The numbers look small, don't they? 0.04%? How could anything that small be a big deal? Well, there are people out there who know exactly how much CO2 is too much, and they are explaining to you that despite the small number, it's a lot, and it's going to cause problems. You should listen to them. I don't think 'but it's a small number' is a very good scientific rebuttal.
What do you mean? Have you really not been following the debate over the last 20 years or so? I didn't just make this up. You cannot discredit it as 'junk science' without knowing exactly why you think the science is wrong - and for that, you need to have learned about the science.
Solar flares aren't the same as actual increasing output. Again - whilst it sounds like a big deal, it's a short term thing that's pretty small, without enough thermal energy to make an impact - that's why it was not mentioned as a climate problem.
I think what is happening here is that you are using your intuition and limited knowledge to refute actual science, whereas it should be the other way round. Intuition is a subjective thing, a feeling, and is hard to separate from emotion. Science is about rigorous experimentation, knowledge, debate, contradiction and eventually consensus. It's ok to start with intuition, but do not finish with it.
