The Effects of the Bray Climate and Solar Cycle

Andy May

By Andy May

Javier has posted three new essays on the Bray climate and solar cycle on Judith Curry’s web site. Part A is here, part B is here and Part C is here. In these posts, he lays out the evidence, in some detail, for the climate cycle and the associated solar cycle. Here I will summarize the results of his analysis and explain why it matters. The Bray solar and climate cycle are arguably the most important climate/solar cycle of the Holocene Epoch.

The Bray cycle is about 2450 years from beginning to end and the Bray Lows, which are the coldest portion of the cycle, are the most important events. The Bray lows are easily seen in glacial advances around the world (Bray, 1968), foraminifera fossil records, archaeological records, and lake sediment records. They are less evident in ice core records from Greenland and Antarctica. Figure 1 shows the Bray Lows of the Holocene as blue bars, labeled B5 to B1.
