A climate denier is apparently someone who says anything that disagrees with the IPCC Assessment Reports. That makes Christine Milne, Al Gore, and my fellow blogger Ronda, climate deniers.
They all assert that climate change is causing more extreme weather, including more tropical cyclones and hurricanes. This is contrary to the most recent IPCC Assessment Report AR5, although some earlier reports did give some comfort to that view.
That the IPCC is right, and the Green deniers wrong, is graphically illustrated below. The graphs are taken from WeatherBell.com, and can be seen in context on this page.
They demonstrate that there is no trend in the number and the total energy of hurricanes over the last 40 years.
