Are we entering an ice age? Maybe CO2 isn't that bad?

Question

David Archibald has an interesting take on AGW. He thinks that the next solar cycle (#24) will be weaker than normal, resulting in reduced solar wind and greater gamma radiation.

This is a theory I've heard before, the gamma rays from other stars interact with water vapor in the atmosphere causing low level cloudiness that blocks solar radiation and causes cooling.

He appears to be presenting this at the Int'l Conference on Climate Change, the one sponsored by the Heartland Institute. I find his choices of rural US data sets a bit suspect (all in the SE) and NASA had predicted #24 to be bigger than normal, and #25 to be small.

Still, given the unusually cold winter both north and south hempispheres have experienced this year, I wonder how far-fetched this is and whether his paper will stand up to scrutiny. What do you think?

Answer 1

the ice is all melting due to global warming, and this is something different i am hearing about.

Answer 2

There is no relation between co2 and temperatures.

CO2 is currently at a historic high, yet globally, this is the 70th warmest, or 60th coldest winter ever recorded.

It's the Sun, not man that causes all warming on Earth.

Answer 3

From what i have heard these few years we are long over due for an ice age. and co2 isnt bad, its vital. but too much is bad.

Answer 4

The planet has been cooling down for the last 5000 years and we should enter the next ice age in a few thousand years.

But CO2 emissins may slow down this process.

Answer 5

Isn't all the ice melting ?
