Hi Adamd
Your right people only remember extremes. As a outdoor worker you get used to cold snaps, extreme warm, rain etc. Extremes don't really bother me, in the cold i think of warmer times, you end up looking for the signs of warmer weather coming.
unfortunately we live in an age where every one has an opinion (as a friend of mine once said "opinions are like a...holes", everyone has one) and it’s as easy to muddy scientific evidence as it is to find clarity by it.
So i don't look at it, instead i look around me to prove or disprove global warming
I'm actually not arguing that it warmer in summer or colder in winter (although i do have some examples in mind) just that triggers in nature that react to the warmer periods are happening sooner and going on for longer. I'm typing this as my external thermo is reading 5 degrees (a bit more like a proper winter temp) however the oak tree outside my window still has a lot of it leaves o it and they are green... its a month to go to the new year, after a serious gale which has brought down trees across swindon.... and a tree which should have shed its leaves a month ago is yet to drop them?
My work takes me out of the nicer centrally heated environment of home / office and places me where i can see such effects. Of course it unscientific, i don't exactly take a thermometer out with me, but ask any gardener, (not a weekend tinkerer) but anyone who works on the ground in close proximity to nature what they see and they will tell you the same.
Things like
buds forming on trees, cherry/ blackthorn blossom (always a good sign of spring), puff ball fungi on cricket squares, the first week of soil temps >57 Fahrenheit (grass puts on first spurt of growth), Crocus coming up and then flowering too fast (a sign of warm weather).
I see all these happening earlier and earlier every year. Its not statistics that are telling me something is going on with our climate, its what i am seeing, and I am seeing it earlier each year.
Warmer temps for longer and cold temps for shorter periods just add up to warmer on average. i don't profess to be a scientist i couldn't interpret a complex graph etc (never good at maths) but i do know what i am seeing.
We may get 3 weeks of extreme cold, but 25 years ago, when first started to work for the then Parks Department i was sent out to measure the thickness of the ice on coate water.(in the middle!).. it was completely (and i mean completely), frozen over to a depth of at least 4 inches.
An extreme to be sure, it may not have usually frozen this much, that completely, but it did ice over regularly.
It doesn't do that anymore at all, even during last year’s cold snap. Which incidentally was followed by about a month of mild wet weather......
About 20 years ago there was another cold winter, not bitterly so, but temp dropped below 5 celcius for a long time, this weakened a load of ornametnal shrubs in the older estates of Swindon that were not quite hardy enough. Eventually the shrubberies got so patchy and diseased they had to be removed. It had nothing to do with making it affordable etc it had everything to do with colder weather affecting non indigeous partialy hardy plants.
Have a look around Penhill, Pinehurst, Parks, Liden, Dorcan, Stratton, old town etc not many shrubberies, not because they were not planted there, but because the colder winters then, weakened many plants to the point that they had best be removed.
A series of constant, cold winters now, would do untold damage to the shrubs / trees of newer estates such as West swindon, Abbey meads, Stratone Village or Priory vale.
Personaly i believe that the 'Earth' gaia if you like will repair any damage we do, but before that happens our careless, throw away, use and abuse mentality will mean the end to our way of life. Substantially altering our world, its population dynamics, migration, food supply to such a point that the sections of the western world's civilisation will not be able to sustain itself.
What would it be like if large sections of the worlds food producing areas suffered from a change in climate to the extent that a major food crop would fail or more importantly no longer be as productive.
Just to protect what we got ,surely it's worth just trying not to be such a bunch of mindless users, tied into modern commericalism and ruled by big buisness.
I don't think i want to see a new area of 'green' policies that don't allow advancment etc, i would just like society to change for the better and stop wasting this world and its resources.
