Surface Temperature Variability, Fresno/Yosemite, California

Let’s step back and take a look at “climate change” from a different point of view. Assume you live in Fresno, California. The historical daily temperature variation in that area according to data from the US Historical Climatology Network would look like the plot below. Shown are the daily Average Temperature (red), the daily maximum temperature (blue), and the daily minimum temperature (green). A resident in Fresno has experienced a consistent temperature variability range over the prior 200 years. 

Fresno Temperatures

Such temperature change trends have no relation to carbon dioxide. Climates change. Temperatures change. Precipitation changes.

Of course, we must believe the USHCN temperature data for Fresno is valid and not fabricated as found in Luling, TX (here). In any case, can someone please explain how the above temperature record supports the assertion of how “global warming” affects Fresno, how catestrophic “climate change” has occurred, or that there is any significant role for carbon dioxide.

  1. Your temperature scale on the vertical axis is too compacted to see the changes in average temperature, which are measured in single digits. However changes in that range have very significant effects. You are not going to jump from 100 degree to 150 degree maximums. Also, the effects are climate change are accelerating. Even on your chart, you can see the up trend in the last decade. If you want visible proof look at the nearly non-existent snow pack during the drought, compared to previous droughts, and look at the melting glaciers around the world.

    • It looks like you’ve missed the point of the post. The climate is always changing, has been, and always will. The claims made regarding the significance of an up trend in any of the “indicators” are arbitrary.
