Joanne Nova tries to reinforce her idea that the 2013 heatwave is nothing special … by listing just one station’s data (huh?) and by not showing 2013 in her graph. Here’s how the graph would appear with the first 17 days of this year included.
Nothing special – aside from it being the highest average maximum temp (so far). Whilst this picture will change with future data, it’s not possible, from the data, to suggest that the current January heatwave is not unusual. This is not the only problem with Nova’s argument.
