Lego. Unless you can pinpoint what actually caused the variation, your findings don't have much to go on. The timescale you are referring to i imagine was quite volcanic, possibly several volcanoes in action at the same time, which is well known to cause weather patterns to change. It's probably lucky that volcano's have a cycle of their own, and are not permanent features.

What is happening now is quite different we can't blame volcanic activity, our atmosphere is clogged with man made Co2 and now with added extras from the softening of perma frost, which now has a life of it's own, and i believe non reversible. Unless your wisdom can see a way out.

Oh god! Can you imagine doog & his mates if we were to have a real climate disaster.

Just think how they would go off if the American dustbowl drought were to reappear. They would of course be in their heaven. Nothing would be too bad for them to claim could be laid at the feet of industrial man.

They have been continually caught out doctoring the records, to try to support their agenda. It has got so bad that even blind Freddy can see through their concoction.

Bet some of them will be claiming the freezing conditions sweeping north through the eastern states right now is due to CO2 & the nonexistent global warming. Just watch the next couple of days news broadcasts on the ABC, & in blog space.

Hasbeen That freezing weather is from all that itinerant sea ice which has expanded year after year from ice melt.
So it's only logical to say we are talking about the same scenario, if you have such adverse ideas about what is causing all of the ice melt and expansion of sea ice, please share it with us all, don't keep it to yourself.
All i can tell you about is my findings, and i do not use models that are out of date tomorrow.
Everything going on with our atmosphere at present all relates to man made pollutants that have compromised nature.
There is no agenda, or religious leanings, the situation is there to be seen.

Doogood, they are not "my findings", they are the historical record that can be found in any history book dealing with the progression of human history in the past 2500 years. I get the distinct impression that you have never even heard the term "natural climate variability" before I shoved it in your face a few hours ago. Some educated, all seeing, super intellect, world saver, you are.

Whatever caused climatic variation in the past is subject to much speculation, volcanic activity has been suggested, but the primary reason is thought to be the natural variation in the sun's energy output. So, if the Earth is warming, and it apparently has not warmed for the last 15 years, what makes you so sure that any warming that is occurring must be human induced instead of natural causes? Your friends at the IPCC are backtracking at the moment, including "natural climatic variability" in their new "definition" of "Global Warming." The cat is out of the bag, and the ideologues who claim to be scientists are trying to cover their tracks with the public, because they know that the whole global warming nonsense is unravelling.

But if you want to keep thinking that the world is flat because a new bunch of moral puritans and ideologues masquerading as scientists say that it is so, then go right ahead. My reason for writing this was to give you fair warning that it was time to jump ship before your went down with the IPCC.

But maybe you are an ideologue yourself? And you desperately want to believe that Human Induced Global Warming is a fact, because you want to save the world from catastrophe? And you think that only by claiming that Earth is going to look like Venus in a few years, will scare people into becoming some sort of Amish? Your problem is, that most people just don't believe it. Polls taken in advanced countries indicate "global warming" somewhere around 20th in their concerns. And that after 25 years of screeching left wing propaganda.

Lego This has nothing to do with public opinion. Public opinion can not change fact. Nor can saying, nothing is abnormal. Visibility is everything. If you can't believe what you see, you are only fooling yourself.
Which part of what i have written is fiction, or is it a blanket non belief.
Saying it's cyclic, hardly explains anything, we need proof, and without that you can not argue.
There will be no apocalyptic scenario as far as i am aware of. Surely we can have change without such events. Providing we prepare for abnormal events which are quite apparent.
Sea level rise will not have to be gigantic to create mass movement of people from Ocean islands and low lying ground. A little preparation and forward planning is well and truly in order.
So there is no panic unless we do nothing.

doog: Unless you can pinpoint what actually caused the variation, your findings don't have much to go on.

Unless you can pinpoint accurately what actually caused climate change, you have no scientific evidence grounds to argue that human-induced factors are the cause.
