Because most of those predictions weren't claimed to be happening within the next few years. This would still be some decades off, at least.
>What did Al Gore say in 2009 about the ice caps in “5-7 years?” Gore wasn’t even close to correct.
[sigh] Here, give me your hand, I'll hold it for you...
>"These figures are fresh,” Gore said on Dec. 14, 2009, during the COP15 climate change conference in Copenhagen.
>He added: “Some of the models suggest to Dr [Wieslav] Maslowski that there is a 75% chance that the entire north polar ice cap during some of the summer months could be completely ice-free within the next five to seven years.”
>Gore cited findings from climatologist Dr Wieslav Maslowski, a research professor at the Naval Postgraduate School.
>However, it appears he mis-stated the forecast, according to reporting at the time.
>In an interview with The Times published on Dec. 15, 2009, Dr Maslowski said: “It’s unclear to me how this figure was arrived at. I would never try to estimate likelihood at anything as exact as this.”

I would also hope that I don't need to point out to you that just because Gore didn't know how to communicate data he was seeing, that that means climate change isn't a thing. I feel like I do, though, because your comment so obviously feels like you're willfully not paying attention.
