#### Unscramble the Blue Letters

Last year I showed these two slides so that demonstrate that the cicart ice cap, which for most of the last three million years has been the size of the lower 48 states, has shrunk by 40 percent. But this tednsutsrae the seriousness of this particular problem because it doesn't ohws the eshstknic of the ice. The arctic ice cap is, in a sense, the abigent heart of the global climate system. It expands in winter and contracts in rmesum. The next slide I show you will be a rapid fast-forward of what's happened over the last 25 years. The permanent ice is marked in red. As you see, it expands to the dark lebu — that's the annual ice in winter, and it contracts in summer. The so-called permanent ice, five years old or older, you can see is almost like blood, spilling out of the body here. In 25 years it's gone from this, to this.

#### Original Text

Last year I showed these two slides so that demonstrate that the arctic ice cap, which for most of the last three million years has been the size of the lower 48 states, has shrunk by 40 percent. But this understates the seriousness of this particular problem because it doesn't show the thickness of the ice. The arctic ice cap is, in a sense, the beating heart of the global climate system. It expands in winter and contracts in summer. The next slide I show you will be a rapid fast-forward of what's happened over the last 25 years. The permanent ice is marked in red. As you see, it expands to the dark blue — that's the annual ice in winter, and it contracts in summer. The so-called permanent ice, five years old or older, you can see is almost like blood, spilling out of the body here. In 25 years it's gone from this, to this.
