Coastal sea level rise with warming above 2 °C

Rapid accumulation of committed sea-level rise from global warming.

As carbon emissions and scientific research have accumulated over recent years, climate scientists have come to see global climate change as an increasingly urgent threat (1, 2). In PNAS, Levermann et al. (3) provide a powerful new indicator of danger. When their findings on the long-term sensitivity of global sea level to global warming (∼2.3 m/°C) are put in the context of recent research on ...

How much more global warming and sea level rise?

Two global coupled climate models show that even if the concentrations of greenhouse gases in the atmosphere had been stabilized in the year 2000, we are already committed to further global warming of about another half degree and an additional 320% sea level rise caused by thermal expansion by the end of the 21st century. Projected weakening of the meridional overturning circulation in the Nor...

New Perspective on Global Warming & Sea Level Rise: Modest Future Rise with Reduced Threat

Sea Level Rise (SLR) in response to the present and future warming of the earth’s surface is probably the most contentious issue being debated at present. This brief commentary surveys the most recent literature on ongoing SLR and on the major factors contributing to future rise. It is concluded that the best guess value of SLR for the next 100 years is a relatively modest 23 cm +/− 5 cm which ...

Coastal Geomorphic Responses to Sea Level Rise: Galveston Bay, Texas

Sea level rise and South Florida coastal forests

Coastal ecosystems lie at the forefront of sea level rise. We posit that before the onset of actual inundation, sea level rise will influence the species composition of coastal hardwood hammocks and buttonwood (Conocarpus erectus L.) forests of the Everglades National Park based on tolerance to drought and salinity. Precipitation is the major water source in coastal hammocks and is stored in th...
