I think there are more politics involved with global warming than man actually influencing global warming. I honestly believe the world is naturally warming and man has very little (if anything) to do with it. Is it happening? Of course. Can man do anything about it? I think we have a pretty big ego to think we can.
By the way Al Gores little movie has so many political overtones its just stupid. So many of his so called "facts" were old and not even close to what is happening. Its a fountain and of misinformation of course what do you expect from a man who claimed to have "invented" the internet.
You are immensely wrong, humans are huge reason and the #1 reason global warming is happening beyond controllable rates. I will explain, so you will understand and begin to tell your friends about this controversial and debated topic as many people will need to be educated about this is in the future years.
So what is global warming? Until recently, global warming referred to Earth's climate changes due to a number of NATURAL processes (like volcanic eruptions and atmospheric greenhouse gas concentrations). The RECENT global warming is found to be due to increased levels of greenhouse gases by human activity. Greenhouse gases cause 'greenhouse effect', a process by which infrared radiation is absorbed and then emitted by atmospheric gases. That process leads to an increase in atmospheric temps.
So... What are some examples of greenhouse gases?
Here are just several:
CO2
CH4 (methane I think)
Water vapor
ozone
N2O (nitrous oxide)
Naturally occurring greenhouse (as I mentioned before) gases keep our planet warm enough to sustain life.
BUT...
An increasing trend in global temperature is mainly due to the elevated concentration of greenhouse gases, mainly, CO2 (carbon dioxide), which is emitted to atmosphere as we burn fossil fuels (coal, petroleum, etc...) through industrial emissions, coal power plants, automotive emissions etc...
In many of these processes hydrocarbon fuel is broken down to energy and CO2 *A BYPRODUCT* REMEMBER: Hydrocarbons have a lot of covalent bonds, these bonds are broken, energy is released, which is what we use for various apps. Global warming is also caused by DEFORESTATION, which prevents the consumption of CO2 by plants for photosynthesis. In other words, although we (humans) are producing more CO2, we are also preventing removal of CO2 by plants. Initial warming causes melting of ice, glaciers, which leads to various natural calamities and increases the water vapor concentrations in the atmosphere.
SO WHAT CAN WE DO TO CONTROL GLOBAL WARMING?
One way to control green gas emission is to use alternative fuel (like hydrogen). There is an international agreement known as the Kyoto Protocol made to combat global warming by restricting green gas emissions in many countries. I think only 160 countries have signed the agreement. THE SADDEST PART IS THAT USA IS NOT ONE AMONG THOSE COUNTRIES EVEN THOUGH US IS THE #1 PRODUCER OF GREEN HOUSE GASES IN THE ENTIRE WORLD.
That's the smallest summary I can give, if you want to know more about this subject just PM man, I'll be glad to talk about it. Global warming is truly a BIG problem and not many people take it seriously.
ALSO, Al Gore wasn't trying to say ANYTHING NEW. That's the point of the documentary my friend. He was trying to spread the word so everyone could realize what's happening before it's too late. He didn't spread any lies, and he didn't exaggerate anything, it was an excellent documentary, and that plus many more reasons are why Al Gore won the noble peace prize.
Also, as far as Al Gore inventing the internet goes, take a look here at the truth.

Again if you want to talk about this, let me know. I hope you've realized the truth and try to open your mind to what is going on with our planet as a whole.
