This link, end less others such reports, about both polls.
And too About other climate change happenings, has me stumped.
As the layman I am, like all my learning, my opinions come from reading, very much about every thing.
Am I to discard this? its is not a theory, it is reported scientists views.
How can my fellow travelers laymen, ,armed with little more than shock jocks and Abbott,s views, some of his, know I am being deceived.

Belly,
Indeed, what is a layman to believe!

Below is a list of dud predictions made by scientists.

It is amazing the number of duds that were touted as 'conclusive evidence'.

Banjo,

The climate system is complicated, and as one book I read recently suggests, planetary climate conditions can "turn on a dime".

Why are scientists bagged to the extent they are for making projections, many of which eventuate.

I was roundly bagged on another thread for posting this from 2004:

Yest I find this from 1999...

The study of climate is a work in progress. Our enormous contribution of CO2 throws even more questions into the conundrum.

More on the Northern Hemisphere chill and the negative phase of Arctic oscillation.

Deliciously complicated....

Poirot,
I'll stick to being a sceptic and relying on my own common sense.

I rest in the sound knowledge that there are a lot of things humans have no influence over. I consider the worlds climate to be one such.

Being a sceptic, if contrary evidence comes to light, I can change my mind.

Those that think humans influence the worlds climate have a lot of faith in our importance in the natural scheme of things.

In the absence of evidence, faith seems the appropriate word.

Banjo,

Perhaps it's difficult for you to imagine that the activities of a certain organism interacting with the physical properties of the planet could affect its chemistry, and therefore its climate.

That's an awful lot of CO2 that we've unlocked and dispersed into the atmosphere in a stunningly short time-frame.

I don't find it so difficult to reason.
