Humans are losing a crucial natural resource to warming oceans. This resource costs an estimated $2.7 trillion annually and is about to face a catastrophic event.

A crucial ecosystem

Coral Reefs are a crucial maritime ecosystem. According to The New York Times, scientists estimate that they once nurtured at least a quarter of all ocean species.

Food and income

That is why they are also vital sources of food and income for those who depend on the ocean, especially fishing, for survival.

Thousands of communities

Thousands of communities around the basins of the Pacific, Atlantic, and Indian Oceans depend on the coral reefs that cover their coastal areas for income and food.

A catastrophic event

However, these people might face terrible news in the coming weeks. According to NOAA experts, the world's coral reef reserve will face catastrophic bleaching events.

Within weeks

The bleaching event, which researchers predicted through rising ocean temperatures, will come in only a few weeks, experts warned The New York Times.

High ocean temperatures

Corals bleach because the symbiotic algae that give them their color, which they depend on to survive, dies under high water temperatures.

More than half of worldwide coral reefs

NOAA experts told the New York Times that more than half the planet's coral reefs are under high-temperature stress.

The worst bleaching event

It will be the worst bleaching event in history, with 54% of reefs under pressure and rising by 1% each week.

1998

Other worldwide bleachings have happened, and the percentage has kept rising. The first recorded was in 1998, with 20% of coral reefs affected.

2010

In 2010, 35% of the world's coral reefs were under bleaching-level heat stress, a 15% rise from 12 years earlier.

2014-2017

The last bleaching event extended from 2014 to 2017, affecting 56% of all coral reefs.

Recovery

Ecosystems can recover, but only when waters turn cold again fast enough. Fortunately, according to The Washington Post, experts expect that to happen this time, thanks to the La Niña weather event.

Crossed limit

Still, we have already crossed a perilous line. According to the experts cited by The New York Times, most coral reefs will die after the world reaches a temperature of 1.5°C (34.7°F).

Ultimate limit

Those experts believe that all coral reefs will die if we reach the absolute limit of 2°C (35.6°F) set out by the UN and several nations in international agreements.

We are not solving the problem

Still, according to the last UN report on climate change, despite already crossing the 34°F threshold, nations are burning more fossil fuels than ever.
