Tinus Pulles critique of our paper begins by admitting that, at present there are no adverse effects from climate change, but that we ignored possible future climate change effects. This was deliberate, as we wanted to deal only with established and observed facts and data. Climate model projections of the effects of climate change are highly speculative because the climate change models they use as input are incorrect and project too much warming as documented in the paper and in AR6 (McKitrick & Christy, 2018), (McKitrick & Christy, 2020), and (IPCC, 2021). I do not think there is any need to respond to projections from the critique. //

Pulles acknowledges that AR6 shows that present levels of global warming are moderate, but claims experts project that that will not be the case in the future. The IPCC’s AR6 admits that their models run too hot, and that the AR6 models are worse relative to observations than the AR5 (2013) models were. Their models are getting worse with time, so their projections should not be believed. When new versions of a model get worse, it is a sure sign that the premises the models are based upon are wrong (see here and here). //

I see nothing in this critique that invalidates anything in our paper, but feel free to read Pulles comments and decide for yourself.
