Walter Williams compiles data from many years to show the climate isn't warming as the alarmists say it is.
Hot weather is often claimed to be a result of man-made climate change. Heller presents data showing the number of days in Waverly, Ohio, above 90 degrees. In 1895, there were 73 days above 90 degrees. In 1936, there were 82 days above 90 degrees. Since the 1930s, there has been a downward trend in the number of days above 90 degrees. If climatologists hide data from earlier years and started at 1955, they show an increase in the number of above 90-degree days from eight or nine to 30 or 40. Thus, to deceive us into thinking the climate is getting hotter, environmentalists have selected a starting date that fits their agenda.
