The Problem
The ocean has protected us from the worst effects of climate change.
From the beginning of industrialization until today, the ocean has absorbed more than 90 percent of the heat from human-caused global warming and about one-third of our carbon emissions. But we are now seeing the devastating effects of that heat and carbon dioxide.
The ocean is too big to ignore. A range of climate impacts—including ocean acidification, sea-level rise and stronger and more frequent hurricanes—are damaging our coastal industries and communities. Moreover, these ocean-climate impacts disproportionately harm communities of color, Indigenous communities, poor communities and others that are historically underserved and underrepresented.
There is more than our own wellbeing at risk—ocean ecosystems and wildlife are also at stake. Coral reefs are dying off and could be eradicated completely by the end of the century; the essential sea ice of the Arctic is disappearing, threatening Arctic animals and ecosystems; and even fish will decline as their populations shrink and move in search of cooler water.
We are in danger of losing what makes the ocean such an important and special place to so many of us, who rely on it for livelihoods, food, recreation and moments of wonder. Although climate action and ocean conservation efforts historically have been separated, we cannot save the ocean without acting on climate change, and we cannot confront the climate crisis without considering the ocean.
The Solution
In order to protect our communities, ocean and planet, we must work to limit global warming within 1.5 degrees Celsius over pre-Industrial temperatures.
This means reducing greenhouse gas pollution—including carbon dioxide emissions, which cause not only warming but also ocean acidification—to net-zero no later than 2050. And, as our society shifts away from fossil fuels and toward clean energy, we must ensure a just transition for impacted communities, workers and cultures.
With diminishing time to address the climate crisis, we need to reduce greenhouse gas pollution across every sector, from electricity and transportation to buildings and agriculture. In this context, it is important to remember that the ocean is not just a victim of climate change but also a key part of the solution. From reducing emissions from shipping and ports to scaling up well-sited offshore renewable energy, we can look to ocean industries to contribute a range of sustainable climate measures.
When oil spills hit the water, we unfortunately already know the devastating impacts. And yet, fossil fuel companies are not only drilling; they’re also leaving their unused, old and dirty oil rigs in our ocean, allowing them to sit and pollute the water and climate. It’s time to hold Big Oil accountable for cleaning up after themselves.
Give today to protect our ocean from the effects of the climate crisis and other threats. Ocean Conservancy is on the front lines of ocean protection, but we can’t do our work without you.
