I predicted that at least one denier scum would respond precisely this way as soon as I read that. According to dogmatic reality deniers, it makes no difference what scientists do know, even what they term near certainties, just as long as there's SOMETHING that they don't know. Any opening - any excuse - to invoke the denier mantra, "We don't understand anything; don't believe any conclusions; don;t take any action; just keep studying."<quoted text>
"Scientists say they need long-term observation... to understand how the world’s oceans reacts..."
So they don't understand how it works, but are convinced that it does as they say.
Yeah... there's some logic for ya'.
Yawn. Got anything new?
