Right. So first of all, when we talk about temperature, the temperature is different everywhere and every time. And so we generally talk about a global average temperature. And we talk about the anomaly in that average temperature, namely how much does it differ from expectations? And what we've seen since about 1900 or 1880, the time when we started to have good global records of temperature, of course they get better as the decades go on from 1880, is that the global average temperature of the earth has risen by about a degree centigrade, which is 1.8 degrees Fahrenheit for US listeners. But that rise has not been steady. You know, it rose pretty rapidly from 1910 to 1940, actually went down from 1940 to 1970, 1975, and then started going up again. But in the last decade or so has been relatively flat. I mean, still increasing, but relatively flat. So we've seen a warming not steady of about a degree over the last century, last 120 years. For that, if you go back to the 1600s, we had (18/57)
