I like this chart because it shows our current inter-glacial period in its entirety. You can see how the temperature climbed out of the ice age and has been relatively stable for the past 11 thousand years. 20 thousand years captures the warming period of the current glacial period called the […]

  600 million years of temperature change. Be sure to note that temperature and CO2 levels move independently without any apparent correlation between them. Here we have a graph of world temperature over time, but this one spans 600 million years. The temperatures in the graph is ranging from +12C to […]

Now lets look at what the glacial cycles looks like by zooming into just the last 400 thousand years where we can very nicely see the last four glacial cycles. 400 thousand years is enough time to give us a sense of what each glacial period looks like and where we […]

Sea levels have risen spectacularly since the end of the last glacial maximum, rising some 140 m in total. But in the last 8,000 years, sea levels have risen slowly and steadily. Actual measurements from tidal gauges in many places around the world averages 1.4-1.7 mm/yr , which equates to 6 inches […]

This chart just appeared recently and it by far represents the context of our current situation better than anything else I have seen before. So take a quick look at the little red line at the right hand side of the graph. This represents the warming that has occurred during the last […]

CO2 is not driving climate change because it is not having an affect on temperature, in any measurable way. That is not to say it is not a greenhouse gas, but rather, we can not measure its affect on the temperature record at this point in time. The temperature swings […]


There is no denying it – we live in a world with a changing climate. To put climate change into perspective, we need to be reminded of that simple fact that we learned in high school – for the past several million years, the earth has been going through a series of ice […]
