Arctic Ocean Rapidly Acidifying

Arctic oceans acidification is increasing rapidly due to several factors including declining sea ice and freshwater flows. After three years of ongoing research by an international team of scientists, a study commissioned by the Arctic Monitoring and Assessment Programme for a first-ever comprehensive assessment of Arctic Ocean acidification was presented last week at a meeting of Arctic Council Ministers in Bergen, Norway.

The research show that the cold waters of the Arctic sea are more vulnerable to acidification. Cold water more readily absorbs CO2 and combined with the precipitous drop in summer sea ice extent, thus exposing more open water, northern oceans are rapidly acidifying.

“The sea ice has been a lid on the Arctic, so the loss of ice is allowing fast uptake of CO2,” said Richard Bellerby of the Norwegian Institute for Water Research, chairman of the report.

Video Friday: Evidence for Climate Change Before Al Gore, Computer Models, or the IPCC

Today’s video from Potholer54 (a.k.a. Peter Sinclair) dispels the myth that evidence for climate change is based solely on computer models, or some sort of hoax designed to make Al Gore rich, or a massive conspiracy by a cabal of power-hungry, grant-seeking climate scientists operating under the aegis of the IPCC. It’s stuff your great grandfather knew.  

Statement by UNFCCC Executive Secretary on crossing of 400 ppm CO2 Threshold

Press release from the United Nations Framework Convention on Climate Change

(Bonn, 13 May 2013):

Reacting to the fact that the global concentration of heat-trapping carbon dioxide in the atmosphere last week passed the 400 parts per million mark, the Executive Secretary of the UN Framework Convention on Climate Change Christiana Figueres on Monday called for a greatly stepped-up response to climate change by all parts of society:

“With 400 ppm CO2 in the atmosphere, we have crossed an historic threshold and entered a new danger zone. The world must wake up and take note of what this means for human security, human welfare and economic development. In the face of clear and present danger, we need a policy response which truly rises to the challenge. We still have a chance to stave off the worst effects of climate change, but this will require a greatly stepped-up response across all three central pillars of action: action by the international community, by government at all levels, and by business and finance.”

Governments will be meeting 3 – 14 June in Bonn for the next round of climate change talks under the umbrella of the UNFCCC. A central focus of the talks will be negotiations to build a new global climate agreement and to drive greater immediate climate action.

Resiliency Index Will Assess Climate Risks for Cities

New resiliency index announced with C40 Cities at the Clinton Global InitiativeWorking under the umbrella of C40 Cities, an international collaborative  of cities working to assess and reduce their climate risk impacts, New York mayor Michael Bloomberg and former president Bill Clinton are launching a climate change adaptation and resiliency measurement program aimed at identifying the cities most at risk. Clinton and Bloomberg announced the initiative on Monday at the midyear meeting of the Clinton Global Initiative.

The new effort will work alongside a separate and ongoing c40 initiative that now accounts for the greenhouse gas emission for 75 percent of C40 member cities. The new program adds a “resiliency yardstick” to help governments and insurers assess and plan for future damage and what specific areas and cities are most vulnerable to the worst damage.

As we’ve written about in past articles, cities are at the nexus of change and effective action; planning and implementing strategies at the regional and municipal level can be the most effective means in many cases of protecting citizens from climate disruption and preparing for the future.
