The arguments shift, a few years back there was very widespread denial that the climate was changing. Following repeated record years now there is a reasonable consensus that the climate is changing (up to about 60% of conservatives in the US and UK), and people now seem to think this acceptance was always there. The next argument as you say is whether it is manmade, after that it will be about whether it is serious enough to need tackling, or about whether it's so serious that nothing can be done. Underlying this is the basic worry to avoid damaging quality of life (which is a perfectly reasonable concern) and the ideological motivation to avoid intervening in the economy. Beyond the motivated reasoning there is also the actual scientific argument about whether the climate sensitivity is 1C, or 2.5C, and whether therefore we should be taking moderate action or severe action. There's not much of a scientific debate about whether we should be doing nothing at all. Ironically in the Anglosphere there is a consensus for moderate action amongst the public, including the conservative public, but the political elites haven't yet caught up.
