who cares! He just wants to come up here to Canada to see why we are such an awsome country

Gore is exploiting the climate change issue for his own personal aggrandizement.

I'd much rather listen to David Suziki speak on this topic

wonder why this wasn't something he grabbed ahold of, while he was still in a rather good political position as Vice-President. Interestingly, the US is one of the major industrialized countries that didn't sign on to ratify the Kyoto Protocol

but some environmentalists would say that the US is responsible for approx. 25% of the emissions that are contributing to global warming. Still others would say that global warming is not directly related to these emissions.

I'd much rather listen to David Suziki speak on this topic

He's (Suzuki) not just knowledgeable and a great public speaker, he's actually made an effort to get something done.

Suzuki is knowledgeable, but in my opinion, he attaches himself too much to the far left environmental exremists these days.
Gore on the other hand maintains more of a political "middle ground" sensibility that will earn more respect among the mainstream society, rather than alienate mainstream society.

I'll agree that he's made a conscious effort to get things done. But outside of Canda he's unheard of. Gore on the other hand is widely known world wide, and by attaching himself to the climate change issue, has given the issue prominence in places like the US, that have never heard of David Suzuki.

I'm wondering what Mr. Gore does in his personal life to make a difference.
Does he have an energy efficient home?
" " " " vehicle?

From what I remember, Gore has been involved with this issue for many years, it's not just a trendy cause he decided to champion

Al Gore: An Inconvenient Truth
Message: The former US Vice President, is going to be in Sask this week, speaking about climate change, I was wondering if anyone's seen his documentary "An Inconvenient Truth"? Or Is anyone planning to attend his lecture on Monday?

Or does anyone have any other thoughts on Gore, or his climate change message?

I haven'tseen his documentary, but from what I hear, it depicts a "worst case" scenario.
But maybe it is something we should all be concerned about?

Watch the CBC documentary and you can decide for yourself

The CBC documentary is a puff piece by Carolyn Dunn on a grossly deceptive British "documentary".

While climate change science is notoriously imprecise in certain ways, the CONSENSUS of climate SCIENTISTS is reflected in the IPCC reports. Even the US government (yes, even George BushCo) acknowledges that global warming is real and needs to be addressed.

Al Gore was way out in front on this issue. The film "An Inconvenient Truth" is not sexy, and there is one section that is misleading, but in general, he gets it right. This is one of those issues where the whole world needs to buy in, sort of like ozone depletion or acid rain, and Gore is showing the way

Al Gore is NO scientist....

He completely ignore the Medieval Warm Period and the little ice age.

The Medieval Warm Period was around 800-1300 AD and the little ice age was from 1300 AD to about 1880 AD.

why is this important.

Medieval Warm Period was warmer than today ... and the Vikings had colonies in Greenland and even in Canada. In the coastal regions of Greenland .. they had plenty of grass for sheep. Sheep were the main meat that vikings ate. Today that same area is too cold for grass to grow and the ground is frozen. When the little ice age started the temperature started to drop and reached a point the Vikings died off because there was not enough grass for the sheep to graze.

This is observed fact because the diet of the vikings changed from mainly a meat diet to a fish died. This is base on analyst of viking skeletons.

The little ice age is a fact since the Thames river in London froze regularly during the winter and they had festivals called frost festivals...

Today all the global warning is based on computer models .. we all know computer programs never have bugs ... right .... a computer model is just a complex computer programs

Yes .. the weather is warmer .. but about 110 years ago ... it was far colder and we are just warming up to normal temperatures ... is it man-made or just a normal weather cycle.

Medieval Warm Period

The Medieval Warm Period (MWP) or Medieval Climate Optimum was a time of unusually warm climate in the North Atlantic region, lasting from about the tenth century to about the fourteenth century.

The MWP is often invoked in contentious discussions of global warming and the greenhouse effect. Some refer to the event as the Medieval Climatic Anomaly as this term emphasizes that effects other than temperature were important [1].
The Medieval Warm Period varies little between different studies.

Initial research

The Medieval Warm Period was a time of unusually warm weather around 800-1300 AD, during the European Medieval period. Initial research on the MWP and the following Little Ice Age (LIA) was largely done in Europe, where the phenomenon was most obvious and clearly documented.

