General Discussion

On top of a statistically fit non-linear curve of 20 years of daily temperature maximums, a couple of weeks is just not going to have much leverage to bend the curve. For France, it would undoubtedly clearly show climate change to a person able to appreciate the analysis.

If you arbitrarily shorten the reporting time-frame, which minimizes the leverage of old data, and maximizes that of recent data, there will be a bigger impact on the curve-fitting

But Climatologists do have rules that constrain researchers to publishing based on "best" methods, and looking at a week as significant to climate is not a best method.

When it's done correctly, the data show climate change, but it's done using the same methods across much more than 100 years of data

The balance of gases, and the presence of certain microorganisms in ice-samples takes us back tens of thousands of years. Against that mass of data, 2 weeks of hot weather, even record hot weather hardly shows up as a blip
