Is the Current Global Warming a Natural Cycle?

[cancel2 2022]

We were delighted to see the paper published in Nature magazine online (August 22, 2012 issue) reporting past climate warming events in the Antarctic similar in amplitude and warming rate to the present global warming signal. The paper, entitled “Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history” and authored by Robert Mulvaney and colleagues of the British Antarctic Survey (Nature, 2012, doi:10.1038/nature11391), reports two recent natural warming cycles, one around 1500 AD and another around 400 AD, measured from isotope (deuterium) concentrations in ice cores bored adjacent to recent breaks in the ice shelf in northeast Antarctica.

Global warming? Isn't that a left wing fable?

Natural?? Meaning a logical result from loading the atmosphere with greenhouse gasses?

Was the oil spill in the Gulf a natural cycle?

LOL the warmers reject empirical evidence that shows the warming is in fact not unprecedented.

Who did that? Where? When?

Meaning that they have found pre-industrial climate warming events in the Antarctic similar in amplitude and warming rate to the present global warming signal. There are two ways to deal with that, either ignore the evidence and dismiss it as inconsequential or try to explain the findings.
