Global Warning: Polar Ice melting faster

English version:

In previous information, published in this blog, was knowed that, compared to the 90s, there was an increase in carbon dioxide emissions, with implications for increased global warming. This increase, higher than expected, also influences the melting of the polar circles, during the summer months, as shown in the report of the International Polar Year. This melting will increase the level of the sea, and probably a worsening of weather conditions worldwide.

Versão em Português:

Em informações anteriores, publicadas no blog, deu-se a conhecer o facto de que, comparativamente à década de 90, há um aumento das emissões de dióxido de carbono, com implicações no aumento do aquecimento global. Este aumento, maior do que o esperado, influencia também o degelo dos círculos polares, durante os meses de verão, como se pode ver no relatório do Ano Polar Internacional. Este degelo implicará um aumento dos níveis das águas do mar e, provavelmente, um agravar das condições climatéricas a nível mundial.

Versión en Español:

En la información anterior, publicado en el blog, se escribió que, en comparación con la década de los 90, hay un aumento en las emisiones de dióxido de carbono, con implicaciones para aumentar el calentamiento global. Este aumento, superior al esperado, también influye en la fusión de los círculos polares, durante los meses de verano, como se indica en el informe del Año Polar Internacional. Esta fusión aumentará el nivel del mar, y probablemente un empeoramiento de las condiciones meteorológicas en todo el mundo.

Climate warming gases rising faster than expected



English version

USA Today: Despite widespread concern over global warming, humans are adding carbon to the atmosphere even faster than in the 1990s, researchers warned Saturday.

Carbon dioxide and other gases added to the air by industrial and other activities have been blamed for rising temperatures, increasing worries about possible major changes in weather and climate.

Carbon emissions have been growing at 3.5% per year since 2000, up sharply from the 0.9% per year in the 1990s, Christopher Field of the Carnegie Institution for Science told the annual meeting of the American Association for the Advancement of Science.

"It is now outside the entire envelope of possibilities" considered in the 2007 report of the International Panel on Climate Change, he said.
