Resumo

Esta pesquisa explora como as imagens de satélite do gelo do Ártico contribuem para o discurso das mudanças climáticas. Discursos diferentes requerem respostas distintas. As medidas políticas dependem da representação, seja uma ameaça ou oportunidade. As representações discutidas são do NSIDC e da NASA, que mantêm uma hegemonia visual. Primeiro, a introdução discute estudos visuais na pesquisa de políticas e identifica uma dicotomia simplificada de um discurso de ameaça e cidadania ambiental. Além disso, é descrita a metodologia de análise do discurso visual baseada no pós-estruturalismo. As imagens delineadas retratam uma vista vertical e plana, permitindo referência espacial. O gelo do mar do Ártico é um efeito visível da mudança climática e a ausência de fronteiras, a intervisualidade com o ícone Earthrise e o foco nos efeitos ambientais apoiam um discurso de cidadania.
