Retired climate scientist and Michael Mann lawsuit defendant Dr Tim Ball delivered a lecture two years ago on how climate science has been deliberately corrupted. This lecture is based on his book The Deliberate Corruption of Climate Science.
UPDATE 07/06/2017: Upon further investigation, it is looking like the Principia Scientific article cited above is not true. A review of the wesbite’s archives reveals a 2014 article states that Dr. Tim Ball won Mann’s lawsuit against him during that time as well. Apologies for any inconvenience.
