[ RadSafe ] OT: Global Warming

Interesting - but, again, not all that meaningful from the perspective of really understanding what's happening with climate due to the brevity of the time span in question. To use a radiological analogy - how accurately can you characterize an environmental sample with only a few Bq of activity with 1 minute of counting time?

According to numerous sources there has not been any global warming for approximately 18 yrs.
