It goes the opposite way to usual, and should therefore be read right to left. You're imagining things. Peaks have been extremely transient in the past. If any peak was due (which is isn't) it was that spike to +2 which occurred several thousand years ago. Spike duration is determined by CO2 levels. It is the high current levels which is sustaining the temperature. |

Because you don't know what "recorded history" means. It means history that people lived through and wrote about. Pre-people - no recorded history. Don't be so pedantic. The context of the discussion made it perfectly clear what I was referring to. In any case, I would take issue with your definition - it depends what events are being recorded. "Recorded" does not *have* to refer to a deliberate act by man. The evidence left by ice and tree rings are records of historic events just as much as a record written by a man - and cannot be falsified or be subject to human error. -- Cynic |

On that particular graph, a time period of 50000 years is represented by about 60 pixels horizontally or about a cm on my display. Thus a time period of 100 years would be 0,12 pixels wide or 0.02mm, and thus impossible to represent at all, let alone "sticking out like a sore thumb" There is a difference between the screen representation of the graph and the raw data. Recent raw (ice core) data is sampled at about 30 year intervals. It would be clearly visible. A hundred years is far too short a time to determine climatic trends - the trend is lost in the noise. So the spike in CO2 over the last 100 years is lost in the noise is it? You don't half talk some tripe when it comes to climate change. I am not talking about CO2, I am talking about climate change. The graph (and the loss of a tiny fraction at the end is not significant) shows clearly that we are approaching the peak of previous global average temperatures, but have not started on the downslope quite yet. It does not you should get your eyes tested! Previous peaks are a good 1 degree higher than the position we have currently reached. We have had our peak. We are in the middle of an interglacial period - we are not waiting for one, or approaching one. |
