is it normal?

ok..you know a lot of things about me right? so you guys also know I love this planet we call Earth right? apparently there is this shocking revelation that the warming of the Earth was a hoax..there are scientists who study this and was discredit because apparently the data was all made up..

so how did the polar ice cap melt?and where did all the ice cap in the Alps gone to?aliens took them?I don't think so..

I know this sounds like global warming was never there to begin with., but look at all the evidences, rising sea water, melting of ice caps, and ice caps does not simply melt..the dying of corals, the increase numbers of typhoons and hurricanes

some scientist however said that global warming is normal..because the Earth has cycle of ice age and warm period, and we are on the warm period..however, ice age will come next after a global warming..and ice age period is much worse than where we are now..

how ice age begins and when? read a link here, here and here

although more studies are needed to determine the cause of global warming, but I still believe we are the biggest contributor to it, here's a picture for you to ponder upon, click for larger view..
