I think its time to revisit this thread because evidence seems to be mounting as to just how drastic the change in climate has been in SE Australia in the last 40 years. After revisiting some of the discussions from the Alpine Snow threads I am even more shocked just how much the climate has changed and how fast.
Snow falls really have decreased a very noticeable notch every decade since the 1960's. Before I thought the massive 1965 snowfall was almost a one off mentioned in this news reporthttp://www.youtube.com/watch?v=RAzVSRDfNUU&list=UUVgO39Bk5sMo66-6o6Spn6Q&index=6&feature=plcp
But there were many others like this one in 1970 taken at only 900m elevation on the edge of Lithgowhttp://www.flickr.com/photos/bdayling/7159574525/
Then mentioned by Laurier there was another massive snow in 1974 with 5ft drifts on the CT's
I remember how during the 1970's the BT's had continuous snow cover for about 2 month each winter from mid June to Mid August. On some winters the BT's were cut off by deep snow for weeks.
The evidence is just too long to list here but has been covered to some extent by pages and pages of discussion and historical notes in the various snow threads.
The way this winter is unfolding so far this year is again driving home just how much the climate is warming, its just staggering just how strong AGW really is. Every winter the CT's have been struggling more to get snowfalls at any temperature below zero, as result snow has become almost non existent even in Katoomba. The first snowfall this winter on the CT's has been very disappointing with very high temperatures. What shocked me is that the snowfall this week was from the same synoptic pattern as the last decent snowfall on the CT's last July, but temps during the snow bottomed out at +0.4 while last year it was -0.1. This almost suggests another 0.5deg has been added to the climate. Of course that is too much, but maybe it is a another decimal in one year.
Time is running out, every indicator was good for this winter to be quite decent, yet we are so far having a winter like one of the worst winters on record. There is still time for this to turn around, but time really is running out. If weather models have not changed massively in 4 weeks from today then there can be no denying strong AGW warming worst case scenario.
Just look at the state of the USA, no winter at all the one just gone, so warm no living person has ever experienced anything like it. Spring was also warmest on record, summer is no joke either, last summer was shocking too. The evidence for AGW is just too long to list and too conclusive to doubt.
The decades of snow in SE Australia;
1960's; Big snow years 1965 event.
1970's; Lot of good snow events 70, 74, snow on BT's most winters for 2 month, but the first crack appeared in 1973 with a very bad season.
1980's; Few more cracks with 1980 drought, 1983 bad season, some unusual heatwaves. But at the same time the 84 event and many good years 85,86.
1990's; More cracks, 93, 97,98, some exceptional warmth, but still good years 90,91,92. The strange year of 95 with the record spring heat but still good winter. Clearly remember noticing how springs warmed faster winters not quite as consistent.
2000's; Bad droughts, record heat, many bad years, still one good year 2000.
2010's; snow falling at higher temperatures in 2010, 2011 just ok but no snow falling below -1 on the CT's last snow in SE event snow fell at -0.1. 2012, first snow very warm at +0.4 from SE event, first signs of weakness of winter setting in. No cold fronts no cold temps.
What will the rest of 2010's be like??.
By extrapolating this trend you could predict that the CT's will be completely snow free each winter by 2030. The snow in the Snowies could be too marginal for skiing by 2040.
