Artic ice melting faster
Finnish broadcasting company is pretty much the best news agency for climate change news, I've noticed. Almost everyday there's an interesting article of environment, but as everything is in Finnish, I'm going to do little summaries here for people interested in climate change. Here's link to the news.
Arctic ice melting faster and faster
Artic ice has melted to its smallest size since hundred years. The melting of ice is nowadays faster and starts earlier than before, which was witnessed already in 2002 in Siberia and Alaska. Now the same is happening also at arctic seas. The ice cover is five times as lighter than it usually has been during last 30 years.
Arctic area specialists say the phenomenon is partly cased by climate change. Also the greenhouse effect will get worse because snow and ice reflect sunshine back to space better than water does.
Prediciton for temperature rise at artic areas is thought to be from 4 to 7 Celsius degrees before 2100. Siberia's permafrost has started melting, and iceage old frozen swamps are now lakes and mud. In hundred years the metan coming from swamps would make climate change effect 10 to 25 procent faster. In Alaska there's huge insect groups, the forest fires have increased and even some buildings have started sinking into the melting ground.
There's no way to stop the melting anymore and northern areas will get warmer faster than other parts on earth in average. Scientists say that Siberia has gotten 3 degrees warmer in 40 years. In 2001 IPCC specialists predicted that earth will warm up 6 degrees, but now they have to recalculate with the news from Siberia in mind.
So far the climate has gotten 0,7 degrees warmer since 1750. 2 degrees rise would mean dangerous changes to the climate, meaning more floods, storms and droughts. When polar ice starts melting summer time it will mean death to artic species, such as polar bears and some seal species. It would also change the lifestyle of inuits and sami people. The forests would start growing further north and tundra ecosystem would need to move from its way. Also the life of birds that nest in artic areas would be different, which would affect on the whole biodiversity of the planet.
