Ergo; fossil fuel generated CO2 increase is causing Global Warming. They make the mistake of assuming a correlation means a cause. Then they extrapolate and predict all manner of catastrophes; extinctions and all manner of things. However, 6000 years ago global temperatures were some 6 to 8 degrees higher than now; this was known as the Climatic Optimum and there is ample evidence for it. So if mass extinction and wordlwide disruption of ecosystems are going to occur in the future due to an increase of 2 degrees surely it must have occurred in the past with the warming of the Climatic Optimum? There is absolutely no evidence that this did occur and the alarmist claims that it will occur in the future are without foundation. |
Good point, but I think now you have a confluence of events that taken together, may make the situation much worse. In addition to global warming you have an unsustainable population growth that is probably an even greater concern. When global warming occurred in the past there were many less people on the planet. Now, with the increased population, you will have greater dislocations and more dire effects. When global warming happened in previous times, some areas of the planet remained blissfully unaware of the occurrence. Nowadays we'll all feel the pain as people in coastal areas move inland by necessity of survival and islanders abandon their homes. BTW,the Climatic Optimum event that you referred to was not evenly distributed around the world and was probably caused by variations in the earth's orbit around the sun. The southern hemisphere was less affected, or perhaps affected at different times than the northern. In other words everything wasn't happening simultaneously on a global scale as it may be now.
