Quote:
Until the Industrial Revolution, melting of snow and ice at the end of cyclical glacial periods was driven by changes in the Earth’s orbit. As snow and ice melted on the planet, the albedo, or reflectivity, of the earth declined, with land and ocean absorbing more heat from the sun (think the reflectivity of cars in a parking lot versus the hot blacktop of the parking lot itself). As the planet slowly warmed, a warmer and better-mixed ocean released CO2 into the atmosphere, which amplified the warming that was already in progress. In all, temperature typically increased by 6°C (11° F) over thousands of years during these interglacial periods, and one third of this increase was a result of the CO2 that outgassed from the ocean once warming began. Therefore, CO2 was not the initial cause of melting ice on the planet. It merely amplified a signal that was already in progress.

By contrast, as humans burn fossil fuels, we are creating a new driver of snow and ice melt and accompanying sea-level rise. This time, additional CO2 entering the atmosphere is coming from sources of carbon that had previously been sequestered in fuels such as oil and gas. We know from basic physics that CO2 traps heat. The phenomenon is perhaps best demonstrated by Earth’s neighbor Venus. If we lived on Venus, the computer you’re reading this post on now would be melting. That’s because Venus has 100,000 times the amount of CO2 in its atmosphere as Earth does and its average temperature of 462° C (863° F) is high enough to melt lead.

It seems warming has a loooooooooooooooooonnnnnnnnnnnnnnnnnnnngggggggggggggggg way to go yet!

Who cares.

Increasing CO2 in the atmosphere is going to keep heating the earth!

Nah.

There is another greenhouse gas to be considered. As the globe heats up there is more water vapor in the air. Water vapor is a GHG, another positive feedback loop.
