- Is the world warming?
- Is that warming due to man’s CO2?
- Will future man-made warming be substantial?
- Will we see catastrophic effects from warming?
- Do CO2 abatement laws like AB32 [California's CO2 cap and trade mandate] make sense?
BTW, I renew recommending Roy Spencer's paper on the Pacific Decadal Oscillation, available here.
