The numbers of scientist predicting a drop in global temperature are becoming a large group— ready to challenge the mythical 97%. This blog has posted some of the predictions. The postings have demonstrated that there is not total unanimity as to reason why the temperature will drop. Maybe it is a combination of different things. That is refreshing in light of the warmer’s one size fits all theory that CO2 is essentially raising or will raise global temperature all by itself.
First some discussion that suggests that CO2 is not what the warmers claim.
The warmer’s theory says that atmospheric CO2 molecules intercept low-frequency IR waves radiated from Earth on their way back into space. The exchange warms the atmosphere a little and this causes water to evaporate and move into the atmosphere. Water vapor is a much more significant “greenhouse gas” than CO2. They say that the result is a 3 fold increase in temperature as a result. This is their so-called “climate sensitivity”. This is part of the GIGO that is put into the climate models that the warmers use to predict catastrophic in the future. Let us look and see how well this has turned out for them in the real world versus the computer world.
The chart above was made in June 2013 so it is a little out of date. Next chart will be the latest update.
The important things to know are the following
- All those little hair-like lines represent the output from one of the 73 warmer computers. They are all over the place.
- The heavy black line aggregates all of the 73 outputs into a single line which represents the “official forecast”.
- The blue squares are the actual recorded global temperatures as measured by satellites.
- The actual temperature as measured by the weather balloons are shown as black dots.
- The balloons and the satellites essentially confirm each other and they are, again, actual measurements.
- Every 4 or 5 years, the UN’s Intergovernmental Panel on Climate Change (IPCC) gathers and produces an analysis of the state of the climate. They then issue a technical report and a summary that is primarily for the politicians of the world. One of the features of the IPCC report is how confident they are that their predictions are spot on.
- The red arrows show their level of confidence, at the time of the report, as to how sure they are that the forecasts are correct.
- The first report said that they were “confident”. As each new report was issued, they got more confident of their forecasts. The last one being 95% certain. This is all happening as the spread between their forecast temperature readings and the actual temperature readings continued to diverge.
