The IPCC assessment reports[1] are really well researched and comprehensive reports of the current science, including measures of confidence in plain language. They aren't hard to read, and there's any number of summaries available, including on Wikipedia[2]. It's a great place to start (and, for most non-climate-scientists, end) your research.
If you (general 'you', not you specifically, parent) want to dismiss an aggregate report of almost all climate scientists across the planet who research this stuff day in and day out as political theater, then I suggest your view of reality may be skewed by some other factor. Science provides us with data as near to facts as it's possible to get; it's up to us how to interpret those facts.
