From the Ted Talk by R. Saravanan: Is the weather actually becoming more extreme?

Unscramble the Blue Letters

Most boundary conditions have well-defined values that change slowly, if at all. This allows researchers to reliably prdeict climate years into the future. But here’s where it gets tricky. Even the slightest change in these boundary conditions represents a much larger shift for the chaotic weheatr sysetm. For example, Earth’s surface temperature has warmed by almost 1 degree Celsius over the last 150 years. This might seem like a minor sfhit, but this 1-degree cahgne has added the energy equivalent of roughly one miollin nuclear warheads into the atmosphere. This massive surge of energy has already led to a dramatic increase in the nbeumr of heatwaves, droughts, and storm surges.

This massive surge of energy has already led to a dramatic increase in the number of heatwaves, droughts, and storm surges.
