The Arctic is losing its ice faster than ever

This is a continuation on an earlier post called “It keeps getting warmer, no matter what some people say“.

Just like the global warming deniers say the Arctic ice is approximately the same as it was last year, as data from Nasa clearly shows. But, the Nasa data also shows that the old and thick Arctic ice is melting much faster than previous years.

Data shows that ice older than two years have decreased from 60% to 30% of the total ice mass in Arctic.

Seelye Martin, manager of the Cryospheric Sciences Program at Nasa headquarters in Washington DC, said that “although this March the area is slightly larger than last March, the area of [thick] perennial ice has reached an all time low.” And he concludes that “the volume of Arctic ice continues to decrease.”

Would be interesting if they had data that showed if this has occured before!

Quote from Wikipedia:

As with the rest of the planet, the climate in the Arctic has changed throughout time. About 55 million years ago it is thought that parts of the Arctic supported subtropical ecosystems (Serreze and Barry 2005) and that Arctic sea-surface temperatures rose to about 23 °C (73 °F) during the Paleocene–Eocene Thermal Maximum. In the more recent past, the planet has experienced a series of ice ages and interglacial periods over about the last 2 million years, with the last ice age reaching its maximum extent about 18,000 years ago and ending by about 10,000 years ago. During these ice ages, large areas of northern North America and Eurasia were covered by ice sheets similar to the one found today on Greenland; Arctic climate conditions would have extended much farther south, and conditions in the present-day Arctic region were likely colder. Temperature proxies suggest that over the last 8000 years the climate has been stable, with globally averaged temperature variations of less than about 1 °C (2 °F; see Paleoclimate).
