The issue is that there are many sources of uncertainty of nuclear winter. When I developed a probabilistic model taking all these sources into account, I did get a median impact that was 2-3 C reduction (though I was also giving significant probability weight to industrial and counterforce strikes). However, I still got a ~20% probability of collapse of agriculture.
