Ocean warming impact on PH: To know the future, look at the past
INQUIRER.netApr 20, 2023
In a recent international multidisciplinary study published in the journal Earth System Science Data, scientists said the world's oceans have absorbed about 89% of the planetary warming in the last 49 years.
The study finds the Earth's Energy Imbalance — generated by human-induced climate change — has risen by nearly 50% between 2006 and 2020 in comparison to the amount accumulated over the last half of a decade.
The study adds to the huge body of evidence that, unless more is done to curb our greenhouse gas emissions, increasing ocean temperatures could cause marine heat waves, a higher risk of extreme weather, and ocean acidification. The ocean has long taken the brunt of the impacts of human-made global warming. For too long, it has been largely absent from global policy conversations on climate change. Since the clock is ticking, now is the time to act and turn the tide.
Such studies need to be taken with more than a few grains of sea salt. Life in the ocean is complex; we don't know much about marine life and changing conditions. Moreover, we must remember that species are resilient and have their own ways of adapting. Besides, modern-day doomsayers have predicted climate and environmental disasters for decades. None of the apocalyptic predictions have come true so far; why would this time be any different?
There's a 50% chance that sea levels will rise by at least 578mm by 2100, according to the Metaculus prediction community.
