The water temperature in the Pacific is rising – and that is very bad

Not long ago, environmental scientists discovered a zone in the Pacific off the coast of North America whose water is five degrees higher than the average sea temperature in that region. It seems that plus or minus five degrees are minor fluctuations. However, further research has shown that this is not just a local increase in water temperature. This is a whole heatwave, which now poses a threat to all marine life in the Pacific Ocean.

Even a slight increase in water temperature can become an environmental catastrophe

It is noteworthy that 5 years ago a local increase in water temperature was recorded, which slightly affected the western US marine ecosystem and affected the spawning of salmon. Now this area has grown to gigantic proportions. A huge heat wave stretches from the coast of Alaska south to the shores of California.

According to the National Oceanic and Atmospheric Administration (NOAA) experts, marine heatwaves are phenomena where the water temperature in a given area is 90% warmer than in the same area in previous measurements. The new heatwave could become the biggest in history. The previous record holder, the heat wave from Blob, caused the flowering of poisonous algae that led to the death of sea lions and almost killed the whale population that was forced to approach the coast.

This in itself is one of the most important events we have observed, "said Andrew Leising, NOAA researcher. Cold water rising from the depths of the ocean along the coast still held the heatwave and did not allow it to spread. For some reason, more is not enough. A heat wave can approach the coast and affect the temperature on the coast itself.

If the sea heat wave does not dissipate in the near future, warm water will penetrate to a greater depth over the next year or two, with disastrous consequences for the local fauna.

Comparison of the new heatwave and the blob

The key question is how long a new heatwave can last. This also depends on the impact on the marine ecosystem. In any case, there are already shifts in this direction. For example, after some data, migration routes and the population of sea lions begin to decline. The number of crabs and molluscs also decreased. And these are the first links in the food chain. So the extinction of crabs and molluscs can become a real environmental catastrophe. We often write articles on environmental issues, so subscribe to our telegram channel so you do not miss a thing.

This is interesting: Scientists have calculated how much humanity has polluted the oceans.

But what can be done? Currently, the scientists have no clear answer. On the one hand, people have already experienced something similar during the Blob Heatwave, but all of the measures that can now be applied are aimed at treating the "symptoms" rather than the "disease" itself. Environmentalists have already launched a large-scale campaign to save a number of marine animals and destroy toxic algae so that the situation does not start five years ago. Otherwise, one can only hope that the heat wave disappears and the local flora and fauna normalizes again.
