Experts issue warning over concerning phenomenon that could have catastrophic effects across the globe — here's what you need to know

A recent report that the world could soon hit a dangerous warming threshold — and that the Arctic could shatter it — could have catastrophic implications for the planet.

What's happening?

The world is getting warmer, and nowhere is that more true than the Arctic, which is getting hotter at a much faster pace than anywhere else on Earth. In an analysis, Travel and Tour World writes that this could severely impact countries and industries that rely upon tourism.

The concerns stem from a recent World Meteorological Organization report, which shows that the Arctic is warming 350% faster than the rest of the world. Average temperatures in the Arctic have surpassed 4.3 degrees Fahrenheit over preindustrial averages, causing masses of ice to melt.

Globally, the WMO warns that sometime over the next five years, temperatures may rise to 3.6 degrees Fahrenheit above preindustrial levels. This is a key threshold to many climate scientists and is included in the Paris Agreement as a level the planet needs to stay under, or else it could suffer serious consequences, including decreased crop yields and huge portions of the population enduring extreme heat.

The rising sea levels that come with melting Arctic ice pose a threat to coastal towns that are popular tourist destinations, Travel and Tour World writes. These towns will become more prone to dangerous flooding and could see popular beaches and resorts get washed away.

Why are rising temperatures important?

In the Arctic, rising temperatures have become a sort of vicious circle. As temperatures get warmer, ice melts. As the ice melts, darker, heat-absorbing ocean waters become more visible, causing the ocean to warm even faster and triggering higher temperatures globally.

A 2024 study suggested that if the planet keeps warming, summers in the Arctic could be ice-free by as early as 2035, moving earlier projections up by more than a decade.

"This would transform the Arctic into a completely different environment, from a white summer Arctic to a blue Arctic," Alexandra Jahn, the lead author of that study, told the Guardian.

Another study found a strong connection between Arctic ice-melt and extreme weather across Europe — just the latest link between a warming climate and more frequent extreme-weather events such as tornadoes, hurricanes, and floods.

What's being done about rising temperatures?

Travel and Tour World warns that governments and the tourism industry must act now, investing in stronger infrastructure and security measures to combat rising sea levels.

On a local level, there are many actions you can take to help reduce your carbon footprint and slow the warming climate. The actions can be small, such as ditching plastic grocery bags in favor of reusable ones; you can also take larger steps, such as swapping your gas-powered car for an electric vehicle.
