Think of Global Warming or Climate Crisis. The idea is that the average temperature around the world is slowly rising due to human activity. Scientists and all the world except the USA use Celsius (C) as the temperature scale. USA businesses do not want to spend money to change their printed materials, so they lobby to stick with Fahrenheit.

One degree Celsius is 1.8 times larger than one degree Fahrenheit. Those who talk about Global Warming should keep this little table in mind when you are around luddites.
