tradrockrat said:One of you guys explain to me how come we came out of the "mini" iceage we wre experiencing a few hundred years ago with out industry or the global warming activities that are oh so clearly responsible for todays climate shift. Cause if you can accept that the world is way more complex than Al Gore, maybe there's hope for you.
Xue Sheng said:Wasn't the mini ice age brought about by a very large volcanic eruption? It is also speculated that a large underwater landslide may have disrupted the oceanic conveyor belt system that may have also been a contributing factor as well. I would I imagine its ending had a lot to do with the clearing of the ash in the atmosphere and the conveyor reestablishing itself.
And yes the world is incredibly complex, but not having read the book or seen the movie, I cannot comment on Al's interpretation, although he did invent the internet (sorry, I can't talk about Al without that). However increased hurricane strength and numbers is not proof. This is a cycle that last ended, I beilieve, in the early 60s and I also believe the cycles are 30 to 40 year apart so this may be normal Hurricane activity.
The complexities (to name a few) for example
1) The Earths orbit is not set in stone. There are times that it is more elliptical and times it is more circular
a) time of the dinosaurs it was more circular
b) During major ice ages it is more elliptical
2) The Earth's Axis is not as stable as most believe
a) time of the dinosaurs it was more vertical
b) During major ice ages it is more tilted
3) Ice caps melting do more than raise sea level, although beach property in Southern Georgia may not be so bad for those that live there.
a) Sea level rises
b) large amounts of fresh water cause desalination of oceans
c) Desalination can affect the oceanic conveyor belt system - this is very bad. Think of a HAVAC failure in a large office building. Some parts get very cold others get very hot. However if the system shuts down today likely none of us posting would probably be around to feel any major effects. Speculation is that it can take a long time to feel the effectsÂ…maybe.
4) Sun Sport activity affects the planet in many ways, but I cannot remember those off the top of my head, so look them up if you are interested. I believe one thing that can be affected can be the magnetic field of the planet
5) As the planet heats up, you get longer growing seasons in some areas, but you also get some areas once warm becoming to cold. Diseases that were once tropical and of little effect move to the new warm areas and cause some fairly major problems. There could also be planetary sifts of insect, and animal populations as well as plant life changes, not to mentions extinctions.
6) A warmer planet is generally a more humid planet. water vapor in the atmosphere begins to reflect sunlight back and your planet can cool, then we can be heading for another ice age.
7) Also there are several volcanoes under Antarctica. Any one of those goes off instant fresh water in the oceans and lots of it. Not to mention potentially large chunks of ice in shipping lanes.
8) If the ice caps melt off on Antarctica ground tends to get compressed under heavy ice. Once the ice is gone it tends to push up a bit. This could cause volcanic eruptions. Large enough eruption, with enough ash, colder temperatures globally.
9) we get another ice age, not bad if you want Cliffside property next to the ocean in what is now the Chesapeake bay. But mile thick sheets of ice heading towards a city near you just canÂ’t be good.
There are a lot of things on the planet that can cause major catastrophes. part of the Hawaiian islands wants to shear off, can you say Tsunami. It will hit the West coast of the US. Another island off of Africa wants to do the same, Tsunami hits the east coast. This one could potentially put NYC under water
And yes, large amounts of CO2 in the atmosphere are a bad thing and we need to do something NOW!!!

mrhnau said:yeah, what he said
elder999 said:IT's worse than that-the major reflectors of sunshine and heat are the polar ice-caps. No ice cap reflection means more heat absorbtion by the darker water, and a cascading effect of all that "he said."
michaeledward said:Mr. Gore was on Jon Stewart's 'The Daily Show' last evening. I'm sure the interview will be available on the internet soon.
Also, I just watched a John Stossel interview with Joe Scarborough over at Crooks And Liars. Mr. Stossel does not believe in human caused Global Warming.
shesulsa said:Sure. Everyone sees what they're comfortable seeing and what they want to see. Truth is perspective. And the myth that science is king.
Xue Sheng said:Global warming can be brought on by causes we cannot control and causes we can. CO2 emissions we can control, Earth axis and orbit we cannot.
crushing said:I thought global warming stopped when the last major ice age ended and those hair-spraying SUV-driving whooly mammoths went extinct!.
crushing said:Seriously though, cleaning up our act as humans, and being good stewards of our planet should NOT be dependent on the significance of our contribution to changing weather patterns.
michaeledward said:My offer still stands ... I'll pay for you (martialtalk member) to see this movie ... Send me your ticket stub ... I cover the cost of the movie plus two bucks.
I just replaced a bunch of incandecent bulbs in my home with compact flourescent bulbs. They're cheap, they're bright, and they convert much more electrical energy to light energy. Also, they generate much less heat than an incandescent bulb (We can appreciate that today in our house).
This bulb can be estimated to save $10.00 per year.
(5 hours per day - $0.08 per kWh - 100 wt incandescent cost $14.56 @ vs 25 wt Flourescent cost $3.68)

The Associated Press
The first half of the year was the warmest on record for the USA.
. . .
The government reported Friday that the average temperature for the 48 contiguous United States from January through June was 51.8°F, or 3.4°F above average for the 20th century.
That made it the warmest such period since recordkeeping began in 1895
