With COP28, the 28th annual United Nations climate meeting, coming to a close in Dubai, climate science has been in the international spotlight for the last two weeks. At the ǧ����Ƶ, our scientists study how climate change is impacting ecosystems and organisms in Cape Cod and beyond. Check out the stories below to catch up on some climate research from MBL scientists.

Decades-Long Arctic Rivers Study Conceived at MBL Reveals Widespread Change

This study examined a nearly 20-year record of water chemistry collected from the six largest rivers that drain to the Arctic Ocean, and signaled widespread effects of climate change in the North.

Most of the World’s Salt Marshes Could Succumb to Sea Level Rise by Turn of Century

Salt marshes are some of the most biologically productive ecosystems on Earth. According to research from the ǧ����Ƶ Ecosystems Center, more than 90 percent of the world’s salt marshes are likely to be underwater by 2100.

Framework Helps Local Planners Prepare for Climate Pressures on Food, Energy & Water Systems

MBL scientists and colleagues released a toolkit in early 2023 to help the U.S. Midwest and Northeast prepare for climate-induced strains on critical civic resources.

As Temps Rise, Low Marsh Emits More Carbon Gas than High Marsh

Salt marshes are a well-known carbon sink and can aid in carbon sequestration efforts. But they are also dynamic ecosystems that change with the seasons and tides. Understanding these dynamic systems can can inform climate change mitigation efforts

Gauging Water Loss from Northern Peatlands, a Likely Accelerant of Climate Change

More carbon is stored in the forests, peatlands, and lakes of the high northern (boreal) latitudes than is currently in the atmosphere. Therefore, understanding how the boreal latitudes, which include Canada and Alaska, respond to global warming is vital for predicting its trajectory.

Leaving Microbes Out of Climate Change Dialogue has Major Consequences, Experts Warn

In 2019, more than 30 microbiologists from institutions in 9 countries, including the ǧ����Ƶ, issued a warning to humanity that omitting microbes – the support system of the biosphere – from  the climate change equation would have major negative consequences.

Salt Marshes' Capacity to Store Carbon may be Threatened by Nitrogen Pollution

This study led by the ǧ����Ƶ Ecosystems Center indicates that a common pollutant of coastal waters, nitrate, stimulates the decomposition of organic matter in salt marsh sediments that normally would have remained stable over long periods of time. This increase in decomposition, which releases CO₂, could alter the capacity of salt marshes to sequester carbon over the long term.
