Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…
Climate is changing as humans put more and more greenhouse gases into the atmosphere. With CO2 levels today around 400ppm, we are clearly committed to far more climate change, both in the near term, and well beyond our children’s future. A key question is how that change will occur. Abrupt climate changes are those that…
Published 3rd December 2013: National Research Council Abrupt Impacts of Climate Change: Anticipating Surprises | Release URL Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some…
