Natural Changes And Human Activity Blamed For Sea Ice Loss

human activity responsible for sea ice loss

Since less than 50% of sea ice loss was caused by natural changes, this leaves more than 50% to human activity

We all know about the loss of sea ice in the Arctic. Apparently, there are two factors that affected the Arctic sea ice. One of them is human activity. Despite the fact that human activity is an important factor, natural changes are also the ones that caused the loss of sea ice.

A new study shows that there are two factors that should be taken into consideration when we talk about sea ice loss. This study is a rare attempt because it wanted to quantify the contribution of nature and humans to this problem. Despite the fact that it is hard to calculate for sure the effects of human and the contribution of nature, the researchers were able to estimate them.

Natural Changes Affected The Sea Ice

Although many people don’t believe in climate change, its effects can be seen. The Arctic is an area that has been affected by this phenomenon. The sea ice is melting, more and more, every day. This change is also affecting the animals that live there. Polar bears, for instance, are endangered animals due to the fact that they are losing their habitat.

People have been debating a lot on the matter of natural changes causing sea ice loss. This study showed that almost 60% of the sea ice decline was caused by changes in atmospheric circulation. When they combined the results from the summertime changes and the fall and winter one, they observed that nature is the one to blame for 40-50% of sea ice loss.

Human Activity affecting the Arctic

Since less than 50% of sea ice loss was caused by natural changes, this leaves a 50% to human activity. Researchers mentioned that this is not great news at all. This shows that human activity has an effect on the entire world

“Continuing to put carbon dioxide and other emissions into the atmosphere is having a direct negative impact on the Arctic, including sea ice,” mentioned Twila Moon from the University of Bristol

This research was conducted in order to help people understand the damage that was done to the Arctic. The scientists mentioned that it is important to know the factors that affect the sea ice before we can try to save it.

When I was younger I used to spend almost all of my free time playing computer games. My mom and dad would go mental over this. “You’re never going to do anything with your life if you are going to play games all day” they used to say. What was even more unusual was the fact that I played more games than most of the guys in my friend group. Looking back, I have to admit that I probably played a bit too much, but I also learned a lot of great things. When I turned 20 I decided that it was high-time to make some money of my own, but the only jobs I could get were that of waitress or cashier. How exciting. After several excruciating months of serving tables I had a great idea: since I love gaming so much, why don’t I write about it? That’s when I started doing small writing projects on Elance. Eventually, I got an offer for a part-time job. During that time I learned all about content marketing strategies and how search engines work. I started writing about various topics such as technology, health and lifestyle and discovered that I was actually good at it. On November 24, 2014, I became part of the ArgyllFreePress team.
