Arctic News: Methane levels as high as 2845ppb
http://arctic-news.blogspot.com/2015/04/methane-levels-as-high-as-2845ppb.html
Sunday, April 26, 2015. Methane levels as high as 2845ppb. Methane levels as high as 2845 parts per billion (ppb) were recorded on April 25, 2015, as illustrated by the image below. This is an extremely high peak. The average daily peak in 2015 until May 1 was 2371 ppb, while the highest daily mean ranged from 1807 ppb (January 10) to 1829 ppb (April 22). Daily peaks and daily highest mean levels in 2015 are shown on the image below. The table below shows the altitude equivalents in mb (millibar) and feet.

Arctic News: Climate Plan
http://arctic-news.blogspot.com/p/plan.html
The Climate Plan describes the danger of runaway warming and constitutes a plan of action that is comprehensive and effective enough to stand a chance of reducing the threat of runaway warming, with. Obvious benefits for the environment and for species threatened with extiction. Please support, follow and discuss the Climate Plan at facebook.com/ClimatePlan. An Effective and Comprehensive Climate Plan. Feebates typically are the most effective way to achieve the necessary shifts, and they generally are b...

Arctic News: The Mechanism
http://arctic-news.blogspot.com/2015/02/the-mechanism.html
Saturday, February 28, 2015. What is the mechanism behind accelerated warming of the Arctic Ocean, huge abrupt methane eruptions from the seafloor of the Arctic Ocean and skyrocketing temperatures? 1 Potential for Methane Release in Arctic. Natalia Shakhova et al. in 2010 estimated the accumulated potential for the East Siberian Arctic Shelf (ESAS) region alone (image on the right) as follows:. Organic carbon in permafrost of about 500 Gt. About 1000 Gt in hydrate deposits. Such methane eruptions are cau...

Arctic News: Ocean Temperature Rise Continues
http://arctic-news.blogspot.com/2014/11/ocean-temperature-rise-continues.html
Thursday, November 20, 2014. Ocean Temperature Rise Continues. Of all the excess heat that results from people's emissions, 93.4% goes into oceans. Accordingly, the temperature of oceans has risen substantially. High methane levels were recorded over the Arctic Ocean in October, as discussed in this earlier post. And were sustained in November, as discussed in this post. Methane levels as high as 2717 ppb were recorded on November 16, 2014, p.m, by the MetOp-1 satellite at 469 mb (i.e. 19,820...Methane l...

Arctic News: Policies
http://arctic-news.blogspot.com/p/policies.html
Two types of feebates can help cut emissions, reduce greenhouse gas levels in the atmosphere and the oceans, and more. From a policy perspective, it's good to implement feebates separately, but their impact doesn't need to be restricted to one area and each feebate may work and achieve benefits in several areas. Feebates, preferably implemented locally, are recommended as the most effective way to reach targets. As discussed at the this page. Agriculture, construction, water and land care feebates. Many ...

Arctic News: Year 2012 set to break all records
http://arctic-news.blogspot.com/2012/08/year-2012-set-to-break-all-records.html
Thursday, August 2, 2012. Year 2012 set to break all records. The image below, edited from the National Snow and Ice Data Center. Shows that Arctic sea ice extent is at a record low for the time of the year. According to measurements by the Institut für Umweltphysik at the University of Bremen. A new historic Arctic sea ice minimum. Was reached on 8 September, 2011. The year 2012 looks set to reach even lower extent. The image below shows a retreat in sea ice area to 3.91533 million km. Ie about 700 km.

Arctic News: It's time to 'Do the math' again
http://arctic-news.blogspot.com/2015/04/its-time-to-do-math-again.html
Thursday, April 23, 2015. It's time to 'Do the math' again. Have we gone mad? Released today explains why contemporary climate change policy-making should be characterised as increasingly delusional. As the deadline approaches for submissions to the Australian government's climate targets process, there is a flurry of submissions and reports from advocacy groups and the Climate Change Authority. A survey of the relevant scientific literature by David Spratt, " Recount: It's time to 'Do the math' again.

Arctic Methane: Links
http://arcticmethane.blogspot.com/p/links.html
Methane releases in the Arctic can lead to abrupt local warming that triggers further methane releases. The amount of methane stored in hydrates is huge and release of even a small part of the methane in hydrates could lead to runaway global warming. This blog features discussions on methane in the Arctic. If you like submit a link that is relevant, please post a comment with details. Arctic methane emergency group.org.

Arctic News: Mackenzie River Warming
http://arctic-news.blogspot.com/2015/05/mackenzie-river-warming.html
Friday, May 15, 2015. On May 12, 2015, a temperature of 80.1°F (or 26.7°C) was recorded in the north of Canada, at a location just north of latitude 63°N. High temperatures in such locations are very worrying, for a number of reasons, including:. They are examples of heatwaves that can increasingly extend far to the north, all the way into the Arctic Ocean, speeding up warming of the Arctic Ocean seabed and threatening to unleash huge methane eruptions. Alaska is hit by high temperatures as well. The...

Arctic News: Two degrees of warming closer than you may think
http://arctic-news.blogspot.com/2015/02/two-degrees-of-warming-closer-than-you-may-think.html
Sunday, February 8, 2015. Two degrees of warming closer than you may think. It has taken a hundred years of human-caused greenhouse emissions to push the global temperature up almost one degree Celsius (1C°), so another degree is still some time away. Right? And there seems to have been a "pause" in warming over the last two decades, so getting to 2C° is going to take a good while, and we may have more time that we thought. Yes? Wrong on both counts. Here's why 2C° could be just 20 years away. NASA's God...
