​​The Science Behind Sea Level Rise: How Past Emissions Will Shape Our Future

Union of Concerned Scientists

Sea levels are rising, and science shows they will continue to rise for generations due to heat-trapping emissions that have already been released. Understanding sea level rise as a long-term, multi-generational problem is essential to comprehending the scale of climate change and the need for bold action now.

Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

In an era when massive heat domes blanket large swaths of continents for days, wildfires burn through areas the size of small countries, and hurricanes regularly push the limits of what we once thought possible, sea level rise can seem like extreme weather’s low-key cousin. Since 1993, sea level has risen by an average rate of 3.1

From Research to Action: The Growing Impact of Attribution Science

Union of Concerned Scientists

By comparing these two data sets, scientists can determine the probability that human activities are responsible for observed changes in temperature, precipitation patterns, sea level rise, and other climate change indicators. Climate source attribution studies can inform strategies to reduce carbon emissions.
