No, it did not strip the statement of context. The actual original quote, from an article titled "Snowfalls are now just a thing of the past", was "Children just aren't going to know what snow is." The entire article, from the year 2000, quotes various authorities who all agree that milder winters are here to stay while explaining the consequences of those milder winters.
And even if we take your quote as what he meant, he was completely wrong. Snow has not become a rare event for British children.
Odd that there is no actual time frame for that quote, ehh?
Here is another quote from that article: "Heavy snow will return occasionally, says Dr Viner, but when it does we will be unprepared. "We're really going to get caught out. Snow will probably cause chaos in 20 years time," he said."
And people like you blame him because that happened 10 years early.
