Please read more, Senator Fielding

Steve Fielding has returned from Washington and he says that he has some questions for the government:

“I heard views which challenged the Rudd government’s set of ‘facts'”

And one of these is on solar activity and the influence on climate change.

“The idea that climate change is a result of the variation in solar activity and not related to the increase of CO2 into the atmosphere is not something that I can remember ever being discussed in the media.”

You think that he might actually read some of the material itself. Does he only get his information from the media? Let’s look at some of the published literature.

The IPCC discussed the influence of solar activity in 1992, 1994, 2001 and 2007. For example, from the 2007 Summary for Policymakers we have:

During the past 50 years, the sum of solar and volcanic forcings would likely have produced cooling.

The summary then goes on to discuss how solar and volcanic activity was used in the models.

Our own CSIRO has produced a pamphlet titled “The science of climate change” which says:

Natural variability such as the El Nino cycle and variations in solar activity can affect the temperature, while large volcanic eruptions can lead to cooling.

These are just a couple of references to solar that I have found. Maybe the senator should do a little more reading of the science, and not just the media reports.

Here is a video that covers some of the facts on solar activity and climate change.
