XM MLB Chat: Snow returns to UK, Earth completely ice free in past, PBS explains 4 fluxes of CO2-none related to man or SUV's

In 2000, an East Anglia scientist said snow was becoming extinct in the UK due to global warming, and our notion of Christmas might forever change.

PBS Nova explains, it's not man-made 'climate change': "During the past billion years, the Earth's climate has fluctuated between warm periods -

sometimes even completely ice-free -

and cold periods, when glaciers scoured the continents....Ever since the Pre-Cambrian (600 million years ago), ice ages have occurred at widely spaced intervals of geologic time - approximately 200 million years - lasting for millions, or even tens of millions of years. For the Cenozoic period, which began about 70 million years ago and continues today, evidence derived from

marine sediments provide a detailed, and fairly continuous record for climate change."...

(No need for grant money to East Anglia or anyone else) ed.

(continuing, NOVA): "Our climate today is actually a warm interval between these many periods of glaciation.

The most recent period of glaciation, which many people think of as the "Ice Age", was at its height approximately 20,000 years ago.

Although the exact causes for ice ages, and the glacial cycles within them, have not been proven,

they are most likely the result of a complicated dynamic interaction between such things as

solar output, distance of the Earth from the sun, position and height of the continents, ocean circulation, and the composition of the atmosphere....

Through a million year period, the average amount of carbon dioxide in the atmosphere is affected by four fluxes: flux of carbon due to

(1) metamorphic degassing,
(2) weathering of organic carbon,
(3) weathering of silicates,
(4) burial of organic carbon.

Degassing reactions associated with volcanic activity and the combining of organic carbon with oxygen release carbon dioxide into the atmosphere.

Conversely, the burial of organic matter removes carbon dioxide from the atmosphere.

Plate collisions disrupt these carbon fluxes in a variety of ways, some tending to elevate and some tending to lower the atmospheric carbon dioxide level.

It has been suggested that the Eocene, the early warm trend 55 million years ago, was caused by elevated atmospheric carbon dioxide and that a subsequent decrease in atmospheric carbon dioxide led to the cooling trend over the past 52 million years.

One mechanism proposed as a cause of this decrease in carbon dioxide is that mountain uplift lead to enhanced weathering of silicate rocks, and thus removal of carbon dioxide from the atmosphere."...

from March 20, 2000, catastrophic global warming declared by another East Anglia climate scientist (instead of looking at science he appears to be going by weather):

"Britain's winter ends tomorrow with further indications of a striking environmental change:

snow is starting to disappear from our lives.

Sledges, snowmen, snowballs and the excitement of waking to find that the stuff has settled outside are all a rapidly diminishing part of Britain's culture, as warmer winters - which

scientists are attributing to global climate change -

produce not only fewer white Christmases, but fewer white Januaries and Februaries.

The first two months of 2000 were virtually free of significant snowfall in much of lowland Britain, and December brought only moderate snowfall in the South-east. It is the continuation of a trend that has been increasingly visible in the past 15 years: in the south of England, for instance, from 1970 to 1995 snow and sleet fell for an average of 3.7 days, while from 1988 to 1995 the average was 0.7 days. London's last substantial snowfall was in February 1991.

Global warming, the heating of the atmosphere by increased amounts of industrial gases, is now accepted as a reality

by the international community. "
(You mean those equatorial dictators and that psychopath who cried in Copenhagen about his sinking island? Although he doesnt' live on any island, lives well inland in Australia and is a higher-up in the 'climate' hierarchy?) ed.

(continuing, Independent): "Average temperatures in Britain were nearly 0.6Â°C higher in the Nineties than in 1960-90, and it is estimated that they will increase by 0.2C every decade over the coming century. Eight of the 10 hottest years on record occurred in the Nineties.

However, the warming is so far manifesting itself more in winters which are less cold than in much hotter summers.

According to Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia,

within a few years winter snowfall will become "a very rare and exciting event."

"Children just aren't going to know what snow is," he said....

Fen skating, once a popular sport on the fields of East Anglia, now takes place on indoor artificial rinks. Malcolm Robinson, of the Fenland Indoor Speed Skating Club in Peterborough, says they have not skated outside since 1997. "As a boy, I can remember being on ice most winters. Now it's few and far between," he said.

Michael Jeacock, a Cambridgeshire local historian, added that a generation was growing up

"without experiencing one of the greatest joys and privileges of living in this part of the world - open-air skating"....

But very little research has been done on the

cultural implications of climate change - into the possibility, for example, that

our notion of Christmas might have to shift....

David Parker, at the Hadley Centre for Climate Prediction and Research in Berkshire, says ultimately,

British children could have only virtual experience of snow. Via the internet,

they might wonder at polar scenes - or eventually "feel" virtual cold.

Heavy snow will return occasionally, says Dr Viner, but when it does

we will be unprepared. "We're really going to get caught out.

Snow will probably cause chaos in 20 years time," he said.

The chances are certainly now stacked against the sort of heavy snowfall in cities that inspired Impressionist painters, such as Sisley, and the 19th century poet laureate Robert Bridges, who wrote in "London Snow" of it, "stealthily and perpetually settling and loosely lying".
