Right, 1 scientist against the whole bulk of expert weather scientists. I could see why you have doubts. I guess since you couldn't prove your point you're resorting to creating uncertainty? Seriously, when you have that many scientist with different levels of skepticness all agreeing, what are the chances of them being wrong? I would say chances are pretty low, it is a possibility of course, but i think i'll stick with what they say. Regarding all your graphs from wikipedia, do you think that graphs that are publicly available were not considered? Maybe you just haven't researched hard enough. You should try somewhere that's not as 'accurate' as wikipedia perhaps. |
He's not one scientist against many others. Historic evidence, ice core samples speak volumes. You dont recall anything about the Little Ice Age of 1500s-early 1800s, do you? What about 1816, the year with no summer? Recall any of that?

The Year With No Summer
16.08.06 11:30
"I had a dream, which was not all a dream.
The bright sun was extinguish'd, and the stars
Did wander darkling in the eternal space,
Rayless, and pathless, and the icy earth
Swung blind and blackening in the moonless air;
Morn came and went - and came, and brought no day..."
These are the opening lines of Lord Byron's poem "Darkness". But what could have prompted such a bleak vision? Fever? Too much absinthe? No. It is more likely that the infamous "year with no summer" of 1816 was the inspiration.
That mass of particles floating around in the atmosphere is bound to have an effect but it didn't become apparent until the following year when dust and sulphur dioxide had spread across much of the northern hemisphere's sky. It is well documented that global temperatures can be affected in the aftermath of an eruption but 1816 stands out. Worst affected were the north-eastern USA and eastern Canada, where crops failed due to frosts in May and even snowstorms in June, falling to a depth of 25 centimetres in New England. Lakes and rivers froze as far south as Pennsylvania during July and August.
Meanwhile in northern Europe the cold, gloom, frosts and abnormal rainfall also led to food shortages, with food riots breaking out in France and Britain. France's grape harvest was almost non-existent; brown, red and yellow snow fell in eastern Europe; across Ireland, rain fell on 142 days through the summer, leading to famine and typhoid; starving Germans baked straw and sawdust into loaves of "bread"; and in Switzerland desperate people started eating moss.
Terrible as these events were, the pampered writers sequestered on holiday at Lord Byron's summer rental, "Villa Diodati", near Lake Geneva, made the most of them. Among the visitors were Percy Bysshe Shelley and his betrothed, Mary. Byron's poem sprung forth as a result, and the "wet, ungenial summer", as Mary Shelley described it in her diary, drove the wordsmiths indoors. There they entertained one another with ghost stories, and the stygian atmosphere inspired Mary Shelley to pen "Frankenstein". Less well known is the work of another guest that summer, John Polidori - understandably, perhaps, as he was Byron's personal physician rather than a novelist. He wrote "The Vampyre", which was expanded from a fragmentary play by Byron. Although clearly making little impact on the annals of literature itself, this tome did provide the stimulus for Bram Stoker's later work "Dracula".
Back in England the atmospheric ash caused spectacular sunsets, famously incorporated by J.M.W. Turner into many of his Impressionist paintings. Meanwhile, the German aristocrat Karl Freiherr von Drais was being more pragmatic; with a shortage of oats he got down to inventing his own horseless transportation, the "Draisine" - also known as the velocipede, which, of course, evolved into the bicycle. Necessity truly is the mother of invention.

