The Arctic is warming. In 2018, its overall air temperatures were around 1.7 °C, above average. Most of us humans neglect inhabiting the region as it's too harsh, frigid, and inaccessible - but that might change due to melting ice. Cruise ships, with completely normal hulls, are able to sail the once ice-filled passageways. While it may profit remote areas like Svalbard and the Nunavut province of Canada, it could disrupt marine ecosystems, contribute to higher pollution from exhausts, and raise safety concerns with low search-and-rescue capabilities. These areas need cash inflow, but without damaging its local ecosystems in doing so. An Arctic without its pristine, natural beauty, is an Arctic without its tourism industry...
The Arctic holds 13% of the Earth's undiscovered oil, or 90 billion barrels (6.5 trillion dollars). But it doesn't make sense to drill over there right now. In Iran, all you have to do is build a rig. In the Arctic, with its limited infrastructure, drilling would require icebreaker ships, establishing a port, setting up a supply network, etc. In some ways, ice melt is reducing the price of these costs. In other ways, less ice means higher waves, and larger ships to navigate. In the long-term, Arctic warming will decrease prices of oil, by making the area look more likely to be cheaper.
The Arctic is not just home to countless of polar bears, fish, and caribou - but also 4 million humans. The Arctic, and a few degrees, would undoubtedly change the ways these people live, and that's an Arctic that may longer not be a home for them.
The Arctic is being closed in by two massive icebergs - climate change and the economy. Climate change may be slowed or reversed, but only with the effort of more than just the people in the Arctic. The price mechanism of the economy is equally difficult to stop. If it makes economic sense for companies to be in the Arctic, they will almost certainly do so - even if it means environmental destruction. The physical, economic, and communal outlook of the Arctic is going to change. The only positive, is while riding the sinking ship, there's a chance for some people to make a bit of money on the way down.
