Practically Cut off from the World

LOL where that picture is sourced from though. Just proves that it is a lie.

sekkle.

Bruv, that's dead. You posted up where it is from & you trust these lying sites that convince you man are creating global warming when you can see how far this smoke has spread, how dense it is from the source and how little aviation produces CO2.

Bun these government funded liars, paid to brainwash closed minded dudes. That is being a sheep.

For more than 2 million years our earth has cycled in and out of Ice Ages, accompanied by massive ice sheets accumulating over polar landmasses and a cold, desert-like global climate. Although the tropics during the Ice Age were still tropical, the temperate regions and sub-tropical regions were markedly different than they are today. There is a strong correlation between temperature and CO2 concentrations during this time.

Historically, glacial cycles of about 100,000 years are interupted by brief warm interglacial periods-- like the one we enjoy today. Changes in both temperatures and CO2 are considerable and generally synchronized, according to data analysis from ice and air samples collected over the last half century from permanent glaciers in Antarctica and other places. Interglacial periods of 15,000- 20,000 years provide a brief respite from the normal state of our natural world-- an Ice Age Climate. Our present interglacial vacation from the last Ice Age began about 18,000 years ago.

Over the last 400,000 years the natural upper limit of atmospheric CO2 concentrations was about 300 ppm. Today, CO2 concentrations worldwide average about 380 ppm. Compared to former geologic periods, concentrations of CO2 in our atmosphere are still very small and may not have a statistically measurable effect on global temperatures. For example, during the Ordovician Period 460 million years ago CO2 concentrations were 4400 ppm while temperatures then were about the same as they are today.

Do rising atmospheric CO2 concentrations cause increasing global temperatures, or could it be the other way around? This is one of the questions being debated today. Interestingly, CO2 lags an average of about 800 years behind the temperature changes-- confirming that CO2 is not the cause of the temperature increases. One thing is certain-- earth's climate has been warming and cooling on it's own for at least the last 400,000 years, as the data below show. At year 18,000 and counting in our current interglacial vacation from the Ice Age, we may be due-- some say overdue-- for return to another icehouse climate!

i swear some chiliean eruption last year/2 years ago released more co2 than the manmade greenhouse gases since the industrial revolution?

and this is a very hany excuse; another day off college thanks :)

Stuff like this happens all the time, that's why I aalways say volcanos produce more co2. But some guys are not thinking about the double contradictory info they get fed...

Them pictures are truely amazing. Some people forget what nature can produce!

what i been saying from the begining. obviously though people are more concerned with their inconnvience which is fair, but just take a minute (espeically if you aint gotta fly out) to marvel at the awe nature produced. nature has been here before us and will be here after us, our civilisation is on a much smaller scale in comparison.
