 There has been a dramatic rise in methane levels since the end of July 2013. The image below pictures methane levels above 1950 ppb on the Northern Hemisphere from 12 p.m. August 9, 2013, to 12 a.m. August 10, 2013.

Quite suddenly, readings above 1950 ppb have become commonplace since July 31, 2013.

The chart below illustrates the dramatic jump in methane levels that occurred since July 31, 2013. The chart shows the area (square km) with methane readings over 1950 ppb for selected layers, over the period from July 24, 2013, to August 9, 2013. The chart further below shows that peak methane levels have increased dramatically.
Particularly worrying are high levels of methane over the Arctic Ocean, such as on the image below showing methane levels over 1950 ppb in yellow for selected layers on August 5, 2013 (a.m.).

Methane levels are also very high on the Southern Hemisphere, as illustrated by the image below on the right. High readings have featured over the heights of Antarctica for quite some time, but the high levels of methane over the oceans on the Southern Hemisphere have only shown up recently. They could be caused by one or more methane hydrates getting destabilized in the ocean between Antarctica and South America.

  1. Hello Sam,
    I am repeating what i have just said that although Methane levels are rising, 1950 parts per billion is only a little higher than levels until recently, there will be something to orry about if they continue rising rapidly and hit 2000 parts ber billion fairly widely and peaks in excess of 2,500 parts. I am sceptical that this will happen in the next few weeks but I would not rule it out. The situation needs very careful watching.

    Thank you fro all you do.

  2. Dear Sam Carana.

    Climate action strategy is about advertising, finance, a work force and a coordinating infrastructure, all of which is immediately needed because it is time to paint an equatorial tarmac area equivalent to the surface area of ice and snow lost in the last fifty years with solar reflective paint.

    Though considered too simplistic by some, Einstein would approve – the simple and straightforward is best.

    This response is also non-hazardous and reversible. James Lovelock shows us why it is relevant – geo-engineering our daisyworld so everything cools and with the least amount of cost.

    Restoring reflectivity and shading to 1960 levels may also need some ice shelf and mountain glacier solar assisted shading frames
    to prevent repeats of the recent Himalayan flooding, and even stratosphere reflectors in the form of free floating and retrievable hydrogen frames.

    It may also need solar clad pylons incorporating ambient CO2 extractors for the dual purpose of reducing tropospheric concentrations and increasing tree growth in enclosed nurseries.

    Climate technologies, which are non-domestic, also includes seabed and sea surface and melting permafrost methane capture frames.

    But the UNFCCC needs to set up a UN Climate Technology Program this year, and activate the GCF collection worldwide immediately.

    Combined with the tarmac painting and massive tree planting by people who would benefit from paid work, the poorest people presently living in slums and refugee camps, and also making it easy for the wealthy enough to donate to the Fund, that is in banks and post offices worldwide, will result in the now lost 3 million square kilometers of ice and snow in the Northern Hemisphere being restored, and the sea ice accumulating as it used to do.

    Please forward this information to your colleagues, and if suitable constitute it as an article, but please do not credit the ideas to me because, among others, Wangari Maathai of the Greenbelt Movement is the instigator.

    Thank you.


  3. Thanks John, methane levels have meanwhile come down from the jump in early August, but they’re still some 10 ppb higher than they were in July, as discussed at the post Methane Jump.

    Thanks Rosemary, these points should all be considered. Many ways to reduce the methane threat are included in the climate plan that I advocate and are also discussed in posts at the geo-engineering blog.
