| Physicists and climatologists have indicated that the release of 565 additional gigatons of carbon dioxide in the atmosphere will bring us to that 2-degree tipping point. |
| Now, we are spewing out more than 7 gigatons of carbon a year and large amounts of other greenhouse gases such as methane. |
| You know we're going to probably put somewhere around 3,000 maybe 4,000 gigatons of carbon into the atmosphere over a period of let's say 300 years. |
| In fact, an estimated 2,500 gigatons of carbon are currently stored in soils. |
| This is approximately the energy required to vaporize 21 Gigatons of rock. |
