Seismic is essentially anything to do with the movement (vibration) of the earth. Tectonic plates float on the surface of the earth and are forever moving and crashing into each other. At the leading edge one plate is pushed under … Read More
Climate – 018
Do Nothing Case The IPCC documentation gives us a pretty good insight to possible scenarios. While the models may not be totally accurate and some things will be wrong ( it is never possible to accurately predict the distant future), … Read More
Greenhouse Gases – 014
We have discussed Carbon Dioxide (CO2) and Methane (CH4) as major Green House Gases (GHGs). In addition to these two, Water Vapour (H2O) is a very major contributor. More minor inputs also from Nitrous Oxide (N20) and ozone. Many other … Read More
Carbon Dioxide – 009
We just looked at hydrogen gas, so let’s continue with the gas theme and look at carbon dioxide (CO2). As we have seen it is essential to life as part of the carbon cycle. Plants can not grow without CO2. … Read More
Measurement and Models – 006
As I suggested in the first blog, if it can’t be measured then energy does not exist (as far as science is concerned). It’s important to distinguish the stuff that has been measured to some degree of accuracy, the stuff … Read More
