1. Stop putting carbon
CONVERSION of energy
Nature Journal October 2009 Climate Crunch Sucking It Up. www.nature.com/news/2009/090429/full/4581094a.htmlCaution is warranted in taking .. values as targets for decision-making.Atmospheric CO2 concentrations are currently at 390 p.p.m.,and even if we could put an end to our emissions now, a sizable fraction of CO2 would remain in the atmosphere for millennia (Nat. Rep. Clim. Change 2, 156–158; 2008). Unless we find a way of sucking CO2 out of the atmosphere (Science 325, 1654–1655; 2009), returning to 350 p.p.m. within a time-frame that is relevant to decision-makers will be well nigh impossible.Targets can all too easily be used to justify continued environmental degradation on the basis that it is within an acceptable range (Nature 461, 447–448; 2009). That's especially true of long-term goals, whose chances of being met can't be measured by present-day behaviour.
Technology. CO2 air extraction.
To have any chance of stopping global warming from increasing, nations must plan to stop the emissions of all long lasting (in the atmosphere) greenhouse gases. This is not impossible, it does not mean the end of civilization (global climate change does). That's because it is just a matter of switching technologies and chemicals to zero carbon and non toxic alternatives that exist already.
We are told that to reduce emissions would be very costly. This is the biggest climate change lie out there and most people have fallen for it.
It would not cost anything. The truth is developing any new technology is a huge economic boost.
The global zero carbon development and re-development would be the greatest economic and employment boost ever.
There is in addition a huge immediate cost saving from stopping the toxic air and water pollution of fossil fuels. The cost to our health and from health treatment is enormous.
Zero Carbon Science to Zero Carbon Response
2. Start taking carbon
out of the atmosphere.
To enable any reduction of today's catastrophic concentration of atmospheric carbon dioxide and the long-term stabilization of atmospheric carbon dioxide, the science of zero carbon emissions demands a total replacement of all fossil fuel energy by clean zero carbon and everlasting energy. In a word conversion of the world's energy supply.
The image from a renewable energy report by the government of Germany some years ago shows that every source of renewable energy can provide more than the world's need of energy. The report calculated renewable energy potential was 3000 times than the energy consumed by the world.
For the past 30 years non-governmental organisations and periodically governments have promoted the conservation of energy, which obviously must happen. Unfortunately during the promotion of evermore the larger fossil fuel energy consuming technologies, energy conversion conservation has made little progress, even though all the methods to do so have been available for a time.
The prevailing approach to reduce carbon emissions is the reduction in carbon intensity, which is an energy conservation relying on energy efficiency approach. But it is impossible to achieve zero carbon no matter how successful we are in improving fossil fuel energy efficiency. What in actual fact has been happening as a result of increasing is that global emissions have increased great carbon intensity. this is because improving carbon intensity has no effect on globalization fossil fuel energy and technologies that use fossil fuel energy.
So we have to have both conservation of energy and conversion of energy.
Forestation - It is generally believed that we can take carbon dioxide out of the atmosphere by planting more forests. Unfortunately for the prevention of global climate catastrophe, this is a temporary solution. The carbon cycle teaches us that the terrestrial carbon cycle involves photosynthesis of green plants taking carbon dioxide out of the atmosphere. Fixing it as carbon for energy use and plant growth (and in the process releasing oxygen to the air). But this is just one half of the carbon cycle - the other half occurs when plants decay and die and then the carbon is returned to the atmosphere as carbon dioxide. Over the long term the carbon is just recycled. Forests do not sink carbon permamently except by becoming fossil carbon (fuels).
In the diagram above left there are two energy sources included that straddle the zero carbon energy and carbon emitting energy divide.
Nuclear energy is one. Nuclear power generation does not emit carbon dioxide as a consequence of energy generation. carbon dioxide aspect of nuclear power is in the construction at the power plant. Although the opposition to nuclear energy in general has blocked their construction, you improve generations of nuclear energy especially small-scale nuclear energy generators emit very much less carbon dioxide in the construction and they are also safer. obviously the idea decommissioning existing nuclear energy plants unless an individual plant is found to be 'I'm safe to operate' makes no sense for mitigating global climate change. The long-running nuclear energy plan stays in operation the less is the carbon footprint of the power plants lifetime. If the nuclear energy plan is taken out of commission on the basis of public attitude and that large amount of energy is replaced by coal-fired energy a large amount of zero carbon energy has been replaced by the highest carbon emitting source of energy. The last word is that there is no risk of nuclear energy generation destroying civilization ending humanity and ending most life on Earth. Continuing with coal-fired generation will most certainly do that.
Biomass energy is the other energy source in the diagram straddling zero carbon, zero emitting.

MIT has determined geothermal energy potential is higher by orders of magnitude than world use.
2012 research finds there is enough wind energy potential to power the world several times over.
Within 45 seconds, the Earth receives enough solar energy to fully meet the world’s entire energy needs for that day.
