Ocean acidification in the face of many environmental stressors

Greenhouse gas emissions are acidifying the ocean. The progressive decrease in ocean pH, or ocean acidification, is impacting ecosystems across the globe. Despite our understanding of the severity of ocean acidification’s impacts on individual species, the story is more complicated. We must also consider more broadly how ocean acidification affects ecosystems that are also exposed to a variety of other stressors such as changes in temperature and oxygen, coastal nutrient input, fishing, and ocean commercial transportation. It is critical that future adaptation and mitigation strategies consider how these co-occurring stressors interact with one another.

Will Climate Policies Give Us Cleaner Air?

Clean air is very important to keep people healthy. While most people in the US are fortunate to have reasonably clean air, many people still get sick and die every year from dirty air. Around the world people are worried about the impacts of climate change. There may be a way to reduce the impacts from both air pollution and climate change at once.

Accounting for Greenhouse Gases: Methane in India

How do we know how much heat-trapping greenhouse gas there is in the atmosphere? What about where these greenhouse gases are coming from? Scientists work hard to answer these questions on global, national, and regional levels. Recently, a group of scientists from India, the United Kingdom, Germany, and the United States collaborated to evaluate India’s emissions of the greenhouse gas methane. This blog post explains how greenhouse gas accounting is similar to tracking your bank account. The post then discusses in more detail how the India study was conducted, and why its findings are important.

How much does pollution increase as cities grow?

People worldwide are increasingly living in cities. Urban life has many benefits including economic growth, but large concentrations of people and their activities can lead to increased pollution. A recent study evaluated the trade-offs between pollution and urbanization to see if the economic benefits outweigh the negative health impacts.

Ocean Acidification is in the Spotlight. How Can We Address Its Impacts?

The ocean has become 30% more acidic since the Industrial Revolution. This continuing change in ocean pH, or ocean acidification, will likely impact the economies of coastal communities. The science community must work together with industry, policymakers, other science disciplines, and coastal communities to find practical and applicable solutions to address the environmental impacts of ocean acidification. This integrated approach is known as transdisciplinary science and seeks to understand the interactions among ocean acidification, the ecosystem, and society.

Ocean Acidification Steps into the Spotlight

The ocean absorbs nearly a quarter of the carbon dioxide humans emit. Since the Industrial Revolution the ocean has become 30% more acidic. This change in ocean carbon chemistry, or ocean acidification, has the potential to impact many socioeconomic resources. An increased scientific understanding of these risks has illustrated the need for collaboration across many disciplines to develop realistic solutions to mitigate the rising threat to vital marine resources. Transdisciplinary science will be critical in informing policy to protect our economic interests.
