Not exact matches

I don't think anyone denies that the sun matters for climate, but the question is whether the variability of the sun in recent history has had the impact that we project from greenhouse gases over the next 100 — and there, I think, a majority of your «AGW» ers» would think the evidence suggests that changes in human forcing will likely be several times (at least) larger than any solar variability we've seen in a thousand years or more.

Human activities over recent generations have artificially raised the concentration of greenhouse gases in the atmosphere and scientists conclude that this is why the planet has warmed in recent history.

Denialists like yourself are eager to «disprove» the «hockey stick» because if recent, and future, warming due to AGW is not unprecedented over human history then one can more plausibly argue that there's nothing to worry about.
