There have been claims that the Earth is entering period of strong climate cooling; e.g. see
Such predictions of cooling, however, are no more substantiated by skillful validated predictions of this cooling, than are the IPCC predictions of more-or-less uniform global warming.
What the science does tell us is that the human influence on climate is significant and involves a diverse range of first-order climate forcings, including, but not limited to the human input of CO2 (e.g. see). Natural variations are important (and still not yet adequately understood; e.g. see), and the human influence is also significant and involves a diverse range of first-order climate forcings (including, but not limited to the human input of CO2).
To assume we understand enough about natural climate variations and long term trends to skillfully predict a sudden cooling of the global climate is not supported by peer reviewed scientific research. We need to recognize that accurate climate prediction is a much more daunting challenge than is reported in the news article above, and in the 2007 IPCC report.
For summary of the Climate Science perspective on climate, please see my 2007 House testimony.
