global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature.

The average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880; Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20 °C per decade.
