If by 'rural' you mean --not urban, then you would be right in saying that the urban environment is typically 'hotter' and has been for 2000+ years- but the upward trend is the same and the impact  on agricultural production will be significant.

      I said "'hotter'" not 'temperature'. Different meanings.

      'Hotter' is a concept that has been around for millennia, temperature needed the advent of measuring devices and scales. to

So how do we know the urban environment was hotter?

 That the "...urban environment is typically 'hotter' and has been for 2000+ years- " is as a result of the evolution of urban areas. Increase in population, density of population, building design, construction materials  industrial activity and manufacturing, use of animals, fuel burning, lack of ventilation, reduced effect of transpiration and evaporation in cooling, increasing pollution and temperature inversions, etc.

It was warm today but it was hotter last year.

2000+ years I hadn't realized we'd been able to measure temperatures for that long.

That does look like a misunderstanding, onl;y you know whether it's deliberate or not; we have been able to measure fairly accurately, temperatures for a couple of hundred years, since the invention of the thermometer.
Prior to that, current scientists need to estimate temperatures; i.e. a scientific estimate, not a number pulled out of a hat by someone with no direct training & research experience.
Various methods can be used, coral growths, tree rings, microfossils, ice core samples etc.
The latter are quite interesting as the contents can be analysed for the different ratios of carbon isotopes.
Any cursory glance at the internet will yeild sites such as this

Absolutely, and forecast to be wet tomorrow, but that's local short term weather, not global long term climate.

#So you accept that the earth is hotter?

  In mathematics and statistics use of the word 'significant' means what it says and not in the dilute form used in spoken English.

 The other mistake you make is making the assumption that because a data set is mathematically 'significant' (is that a data beyond chance) is you can then can ascribe valueless words like 'harmful'. 

  It really does not help to advance your case that you go off on your usual political tangent.

 

You are getting to sound a lot like "Old Ma Murphy the strong arm School Marm" from the Dandy, 😀

 

I was talking about climate change.

 

What are you on about?

Not a misquote, that is a direct copy and paste of your last paragraph.

Urban heat sprawl does increase urban air temperatures but we know that because we can measure it, we don't know that happened 2000 years ago because we couldn't measure it, we may be able to surmise that but not know.

   Talking about climate change is not the same as applying statistical techniques to billions of bits of data collected over time.

   Talking about climate change is not the same as understanding it. 

   The use of the term "significant" in statistics means the linkage between the variables is not occurring by chance and can be ascribed a number to or range of certainty. The use of numbers also enables others to check the accuracy of the work done, whether the findings can be repeated and most import does new data support the initial findings.

 

    There is no need for you to worry so much about the left wing media and "... Algore, Kerry, Biden, Greta, et al" as they and their opinions are statistically insignificant, but the evidence for unprecedented change is.
