Our blind adherence to what exists stands between us and
mitigating the effects of climate change.
It is not too difficult to see and understand how our global temperatures continue to rise. |
Emerging dilemmas have the potential to decimate humanity
with climatologists illustrating, unquestionably, that the human-induced
changes to earth’s atmosphere, and so the earth’s weather patterns, are so
expansive and dramatic, that the near “goldilocks” conditions of the past
10,000 years of “not too hot, not too cold, but just right” are quickly ending.
Earth’s surface temperatures are nearly one degree above
pre-industrial levels and carbon dioxide levels in the atmosphere have risen
from about 280 parts per million (ppm) prior to the 18th century to
nearly 400 ppm today, breaking the nexus we have enjoyed for millennia between
rather pleasant, predictable and understandable weather and something that is
quite different and largely untenable for many species on earth, among them
humans.
Circumstances arising from lifestyles rooted in a paradigm
that depend upon endless growth and the continued combustion of fossil fuels,
primarily coal and oil, threaten us all and will only get worse before they get
better for carbon dioxide, a natural by-product of that process is a long-lived
chemical compound and so what is produced today will be with us for centuries
to come. The maxim, “This too shall pass” doesn’t apply.
At a less than one degree increase in global temperatures we
are witnessing some unexpected changes to the world’s weather, changes to which
humans and associated infrastructure are not adapted, and yet a two degree
increase is not simply predicted, rather unavoidable; changes that will bring
with them what we, humans and many other species, will find not only
challenging, but rather difficult to survive.
The science of climate change is quite complex, but even a
layperson can understand it to see that what lies ahead will be, by brute
insistence, quite different from what has been.
Proposals to avert the difficulty (we can no longer avoid it
for we are 30 years too late) include high-risk and unproven geo-engineering
ideas, including carbon dioxide sequestration, and significant alternative
energy intervention (unlikely as the fossil fuel industry has massive political
and social clout), but never have we truly explored dramatic changes to our way
of living, substantially reducing energy use, changing our egoistic consumptive
wants and switching our near obsessive interest from building bank balances to
building resourceful and resilient neighbourhoods.
