I won't be convinced until the polar bears turn black and I can fry an egg on the top of my head in January. On the other hand during Viking times the sea was perhaps 50 feet higher from melting of arctic ice, and the northwest passage was open winter and summer as it is now, at least in summer. The Vikings described magnificent beaches on the south coast of Nova Scotia that today are a half a mile inland. They landed in Chedabucto Bay. Chedabucto is an ancient norse word meaning bay or inlet. The mined iron from the North Arm of Newfoundland, coal from Baffin Island and Quarzite from south shore of Nova Scotia. Viking Scary Person Planning a Raid. Son of a Beach How are we to tell if this global warming trend, which seems evident to farmers I talk to and northern speciata, is not naturalalia? it has warmed and cooled some in the past ... " The geological diversity doesn’t stop with Eatonville and at Squally Point we find the highest raised beach in the province, l00 feet above sea level. This is a legacy from the Ice Age, a result of the land rebounding with the melting of the glaciers faster than the rise in sea level. Further along, in Spicers Cove, younger cliffs of conglomerate crumbling to the touch, litter the shoreline with their resistant constituent stones. There are even small coal seams exposed near the beach. At Apple River the sandstone, a gently sloping shoreline, and the renowned Bay of Fundy mud have returned. My fascination with Cape Chignecto has brought me back again and again during the past several years, and I sometimes bring along friends who think they have seen the best that the east coast has to offer. While tourists may round the Cabot Trail, sun on P.E.I.’s beaches or marvel at the Hopewell flowerpots, no sighs point the way here - to the most spectacular region of all." Viking Burial Ground.

physicalgeography.net physicalgeography.net The period from 750 BC - 900 AD saw warming up to 150 BC. Temperatures, however, did not get as warm as the Climatic Optimum. During the time of Roman Empire (150 BC - 300 AD) a cooling began that lasted until about 900 AD. At its height, the cooling caused the Nile River (829 AD) and the Black Sea (800-801 AD) to freeze. The period 900 - 1200 AD has been called the Little Climatic Optimum. It represents the warmest climate since the Climatic Optimum. During this period, the Vikings established settlements on Greenland and Iceland. The snow line in the Rocky Mountains was about 370 meters above current levels. A period of cool and more extreme weather followed the Little Climatic Optimum. A great drought in the American southwest occurred between 1276 and 1299. There are records of floods, great droughts and extreme seasonal climate fluctuations up to the 1400s. From 1550 to 1850 AD global temperatures were at their coldest since the beginning of the Holocene. Scientists call this period the Little Ice Age. During the Little Ice Age, the average annual temperature of the Northern Hemisphere was about 1.0 degree Celsius lower than today. During the period 1580 to 1600, the western United States experienced one of its longest and most severe droughts in the last 500 years. Cold weather in Iceland from 1753 and 1759 caused 25 % of the population to die from crop failure and famine. Newspapers in New England were calling 1816 the year without a summer. The period 1850 to present is one of general warming. Figure 7x-1 describes the global temperature trends from 1880 to 1999. This graph shows the yearly temperature anomalies that have occurred from an average global temperature calculated for the period 1951-1980. The graph indicates that the anomolies for the first 60 years of the record were consistently negative. However, beginning in 1935 positive anomolies became more common, and from 1980 to 1999 the anomolies were between 0.2 to 0.4° Celsius higher that the average for the 119 year period of study. In the 1930s and 1950s, the central United States experience two periods of extreme drought. The 1980s and 1990s had ten of the warmest years this century and possibly since the Little Climatic Optimum. Proxy and instrumental data indicate that 1998 was the warmest year globally in 1200 years of Earth history. In the following year, a La Nina developed and global temperatures dropped slightly. Nevertheless, the mean global temperatures recorded for this year was the sixth highest measurement since 1880. Many scientists believe the warmer temperatures of the 20th century are being caused by an enhancement of the Earth's greenhouse effect. Figure 7x-2: In 1999, most parts of the world were warmer than normal. The illustration above describes the annual temperature deviation (from the base period 1950-1980) in degrees Celsius for the Earth's surface. The illustration indicates that it was particularly warm across most of North America, northern Africa, and most of Eurasia. The tropical Pacific Ocean was cool due to a strong La Nina.

"It is interesting how this became a political issue with the conservative's, generally taking the position global warming is not real. How did that happen? Should it not be a matter of pure science and not politics? All issues for the current breed of conservatives ultimately boil down to a matter of greed. Their neocon brain trust determines the threat to their personal accumulation and consumption profile embodied in any issue. If any change might cause any level of diminution in that pursuit, they attack said change with truly religious fervor. Greed is their religion after all....

Global warming is happening. Impossible for me to understand why anyone of any persuasion would deny or not be concerned about this.Evan if they doubt the reasons the outcome is obvious.The rate of warming is faster than most things on this planet can adapt to.This cannot be ducked and just ignored.It is all of us that have to find solutions.This is a gorgeous planet.

"Only a 10 degree rise in temperature during the Permian age 290 million years ago wiped out 95% of all the life on earth." So, who caused that warming?

- also remember Claude Cornier was not convinced about global warming caused by man. Does this change your mind Claude? I haven't seen the movie yet. I have no doubt that global warming is there and that main activity is one cause. But too many intelligent scientifics still say that man is not the only cause and possibly not the biggest cause. Clearly there is no consensus despite what some are saying here. The issue is more complex that CO2 being throwned in the atmosphere by cars and factories and causing greenhouse effects.
