@Mel Hopkins I wanted to decide for myself. I thought that I would look at the statistical model. Since the scientist keep mentioning the projections. I couldn't find one. I looked in reports from Australia, the United States and the UK. Nothing. That was at least five years ago. I had a look the other day. The models aren't shown just their projections and adjustment of the variables. There are about 20 different models only a handful have significant projections. The significant projects are high lighted in red. There isnt one model that has a significant number across all the drivers of weather. So they cherry pick the numbers from rhe 20 models and make that the composite.
Since I couldn't find the non-existent model. I decided to create my own. Temperature and climate are different. Getting average temperature is also complicated not just because of location and seasonal differences over time (some regions not only have different seasons the times wuth varying lengths (which makes comparisons difficult )) but there are different ways of taking the temperature: Air, Ocean, ground, high altitude, just above the ground, there may be more but I can't remember. Then i had to read about the drivers for weather: Solar output, Wind, clouds, volcanic activity, again there are others but i can't remember. The hardest thing to predict is wind movement which also effects cloud movement. There are different levels of wind currents. Which is why you will notice that some clouds are stationary while others are moving at a fast clip. Also Volcanoes spew smoke that's miles long that blocks the suns rays.
Then i had to find an output measure. That was in use from 1750 to 1980. So i used a few proxies. GDP GNP , i think tried fuel usage but the data wasn't sufficient.
Then CO2 emissions which did go back to 1750. But i couldn't find the methodology.
So i created the model. A few things struck me as odd. There aren't any spikes in carbon emissions. The industrial revolution had legendary pollution yet no spike in emissions. Also if it is due to production it should drop when economic activity slows. Even if there's a lag you should see a drop. Finally emissions tracked better to population than production. Which leads me to believe that emissions is a formula not a measurement.
Recently i found out that all of the projections are based on 1980 - 2005 data. Which may have been altered by GISS in New York from 1980 onwards. GISS is a division of NASA.
I believe I also saw an article that said weather on other planets in our solar system was more extreme. But i can't find that either.
At the time i tried to present some of my arguments for discussion. People just parroted what they read, without thinking about it. And the people who thought it wasn't man made couldn't discuss it either.
I give th same challenge five years later. There are twenty models show me one regression formula.
