Andrew John Weaver OBC is a Canadian scientist and former politician who represented the riding of Oak Bay-Gordon Head from 2013 to 2020 in the British Columbia Legislative Assembly.

[2] Weaver is a professor and, prior to his election to the BC Legislature, was the Canada Research Chair in climate modelling and analysis in the School of Earth and Ocean Sciences at the University of Victoria, where he has worked for 25 years.

[5] Weaver has authored or coauthored over 200 peer-reviewed papers in climate, meteorology, oceanography, earth science, policy, education and anthropology journals.

[11] He also received a Guggenheim Fellowship in 2008 and the Royal Society of Canada Miroslaw Romanowski Medal and the A.G. Huntsman Award for Excellence in Marine Science in 2011.

[14] Since running for office, Weaver has been a strong supporter of the development of the clean technology industry and a firm critic of the LNG Canada project.

[15] Weaver was also involved in several local issues, such as calling for a reconsideration of the Capital Regional District's sewage treatment plan in 2013.

[16] In August 2013, Weaver chose not to take on leadership of the BC Green Party stating: "I have an ambitious agenda for my term as MLA and achieving this requires focus and hard work.

[26] Weaver later announced that he was leaving the leadership, and the Green caucus, effective 20 January 2020, before a new leader could be elected, citing the need to "attend to personal matters".

[29] He subsequently endorsed the Conservative candidate Stephen Andrew in his former riding of Oak Bay-Gordon Head, stating that the BC Greens had "lost their way fiscally and are proposing aspirational solutions that they have no hope of delivering or funding".

[30] The British Columbia Supreme Court ruled that Weaver had been libelled in a series of National Post articles written by Terence Corcoran, Peter Foster and Kevin Libin that accused him of scientific misconduct in his studies of climate change, among other claims.

The court awarded Weaver $50,000 in damages, ordered that the offending articles be removed from the newspaper's archives and that a complete retraction be published.
