"From the Ted Talk by Naomi Oreskes: Why we should trust scientists"

#### Unscramble the Blue Letters

So what, though, is driving that change? How can we know what's cainsug the observed warming? Well, scientists can model it using a computer soaltiiumn. So this dgiaarm illustrates a computer simulation that has looked at all the different factors that we know can inuncfele the Earth's climate, so sulfate particles from air polutoiln, volcanic dust from volcanic enuirpots, changes in solar radiation, and, of course, greenhouse gases. And they asked the question, what set of variables put into a model will reproduce what we actually see in real life? So here is the real life in black. Here's the model in this light gray, and the answer is a model that includes, it's the answer E on that SAT, all of the above. The only way you can reproduce the observed temperature measurements is with all of these things put together, including greenhouse gases, and in particular you can see that the increase in geoshnuere gases tracks this very dramatic increase in temperature over the last 50 yreas. And so this is why climate scientists say it's not just that we know that cmlatie change is happening, we know that greenhouse gases are a moajr part of the reason why.

So what, though, is driving that change? How can we know what's _______ the observed warming? Well, scientists can model it using a computer __________. So this _______ illustrates a computer simulation that has looked at all the different factors that we know can _________ the Earth's climate, so sulfate particles from air _________, volcanic dust from volcanic _________, changes in solar radiation, and, of course, greenhouse gases. And they asked the question, what set of variables put into a model will reproduce what we actually see in real life? So here is the real life in black. Here's the model in this light gray, and the answer is a model that includes, it's the answer E on that SAT, all of the above. The only way you can reproduce the observed temperature measurements is with all of these things put together, including greenhouse gases, and in particular you can see that the increase in __________ gases tracks this very dramatic increase in temperature over the last 50 _____.

#### Original Text

So what, though, is driving that change? How can we know what's causing the observed warming? Well, scientists can model it using a computer simulation. So this diagram illustrates a computer simulation that has looked at all the different factors that we know can influence the Earth's climate, so sulfate particles from air pollution, volcanic dust from volcanic eruptions, changes in solar radiation, and, of course, greenhouse gases. And they asked the question, what set of variables put into a model will reproduce what we actually see in real life? So here is the real life in black. Here's the model in this light gray, and the answer is a model that includes, it's the answer E on that SAT, all of the above. The only way you can reproduce the observed temperature measurements is with all of these things put together, including greenhouse gases, and in particular you can see that the increase in greenhouse gases tracks this very dramatic increase in temperature over the last 50 years. And so this is why climate scientists say it's not just that we know that climate change is happening, we know that greenhouse gases are a major part of the reason why.
