#### Unscramble the Blue Letters

Let's look at the atmosphere. This is a depiction of what we used to think of as the normal distribution of temperatures. The white represents normal temperature days; 1951-1980 are ararritbiyl eohscn. The blue are cooler than average days, the red are warmer than average days. But the ertnei vurce has moved to the right in the 1980s. And you'll see in the lower right-hand corner the appearance of statistically significant numbers of extremely hot days. In the 90s, the curve shifted further. And in the last 10 years, you see the extremely hot days are now more numerous than the cooler than average dasy. In fatc, they are 150 times more onmmco on the surface of the earth than they were just 30 years ago.

#### Open Cloze

Let's look at the atmosphere. This is a depiction of what we used to think of as the normal distribution of temperatures. The white represents normal temperature days; 1951-1980 are **___________** **______**. The blue are cooler than average days, the red are warmer than average days. But the **______** **_____** has moved to the right in the 1980s. And you'll see in the lower right-hand corner the appearance of statistically significant numbers of extremely hot days. In the 90s, the curve shifted further. And in the last 10 years, you see the extremely hot days are now more numerous than the cooler than average **____**. In **____**, they are 150 times more **______** on the surface of the earth than they were just 30 years ago.

#### Original Text

Let's look at the atmosphere. This is a depiction of what we used to think of as the normal distribution of temperatures. The white represents normal temperature days; 1951-1980 are arbitrarily chosen. The blue are cooler than average days, the red are warmer than average days. But the entire curve has moved to the right in the 1980s. And you'll see in the lower right-hand corner the appearance of statistically significant numbers of extremely hot days. In the 90s, the curve shifted further. And in the last 10 years, you see the extremely hot days are now more numerous than the cooler than average days. In fact, they are 150 times more common on the surface of the earth than they were just 30 years ago.
