Predict what will happen to the algae and corals if
global warming continues.

If global warming continues the coral reefs may be completely lost by 2100.

When sea temperatures rise, the algae that give coral its bright colours leave their host, causing it to look white, hence the term 'coral bleaching'.

At this rate, rising sea temperatures, acidic water and pollution are proving too much for the reefs to handle. About 70 to 90 per cent of the world's existing coral reefs are predicted to disappear. Once that tipping point is passed, the deterioration of other marine systems may cascade more quickly and irreversibly.
