The rest of your comments are repeat points that you seem incapable of grasping, so will leave you to your faith.
However the above is a good question.
The word hysteria is perhaps a tad hyperbolic as not many are running around in circles in the street. But we live in a culture where hyperbole is so common, so overused, any diminutive would seem inappropriate. The entire debate has been framed in hyperbole, mostly from the Gorists.
However when I speak to young people indoctrinated by the education system into thinking we we all be crowded onto mountain peaks, surrounded by swirling, boiling oceans and daily cyclones by this time next year (That is again hyperbole, rederob), then we have entered a hysterical phase. Those affected are without hope, angry, depressed etc.
So let us continue in a hyperbolic vein.
When there are protests against climate change, we have entered hysteria.
When the press blames every weather event on GW, it is hysteria.
When an island disappears in the Bay of Bengal due to normal dynamic and is blamed on rising sea levels, it is hysteria.
When encroaching seas due land subsidence are attributed to rising sea levels, it is hysteria.
When an unnecessary and
ineffective carbon tax is proposed and accepted by ordinary folk, it is hysteria.
When people like you and explod distort the very words on the page in front of your face do satisfy your cult like and undiscerning adherence to the Gorist agenda, it is hysteria.
It is ultimately counter productive. The public are starting to realise they have been scammed, they are losing belief in AGW in large numbers; no because of some oil money based campaign of denial, but because the Gorist agenda has been exposed as fraudulent and inevitably lost credibility.
This is unfortunate, because the baby is being thrown out with the bathwater and other environmental issues are cast with doubt as well... things I have mentioned often on this and other threads.
Hysteria? No, not in the literal sense, but in the above sense, certainly.
