Wind Turbines Cause Climate Change

[Crick]

So what caused the ice ages and subsequent warming before man was around?

Milankovitch cycles and very large volcanic eruptions, like the Deccan Traps. The Milankovitch cycles are patterns in the Earth's orbit: axial precession, ellipticity and obliquity that can cause up to 25% changes in the solar energy absorbed by the Earth. Initial warming is reinforced by CO2 released from the Earth's oceans as the planet begins to warm. The Deccan Traps was a massive fissure eruption that lasted approximately 30,000 years and covered an area half the size of the Indian continent in lava 6,600 feet thick. They are the largest volcanic feature on the planet. Most volcanic eruptions aren't large enough to affect global climate, particularly as seen from millions of years down the line.
