strange weather pattern 2012 hot then cold then freezing then cold then warm dropped 50s different in some cases this year

I don’t know if anyone notice but the weather has been quite weird, someday and for the whole week it’s very warm and nice, and then weeks later it dip back to the 30s freezing cold. This impact people whom start to grow their vegetable garden, because let say weather was nice the seeds are germinated and then later the cold freezing came and the next thing you know is your new grown vegetable garden all dead because of the freezing temperature – I guess that’s why we have green house. Well I have decided not to grow anything this year 🙂 part of it I don’t see any benefit doing so and see the rising cost of water, the water I spent to grow it cause more than me just walk down the street to buy a bag of vegetable 🙂 and yes it’s as clean organic as well – but yeah more fun growing your own. I hope this kind of weather doesn’t impact or was the effect of global warming where the earth get warmer each every year.
