The solar sunspot cycle is eleven years, with a delta-irradiance of 0.50%.

What's new in human understanding is the immediate conduit from the Heliosphere to Earth's surface via waves that propagate [from/to?] the Equator.

The comments on Slashdot support you.

It's the rate of change, not the absolute level of temperature, that will stress the environment. A +4C world doesn't look much different if you take 8000 years to get there, but it looks *very different if you've got here in less than a century. Over eight thousands years, even populations of *trees* can migrate hundreds of miles. Doing it in less than a century stresses human societies which are by far the fastest adapting feature of the planet.
