<\/div>\n
Skipped Beats of Earths Climate – The past and future of glacial cycles..<\/div>\n
<\/div>\n
\n
Over the last 2 million years, Earth’s climate has periodically cycled between warm and cold states –<\/div>\n
the so-called glacial and interglacial climates. We are currently in an interglacial phase that began<\/div>\n
about 11,000 years ago. During the glacial states, ice sheets covered large areas of the northern<\/div>\n
hemisphere land mass and consequently sea levels were lower than today. The shift between these<\/div>\n
climate states is very likely driven by periodic oscillations in Earth’s axial tilt which cycles<\/div>\n
approximately 41,000 years. For the first one million years of the glacial cycles, they recurred with<\/div>\n
the same period. However, the latter half saw the glacial cycles occurring in intervals of 80k and<\/div>\n
120k years, i.e., 2x or 3x the period of axial variations. In this talk, I’ll present a working hypothesis<\/div>\n
to explain the skipped beats of glacial cycles and a prognosis for the future climate state of Earth.<\/div>\n<\/div>\n
