Humans currently release about 70 million tons of carbon dioxide every day into the atmosphere and about 20 million tons is being absorbed regularly by the oceans, causing the pH to drop. Chris Sabine describes current and projected future impacts of this acidification on marine ecology.
Climate scientist Michael MacCracken explores some of the scientific, legal, and ethical implications of "geo-engineering" options that have been proposed by some people to address global climate change.
The arrival of Hurricane Isabel in 2003 flooded the retirement home of a Chesapeake Bay couple. With sea level around the Chesapeake Bay rising faster than the global average, how are coastal residents planning for change?
Rhode Island's coasts are already feeling the impacts of rising seas. The Rhode Island Coastal Resources Management Council and Rhode Island Sea Grant are working with the legislature to explicitly address sea level rise and climate change in the state's building code.
National Academies release two reports on climate intervention
February 13, 2015
Climate interventions, aka "geoengineering," refers to deliberate, large-scale manipulation of Earth’s climate intended to counteract human-caused climate change. The National Academies Press has released two reports that assess the potential impacts, benefits, and costs of two different proposed classes of climate intervention: carbon dioxide removal and reflecting sunlight. Neither of these types of interventions should take priority over mitigation and adaptation, the reports stress.
Planning for Post-Disaster Recovery: Next Generation
January 15, 2015
The American Planning Association's Hazards Planning Center worked with FEMA to develop Planning for Post-Disaster Recovery: Next Generation. This updated manual offers a no-nonsense explanation of the benefits and limitations of planning for unpredictable events.
The New Jersey FloodMapper is a user-friendly visualization tool for local communities who need to make decisions concerning flooding hazards and sea level rise. This tool should be used to promote enhanced preparedness and land use planning decisions with considerations for possible future conditions.
