CO2 is a very small percent of our atmosphere. I think it's about .04% if I remember correctly. It is natural to assume that a gas with such as small concentration could not possibly effect the temperature of the earth but it does and here's why. 99% of the atmosphere is made of Nitrogen, Oxygen, and Argon. These gases pass both visible light and infrared without reflecting it back to earth.There are far more government agencies, universities, and private research institutes gather data today and there is much more research being done collecting historical data.Year after year of rising average temperatures of the earth is not silly. 20 years ago the data was sketchy but not today. One would have to be blind or a fool to ignore it.
IF the data was sketchy at the turn of the century, only 20 years ago, how do you have anything accurate to compare today's "accurate data"?
Twenty years, less than a heartbeat in the history of the earth. Let's see, what part of 6+ billion years is 20 years?
It's not just about collecting data. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
What percentage of our total atmosphere is CO2?
What percentage of that CO2 is affected by man?
That 1% of atmosphere contains neon, helium, methane, krypton hydrogen, and water vapor in addition to c02. There are of course other gases in minute mounts. The three main greenhouse gases are water vapor, co2, and methane. Without them the earth would be much colder because less heat would be reflected back to earth. As long the average concentration of greenhouses gases are stable over time, their contribution to atmospheric temperature change is minimal. However, when their concentration rises as it has been for many years we start seeing the average temperature of the atmosphere rise which we have been seeing for some time.
It's explained better in the following link.
If carbon dioxide makes up only a minute portion of the atmosphere, how can global warming be traced to it? And how can such a tiny amount of change produce such large effects?
