Aim for limiting global warming 1.5centigrade as main output no just net zero carbon dioxide

Reduced carbon emissions by nations, companies and individuals has been the main target for international and climate change negotiations.

The emphasis on reducing carbon emissions often obscures the real reason why we need to take action which is human induced global heating and the resultig environmental effects.

The Paris agreement of limiting global heating to 1.5C needs to be the overarching target.

We can then use science to work out when Scotland needs to be at absoloute zero carbon emissions and use the Citizens Assembly to negotiate how this reduction can be phased in as part of a Just Transition.   

Currently the 1.5C target of global heating is looking very precarious and net or absolute zero results by 2045 or 2060 are not following the science  Net or absolute zero targets by those years do no account for trigger points like permafrost methane release and ice cap collapses which are happening now.

Why the contribution is important

As the above statement there are a range of climate emergency events across all countries that are accelerating in scale and devestation to natural and human managed environments. 

The focus on net or absolute zero carbon targets gives a false sense of security and control which we don't have.

The net or absolute zero carbon targets totally ignore the growing carbon emissions from melting permafrost and forest fires which have the potential to exceed human produced carbon emissions.

A focus on limiting global heating to 1.5C could take into account the growing importance of global heating destruction of natural carbon sinks and reset the human produced emissions allowance accordingly.

    I like the emphasis on this idea, i.e. aim for 1.5 degrees, rather than say limiting to 1.5 to 2 degrees. The only thing is that temperature is the end goal. I would still keep carbon emissions as the proxy for monitioring and evaluating where we are heading, but instead of date, I would suggest Scotland allocates itself a carbon budget that is fair and Just.

    We should aim to be negative carbon, not just zero carbon. We need to stop emitting carbon as fast as we can, and faster. And also aim to draw down and store carbon. It is possible. See the work of Walter Jehne.
