What was the only thing researchers could find that could cause corals to turn white?

Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching.

What will happen if we don’t save the ocean?

By 2030, half of the world’s oceans will already be suffering from climate change, which will have catastrophic consequences for marine life. Hotter water temperatures mean that there’ll be less oxygen in the water, so many animals won’t be able to live in their current habitats and be forced to migrate.

What is the largest structure ever made by life on Earth?

The Great Barrier Reef is the largest structure ever made by life on Earth.

How many years will the oceans become too warm for coral reefs to survive?

I did this some years ago and came up with the answer that most oceans get too hot for their corals on a yearly basis by 2040-2050.

Does acidification cause coral bleaching?

Greenhouse gas emissions are the main cause of ocean acidification and the increases in sea temperature that cause coral bleaching. Any efforts to reduce emissions will bring benefits both on land and at sea. However, global greenhouse gas emissions have risen steadily in recent years.

How do you know if coral is dying?

Look at the color and shape. Old dead corals will be broken down, and lack a healthy color, and are sometimes covered in algae. Corals that have been bleached from rising ocean temperatures turn white when the symbiotic algae leaves the coral.
