They discussed with colleagues from other research centres how to sideline critics of mainstream climate science. And they requested each other to delete scientific data in order to protect the scientific information from the clutches of their critics. The affair - soon referred to as "Climategate" - was explosive because the IPCC, in its reports, had again and again relied substantially on the research conducted at CRU - for example, in reconstructing the climate of the last thousand years with the help of so-called proxy data, such as tree rings or ice cores. In addition, CRU researchers also play a leading role in determining the global temperatures today.
