Safety Cannot Be Guaranteed

Already when the Paris COP21 was being negotiated some scientists were stating that reaching a 1.5C increase in temperature past pre-Industrial times was not viable.

Professor Kevin Anderson begins talking 31/2 minutes into film. Prior to becoming a climate sciencist, he worked as an engineer on oil rigs. He has also done some studies in economics which he describes as being akin to astrology.

Professor Anderson argues that energy use in areas other than from power stations has largely been ignored. Without mitigating against the release of greenhouse gases temperatures of 2C or 3C increase can be expected. Rather than be focused on temperature, Professor Anderson states we need to be concerned about the emissions budget, CO2 can take hundreds of years to be dissipated.

The longer that it takes to mitigate against emissions the greater the effort will be needed to mitigate against greenhouse gases already emitted. Professor Anderson states very clearly that while there is much discussion in relation to mitigation, there is no mechanism operating at present.

The IPCC has been meeting in South Korea to produce a Report on the current state of global climate to be published shortlyor.   The first sentence an article in The Washington Post states .. ”

A much-awaited report from the U.N.’s top climate science panel will show an enormous gap between where we are and where we need to be to prevent dangerous levels of warming.”

The article agrees with the summation provided by Professor Anderson that technologies are not available to mitigate emissions being voided ..

“An early draft (leaked and published by the website Climate Home News) suggests that future scenarios of a 1.5 C warming limit would require the massive deployment of technologies to remove carbon dioxide from the air and bury it below the ground. Such technologies do not exist at anything close to the scale that would be required.”

As stated very recently by the Secretary General of the UN, António Guterres; we have till 2020 t0 make an extremely concerted effort to stop a runaway climate. 

Scott Morrison needs to get his act together in relation to climate change, and Labor need to improve theirs. There is no room for coal mines such as in the Carmichael Basin or extensions of coal mines or fracking generally.

    Meanwhile in the land of nod, an ABC article on inundation by the sea on the NW


    while, just down the road, a few Liberal stalwarts vote to back out of the Paris Agreement


    When is this older generation of ideologues going to step aside for the following generations? They’ll be dead and gone when others will have to pay the price of their ignorance.

    I offer hereunder my views in response to the comment above that “future scenarios of a 1.5 C warming limit would require the massive deployment of technologies to remove carbon dioxide from the air and bury it below the ground. Such technologies do not exist at anything close to the scale that would be required” …

    In addition to “massive deployment of technology” I suggest using Nature as well, and perhaps mostly. How?

    Australia has a mind-numbing area of unused ground in its so called “desert” regions. This region provides an enormous flat interface between the earth and the air. It’s at this interface that plants can grow, and one which I currently perceive needs only the application of water to grow anything. From whence cometh that water?

    I suggest that we create the growing conditions wherein Nature can take over and deliver it.

    How? For a start, by the aerial sowing of annual or bi-annual applications of the seeds of appropriate plant cover that can grow under the the prevailing conditions, and spreads laterally using what Nature provides at each layered step.

    I could initially suggest a fast growing plant which is whitish and which can reflect insolation well. That will keep the earth cooler which, given the enormous treated area, will initiate a minor but beneficial change in the climate of the treated region.

    We could then seed that cooler area with a layer of another plant that normally cannot grow there, but can do so in the prevailing cooler temperatures. This might only be a degree or two, but as with Climate Change, even one degree can have huge significance. That second layer could have the nutritious benefits of the used elements of the first.

    Repetitions of this layering process might eventually produce such an improvement in climatic conditions that the “desert” classification no longer applies, while carbon is perennially extracted naturally from the air on a huge scale.

    I imagine that we could rely on the winds for an improved delivery of rain which will enhance the whole closed-loop system to make it self-sustaining indefinitely.

    Do any readers know the findings of any investigation into the viability of the above concept?
