Great Barrier Reef devastated by coral bleaching |
|---|
|
Long stretches of the famously colourful reef, which is world heritage-listed and one of the country?s top tourist destinations, have turned ?snow-white? following bleaching which began six months ago, according to the resarchers.
Aerial survey of 520 sites across the 1,500-mile stretch of delicate coral reefs in north-east Australia found that the most pristine sections had been facing some of the worst bleaching in recorded history. Scientist in Australia have warned for years that climate change has led to warmer waters which threaten the long-term future of the reef.
Scientists say an underwater heat wave in Reef has led to devastating coral bleaching – the worst in history - which has damaged or killed 95 per cent of the northern reefs. Scientists believe the bleaching was triggered by a temperature spike due to the El Nino weather pattern, which added to already warmer waters caused by climate change. Warmer temperatures can kill the tiny marine algae which are required to maintain the health of coral and give it colour.
The bleaching has affected virtually all species of the reef?s coral.Cloudy weather is believed to have kept temperatures down and prevented heavy damage in the southern parts of the reef. The damage has raised fresh questions about whether UNESCO may list the marine park as ?in danger?. The organisation last year decided not to downgrade the park?s listing but expressed concern about the damage caused by mining and coastal pollution.

This is alarming.In fact the El-Nino has been very inconsistent because of Global Warming.Thanks for sharing this report and drawing our attention towards Coral bleeching. Immediate action must be taken to protect the corals..

The heat, over dissolved carbon dioxide, and ruthless collection by some people that believe coral reefs have magical power,,, except for the last one, it especially comes to me as a sad incorrigible reality that there is not much action that could be done to protect the reef. Actions should have been taken years beforehand. I hope appropriate measures to be enacted to protect what is left at least. :p

The causes of such anomalies in the environment today are a result of the destructive activities we are engaged in. There have been fewer of such anomalies but as the incidence of climate change is increasing day by day, more such event will take place in more parts of the world. I really hope the local authorities act immediately to not only control but also pacify the situation. Since our activities are causing problems in maintaining the equilibrium in the nature, therefore it is our responsibility to correct them. Thanks for the report.

I was also very sad upon reading about Australia's Great Barrier Reef experiencing its worst coral bleaching due to heat stress resulting from high sea temperature. Local authorities must take immediate measures to prevent further harm and take control of the situation.
Our behaviour and attitude towards our natural environment are great determining factors of how much coral bleaching we are going to cause, and how much aquarium life we are going to spare.Thanks for sharing.

Mohit, I feel also concerned about the beautiful coral reef bleaching because of ocean temperature. Abnormal climate such as El Nino is not driven from a very specific factor, but is resulted from the overall environmental destruction. Thus the responsibility for the bleached coral reef also becomes unclear as well. I hope possible preservation be made to keep its beauty, and keep up the good work as well:-)
