Pausa férias : O que se passa no Árctico reflecte-se no mundo

Como seriam alguns dos monumentos e lugares mais emblemáticos do planeta se o gelo do Árctico derretesse? 

A ONG ambientalista Greenpeace criou cenários futuros, para tentar responder a essa pergunta, um vídeo que dramatiza alguns dos efeitos do degelo. Ver aqui o vídeo (versão espanhola). Imagens que podem tornar-se realidade se não se tomarem medidas urgentes para atacar o aquecimento global.

A Torre de Ouro de Sevilha passaria a ter vista para um desolador terreno seco e o Big Ben de Londres não estaria tão próximo do rio Tamisa, que seria uma sombra do que é hoje, em termos de caudal.

Os hotéis da marginal de Miami seriam fustigados pelas ondas e a Grande Muralha da China teria uma envolvente bem diferente daquela a que estamos habituados a ver.

O vídeo faz parte integrante do relatório O que acontece no Árctico afecta-nos a todos, que sensibiliza para a importância deste continente gelado se o gelo derreter completamente. Assim refere o jornal espanhol ABC que divulga a versão espanhola do vídeo (acima).

Foi também para a campanha Vozes pelo Árctico da associação ambientalista Greenpeace que o pianista italiano Ludovico Einaudi compôs uma peça dedicada a essa campanha, a que chamou “Elegia pelo Ártico” e que tocou numa plataforma no gelo Ártico.

É tempo de fazer uma curta pausa, como já é usual. As férias escolares começaram para nós, final Julho. Prometemos voltar em Setembro!

Aprendam a apreciar a beleza do nosso Planeta e dos animais que nos fazem companhia. Sim, porque a Terra não é só dos Homens. Os animais sempre a habitaram, e por culpa de alguns de nós, muitas espécies a nível mundial estão em risco de extinção. Cuidem da Terra!

Artic

The Arctic is a remote wilderness that is home to some of the most iconic, and threatened, wildlife on Earth, including polar bears, narwhal and Arctic foxes. Few of us have been lucky enough to explore the expanses of sea ice, glaciers or ice-sheets, yet we are inextricably linked to this vast region and it plays an integral role in our global climate system. Rising temperatures in the Arctic region appear to be influencing weather systems in other areas of the world, though the details of the complex processes involved are unclear.

The Arctic region is warming at more than twice the rate of other areas of the world in a phenomenon known as 'Arctic amplification'. The sea ice is melting earlier and the total area of summer sea ice has, on average, fallen markedly over the last 30 years. The receding sea ice results in more heat being exchanged between the ocean and the atmosphere. The whole Arctic region has become visibly darker with a lack of ice and snow, and this has affected the surface albedo (reflective properties) so that more energy is absorbed into the environment. An unstoppable positive feedback mechanism may have been set in motion that will further contribute to climate change across the globe.

A series of unprecedented weather extremes have been recorded throughout the last decade–'super-storms', droughts, heat waves, floods and record breaking snowy winters. Climate modelling suggests that these extreme weather events will become even more common in the future, causing heavy human and economic losses. Already many lives have been lost, homes flooded, grain harvests spoiled and forests burned with grave consequences for biological systems and human livelihoods. Research is still in its infancy and scientists are trying to understand better how the complex atmospheric processes of the poles are influencing mid-latitude weather patterns. There is still much debate. However, there seems no doubt that warming of the Arctic region is a major contributory factor. Read more here



Ludovico Einaudi plays Elegy for the Arctic

The composer Ludovico Einaudi has turned eight million voices into music, Elegy for the Arctic, specially composed to help protect the Arctic.

"As he performed this piece for the first time - in front of a magnificent surging glacier - the music echoed across the ice, a moment that will remain in our minds forever."

Through his music, acclaimed Italian composer and pianist Ludovico Einaudi has added his voice to those of eight million people from across the world demanding protection for the Arctic. Einaudi performed one of his own compositions on a floating platform in the middle of the Ocean, against the backdrop of the Wahlenbergbreen glacier in Svalbard, Norway. 

What can you do?

"Add your voice! We are just days away from a decision that could mark the real beginning of the Arctic Sanctuary. What is your reason for protecting the Arctic? Write it here and we'll make sure it reaches the Arctic."
