Global Warming Causes Rising Sea-Levels and Boston Flooding

Published on Dec 5, 2006

Animations shows flooding in Boston that would result from a 100-year coastal storm surge with sea level rise of 0.60 meters (approximately 2 feet). Higher relative sea level will add to the base elevation of any storm surge, giving it more power to overtop both natural and constructed protection. Find out more at http://www.net.org/warming

Will sea level rise drown our coastal cities?

Sea level rise could submerge land currently home to up to 760 million people worldwide if global temperatures rise 4 degrees celsius by the year 2100. So what are cities and city planners going to do to minimize the potential devastation? Resources on this topic: Brecht, H., Dasgupta, S., Laplante, B., Murray, S., & Wheeler, D. (2012).

US cities under 25 feet of water

Published on Sep 5, 2015

Coastal cities could see a rise in sea levels by as much as 4 ft by the end of the century. To help put a visual to the number, artist Nickolay Lamm created this series of simulations of US city landmarks as affected by sea levels rising 5, 12 and 25 feet. Using Climate Central’s sea level rise maps, Lamm imagines recognizable locales such as Venice Beach CA, Miami Beach FL, and Boston Harbor with catastrophic flooding. Produced by Rob Ludacer

What will Boston look like by the year 2100? It depends on how much CO2 is emitted into the atmosphere. Watch as sea-level rise overtakes Boston’s shorelines this century. For a neat graphic showing CO2 and temperature: http://openclimatedata.net/climate-sp…

Arctic ice melt could trigger uncontrollable climate change at global level

Climate Change News
Published on Nov 4, 2017

Scientists warn increasingly rapid melting could trigger polar ‘tipping points’ with catastrophic consequences felt as far away as the Indian Ocean
Arctic scientists have warned that the increasingly rapid melting of the ice cap risks triggering 19 “tipping points” in the region that could have catastrophic consequences around the globe.

The Arctic Resilience Report found that the effects of Arctic warming could be felt as far away as the Indian Ocean, in a stark warning that changes in the region could cause uncontrollable climate change at a global level.

Temperatures in the Arctic are currently about 20C above what would be expected for the time of year, which scientists describe as “off the charts”. Sea ice is at the lowest extent ever recorded for the time of year.

“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report. “[These developments] also make the potential for triggering [tipping points] and feedback loops much larger.”

Climate tipping points occur when a natural system, such as the polar ice cap, undergoes sudden or overwhelming change that has a profound effect on surrounding ecosystems, often irreversible.

In the Arctic, the tipping points identified in the new report published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock-on effects on ocean ecosystems around the globe.

The research, compiled by 11 organisations including the Arctic Council and six universities, comes at a critical time, not only because of the current Arctic temperature rises but in political terms.


Arctic Resilience Report

Resilience; ARR; Arctic Resilience Report The Arctic Resilience Assessment (ARA) is an Arctic Council project led by the Stockholm Environment Institute and the Stockholm Resilience Centre. It builds on collaboration with Arctic countries and Indigenous Peoples in the region, as well as several Arctic scientific organizations. The ARA (previously Arctic Resilience Report) was approved as an Arctic Council project at the Senior Arctic Officials meeting in November 2011. The ARA was initiated by the Swedish Ministry of the Environment as a priority for the Swedish Chairmanship of the Arctic Council (May 2011 to May 2013) and is being delivered under the US Chairmanship of the Arctic Council.
