What is your evidence that the Sun’s output has increased substantially enough to account for the current warming trend? The IPCC covers this in their Fourth Assessment Report. The fact is the sun’s output has not changed significantly in the last 30 years. However, CO2 output from the burning of fossil fuels (and the change in land use) has changed significantly. The amount of CO2 in the atmosphere was relatively constant from AD 800 until the late 1800s, at a level of 280 parts per million. In the last century it has shot up to 380 parts per million – an increase of 36%.

But the current flat line period shows that, despite Man continuing to put out CO2 and methane, nature does what nature wants.

Nobody who accepts the evidence for AGW disputes that nature affects the climate. For example we had an unusually warm year in 1998 due to an unprecedented el Niño not because the Sun increased it’s output substantially that year. For all your arguments about natural processes primarily driving global warming you don’t even seem to understand that very well.

But the current flat line period shows that, despite Man continuing to put out CO2 and methane, nature does what nature wants.

But according to you global warming stopped in 1998. Of course by that definition global warming has stopped several times since the Little Ice Age (and then started again). So which is it, Teach?

As for the planes, they still put out lots of CO2. Or, are you saying do as I say not as I do is OK?
