22 January 2013 — In this provocative article, Michael Mobbs is… provocative… as usual. He says the urgent task now is to remove existing pollution from the Earth’s atmosphere, and that without doing so efforts to minimise future pollution are futile.
The real climate deniers are greenies, “sustainable” designers, companies, engineers, builders and policy-makers.
One may speak for something but by actions deny it – and their actions deny climate change.
They say they accept the science that shows human cultures have increased the temperature of Earth. In response, they promote “green” buildings, codes, projects, electric cars and bikes, and things that, they say, will cut future pollution. But these same folk say or do nothing to take existing pollution out of Earth’s air.
Yet it’s existing pollution that has broken Earth’s climate.
In 2007 the UN’s 2000 scientists agreed unless we get rid of existing pollution our Earth will get hotter by more than two degrees. So far it’s heated the planet by one degree. We’ll get that second degree by 2020 or 2030 (1), (2), (3).
Thus, soon we’ll endure more extreme versions of what the first degree has already cooked up for us – increasingly damaging storms, fires, crop failures, droughts, and premature human, insect and vegetation deaths.
The cut off date for reducing existing pollution is now – it was “now” in 2007, the scientists said.
To get a sense of the mountain range of carbon we have to get back from the air and put into our land masses consider this:
- A report from carbon advisory firm, RepuTex, commissioned by WWF and published on 20 January 2014 found that carbon farming in Australia could take out 100 million tonnes of carbon pollution by 2020
- There is two trillion tonnes of carbon pollution in Earth’s air
Last month I took a “helicopter view” of media articles, Twitter, Facebook and internet magazines. All but one of the thousand or so articles spoke of projects or plans to reduce future pollution. They cited trends showing a decline in energy use, carbon trading in China, declining car numbers, trends of increase in public transport, growing numbers of solar panels, reducing costs of renewable energy devices, new sustainable buildings, and so on.
All worthwhile. Clap.
Yes – some new buildings and projects that sustainably use energy, water, sewage and provide transport, food and materials inspire me. We must do them.
But if your goal is to sustain our cultures and Earth, and that’s all you do, then those projects are all beside the point – claptrap.
Let’s be clear. We must do more than slow or stop future pollution. There is so much pollution up there now that stopping future pollution is no longer enough to fix our broken climate. Now, we have to both remove existing pollution and stop future pollution.
Trends, actions or projects to achieve more efficient resource use take not one existing polluting molecule out of Earth’s air.
If all the coal power stations, trucks, cars and bikes in the world were immediately replaced by “clean” ones or all cities were got around in by citizens on public transport they would not take any existing pollution from our air.
They only reduce the rate of new pollution going into the air. Projects to reduce future pollution just defer the end of our cultures by a few decades.
Surely this simple fact has to be confronted honestly by any viable campaign to fix our broken climate?
Is this lack of interest in existing pollution loose thinking of the type we find in people who march in step with the majority? My guess is this thinking is mostly coming from people who have recently discovered that breaking our climate with air pollution will change life as they know it. They have not known weather longer than, say, two or three decades and don’t know what it was like before then. They have “shifting baseline syndrome” (4).
Whatever, let’s be clear. Not one human alive or dead has saved a planet. We’re all on planet-saving training wheels and we’ve fallen off our bike. If we’re to cool Earth we need to kick off our trainers and get out the hot stuff that’s up there now.
Here are projects that can take out existing pollution:
- Commercially-driven, unsubsidised industrial projects that extract carbon from Earth’s air to make things – for example the carbon in air used to make chairs and packaging, a process developed by US business Newlight Technologies
- Carbon farming – growing new soil and vegetation to take carbon out of Earth’s atmosphere
- Vegetation and tree planting – these take out carbon pollution
- Composting – some systems can take out existing pollution
- Local food growing and buying – supports farming, which takes out existing pollution
- Removing or by-passing dam walls and letting rivers run free again – this restores fish populations and vegetation and strengthens the natural recycling of carbon; about 80 per cent of the fish we eat spend key moments of their life in and around estuaries or otherwise depending on them, and, generally, a new dam more than halves some fish populations
- Sealing and closing up coal mines – stops existing and new pollution
- Walking, throwing yourself into ocean pools, laughing and music are essential; they suck existing pollution out of the mind and heart (5)
By growing soil a farmer takes carbon out of Earth’s air.
Sustainability checklists, sustainable buildings, public transport, electric cars and bikes, water and energy efficient appliances, government policies, environmental laws and engineering and design practices were relevant when Earth could cope with more air pollution, but she can’t cope now.
If we’re to sustain her, Earth needs us to reduce existing pollution each day from today ’til we’ve got the two degrees worth of pollution out of her air.
The days of it being okay only to do projects that cut future pollution were gone when 2000 UN scientists told us so some six years ago.

