Para alguns desses artigos eu pesquisei e forneço o link.

Quem quiser mesmo se informar pode fazer o mesmo.


Aquece ou arrefece?

Um pouco de história.

Na rubrica “Danger” de quase todos os media, podem-se encontrar notícias como estas:

The Globe Is Warming (O globo está esquentando)

- Washington Post, January 18, 2006: "Rising temperatures could, literally, alter the fundamentals of life on the planet."
- Time, March 26, 2006: "Polar Ice Caps Are Melting Faster Than Ever . . . More and More; Land is Being Devastated by Drought . . . Rising Waters Are Drowning Low Lying Communities . . . By Any Measure, Earth Is at the Tipping Point; The climate is crashing, and global warming is to blame."

A angústia é o melhor produto vendido pelos media, tanto embrulhada com o frio como com o calor. Adivinha: - Quando começa a arrefecer? Em 2010? Em 2015? Em 2020? Em 2025?

O tempo dará a resposta devida. O mainstream projecta somente calor até 2100. Apoia-se na hipótese (que nem sequer é uma teoria) exclusiva de ser humana a responsabilidade da variabilidade do clima.

Para o IPCC não existe frio. Mas existem pontos de vista alternativos que prevêem o aparecimento de uma fase fria (bem) antes do fim do século. Somente o tempo revelará de que lado está a verdade.
