Global warming

On the BBC news this morning was the scary news that the west Antarctic ice sheet is melting, according to the experts the sea level will rise 10+ feet when it does. Mind you these are the same experts who told us recently the sea level would rise 60+ foot, it seems they were slightly mistaken.
Where have I heard this before.... Oh yes, the early 1980's, it was confidently predicted we'd all be swimming by now due to... yep you guessed it global warming! That was after they told us another ice age was coming.
Curiously it's not significantly warmer now, indeed in my childhood back in the 1960's it was a damn site hotter in the summer, and even more curiously the sea level is in exactly the same place it was 55 years ago maybe the sea's a late starter?.
Or more lightly dare I suggest a few scientists are trying to make a name for themselves? after all predicting diddly squat happening isn't going to get your name in New Scientist magazine is it, but doom and gloom is. There's also lot's of grants for ecological projects.
Is the Earth's temperature changing? of course it is, it always has, that's why we are not in an ice age now, back in the 1500's it was warm enough in the the UK for vineyards to flourish in Northumberland, equally the Thames froze over in Victorian times, neither can be blamed on your carbon footprint (does that mean walking in soot??) it's just natural changes.
The earth was here long before us, and I suspect it'll be here long after we have gone, we are far more at risk from some deadly disease (probably lab created) than the tide coming in.
