The storms that
battered Portugal ’s entire coastline
recently, plus extensive flooding in England ,
prolonged drought in California , extreme cold
in northeastern America and extreme
heat in Australia ,
have created further confusion over climate change.
In the aftermath
of the most violent waves in 20 years, the cash-strapped Portuguese government
is committed to finding €300 million for reconstruction projects, and to
reassessing the national strategy for coastal protection.
This is being
done amid the backdrop of the National Strategy for Adaptation to Climate
Change (ENAAC), part of an initiative set in motion by the European Commission
to help EU members access and share information on the subject.
The EC’s view is
that the climate is certainly changing and that it will continue to do so with
far-reaching consequences. ‘Adaptation’ means anticipating the adverse effects
and taking appropriate action to prevent or minimise the damage they can cause.
“Early action
will save damage costs later on, so adaptation strategies are needed at all
levels of administration, from local to international,”
according to the EC.
So Portugal and the
EC seem to be in accord, but there is still considerable public confusion internationally
about the way in which the climate is changing and whether or not humans are
making things worse.
Opinions differ
among the global ‘experts’ and it is hard to know who to believe because the
science is all so iffy.
Prime Minister
David Cameron told the British
parliament that climate change could be behind the relentless rains and
flooding that wreaked havoc on Britain
recently, but according to the British Met office “it is too early” to make
that kind of judgement.
With the same
sort of diffidence, the Intergovernmental Panel on Climate Change (IPCC) - the
world leader on research into climate change – last year published a report claiming
there was some evidence linking some types of extreme weather with
man-made climate change.
Extreme weather
events have been occurring sporadically throughout history (at least since
Noah’s time, according to Genesis). But the chances of them occurring nowadays seem
to be increasing. Global warming is increasingly getting the blame.
But is the globe really
warming? Many people sitting around their firesides in the northern hemisphere this
winter find it hard to believe. Some think it feels more like another ice age
on the way.
Part of the
bewilderment lies in a misunderstanding of the words ‘weather’ and ‘climate.’ The
difference is that ‘weather’ is defined as atmospheric conditions over a short
period of time, whereas ‘climate’ refers to conditions over relatively long
stretches – months, years, decades or more.
Presenters on Fox
News, famous for denying the existence of global warming, predictably used the recent
deep freeze in the US
to mock the scientific evidence on climate change.
Donald Trump went
further and used the stranding of a Russian research ship in ice in Antarctia
as another reason to demand in a tweet: “this very expensive global warming
bullshit has got to stop.”
The great
majority of climatologists believe that weather patterns and trends (rather
than individual events) suggest the planet is indeed getting warmer, that carbon
dioxide emissions are compounding the situation and that to deny this could
have dire repercussions.
Within Europe, Portugal and
the Mediterranean countries are thought to be the most vulnerable to climate
change. With or without stringent controls on CO2 emissions, the long-range
forecast is for less rainfall, more heat-waves and droughts. Sea levels are
expected to rise significantly, placing much of the coastline at risk before
the end of the century.
All this could
severely affect such things as food production and the tourist industry. Desertification could make the landscapes in southern
Portugal more like those in
northern Africa .
More clarity about
what is going on could be just around the corner. Researchers and policy-makers
will be attending a three-day international conference in Lisbon 10-12 March. The objective, say the
organisers, Circle-2: “To share the results of 10 years of co-operation in
climate change impacts, vulnerability and adaptation research and pave the way
for the development of new research in support of climate change adaptation in Europe in the next decade.”
