You keep citing this and it's probably because you think "Oh, it's just a couple of degrees--no big deal." But that's not how science works.
A 2 degree Celsius (3.6 degree Fahrenheit) rise in global temperatures above pre-industrial levels is considered a critical threshold that could lead to dangerous and cascading effects of climate change. This warming would shift the distribution of daily temperatures to higher temperatures, making extreme temperatures more common. For example, at 1.5 degrees of warming, there would be up to 19 extra days of extreme heat per year on average, while at 2 degrees of warming, there would be around 29 additional days.
