University of Southampton (via Science Daily) (archived copy that may be more readable) reports on work published in Nature Communications (open access; doi:10.1038/ncomms14845). Scientists combined previously published data regarding atmospheric carbon dioxide over the past ~420 million years with an estimate of solar irradiance based on previous work. One of the authors told the University of Southampton:

Our new CO2 compilation appears on average to have gradually declined over time by about 3-4 ppm per million years. This may not sound like much, but it is actually just about enough to cancel out the warming effect caused by the sun brightening through time, so in the long-term it appears the net effect of both was pretty much constant on average.
