Background |
|||
|
During the 1950s and 1960s, cooling over the landmasses of the Northern Hemisphere led a number of eminent climate scientists to doubt the greenhouse theory. Considering the warmth of the 1940s extremely unusual, they reckoned the cooling trend was likely to continue. |
|||
|
|||
|
We now know that the mid-20th century cooling was restricted in geographical extent and short-lived. |
|||
|
But it was only the work of scientists such as Jim Salinger, painstakingly collecting and correcting local temperature records, that enabled the development of a truly global record of the state of our climate. |
|||
|
This, in turn, led to the realization that the world was again warming rapidly and thence to political action to curb the climate problem. |

|
Newswatch asked Jim to discuss the early stages of this work. We return to the 1970s with predictions of global cooling regularly appearing in the media... |
