 11 to Sept 20 according to the NOAA.

A “Low Max” means that the maximum temperatures for the day was the lowest it has ever been. This indicates daytime cooling.

Below is a screenshot showing location and the biggest difference between old record and new record.

The list is just the ones I could capture in a screenshot.

Antarctic Sea Ice Extent Sep 19 2014 – 1,535,000 sq km above the 1981-2010 mean. Data for Day 261. Data here.

Another 58,000 sq km. 7th All-Time Record in 7 Days.

610,000 sq km higher than the previous daily record.

Prof Bob Carter warns of unpreparedness for Global Cooling

According to GJR in a comment , a sure sign of the next ice age is wheat killing spring frost. Please note the kill frost that destroyed the spring wheat in Australia.

Watts Up With That?

Eric Worrall writes:

Professor Bob Carter, writing in today’s edition of The Australian, a major Aussie daily newspaper, warns that the world is unprepared for imminent global cooling, because of the obsession of policy makers with global warming.

According to Bob Carter;

Heading for ice age

“GRAHAM Lloyd has reported on the Bureau of Meteorology’s capitulation to scientific criticism that it should publish an accounting of the corrections it makes to temperature records (“Bureau warms to transparency over adjusted records”, 12/9). Corrections which, furthermore, act to reinforce the bureau’s dedication to a prognosis of future dangerous global warming, by turning cooling temperature trends into warming ones — a practice also known to occur in the US, Britain and New Zealand.

Meanwhile, we have a report by Sue Neales that the size of our grain harvest remains in doubt following severe frosts in southern NSW killing large areas of early…
