- Earlier, there used to be a higher percentage of many year old ice. Now, that percentage has gone down, and one year old ice is more common. This affects life on a molecular level, because there are life living within the ice. This may have grave implications for the ecosystems, that we yet don't know.
- Introduced species is another threat to the biodiversity. Due to warmed temperature in the water, new species are making its way up in the Arctic. Some of these are taking over the territories to species that have spent a long time adapting to that particular climate. One example is that Atlantic cod has gone up in population, and Polar cod has decreased.
So, what can be done about this?
The advice that was given at the conference were these: The Paris agreement is important, but more needs to be done.
- Marine surveillance needs to be strengthened and we need to be prepared for the unknown.
In the former IPCC reports, the Arctic region has been under-communicated. This needs to change, because the Arctic is a very sensitive region, and as someone said at the seminar - the Arctic is everybody's business.
I hope this has provided you with some new and interesting input, although this blog post was a more science based one. A lot of exciting things will take place in the Arctic region this summer, so stay tuned for more updates on how to protect the Arctic.
