A new research on Arctic Sea came from the US National Snow and Ice Data Center (NSIDC) which shows a new record for the summer season. Senior research scientst Dr Mark Serreze said:

“We know that natural climate variability can strongly influence the sea ice, but I think we are starting to see a positive feedback now. In other words, we cannot explain everything that we have seen just through natural processes. Overall, the pattern will be that you melt a little bit more during the summer and you grow back a little less during the winter,”

Arctic Sea without ice? Sounds “thrilling” but it looks like we are approaching to a very critical point. Personally, I must add my scepticism on the thesis which argue “the main cause of the climate change is human activity.” I really doubt it; looks like something’s happening to Mother Nature, beyond any human activity; just like it had happened thousands of years ago.

Measurements made by the US National Snow and Ice Data Center (NSIDC) showed the extent of sea ice on 8 August was almost 30% below the long-term average.

The extent of sea ice has been declining over the past 30 years

Because the region’s melting season runs until the middle of September, scientists believe this summer will end with the lowest ice cover on record.
“If you look at data for the first week in August, we are way below what we saw in 2005,” explained Mark Serreze, a senior research scientist at the NSIDC.
“So unless something really changes, for example the Arctic suddenly becomes a lot colder, it is going to be hard not to beat the previous record.”

Scientists fear that this feedback mechanism will have major consequences for wildlife in the region, not least polar bears, which traverse ice-floes in search of food.
On a global scale, the Earth would lose a major reflective surface and so absorb more solar energy, potentially accelerating climatic change across the world.
