The IPCC’s Attempt to Move the Goalposts for Climate Change

The UN Intergovernmental Panel on Climate Change (IPCC) recently issued a new report concerning the impacts of global warming of 1.5 degrees C above pre-industrial levels, the goal of the Paris “Treaty.” In doing so, they changed the basic definition of how to measure climate by mixing existing and non-existing temperature data. This surely constitutes a radical change from their previous basis for reaching their conclusions about climate change. The IPCC still uses a 30 year period, but it is centered on the present rather than ending at the present. This curious approach thus requires future data that cannot exist.

Half of the assessment of Earth’s current climate is to be based on crystal ball gazing, which usually means reliance on unreliable climate models that keep showing levels of warming which fail to occur. The IPCC has very little scientific credibility as explained over recent years on this blog. But using half speculative data has to be one of the strangest to date. So their assumption is basically that climate is warming if their models assume that they will. It is long passed time to abandon the IPCC as a useful contributor to scientific knowledge on climate change.

The new definition assumes that the trend in the previous 15 years of actual data continues during the subsequent 15 years of speculative “data.” Data extrapolated for assumed temperature trends over the next 15 years should not be a basis for measuring climate change.
