Figure 1

The Exxon Sea-level Curve with E, H and W solar phase boundaries (see Figure 4). W-peaks are warm period maximums from the intense irradiance of an active Sun, where E-points and H-points are the beginning and end boundaries for the passive phases of the Sun. H-phases relate to glacial periods and lowstands in Phanerozoic sea levels, whereas W-phases relate to high sea surface temperatures and highstands in sea level.
