More than 115 cases of eye damage reported in Ontario after solar eclipse
More than 115 people who viewed the solar eclipse in Ontario earlier this month experienced eye damage after the event, according to eye doctors in the province.
The world's coral reefs are under attack by climate change and more will disappear if oceans keep warming, according to a report released Tuesday.
The study by the Global Coral Reef Monitoring Network (GCRMN), a UN-supported global data network, showed that 14 per cent of the world's coral on reefs was already lost between 2009 and 2018, equal to about 11,700 square kilometres, an area 2.5 times the size of Grand Canyon National Park.
Corals face an "existential crisis," scientists said, as sea surface temperatures rise. The report spanned data for 40 years, 73 countries and 12,000 sites.
Sharp spikes in warming are particularly damaging, a phenomenon scientists say is linked to human-caused climate change.
The study looked at 10 coral reef-bearing regions around the world and found that loss was mainly attributed to coral bleaching, which happens when corals, under stress from warmer water, expel the colorful algae living in their tissues, making them turn white.
One severe bleaching event in 1998 alone killed 8 per cent of the world's corals, the study said.
The hardest hit areas are South Asia, Australia, the Pacific, East Asia, the Western Indian Ocean, the Gulf and Gulf of Oman.
Overfishing, unsustainable coastal development and declining water quality are other factors battering the reefs.
"There are clearly unsettling trends toward coral loss, and we can expect these to continue as warming persists," said Paul Hardisty, chief executive of the Australian Institute of Marine Science, in a statement shared by the United Nations.
The global ocean has warmed faster over the past century than since the end of the last deglacial transition, around 11,000 years ago, the Intergovernmental Panel on Climate Change (IPCC) said in a landmark report in August.
While coral reefs cover less than 1 per cent of the ocean floor, they support more than 25 per cent of marine biodiversity, including turtles, fish and lobsters, which fuel global fishing industries.
The reefs are responsible for an estimated US$2.7 trillion annually in goods and services, including tourism, the report said.
Scientists did find, however, there was about a 2 per cent regain among coral reefs 2019, showing they can be resilient when given respite from the siege of factors working against them.
If pressure is relieved on the coral reefs, they could flourish again within a decade to pre-1998 levels, the report said.
Recent efforts to support coral reefs include a mitigation project off the coast of Caribbean nation Antigua and Barbuda called Ocean-Shot, which uses technology that mimics the design and shape of natural reefs to provide opportunities for colonization by corals and other marine life.
