Oceans are sucking up increased carbon emissions, raising fears acidification could lead to marine life extinctions BY: JILLIAN KESTLER DAMOURS, Aljazeera
As the effects of global climate change continue to be felt throughout the world's ecosystems, scientists say greenhouse gases are causing rapid changes that may irreversibly alter the composition of the Earth's oceans.
It is estimated oceans absorb up to 30 percent of global carbon dioxide (CO2) emissions, helping to offset the overall warming of the planet. But the amount of CO2 being pumped into the atmosphere since the Industrial Revolution has skyrocketed, saturating oceans and boosting acidification.
Burgeoning ocean acidification raises the spectre of extinctions of coral, algae and shellfish - key cogs in the global food chain - with far reaching consequences for the planet's inhabitants.
