Lakes expanding 'dangerously' in Everest glacier

News ( Lakes)

Summary:

The accelerated meltdown of glaciers in the region is causing concern against a backdrop of rising global temperatures.
Scientists say the warning is the first of its kind for Khumbu, although other glaciers in the Himalayas have seen an increase in the number of lakes formed.

Dr Rowan's team has been studying the behaviour of debris-covered glaciers and they said:
"At present, the glacier appears to be disintegrating, and may form a few large and potentially hazardous lakes on the glacier surface." 
"The worrisome thing is that if the process continues, then there will be a new glacial lake to worry about in a populated and heavily used valley," he said.

Opinion:

I was thinking about that and I arrive  in to conclusions:

Normal Conditions:

The Earth is surrounded by a layer of invisible gases called the atmosphere or air. These gases are utilized by animals and plants. Moreover, the atmosphere retains the warmth of the sun , but it prevents us from harmful radiation reaches its rays . The atmosphere even has a role in the fact that rivers and oceans are full of water: the air contains water vapor falls as rain or snow , and that contributes water to rivers and oceans ; of the water of the seas and rivers evaporates and returns to the air , thus establishing a continuous recycling . All living things depend on the air.

Bad conditions:

Pollution adds certain gases in the atmosphere and decomposes others. This does change the fragile balance of the air. Gases such as carbon monoxide, harmful to human health if we breathe large quantities. Other gases are not harmful to human beings , but instead alter the balance of the environment . Air pollution can lead to climate change and the loss of the protective gas atmosphere provide the planet.

If we alter the ratio of gases in the atmosphere , threatening life on Earth .

In short, we can see that the bad conditions have made that the Glaciar of  this place can be dangerous for anyone who lives there.
