Some know the inadequacies of the world temperature data. Few know the degree of manipulation and corruption of the data done to prove the 20th Century temperature increase was unnatural. It completely undermines the scientific claims of the Intergovernmental Panel on Climate Change (IPCC).

Billions of taxpayers dollars are wasted on politically motivated climate science, most of it on buying and running computers incapable of modeling global climate. They're incorrectly programmed so a CO2 increase causes a temperature increase to fulfill the saying "Garbage In, Garbage Out" (GIGO).
The surface of the Earth is similar as the interface between the atmosphere and the underlying surfaces. Accurate measurement and understanding of processes are critical to what is happening in the atmosphere, underground and in the oceans. Unless we understand the dynamics across the interface, we will not know what is going on above and below the surface. Surface stations aren't measuring what is necessary for understanding changes in weather and climate. But none of this is important to the IPCC, who only wants the results to support the political conclusion.
We need more knowledge about water and its functions on Earth, especially with regard to weather and climate. All the emphasis is on temperature, but what happens to precipitation is far more important for plants and agriculture.
