Question

Which is greater a 1 degree rise in the Celsius scale or a 1 degree rise in the Fahrenheit scale?

Answer 1

The degree in the Celsius scale is larger than the Fahrenheit equivalent. The conversion is Celsius times 1.8 equals Fahrenheit. Thus a one Celsius degree rise in temperature is equivalent to a 1.8 Fahrenheit degree rise. Your 20 Celsius degree temperature difference is in fact 36 Fahrenheit degree difference, not 68.
