There are various cycles worth investigating in oceans and the atmosphere as well as changes in magnetic fields. Incoming cosmic rays occasionally play a role.
It is amazing that individuals, above average in intelligence and education, who display a basic understanding of many factors related to earth's temperature including climatic changes over time and weather changes over shorter time periods become swept away in hysteria generated by climate alarmist. Their models do a poor job of predicting historic data.

The climate models that project greater amounts of warming this century are the ones that best align with observations of the current climate, according to a new paper from Carnegie's Patrick Brown and Ken Caldeira published by*Nature. Their findings suggest that the models used by the Intergovernmental Panel on Climate Change, on average, may be underestimating future warming.

There are a number of bad models, but there are a number of spectacularly good models, which is why our ability to predict hurricanes strength and location has become so accurate. What we have seen is that for the most part the models have been low balling the speed with which these changes are taking place and that may reflect the political pressure to do so.
Predicting weather uses much of the same factors that predicting climate does, so the improvement in our ability to predict weather is evidence of how good this science is. The issue is data, the more high quality data, the better. Second issue is having a computer powerful enough to handle all the data. This is one of the primary applications for these bigger and more powerful super computers you see rolling out every couple of years.
