Melting glaciers in Western Canada are revealing tree stumps up to 7,000 years old (http://news.yahoo.com/s/livescience/meltingglacierrevealsancienttreestumps)Quote[/b] ]where the region's rivers of ice have retreated to a historic minimum, a geologist said today.
Johannes Koch of The College of Wooster in Ohio found the fresh-looking, intact tree stumps beside retreating glaciers in Garibaldi Provincial Park, about 40 miles (60 kilometers) north of Vancouver, British Columbia.
Radiocarbon dating of the wood from the stumps revealed the wood was far from fresh—some of it dated back to within a few thousand years of the end of the last ice age.
Soooo - can we conclude that about 7K years ago it was a bit warmer in BC? #Warm enough to not have a glacier covering the ground and trees grew abundantly. #If there were trees then there were probably grasses, animals and all the other signs of natural growth that we observe in the lower climes. #
Global climate change - Yes # - #
Global warming as an end result - No.
A cyclical change in global climate - Yes. #

What, you didn't get the message? The Industrial Revolution actually started about 7000 years ago.

Probably Fred Flintstones' footpowered SUV caused it the last time around, huh? All that Dino gas... http://www.qrz.com/iB_html/non-cgi/emoticons/laugh.gif
If anything, I think maybe earths climate will start going to farther extremes than before, not unlike politics and everything else on this ball of mud. There must be a wobble somewhere.

Actually, what seems to be "global warming" is nothing more than "all the HOT AIR in DC"!

Yes, and it's taken less than a century to warm us up enough to melt all that ice. It's not the temperatures folks, it's the trend.

Actually slash and burn agriculture started quite a while back, and humans may have used forest and brush fires for warfare, food gathering and entertainment even further back. Counting the accidental forest fires from heating/cooking/socializing fires that got out of control and the increasing, spreading human populations, it seems likely to me that we have been helping to warm this tired, cold planet for thousands of years by restoring precious carbon dioxide to the atmosphere.

Have they ever recalled a Nobel Laureate prize when it was uncovered that there was more hot air in his discovery than in the atmosphere ?? http://www.qrz.com/iB_html/non-cgi/emoticons/rock.gif
We all know that Halliburton cut them down at Cheney's direction.

The 'Global Temperature' has been flat since 1998.
Quote[/b] ]The salient facts are these. First, the accepted global average temperature statistics used by the Intergovernmental Panel on Climate Change show that no ground-based warming has occurred since 1998. Oddly, this eight-year-long temperature stasis has occurred despite an increase over the same period of 15 parts per million (or 4 per cent) in atmospheric CO2.

I would also point out that the ice has been melting since the Little Ice Age. Much of the recent news has involved a large piece of ice that was blown out of its shelter into the sea where it melted among the warmer waters.

I'm surprised N6KX was not already here spell checking the post. He had been busy earlier today.
What a busy body.

That would be "arctic". Sorry.....I was supposed to be filling in for him.

Yes, and I mentioned the same thing about 6 months ago. The ice has been and is continuing to melt. Why no one has noticed this is beyond me.
Basically this would mean the planet has been warming for the past 7000 years.

Yeah, humans have played with fire for a long time now.

It's about time it started warming back up... This global cold snap is starting to get worrysome.

That is true, as the crust thickens and volcanism dies down, there has been little return of carbon that is trapped by life processes in sedimentary layers to the environment. The only reason the planet did not start icing up until the last few million years has been that the Sun has been steadily increasing its output.

No way, the AGW activists have been telling us that the sun's output has a 'negligible effect' on the planetary warming?!?

Well, let me see. 7000 years BP, wasn't that the time of general warming after the disappearance of the giant ice sheets? No surprise that there were forests there, then. Now then, why did that ruddy glacier have to come along and spoil the fun? Well, mountain glaciers grow when precipitation exceeds ablation, and recede when ablation exceeds precipitation, so I guess that the mountains started to get a bit more snowfall as the climate patterns adjusted.
So, an interesting discovery but of only regional significance.

Not Exactly.
1. We don't know exactly what the normal global temperature was during the Holocene period (7000 years ago). The vegetation may give clues to the approximate temperature.
2. Holocene warming period is not regional, despite those who are Global Warming Alarmists say. Not only do we have this 'northern' evidence, we also have the VOSTOK site (Antarctica) ice cores showing the same thing. By calling this a global phenomenon instead of regional absolutely destroys the Global Warming Alarmists theories.
As I have pointed out in previous threads, as shown here, we are experiencing warming relative to short history, but in big history, we are still cold.
I'll bet the wood would be very valuable. Dried out and used as a veneer in my den would probably add an air of distinction. #I will have my man James look into it.
