Breaking weather records from a century ago only shows that it was hotter before CO2 emissions began

I am off again on an assignment for a few days and blogging will be light.

It’s summer and where I’m going torrential rain or blistering sunshine with temperatures over 45 °C  are quite normal for this time of year. If it is raining the temperature may be down to 25°C. So I’m prepared for a possible variation of some 20 deg C. It’s just weather.

I note the usual summer stories from around the world of heat waves in some places and “coldest” Junes in a 100 years in others. Some farmers are complaining about droughts and others are complaining about floods. Where societies have ignored repairs or have not built up their infrastructure to match the changing concentrations of urban populations – disasters occur. But I also note that when parts of the US declares that they have just had the hottest period for 50 years or 100 years or whatever and that this is “proof” of global warming they conveniently forget that 50 years ago or 100 years ago or whenever, man-made emissions of carbon dioxide were orders of magnitude lower. When weather records from a hundred years ago are broken it only proves that it was hotter/colder/stormier/wetter/drier or whatever long before the modern industrial age and before any significant man man-made carbon dioxide emissions.  Breaking an old record only shows cyclic behaviour – not “runaway” behaviour!

It’s summer and people are on vacation and journalists are looking for stories and the silly season has begun!
