Catastrophic Climate Change: It's Here - Deal With It.


2019.01.01

Whatís the next thing thatís going to kill us?
- Chris Hadfield (Canadian astronaut)

Here's the deal.
●Catastrophic climate change is real and happening now. It's killing people and creating climate refugees. Watch the news and connect the dots.
Human activity is the fundamental cause; especially the massive and growing use of fossil fuels per person, multiplied by increasing population.
●Whereas temperature rise is correctly perceived as the dominant impact of CC issue there are multiple other inter-related others on which human survival depend: availability of potable water, declining health of the oceans and arable land.
●While climate change is inextricably linked to how we use material resources its effects will incur unprecedented stresses on maintaining peace between peoples who will be increasingly deprived of the means of survival.
●You have been fed a lot of disinformation by the fossil fuel industry, who have known about this since the 1960s.
Fixing climate change is cheaper than dealing with the consequences.
●The rate of change is accelerating, there are catastrophic threshold (tipping) points, and there are 'positive feedback loops' (not positive in the sense of being beneficial to us and our descendants) which we have not yet really taken into account.
●Wide-scale geo-engineering without an off-switch is a really bad idea based on the human track record, often attended by unintended consequences, when we're dealing complex systems we don't understand well. (Consider the current state of 2-week weather forecasts; now contemplate 100-year predictions based on our current state of knowledge and understanding.)
●Climate modelling of far greater sophistication than used today is required to get a better sense of how various factors will interact and of likely consequences to help evaluate adaptation plans, or estimate outcomes from various mitigation strategies.
●The UN IPCC is hopelessly optimistic and are building models based on years-old data, not recent knowledge, and they do not take into account tipping points and feedback loops.
There are things we can do, today, which just might allow the survival of the human race.

We have no idea how dependent we are upon having a stable environment to sustain our population on this planet. We have no experience as a species with a climate which moves outside 'normal' patterns; the patterns and thresholds where we have evolved over the millennia. The short mandates of our political systems do not accommodate the medium and long term thinking we need to do to deal with climate change. This leads to consistently poor policy-making in the short term; it may well constitute crimes against humanity when we come to grasp the enormity of the consequences.

Those who argue the economy must trump the environment miss the most important, fundamental point in the discussion: without 'the environment', there is no economy, no civilization, no humans. No humans. That is not intended to be a hyperbolic statement, but to start a discussion about the probability of this event as a consequence of catastrophic climate change already in motion, and what, if anything, we will choose to do about it. Science fact: carbon dioxide levels have been this high on planet Earth before (over 400 ppm), but not while mammals - let alone humans - lived here.

We caused this mess. It's up to us to fix it. So, let's get to it.
