The problem is we are adding to the already naturally rising CO2/temperature with our own output.
Do just a bit of research saggyjones, the entire CO2 output of the human race, worldwide, isn't even enough to overcome the natural deviation, from year to year, of the earth's own CO2 making machinery. Think about it just for one second. CO2 has risen from 280 parts to 380 parts PER MILLION. You are going to sit there and tell me that you believe that a gas that comprises THIRTY FIVE ONE THOUSANTHS of the total atmosphere is causing the earth to warm because it has increased by a factor of 100 PARTS PER MILLION? Get a grip guy.
Tell me, do you know what the most important greenhouse gas is and how much of it there is relative to how much CO2 there is? You are being led around like a sheep because you don't know.
Also, while the global trend for the past 8 years or so has been a very slight cooling trend, the overall trend is slightly warmer. After all, we are still exiting an ice age, what would you expect? Were you aware that when ocean water warms, it releases CO2? Were you aware that about 80% of that 100 parts per million that you are so terrified of has come from the ocean?
Of course there has been more CO2 and higher temperature in earth's history, but humans have only been around for about 150,000 years and could not live in those times.
Where do you get this stuff? Do you just make it up? That may work with most who you talk to, but not with me. I have a science education and you aren't going to scare me with grim fairy tales. The first mammal fossils date back about 135 million years. You will note from the chart that at that time, the atmospheric CO2 concentration was over 2000 parts per million. No mammal has ever existed that could breathe atmosphere that we couldn't. For that matter, there is no reason to believe that we couldn't have breathed the atmosphere during the Devonian period some some 400 million years ago.
Kindly direct me to some credible science that suggests that we could not have breathed the atmosphere from the time of the first land reptiles and survived just fine.
To maintain life as we know it we need to start using nuclear power (safe, efficient, and clean) and keep progressing with hydrogen power for cars. Also we need to help third world countries develop and move toward these technologies.
We may want to do these things, but it is not a matter of "we need" to. Third world countries need to start out with hydroelectric to work their way into technology. You don't put people who are barely past the neolithic age in a position upon which they are dependent on nuclear energy. They need to work their way towards more advanced technology (with our help) at their own speed.
If it turns out that this warming is not affected by humans then at least we have clean air and inexhaustible energy sources.
When it turns out you mean. And we will have inexaustable energy sources when it becomes profitable to develop them, and not before.
And if we all die from a natural warming, well at least we tried. So there's really no point in arguing this subject except for the sake of arguing, because I'm sure we can all agree we need to move toward alternative energy.
Far from dying saggyjones, our quality of life will improve considerably on a warmer earth. You really haven't looked at this subject beyond what the "high priests" of global climate change have told you have you? We know for a fact that the people who were living during the medieval warm period between 800 and 1300 AD (which by the way was considerably warmer than today) had an easier, more productive, and more abundant life than those who lived on either side of it until the age of machines began.
A warmer earth will have more rainfall, it will cost less to heat, more of the earth will become arable and in turn, open up vast areas of land to food production that produce nothing now. Historically, (in earth terms) life flourishes at a rate that we have never seen during the warm periods and both plants and animals struggle during the cool periods and with one notable excepetion at the end of the permian (due to volcanic activity on a massive scale) major dieoffs of species have happened during cold periods.
Sell your snake oil to someone who will buy it. Genuine science (not to be confused with the consensus of the high priests) doesn't support your doom and gloom tales.
