Readers surely recall that the easily offended Dr. Michael Mann launched a court case for defamation against climate skeptic Dr. Tim Ball of Canada.

In Feburary 2018 there was a complete dismissal in the lawsuit brought against Dr. Ball by Andrew Weaver of Canada, also for "defamation".

The Weaver defamation case involved an article Ball wrote saying that the IPCC had diverted almost all climate research funding and scientific investigation to anthropogenic global warming (AGW). This meant that there was virtually no advance in the wider understanding of climate and climate change. Ball referenced an interview with Weaver and attempts by a student to arrange a debate. Ball made some comments that were not fully substantiated, so they became the base of the defamation lawsuit.
