Rising levels of carbon dioxide in the atmosphere could increase ocean acidity levels by 150% by the year 2100, which would have catastrophic effects on the planet’s ecosystems, a new report shows.
The study, conducted jointly by several United Nations (UN) sub-organizations, was prepared by scholars for the UN Climate Change Conference – to be held this June in Rio de Janeiro – in order to educate the global community about the vital need to protect the planet’s oceans from rising carbon-dioxide (CO2) emissions.
Ocean acidity levels have increased by 26% since the beginning of the Industrial Revolution. According to the UN report, even under a business-as-usual scenario, ocean-acidity levels would be destructive enough to dissolve calcium-carbonate phytoplankton and zooplankton species, which serve as a crucial food source in ocean ecosystems.
The impact would be most profound in colder temperate and polar regions, where carbon dioxide is more readily absorbed, wreaking further havoc on already threatened environments.
A grim picture? Perhaps. But the reality could be even worse if steps are not taken to curb greenhouse-gas emissions.
Nonetheless, and as cliche as it may sound, recognizing the problem is the first step in curing it. The good news is that one of the primary focuses of the climate-change conference in Rio will be to take action to mitigate and adapt to – and even reverse – ocean acidification to protect biodiversity and the planet’s ecosystems.
