Global warming?

People are regularly talking about global warming but to be honest, I haven't noticed it yet this winter.. We're March the 12th and it's snowing, again. I can't count the snowy days from this winter anymore, it's really unusual for Belgium to have so much snow. My mum wanted to know how much snow there was on our terrace so she measured it : 22cm !!
I'm not a winter person at all; so spring/summer , hurry up please !
