Recent data and research supports the importance of natural climate variability and calls into question the conclusion that humans are the dominant cause of recent climate change. This includes

  • The slow down in global warming since 1998
  • Reduced estimates of the sensitivity of climate to carbon dioxide
  • Climate models that are predicting much more warming than has been observed so far in the 21st century

While there are substantial uncertainties in our understanding of climate change, it is clear that humans are influencing climate in the direction of warming. However this simple truth is essentially meaningless in itself in terms of alarm, and does not mandate a particular policy response.

We have made some questionable choices in defining the problem of climate change and its solution…
