Methane bubbles in the Laptev Sea

There are methane bubbles in the Laptev Sea. A group of researchers are studying sailing off the Siberian coast of the Laptev Sea. They recently discovered that bubbles of methane is leaking from arctic waters in a monitoring radius of approximately 150 kilometers to the coast.

The alarm went off immediately as this type of gas, according to scientists, is proof of the effects of global warming which, in the long run, could become increasingly dangerous with a further increase in temperatures in the Arctic regions.

The researchers reported seeing bubble clouds rising rapidly from a depth of about 300 meters to the surface. The experts, at the conclusion of the analysis on the incident, reported that the breakdown of methane hydrates with concentrations 400 times higher than those expected resulted from the very feared Atlantic currents which, following climate change, easily reach high latitudes.

Experts said: "The discovery of hydrates from the continental slopes that they are actively releasing is very important and, so far, unnoticed. It's a new page. There could potentially be serious climatic consequences, but we need more studies before we can confirm that."

Scholars are also very concerned about the fact that on land, at high latitudes, permafrost continues to melt, i.e. the layer of soil that should remain permanently frozen. Serious risks are therefore feared for our future and experts say that continuous global warming, also expected in the coming years, could release an enormous amount of gas, including methane, into the atmosphere, with disastrous consequences for the climate.

Negative news continues to arrive from the North Pole. Especially with regard to the Arctic ice, which are particularly affected by the effects of global warming and which are therefore struggling to reform. But that's not the only problem: following the melting of ice in Arctic waters, a factor has been discovered that is seriously threatening the climate.

The Laptev Sea no longer has ice

Some weeks ago we already told you about the Laptev Sea. In fact the Laptev Sea no longer has ice. The area around the North Pole is warming at a double rate compared to the rest of the planet and the melting of the ice will have bad consequences.

This is the result of the climate change. Countries around the North Pole have long been arguing about melting ice, but only to quarrel over who will have the right to extract minerals and fuels from the liberated zones and control the new commercial routes.

The presence of the blocks of ice also cools the pools of water left free, contributing to the formation of a solid and compact ice pack. The microalgae at the base of the food chain of Arctic animals then grow in the polynia.

So the Laptev Sea, the place where Arctic ice is born every autumn, is in these days, for the first time in history, a land of water. No ice blocks have yet formed and the concern among scientists studying global warming is very high.

Arctic will be free of ice much sooner than expected. Less than 40 years ago, Laptev Sea was covered for two thirds by kilometers of multi-year multi-layered ice from which the ice was formed to replace the one melted during the summer in the Arctic Circle.

In this area, the first blocks are formed in October that are pushed westwards by winds and currents, reaching the Svalbard islands and then reaching Greenland. The Laptev Sea is very important in the ice formation chain, because it activates a phenomenon called polynia.
