I'm sure there are natural forcings that play a factor in climate change.
Impossible. The UN/IPCC and Suzuki said as much... And they peer review everything
man, all man and nothing but man.
When? This ice age? We are still in an ice age you know.Being in an 'interglacial period' isn't a forcing. Some interglacial periods have lasted over 100,000 year
The interglacial period started 13000 years ago without a single person using gasoline, coal or NG.The general scientific consensus is that carbon emissions are currently the predominant factor in warming the Earth. This is in the context of all forcings, natural or anthropogenic, warming or cooling.
The interglacial period started 13000 years ago without a single person using gasoline, coal or NG.
And CO2 has gone up and down during the Holocene Climate OPTIMUM.
Why is it called an optimum?
Many studies have produced evidence that the two strongest orbital cycles (obliquity, 41 kyr and precession, 26 kyr) probably do drive changes in ice volume. The data in the figure have been fitted to these periods and also to the longer, much weaker 100 kyr eccentricity cycle. Over the past ~1 million years there have been a number of very strong glacial maxima and minima, spaced by 80,000 - 120,000 years, but the evidence for orbital forcing of these events is less secure. It is likely that this ~100 kyr cycle is controlled by some other as yet unknown mechanism