(2) “The average global warming is now 0.8°C over the past century, with recent warming growing at 0.2•C per decade. If continued such a trend will lead to a temperature rise of approximately 3°C by the end of this century (relative to pre-industrial temperatures). Climate models also suggest that this ‘business as usual’ trend will produce global warming of around 3°C by the end of this century. This would be the highest global temperature rise recorded in recent palaeoclimate history.
Greenhouse Gas Concentration
“Carbon dioxide emissions growth is accelerating. The growth rate is increasing from 1.1 per cent per year for 1990-1999 to over three per cent per year for 2000-2004. This recent high growth rate exceeds that in the most fossil fuel intensive emissions scenarios used by the IPCC… A major concern with this increasing concentration of greenhouse gases is how it translates into ‘dangerous climate change’. The IPCC (2007) assessment suggests that this must be at or below 450 parts per million CO2-equivalent, since this will lead to a 2°C (median value) increase in global average surface temperatures above pre-industrial times. This level of change is accepted by the European Union as the limit beyond which there will be sufficient adverse impacts on the Earth’s biogeophysical systems, animals and plants to constitute ‘dangerous’ change.
“We are already at this 450 ppm CO2-eq level. The IPCC reports that the total carbon dioxide equivalent concentration (CO2-eq) of all long-lived greenhouse gases is now about 455 ppm CO2-eq (range: 433-477 ppm CO2-eq). However, the immediate warming effect is reduced by atmospheric aerosols and other air pollutants, which result in an effective 311-435 ppm CO2-eq concentration. But as the cooling effect of the aerosols declines, due to measures to avoid urban air pollution and acid rain, the warming effect remains. And there are no signs so far of any reduction in the growth of emissions in the long-lived greenhouse gases.”

(4) Landscape, memory and what we see and don’t see: A colleague, Stefanie Pillora, has observed in her working notes for her PhD about natural resources: “British journalist George Monbiot in his book Feral writes about the way generations perceive the state of the ecosystems they encountered in their childhood as normal. He gives the example of the treeless hills of England and Wales being promoted as wilderness as the memory of the forests that covered that land, and the animals that lived there, had been forgotten. Monbiot calls this forgetting ‘shifting baseline syndrome’, which was first identified by the fisheries scientist Daniel Pauly.” https://www.acelg.org.au/shifting-baseline-syndrome

“Based on material in the IPCC Second Assessment Report (IPCC WGI, WGII and WGIII, 19964), this Technical Paper expands and clarifies the scientific and technical issues relevant to interpreting the objective of the United Nations Framework Convention on Climate Change (UN/FCCC) as stated in Article 2 (United Nations, 1992):
“The ultimate objective of this Convention and any related legal instruments that the Conference of the Parties may adopt is to achieve, in accordance with the relevant provisions of the Convention, stabilisation of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Such a level should be achieved within a time frame sufficient to allow ecosystems to adapt naturally to climate change, to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.”
“Article 2 requires stabilisation of greenhouse gas concentrations. Here we emphasise CO2, but we also consider several other gases to illustrate the uncertainties associated with a more general multi-gas stabilisation objective and to highlight what can be said with some confidence.
“The clear historical relationship between CO2 emissions and changing atmospheric concentrations, as well as our considerable knowledge of the carbon cycle, implies that continued fossil fuel, cement production, and land-use related emissions of CO2 at historical, present or higher rates in the future will increase atmospheric concentrations of this greenhouse gas. Understanding how CO2 concentrations change in the future requires quantification of the relationship between CO2 emissions and atmospheric concentration using models of the carbon cycle.”
