The sun, not man, has the most to do with climate change

I agree Mike Eckhart—Let’s keep breathing!

Milankovitch (1879-1958) gave voice to the idea that Earth’s long-term climate changes are due to periodic changes in the Earth’s orbit and obliquity (Earth’s axial tilt).

We live in earth’s global heating cycle, which is 10,000-plus years in duration, and we are about 600-plus years from where the heat from the sun to earth will be the greatest. Last December 21, Australia received its maximum heat from the sun from earth’s tilt, and on January 3 its greatest heat from being the closest to the sun.

In 600-plus years the greatest tilt will coincide with the closest approach to the sun for the day of greatest heat transferred in this heating cycle. After this point in the cycle, the heating of the earth will continue but with less heat retained each year, and in a 1,000-plus years the cooling cycle will begin and be observed.

What Milankovitch missed in his theory of global heating and cooling cycles was the secondary effects of the two hemispheres. The Southern Hemisphere’s is composed of 20 percent land mass and 80 percent water mass (oceans), while the Northern Hemisphere’s is 40 percent and 60 percent respectively.

The Mass Heat Capacity of Water is fourtimes greater than land masses. The Southern Hemisphere can store 20 percent more heat than the Northern Hemisphere because of its larger ocean masses; and since the yearly cooling cycle of the earth cannot remove all this heat, the earth’s average temperature is increasing.

YES the Global Heating Cycle is real. AND NO, industrialization and burning fossil fuel, and other human activities are not a significant factor for these cycles. The increase in CO2 is part of this natural cycle. The ice-core samples from earth’s two poles shows that the increases of trapped CO2 gasses correspond to the Global Heating Cycle.

Milankovitch was right; the 100,000 years icecores show minimum CO2 concentrations, which corresponds to earth’s lowest temperatures, and Global Cooling Cycle will cover Minnesota with ice and snow the year round!
