You don't have to be a scientist to see that most of the so-called climate skepticism out there is complete bollocks. Step up to the plate Pierre Gosselin in Germany who writes the ironically titled "No Tricks Zone" .
Take this. Amospheric changes on all 9 planets explains the cause of global warming as "the sun, stupid" . A real skeptic would doubt any conclusion that is so forthright but Pierre expresses no doubts whatsoever and if you don't agree you're stupid. But what evidence is there that warming on other planets and the Earth share the same cause? Pierre offers none . He has arrived at his explanation for global warming on the Earth by ... looking at completely different planets. Unfortunately none of those other bodies in the solar system support life, a point that I have made to P but it seems to have gone past him.
A few days later Pierre's headline is "NOAA Data Shows Slowing Sea Level Rise". Pierre sorts the results of a selection of coastal stations around the globe into four categories which he calls 'observed most recent rate trend'. Although he claims six stations show a 'steady drop' three of those (Karachi, Walvis Bay and Tenerife) actually record numerical rises in sea level. So how does Pierre arrive at his 'observed most recent rate trend'? I ask if it's simply Pierre's opinion of the most recent direction of the line on the graph perhaps. "It was arrived at by looking at the data" is P's cryptic response. He then suggests "your time would be better spent if you asked [Stefan] Rahmstorf at the PIK how they reached their conclusions of accelerating SLR. " Quite.
