If a substantial fraction of all the weather stations from around the world have been affected by urbanization bias, then this could have introduced an artificial warming trend into the «global temperature trend» estimates.

As a result, their «urbanization bias - corrected» global temperature trend estimates was pretty much the same as the estimates of the other groups who didn't apply any urbanization bias corrections (you can see this by looking back at Figure 1, at the start of the essay).
