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: Permafrost – A Tipping Time Bomb

Recent research from a team of Russian scientists reports that a 1.5°C rise in global temperature is enough to melt permafrost in Siberia and throughout the Arctic. As permafrost melts it releases greenhouse gases and could likely push climate change across a tipping point beyond human control. This video from the Yale Climate Forum looks at the state of permafrost and the consequences on climate as it melts in an increasingly warming Arctic.

Enviro News Wrap: Carbon Tax Bill Proposed; Drought Continues; DOD Releases Climate Adaptation Roadmap, and more…

The Latest Environmental News HeadlinesGlobalWarmingisReal contributor Anders Hellum-Alexander wraps-up and comments on the climate and environmental news headlines for the past week:

  • The “urban heat bubble” theory explains why urban areas are hotter than their neighboring natural environments. More heat is absorbed when we cover the land in asphalt roads, cement sidewalks and tar roofs and get rid of vegetation and water features. A new concept that is taking hold is called “green roofs,” which involves putting both plants and renewable energy generators (like solar) on our roofs. Imagine a roof that both feeds you, powers your home and reduces the effect of the urban heat bubble.
  • Drought has been a major issue in the US for the last two years and might continue to plague us. With multi-year droughts, record forest fires and huge frequent storms much of the US government budget is being diverted to disaster relief, we are paying the price of altering the natural system. That is just the immediate impact that we are already experiencing, what about the melting of our poles, are you ready for the melting of the Arctic?
  • Senator Barbara Boxer has proposed a Carbon Tax bill in the US Senate. Republicans have always prided themselves with being financially responsible during the campaign season, now they can follow through with that rhetoric and get behind a market-based solution to climate change. Of course, they will first have to admit that climate change is real and human caused.
  • The US military has been ahead of the game on many technologies, and right now they are pushing forward aggressively on clean energy and adaption to the effects and threats of climate change. The Department of Defense has just publish a Climate Change Adaptation Roadmap.
  • Scientists released research last week warning the a 1.5 degree C rise in global temperature is enough to melt the Siberian permafrost; and likely much of the rest of the permafrost throughout the rest of the northern latitudes. The melting permafrost may push the climate system past a tipping point.  This means that if a 2 degree C global temperature increase is too much, and 1.5 degrees C is enough to melt permafrost that will add another .5 degrees C to global warming then we are closer to the point of no return then we think. I personally think runaway climate change is already ensured, adaption should be our primary focus with prevention as a side effect of adaption. Read More→

Video Friday: Cryosphere – a Film by Kurtis Hough

“A haunting wailing cry to stop the melting of a glacier”

Kurtis Hough is an independent filmaker and visual artist. In collaboration with Colin Stetson and Dan Wood, Hough created Cryosphere - a film evoking evoking the death throes of an Alaskan glacier.
