What Is the Greenhouse Effect?

The figure of 280 ppm for CO2 at the beginning of the industrial revolution was based on samples from ice cores. Ice is not an impermeable material, so gasses can escape, and do, so that figure was far too low. It has since been updated, and is now estimated at around 360 pm.
Therefore the increase since industrial revolution is only around 40 ppm.
This amount is far too small to have any effect on climate whatsoever.
Also the climate warms, the oceans release CO2.
So IF CO2 caused the climate to warm, that in turn would cause the oceans to release more CO2, which in turn would cause more warming, and so on.
This is a positive feedback process, which would cause the global temperature to rise exponentially until the planet baked.
This has not occurred in 600 million years, since the planet emerged from the ''Snowball Earth'' event, even when CO2 levels were 7000 ppm, or 17 times the present tiny 400 ppm, of which human input is a miserable 40 ppm. During that time CO2 and global temperature have varied in opposite directions, for millions of years, contrary to the theory.
Therefore as the observed facts do not support the theory that CO2 causes global warming, the theory is WRONG!
In addition, the level of CO2 and global average temperature, now, and throughout this interglacial period, is the lowest since the Permian extinction, 270 million years ago.
Also, the planet has been in an ever deepening Ice Age for around 40 million years, so the chance of a mythical, ''runaway greenhouse'' effect is ZERO! This ice age is not to be confused with the Malenkovitch cycle of approximately 90,000 years glacial, followed by 10,000 years interglacial period which the planet is in now, and is due to end in the near future.
