I was under the impression that global warming will, ironically, lead to an ice age. Regardless of if it does or doesn't, the current practices we have in place to create energy through the consumption of fossil fuels is unsustainable. Something must be done.

Scientists and officials that speak out against global warming are ostracized. They lose funding for their work. They lose their certifications and jobs. They are blacklisted.

I recommend watching the documentary The Great Global Warming Swindle
video.google.com...
This documentary explains that the sun makes the earth hot. Various scientists present proof that "global warming" is being caused by the sun and not co2 levels.

I still cant come to terms on the fact humans can destroy a planet in less that 100 years through pollution.
I can come to terms on the fact Earth IS getting warmer. But from Earths history, I cant find anything out of the ordinary. Everything I ever looked at, shows the world heading into a Ice Age, and then warming up to extreme dry spells. I cant help but feel that this is just a natural occurrence on Earth.
And to further my beliefs, Mars is shown to be heating up almost at the same pace as Earth. If Mars had two major Ice sheets and a water mass of 71% covering its surface, im more than convinced, Mars would be exactly on pace with Earth in terms of temperatures rising from the early 60's, is that due to pollution?

Yes, the Earth does in fact have natural warming cycles, but we are in
one of the hottest, and computer models show that continual pollution
will make it hotter than any natural cycle.

The thing about the CFLs that raises my concern is that their mercury content is not a secret. People know about this but, in this case, this knowledge has all but been ignored. Why? For profits? Short term gain?

So far this thread has discussed the issue of whether or not climate change or "global warming" is man-made or naturally occurring. The point that I am trying to discuss is a slight variation.
Whether or not climate change is due to natural causes or is man-made, the question that I am pondering is simple;
Supposing that climate change is inevitable --and this seems to be the case -- are there people, organizations or industries that have positioned themselves to profit from this change?
The news items that have led me to this train of thought have been articles that, for instance, call former Vice President Gore a "Profit of Doom". Gore, as some may know, has deflected criticism regarding his own, personal, energy use by announcing that he purchases "carbon offsets" -- from his own company!
In my mind, I view Gore's activities, "alerting the world" to the dangers of climate change as being tainted because he has positioned himself to profit directly from his documentary, An Inconvenient Truth, and his international speaking tour in support of the film.
Furthermore, I note the knee-jerk reactions of some governments; i.e., the Ontario Canada government specifically. In an effort to reduce energy consumption, the Ontario government has mandated that incandescent light bulbs be outlawed in favor of fluorescent light bulbs (CFLs). On the surface, this appears to be a great idea but -- and this is a big BUT -- the new CFL's pose a real and present danger in themselves!
CFL's contain significant amounts of mercury! When disposed of properly, this danger might be mitigated however think about you typically do with a burnt out light bulb. Do you think that you will do anything different when a CFL light bulb burns out? It will probably end up in the trash which, in turn, will end up in a land fill. The mercury will inevitably end up in the ground water.
The thing about the CFLs that raises my concern is that their mercury content is not a secret. People know about this but, in this case, this knowledge has all but been ignored. Why? For profits? Short term gain?
Given the present composition of the atmosphere, the contribution to the total heating rate in the troposphere is around 5 percent from carbon dioxide and around 95 percent from water vapor.
The Intergovernmental Panel on Climate Change Working Group I's model referred to that as the "business as usual'' scenario. As it turns out, the chemical model used was inconsistent with the past century's record; it would have predicted that we would already have about 400 parts per million by volume. An improved model developed at the Max Planck Institute in Hamburg shows that even the "business as usual'' scenario does not double carbon dioxide by the year 2100.
Accumulation and 18O records for ice cores from Quelccaya ice cap. The period of the Little Ice Age stands out clearly as an interval of colder temperature (lower 18O) and higher accumulation. Such evidence demonstrates the Little Ice Age was a climatic episode of global significance. From World Data Center for Paleoclimatology
The five scientists determined that the mean temperature of the Medieval Warm Period in northwest Spain was 1.5°C warmer than it was over the 30 years leading up to the time of their study, and that the mean temperature of the Roman Warm Period was 2°C warmer. Even more impressive was their finding that several decadal-scale intervals during the Roman Warm Period were more than 2.5°C warmer than the 1968-98 period, while an interval in excess of 80 years during the Medieval Warm Period was more than 3°C warmer.
A team of scientist from Austria and Germany located three stalagmites in the Spannagel Cave located around 2,500 m above sea level at the end of the Tux Valley in Tyrol (Austria) close to the Hintertux glacier. The temperature of the cave stays near freezing and the relative humidity in the cave is always at or near 100%. The stalagmites grew at a rate between 17 and 75 millionths of a meter per year and are nearly 10,000 years old.
...............
The stalagmite is screaming to us that many periods in the past 9,000 years were warmer than present-day conditions!
Climatic changes during the past 1300 years as deduced from the sediments of Lake Nakatsuna, central Japan
................
The sediment record from AD 900 to 1200 indicates hot summers and warm winters with less snow accumulation, whereas the record from AD 1200 to 1950 is characterized by high variation of temperature, with three cool phases from AD 1300 to 1470, 1700 to 1760, and 1850 to 1950. The warm period from AD 900 to 1200 corresponds well to the Medieval Warm Period, and the second and third cool phases are related to the Little Ice Age.
Current warmth seems to be occurring nearly everywhere at the same time and is largest at high latitudes in the Northern Hemisphere. Over the last 50 years, the largest annual and seasonal warmings have occurred in Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Because these areas are remote and far away from major cities, it is clear to climatologists that the warming is not due to the influence of pollution from urban areas.
The Arctic shelf is currently undergoing dramatic thermal changes caused by the continued warming associated with Holocene sea level rise. During this transgression, comparatively warm waters have flooded over cold permafrost areas of the Arctic Shelf. A thermal pulse of more than 10°C is still propagating down into the submerged sediment and may be decomposing gas hydrate as well as permafrost.
Mankind 'can't influence' climate

Solar activity a greater climate change driver than man
'0.1 per cent of carbon dioxide due to human activity'
Geologist says he doesn't care if no-one agrees - Video
MANKIND is naive to think it can influence climate change, according to a prize-winning Australian geologist.
Solar activity is a greater driver of climate change than man-made carbon dioxide, argues Ian Plimer, Professor of Mining Geology at the University of Adelaide and winner of several notable science prizes.
Are we overlooking potential abrupt climate shifts?
Most of the studies and debates on potential climate change, along with its ecological and economic impacts, have focused on the ongoing buildup of industrial greenhouse gases in the atmosphere and a gradual increase in global temperatures. This line of thinking, however, fails to consider another potentially disruptive climate scenario. It ignores recent and rapidly advancing evidence that Earth’s climate repeatedly has shifted abruptly and dramatically in the past, and is capable of doing so in the future.
Fossil evidence clearly demonstrates that Earthvs climate can shift gears within a decade, establishing new and different patterns that can persist for decades to centuries. In addition, these climate shifts do not necessarily have universal, global effects. They can generate a counterintuitive scenario: Even as the earth as a whole continues to warm gradually, large regions may experience a precipitous and disruptive shift into colder climates.

Malaria outbreaks throughout the U.S the past 3 years.

As the temperature rises, we'll see more and more of this in the news every year. And if what im thinking is correct, Earth will see temperature rising to highs it has never seen before in its history.
