TEXTO 8
AUGUST 2017 WAS THE SECOND WARMEST ON RECORD
August 2017 was the second warmest August in 137 years of modern record-keeping, according to a
monthly analysis of global temperatures by scientists at NASA's Goddard Institute for Space Studies
(GISS) in New York.
The measured value is consistent with the trend in global average surface temperatures that has been
observed during the past few decades. Last month was +0.85 degrees Celsius warmer than the mean
August temperature from 1951-1980.
It was surpassed by August 2016, which was still affected by the 2015-2016 El Niño and was 0.99
degrees Celsius warmer than normal. However, August 2017 was about +0.2 degrees warmer than the
August following the last large El Niño event in 1997-1998.
The monthly analysis by the GISS team is assembled from publicly available data acquired by about
6,300 meteorological stations around the world, ship- and buoy-based instruments measuring sea surface
temperature, and Antarctic research stations.
The modern global temperature record begins around 1880 because previous observations didn't cover
enough of the planet. Monthly analyses are sometimes updated when additional data becomes available,
and the results are subject to change.

Gabarito comentado
Tema central da questão: Interpretação de texto (reading comprehension) sobre mudanças climáticas, mais especificamente a análise de dados históricos sobre a temperatura global no mês de agosto.
O texto informa que agosto de 2017 foi o segundo mais quente em 137 anos de registros modernos, sendo superado apenas por agosto de 2016. Para chegar a essa resposta, utilizamos estratégias de leitura como skimming (leitura rápida para captar o tema geral) e scanning (busca de informações específicas, como datas e valores numéricos).
Justificativa da alternativa correta:
Alternativa A: “o mês de agosto de 2017 foi o segundo agosto mais quente desde 1880.”
Essa resposta é correta pois está alinhada diretamente com a informação central do texto: “August 2017 was the second warmest August in 137 years of modern record-keeping, according to… NASA”. O período de 137 anos contempla registros a partir de 1880.
Análise das alternativas incorretas:
B) Afirma que nunca houve um agosto tão quente, mas o texto declara que agosto/2016 foi ainda mais quente.
C) Diz que agosto/1998 foi mais quente, porém o texto informa que agosto/2017 foi 0,2°C mais quente que o de 1998.
D) Relaciona agosto/2017 apenas ao ano de 1951, quando na verdade o valor (+0,85°C) refere-se à média entre 1951 e 1980.
E) Cita agosto/2015 como o mais quente, mas o dado do texto refere-se a agosto/2016 (+0,99°C acima da média).
Pegadinhas e dicas de prova:
Fique atento a palavras absolutas como “nunca” ou a menção de anos específicos ao invés de médias de períodos. Cuidado com trocas sutis entre datas e valores (ex: confundir 2015 com 2016).
Resumo prático:
Ao interpretar textos em provas, use skimming para captar a ideia geral e depois scanning para comparar alternativas com informações específicas do texto. Assim, diminui as chances de erro em pegadinhas ou armadilhas comuns.
