CLIMATE CHANGE

Everyone has opinions about climate change, but what does the data show. I selected Alvin, Texas in Brazoria County. South of Houston, outside of the metro area, I thought this would be more representative and not affected by city heating. There are weather stations with temperature data going back to 1901 in Brazoria County, so the data was pulled together and the number of days with maximum temperatures equal or greater than 95 degrees was counted (dashed orange line), then a rolling 7 year average was calculated (red line). The gray line is the average solar energy for the year, which is about ~1300 W/m2 with some very slight variance (+/- 2 W/m2). Which doesn't account for the temperature increase. 
However, when oil consumption is added to the chart (black line) it shows that oil consumption in 1950 was ~6 million barrels/day and has grown to almost 20 million barrels per day in 2020. Each barrel is 5.8 million BTUs of heat energy, so increased burning of oil has caused Brazoria County to begin to experience much more 95+ degree days.
