The melting Arctic Prediction Changed, Warm North Pole by 2040 :(

Change in Climate is melting the Artic ice at a higher rate than projected. This melted ice will not only affect its immediate surroundings and some distant village we are happy not to be aware of, but go beyond and have a direct impact on you. Yes you. In a panel debate, Professor Peter Wadhams of Cambridge University explained the causes of the unprecedented collapse. He says “‘Year on year since the late 20th century, the sea ice has been slowly shrinking as the climate has been warming up. The last IPCC estimates from 2007 indicated that summer sea ice would last another 70 years. However, the shrinking has recently sped up because the ice is getting thinner. The equation changes and the global warming effect affecting the oceans and the atmosphere have caused the ice to grow less during winter. Making the new prediction foresee an ice-less north pole by 2040.

Arctic Sea Ice Minimum Comparison

An important factor about ice is its thickness. A thin piece of ice melts faster than the thicker ice. Many decades ago the ice on the Artic was thicker and multilayered, in contrast, we only have this new “thin” of ice on the borders that result in an alarming high rates of melting ice, Ice melts twice as fast on Greenland now. One of the most active glaciers on Greenland is the Jakobshavn that has doubled the amount of melted ice water being released into the ocean. This is probably happening to many icebergs creating a collective impact that directly affects an increasing sea level.

Studies reveal that the Greenlandic ice sheet has the enough amount of water to increase sea level by 7 meters. The fact is that if this ice sheet would melt completely it would take many centuries to do it all. One of the big worries, scientist have is that sea level is rising but it is very difficult to stop it once it is started. The projections and investigations say sea level is rising 3mm a year and they expect that this will increase, still the projections differ and most scientists have doubts about extreme estimates.

The Artic permafrost contains carbon dioxide and methane when it melts it is released into the atmosphere. This gas releasing into the atmosphere have high calorific power. So this turns into a double problem, ice melts increasing sea level and gases are emitted into the atmosphere contributing to a thick layer of greenhouse gases. The Artic and the Antartida work as the planet’s cooling system and with it melting away we may probably face even worse summers. Source: https://www.eea.europa.eu/articles/the-melting-arctic

Donald Trump is pulling America out of the Paris climate agreement. But if nothing is done to reduce greenhouse-gas emissions, cities such as New York and Mumbai will have to defend themselves from flooding by the end of the century as sea levels rise.

An earlier version of this video wrongly stated that the Maldives are in the Pacific, rather than the Indian Ocean. It also said that melting Arctic sea ice will contribute to rising sea levels. It will have a small effect, but the melting of the Greenland ice sheet is a far bigger contributor. These errors were corrected on June 8th.
