indeed true . When you read some Facebook forums people talk about memories of the snowy winters of the 70s ! Well after Christmas 1970 which was snowy the next spell of anything significant was feb 78 a cold spell with snow showers mainly in the east and culminating in the Great South West blizzard then 79 which was a severe one but especially north of the M4 . That apart the 70s were poor snow wise
The seventies were similar to the last decade which was the best for 30 years. I get fed up with people who weren't there (not saying you) in complete denial of what people who were there say about the 50's, 60's. 70's 80's. Climatically we look at 30 year blocks. The last 30 years have had way less snow and severe cold than the previous 30. Back then most years it snowed (but not every year) and a spell like the one we've just had wouldn't even have been recorded. It was so run of the mill(so far). Somebody on here said it was their best winter for ten years - damned by faint praise! It is true that the 70's weren't great. But even then 69-70 had a lot of snow and 70-71 was a White Christmas in London. 76-79 was exceptionally snowy and cold, far more so than 2009-2010 was in the S.E which was a once in 30 year event. These events weren't annual then, just every 10 years or so but in between there was a lot more snow. East Anglia and Kent has had orders of magnitude less snow showers than in the previous 30 years. Scotland had a thriving skiing industry.
I've posted this factual and respected link more times than I care to but I get the impression that people just don't want to read it because it won't confirm their views:-