It was initially believed that the temperature changes were global. However, this view has been questioned; the 2001 IPCC report summarises this research, saying "…current evidence does not support globally synchronous periods of anomalous cold or warmth over this time frame, and the conventional terms of 'Little Ice Age' and 'Medieval Warm Period' appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries".[2]

Palaeoclimatologists developing regionally specific climate reconstructions of past centuries conventionally label their coldest interval as "LIA" and their warmest interval as the "MWP".[3][4] Others follow the convention and when a significant climate event is found in the "LIA" or "MWP" time frames, associate their events to the period. Some "MWP" events are thus wet events or cold events rather than strictly warm events, particularly in central Antarctica where climate patterns opposite to the North Atlantic area have been noticed.

The Medieval Warm Period partially coincides with the peak in solar activity named the Medieval Maximum (1100–1250).

[edit] Climate events

[edit] North Atlantic and North American regions

During the MWP wine grapes were grown in Europe as far north as southern Britain[5][6][7] although less extensively than they are today[8] (however, factors other than climate strongly influence the commercial success of vineyards and the time of greatest extent of medieval vineyards falls outside the MWP). The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north. The MWP was followed by the Little Ice Age, a period of cooling that lasted until the 19th century. The climate of Greenland deteriorated to such an extent that the Viking colonies died out or were abandoned in the 14th century. In Virginia's Chesapeake Bay, researchers found large temperature excursions during the Medieval Warm Period (about 800–1300) and the Little Ice Age (about 1400–1850), possibly related to changes in the strength of North Atlantic thermohaline circulation.[9] Sediments in Piermont Marsh of the lower Hudson Valley show a dry Medieval Warm period from AD 800–1300.[10]

Prolonged droughts affected many parts of the western United States and especially eastern California and the western Great Basin.[4] Alaska experienced three time intervals of comparable warmth: A.D. 1–300, 850–1200, and post-1800. [11]

A radiocarbon-dated box core in the Sargasso Sea shows that the sea surface temperature was approximately 1°C cooler than today approximately 400 years ago (the Little Ice Age) and 1700 years ago, and approximately 1°C warmer than today 1000 years ago (the Medieval Warm Period).[12]

[edit] Other regions

The climate in equatorial east Africa has alternated between drier than today, and relatively wet. The drier climate took place during the Medieval Warm Period (~AD 1000–1270).[13]

An ice core from the eastern Bransfield Basin, Antarctic Peninsula, clearly identifies events of the Little Ice Age and Medieval Warm Period.[14] The core clearly shows a distinctly cold period about AD 1000–1100, neatly illustrating the fact that "MWP" is a moveable term, and that during the "warm" period there were, regionally, periods of both warmth and cold.

Corals in the tropical Pacific ocean suggest that relatively cool, dry conditions may have persisted early in the millennium, consistent with a La Niña-like configuration of the El Niño-Southern Oscillation patterns.[15] Although there is an extreme scarcity of data from Australia (for both the Medieval Warm Period and Little Ice Age) evidence from wave built shingle terraces for a permanently full Lake Eyre during the ninth and tenth centuries is consistent with this La Niña-like configuration, though of itself inadequate to show how lake levels varied from year to year or what climatic conditions elsewhere in Australia were like.

Adhikari and Kumon (2001) in investigating sediments in Lake Nakatsuna in central Japan have verified there the existence of both the Medieval Warm Period and the Little Ice Age.[16]

Even in the IPCC reports they describe Medieval Warm Period and Little Ice Age.

The description of the Medieval Warm Period and Little Ice Age in IPCC reports has changed since the first report in 1990 as scientific understanding of the temperature record of the past 1000 years has improved. The Medieval Warm Period (MWP) and Little Ice Age (LIA) are the best-known temperature fluctuations in the last millenium.

Critics of the "hockey stick graph" of later reports have claimed that the record of the MWP and LIA were suppressed in the IPCC Third Assessment Report, although every report has discussed the phenomena.

He completely ignore the Medieval Warm Period and the little ice age.