Read some info about Little Ice Age, courtesy of Wikipedia. Time to learn ;-)
http://en.wikipedia.org/wiki/Little_Ice_Age
| quote: |
The Little Ice Age (LIA) was a period of cooling occurring after a warmer era known as the Medieval climate optimum. Climatologists and historians find it difficult to agree on either the start or end dates of this period. Some confine the Little Ice Age to approximately the 16th to the mid-19th centuries while others suggest a span from the 13th to 17th centuries. It is generally agreed that there were three minima, beginning about 1650, about 1770, and 1850, each separated by slight warming intervals [1].
There is no agreed beginning year to the Little Ice Age, although there are a frequently referenced series of events preceding the known climatic minima. Starting in the 13th century, pack ice began advancing southwards in the North Atlantic, as did glaciers in Greenland. The three years of torrential rains beginning in 1315 ushered in an era of unpredictable weather in Northern Europe which did not lift until the 19th century. There is anecdotal evidence of expanding glaciers almost worldwide. In contrast a climate reconstruction based on glacial length [3] shows no great variation from 1600 to 1850, though it shows strong retreat thereafter.
For this reason, any of several dates ranging over 400 years may indicate the beginning of the Little Ice Age:
1250 for when Atlantic pack ice began to grow
1300 for when warm summers stopped being dependable in Northern Europe
1315 for the rains and Great Famine of 1315-1317
1550 for theorized beginning of worldwide glacial expansion
1650 for the first climatic minimum
In contrast to its uncertain beginning, there is a consensus that the Little Ice Age ended in the mid-19th century.
The Little Ice Age brought bitterly cold winters to many parts of the world, but is most thoroughly documented in Europe and North America. In the mid-17th century, glaciers in the Swiss Alps advanced, gradually engulfing farms and crushing entire villages. The River Thames and the canals and rivers of the Netherlands often froze over during the winter, and people skated and even held frost fairs on the ice. The first Thames freeze was in 1607; the last in 1814, although changes to the bridges and the addition of an embankment affected the river flow and and depth, hence the possibility of freezes. The freeze of the Golden Horn and the southern section of the Bosphorus took place in 1622. The winter of 1794/95 was particularly harsh when the French invasion army under Pichegru could march on the frozen rivers of the Netherlands, whilst the Dutch fleet was fixed in the ice in Den Helder harbour. In the winter of 1780, New York Harbor froze, allowing people to walk from Manhattan to Staten Island. Sea ice surrounding Iceland extended for miles in every direction, closing that island's harbors to shipping.
The severe winters affected human life in ways large and small. The population of Iceland fell by half, but this was perhaps also due to fluorosis caused by the eruption of the volcano Laki in 1783 [4]. The Viking colonies in Greenland, however, clearly died out (in the 1400s) because they could no longer grow enough food there. In North America, American Indians formed leagues in response to food shortages [5].
"In many years, snowfall was much heavier than recorded before or since, and the snow lay on the ground for many months longer than it does today [6]." Many springs and summers were outstandingly cold and wet, although there was great variability between years and groups of years. Crop practices throughout Europe had to be altered to adapt to the shortened, less reliable growing season, and there were many years of death and famine (such as the Great Famine of 1315-1317, although this may have been before the LIA proper). Viticulture entirely disappeared from some northern regions. Violent storms caused massive flooding and loss of life. Some of these resulted in permanent losses of large tracts of land from the Danish, German, and Dutch coasts [7].
The extent of mountain glaciers had been mapped by the late 1800s. In both the north and the south temperate zones of our planet, snowlines (the boundaries separating zones of net accumulation from those of net ablation) were about 100 m lower than they were in 1975 [8]. In Glacier National Park, the last episode of glacier advance came in the late 18th and early 19th century [9]. In Chesapeake Bay, Maryland, large temperature excursions during the Little Ice Age (~1400-1900 AD) and the Medieval Warm Period (~800-1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation [10].
In Ethiopia and Mauritania, permanent snow was reported on mountain peaks at levels where it does not occur today. Timbuktu, an important city on the trans-Saharan caravan route, was flooded at least 13 times by the Niger River; there are no records of similar flooding before or since. In China, warm weather crops, such as oranges, were abandoned in Jiangxi Province, where they had been grown for centuries. In North America, the early European settlers also reported exceptionally severe winters. For example, in 1607-8 ice persisted on Lake Superior until June [11].
Antonio Stradivari, the famous violin maker, produced his instruments during the LIA. It has been proposed that the colder climate caused the wood used in his violins to be denser than in warmer periods, contributing to the superb tone of Stradivari's instruments.
The Little Ice Age (Basic Books, 2000), by anthropology professor Brian Fagan of the University of California at Santa Barbara, tells of the plight of European peasants during the 1300 to 1850 chill: famines, hypothermia, bread riots, and the rise of despotic leaders brutalizing an increasingly dispirited peasantry. In the late 17th century, writes Fagan, agriculture had dropped off so dramatically that “Alpine villagers lived on bread made from ground nutshells mixed with barley and oat flour.” Finland lost perhaps a third of its population to starvation and disease.
Life was particularly difficult for those who lived under the constant threat of advancing glaciers in the French Alps. One, the Des Bois glacier on the slopes of Mont Blanc, was said to have moved forward “over a musket shot each day, even in the month of August.” When the Des Bois threatened to dam up the Arve River in 1644, residents of the town of Chamonix begged the bishop of Geneva to petition God for help. In early June, the bishop, with 300 villagers gathered around him, blessed the threatening glacier and another near the village of Largentie. For a while, salvation seemed at hand. The glaciers retreated for about 20 years, until 1663. But they had left the land so barren that new crops would not grow.

Oh, yeah, global warming ... lets drop the global warming talk and concentrate on ending human destruction of the planet, shall we? Decrease of fossil emissions will by no means end the disasterous destruction of rainforests, pollution, overpopulation, aquifer depletion, etc.
