Milankovitch Cycles and Glaciation
The episodic nature of the Earth’s glacial and interglacial periods within the present Ice Age (the last couple of million years) have been caused primarily by cyclical changes in the Earth’s circumnavigation of the Sun. Variations in the Earth’s eccentricity, axial tilt, and precession comprise the three dominant cycles, collectively known as the Milankovitch Cycles for Milutin Milankovitch, the Serbian astronomer and mathematician who is generally credited with calculating their magnitude. Taken in unison, variations in these three cycles creates alterations in the seasonality of solar radiation reaching the Earth’s surface. These times of increased or decreased solar radiation directly influence the Earth’s climate system, thus impacting the advance and retreat of Earth’s glaciers.
It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables is not due to the total amount of solar energy reaching Earth. The three Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.

Conversation with Global Warming skeptic Anthony Watts a Meteorologist
Spencer Michels interviews one of the nations’s most read climate skeptics Anthony Watts a Meteorologist. Watts believes much of the data used to support global warming theories is faulty. The big problem, as Watts sees it, is that the station were temperatures 🌡️ are gathered are too close to urban developments where heat is soaked up and distorts the reading. So it looks like the earth is warming thought it may not be.
Thomas Sowell: Global Warming Manufactured by Intellectuals?
“It is difficult to get a men to understand something, when his salary depends on his not understanding it.” – Upton Sinclair
“Every great cause begins as a movement, becomes a business, and eventually degenerates into a racket.” – Eric Hoffer, The Temper of Our Time
“You can’t say A causes B if B happens first” – Thomas Sowell
Author Thomas Sowell argues that public demand for intellectuals is largely manufactured by intellectuals themselves. He says intellectuals make alarming predictions using causes like global warming to create a needs for their services.
John Christy on making sense of data in the climate change debate
Climate 🔭 scientist Dr. Michael Mann notes climatologist Dr. John R. Christy as a compelling voice on the other side of the climate change debate. Dr. Christy, a pioneer in measuring global temperatures by satellite, 🛰️📡 discusses challenges to understanding data from satellites, balloons, and terrestrial weather stations. He also examines the impact of CO2 and the practical problem with climate models driving energy policy worldwide, especially in developing nations.
Distinguished professor of Atmospheric Science and director of the Earth System Science Center at The University of Alabama in Huntsville, as well as the Alabama State climatologist, Dr. Christy talks with Dr. Jed Macosko, academic director of academicinfluence.com and professor of physics at Wake Forest University.
