It is actually not hard to understand the basic premise of climate change, you burn stuff made out of carbon and the amount of carbon in the air increases in direct proportion.
Carbon in the air combines with oxygen forming CO2, this acts like a blanket and traps more of the sun’s thermal radiation in the atmosphere, hence global warming. This warming effect energizes climate systems which in turn changes the weather, ie climate change.
The earth’s bio-systems are actually pretty resilient and able to tolerate a lot of stress whilst remaining relatively stable. This self-regulating effect, much as how our bodies regulate temperature, only works within a narrow tolerance range, when we step outside of the warm/ safe zone, things get really unstable quickly and outcomes become impossible to predict.
Scientists are certain about all of this, the only uncertainty is just how bad and how dangerous is the situation exactly and what will it be like this time next year? We will only know these answers with hindsight. The key point is: Science is certain about what is happening and when confronted with the amassed evidence governments are forced to agree with it, hence the Paris Accord.
The escape route it short and sharp,
We will have to crash-land the carbon economy over the next three decades and think up some other way of doing things pretty quickly. This is none negotiable, in terms of the science and in terms of our economy,
which also has to change rapidly to reflect our sudden shift in priorities.
We wont be able to sustain the same kind of GDP growth we became accustomed in the last century in this one. GDC will drive the future economy. Gross de-carbonisation. The future economy will reward innovators not in the through-put of energy and materials (GDP) but in fnding economically efficient ways of carbon sequestration and substitution.
Trump can trumpet for coal all he likes but he is rolling stones uphill and gravity will always win out in the end.
The final thing to know about Climate chang and the Paris Accord is that when confronted with all the evidence and with no way to escape the reality, 195 governments around the world agreed to sign it.. but they only agreed to committing to 50% of the measures required to avoid climate catastrophe, (in effect 4 degrees of change when the agreed target is 1.5 with an absolute ceiling of 2). Politics in its bigger sense has therefore failed us.
Democracy and economics
Governments therefore are not the leaders, they will have to follow.
It is down to community, individual action and our collective political and economic impact to shape and form the future. Together we must find a way to forge the road to a carbon neutral 2050.
