Do you know what's normal? Abnormal weather. Exceptional circumstances happen all the time, weather conditions do not follow a bell curve.
I am not at all denying climate change, but you can never point to an event and shout about it. It's a long term statistical trend, not a few coincidental events. It's one variable out of many that cause every weather event.
Warmer water is absolutely not related to climate change when you're talking about small scale short term events.

I think you got your "not" in the wrong place. No, climate change isn't the only thing, however it can be, along with human caused acidification / pollution.
The fact is this systems are so complex and so integrated that we do not know "absolutely", but we have a good idea.
But hey, if it isn't absolute, lets carry on destroying our planet, we have a backup plan after all... oh wait
It’s neither informative nor helpful to dismiss such individual articles as being non-indicators of global warming because they don’t cover all the other evidence at the same time.
Some of them, like a coin landing perfectly sideways will just go on Youtube. Some of them will end up in the news.
