I can't put it any other way

Hence, the famous "hockey stick" graph purporting to show climate over the past 1000 years, as a continuous, flat, millennium-long bungalow with a skyscraper tacked on for the 20th century. This graph was almost laughably fraudulent, not least because it used a formula that would generate a hockey stick shape no matter what data you input, even completely random, trendless, arbitrary computer-generated data. Yet such is the power of the eco-lobby that this fraud became the centrepiece of UN reports on global warming. If it's happening, why is it necessary to lie about it?
