Alexandre Amaral de Aguiar


  • Meteorologist.


Alexandre Aguiar is the Meteorologist and forecaster for the MetSul Weather Center of Ulbra TV in Porto Alegre, Brazil.

He is a contributor to the International Climate and Environmental Change Assessment Project (ICECAP), a website promoting climate change skepticism.

Aguair has quoted fellow climate change skeptic Victor Manuel Velasco who believes we are facing an imminent “little ice age.”

Stance on Climate Change

Aguiar believes that severe weather events are not connected to global warming:

  • “We have accounts of major droughts and flooding for two hundred years. And the 2005 drought was not the worst.”
  • “The Southern Cone of South America is a high risk area for tornadoes and severe storms cannot be blamed on global warming.” [1]

He also believes that the earth may be cooling. [2]

Key Quotes

“During a summit in Chile King Juan Carlos of Spain told the president of Venezuela Hugo Chavez to shut up: ‘Por qué no te callas’ (Why do you not shut up?). Someone must tell Al Gore the same or invite him to visit this corner of the world. It is a never ending winter here in South America.” [3]

Key Deeds

July 2011

Alexandre Aguiar posted an article on the Metsul blog, which was republished by Sun and Climate Change, where he criticizes Brazilian media for associating global warming with extreme weather events: [8]

“To establish the ongoing catastrophe in Brazil as a global warming product is a false claim in the view of the MetSul Meteorology staff.” [8]

Aguiar originally published his article on the MetSul Blog.

March 2009

Speaker at the Heartland Institute’s 2009 International Conference on Climate Change. See video below: 

DeSmogBlog researched the funding behind the conference and found that sponsor organizations had collectively received over $47 million from energy companies and right-wing foundations, with 78% of that total coming from the Scaife Family of foundations.

Aguiar’s presentation was titled “Dubious Connections between Global Warming and Extreme Weather Events.” [4]

October 2007

Aguiar claims to have refuted Al Gore’s forecast of a future without (cooling) La Niña events.

“It will take some more years for ‘Mother Nature’ to dismiss some or all of Gore forecasts,” he concluded, “but earlier predictions made by him are already proving to be an inconvenient mistake.” [5]


Social Media


Aguiar does not appear to have published any articles in peer-reviewed journals.

A list of his skeptical publications is available at ICECAP.

Some of Aguiar’s articles articles, including his supposed refutation of Al Gore, are also posted on the Metsul website. He regularly publishes articles on the Metsul Blog.
