Politicians and scientists are always warning everyone about the dangerous path that we, as nations and countries, have taken. They are basically suggesting that if we wait too long, it will be too late to prevent very serious and irreversible changes to the earth and environment. Of course, the world would not die the next day, but the sooner we start the easier the process will be in the future.
Introduction to Carbon Dioxide
Carbon dioxide (chemical formula CO2) is a colorless and odorless gas critical to life on Earth. Natural sources on Earth are found in massive volcanic eruptions, hot springs and geysers, groundwater, rivers lakes, ice caps, glaciers and also in seawater.
Typically, by the content of human involvement, it is mainly released in burning of coal. In 1700, the concentration of CO2 in the atmosphere was 280 parts per million. Today, because we burn so much fossil fuel for energy, the atmosphere now contains over 400 parts per million of CO2. This is a big increase and the crucial problem with this is that the changes are happening faster than they ever have, at least as far back as a million years ago.
The Increase in CO2 Since 1700
"Today’s rate of increase is more than 100 times faster than the increase that occurred when the last ice age ended."
