The global warming debate can at its most feverish state
reach dizzy depths. Hot air and defensive name calling of sceptics as deniers
is destructive of sensible discussion. The climate has always fluctuated,
changed and indulged in cyclic fashion. The climate has always had its periods
of warming and has done so for millions of years.
Where I live in Marlborough if you chance to travel along
state highway 63 to the West Coast, the road will follow the valley towards St
Arnaud and Lake Rotoiti. Towards an hour’s drive, the highway comes to
its first significant rise. That low hill is the old moraine from a glacier
that several million years ago, a glacier groaned, ground and grated
down the Wairau valley pushing rubble ahead of it to about the Wairau
River’s confluence with its tributaries the Branch and Goulter Rivers. The
moraine from the glaciers is evident in the low mound-like hills on both the
Wairau River’s east and west banks.
Head south to Central Otago and the St. Bathans
area.
Sixteen or so million years ago in the Miocene period, Otago
warmed to almost tropical temperatures. Fossil leaf deposits revealed the
then presence of eucalypt forests. George Gibbs in his brilliant book “Ghosts
of Gondwana” (2017) wrote fossils from Central Otago that included a turtle and
a small crocodile, “testify to a much warmer sub-tropical climate”. So the
climate had warmed to produce this startling sub tropical environment and
then cooled to become the climate it is today with hot summers and cold
winters.
Undeniably the climate fluctuates cooling and then warming
in cyclic fashion.
These natural climate fluctuations seem to have been lumped
into the total global warming by the global warming theorists.
The equation is natural climate change plus or minus
man-induced climate change equals the real state of the climate trend.But to
ignore natural climate change is distortion of the real situation.
Take a trip from the South to the North Island and
more specifically, the Ruahine Ranges. Hawkes Bay botanist and hydrologist
the late Dr Patrick Grant was intrigued by 19th century explorer missionary
William Colenso diary descriptions of the mountain ranges which he crossed to
preach in the Taihape district. Colenso wrote of dead and
decaying trees, shingle choked stream beds and giant mountain slips. In the
1950s, Government departments and Forest and Bird blamed the erosion and
forest “damage” to wild animals such as deer and possums. But Dr
Grant’s research debunked that theory. Instead he identified cyclic
periods of dramatic natural climate change going back to 1530 with extreme weather
of gales and storms causing forest damage. Droughts happened too.
During 1909-15 there were several dry years that
exponentially amounted to worsening drought and culminating in “the mother of
all droughts" in 1915-16. The series of droughts killed 100-plus year old
trees leaving dead spars for which wild animals were erroneously blamed. Dr
Grant’s work showed climate change and extreme weather occur naturally.
In recent years, international conferences have been held to
tackle climate change but they miss that basic point that climate change is and
has always been happening. From the “babble-fests" of conferences arose
the Kyoto Protocol to deal with climate change, natural and/or man
induced.
The late Owen McShane NBR columnist, planning consultant,
said in 2003 that the the protocol developed out of the IPCC conference in
Kyoto “is a fraud, because it is based on fraudulent assumptions, fraudulent
models and fraudulent manipulations of data — Claims that the climate is static
and unchanging are fraudulent.”
He concluded “this necessarily means that the Kyoto protocol
itself is a fraud and that our (NZ) government is the victim of a major scam.”
Arising from the Kyoto Protocol was carbon trading
designed “to allow nations who are unable to meet their carbon emission
reduction targets, to purchase carbon credits under a unified regulatory
framework.” In short it means “wheeling and dealing” carbon credits. It is a
free market capitalist approach to a perceived serious environmental problem.
As such it won’t work. Corporates’ primary interest are profits bereft
of environmental conscience. In itself carbon credits are very
arguably a scam, costly to the people and only benefiting corporate gamblers
aiming to reap rich profits financially.
Monocultures of pine forests are not the answer as they are
environmentally detrimental in many ways such soil acidification, depleted
streams and heavy siltation at logging time.
Whether one is a global warming disciple or denier is really
immaterial. The world does have an environmental crisis. New Zealand with less
than 5 million people has a looming environmental crisis. And we’d all better
do something to combat it.
Whether it’s global warming or the big environmental
picture, the major cause is people and the lack of a population policy.
People.
The
cause of the problem is people and politics. Political hot air cannot hide the
reality of degraded rivers, fisheries mismanagement, air and water pollution,
exploitive monocultures, raw sewage in rivers and coastlines at high rainfall
times, ailing soil health and other symptoms.
It’s clear whether you believe in climate change or not, the
world faces the bigger picture of declining environmental health due to human
activities. The sharp reality is more people and more consumers equal more
resource exploitation, on-going demand for more costly infrastructure such as
motorways, cause more emissions and jettison more garbage. More, more and more
- an addictive disease.
The planet cannot tolerate infinite growth. It’s already at
a crisis. The big problem is not global warming. The big problem is the
environment in total.
