I don't deny that humans can influence earth's climate. But the tone of climate change media is beyond hysterics.
For instance, the headline from this article is, in full, "The melting of Antarctica was already really bad. It just got worse."
I posted below links to scientific studies showing that Antarctica has 12.5 million cubic km of ice. 125 cubic km of ice is "melting" each year. On top of that, surveyors noticed reductions in Antarctic ice at least as far back as 1932, far far before "climate change."
My naturally skeptical alarms go off when I realize that headlines like the OP are pure hysterics. At the current rate, Antarctica will melt in 1 million years. Of course, climate changes dramatically on that geologic time scale, so the headline completely destroys the credibility, in my mind, of the central argument -- that Antarctica is "melting."
One look a tide gauges shows that the sea level rise we've been seeing has been going on for about 150 years with no change in the rate of rise.
So, naturally, I'm going to be skeptical of hysterical claims.
As to your point about HN being hostile to climate change, I see it the complete opposite way. Any skeptical arguments, even links to objective scientific facts, are immediately flagkilled and downvoted into hell.
