not a lot Of debate there has been some warming over the last 150 years or so, the real question is, is it catastrophic. The models routinely over forecast temperatures. The median model output from IPCC report AR15 show increases that are double that shown by thermometer record over the last 40 years and three times the satellite record. The difference between the satellite and ground based thermometer records is largely accounted for by the thermal heat island effect that is not adequately corrected for.
the median model forecast has an ECS of about 3.2 (similar to Hansens business as usual forecast), meaning 3.2deg C increase in world temperatures per doubling of CO2 levels. The IPCC likes to emphasise the more extreme scenario of 8.5 ECS, but reality is not much more than somewhere between 1 and 2. That being the case there is no climate emergency.
We currently appear to be heading into a grand solar minimum (GSM). which will hopefully bring realism back into the conversation over the next 10 or twenty years as temperatures drop across Northern Europe, America and Russia/China as happened in the last GSM around 1800. A repeat of the French Revolution perhaps, resulting from cold temperatures and crop failures.
