Catastrophic Climate Change: It's Here - Deal With It.
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 (real) 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
other factors on which human survival depend: availability of potable water, declining health of the oceans and arable land, and more.
●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
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. Until we have a handle on that, our best path forward is to move toward an
atmosphere with less greenhouse gases to return planetary systems to a more stable state.
●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. In short, we don't have 12 years as indicated in their
last report. We have months to start making changes, and we have to get serious about meeting targets like the Paris Agreement,
but before 2030.
●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, and especially the past 10,000 years. 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 -
We caused this mess. It's up to us to fix it. Our future depends on it. So, let's get to it.
