Portugal
was among the 20 countries in the world most affected by global
warming over the past 20 years, according to a Global Climate Risk
Index report presented at the climate change conference in Paris.
“The
Index indicates the level of exposure and vulnerability to extreme
events that countries should understand as a warning to be prepared
for more frequent and more severe events in the future,” says the
report.
The
20-year index covering the period 1995 to 2014 is dominated by some
of the least developed countries in the world.
Portugal appears
in 19th place, third in Europe after Germany and alongside France.
The UK, which was struck this week by devastating floods, is well
down the list at 58.
The
Index says there have been more than 15,000 extreme climatic events
over the past 20 years resulting in 530,000 deaths, immense wastage in
food production and financial losses exceeded 2.8 trillion euros.
The
Rockefeller Foundation estimates that over the past 30 years, one
dollar in every three spent in development was lost as a result of
recurrent climate crises.
Behind
the most obvious extreme events, such as floods, landslides,
heatwaves and droughts, lurk melting glaciers, increases in ocean
acidity and ominous rises in sea levels.
Sea
levels along the shores of mainland Portugal have been rising
annually over the past decade by more than four millimetres, twice as
much as in the previous two decades, according to a report
commissioned by the government and published last year.
Increases
in average summer temperatures of 1ºC to 2ºC in the Azores,
2ºC to 3ºC in Madeira and up to 7ºC on mainland
Portugal have been predicted by climate specialists.
The
aim expressed during the Paris conference is to keep average global
increases to below 2ºC. Feared average increases of 4ºC
could elevate sea levels to a height that would swamp almost every
coastal town and resort in the Algarve, as well as the lower parts of
Lisbon and two-thirds of the world’s other major cities.
At
the start of the Paris conference, United Nations Secretary-General
Ban Ki-Moon launched an initiative aimed at “anticipating the
dangers, absorbing the impact and reshaping development” to avoid
the risks of climate change facing 634 million people living
in coastal areas and drought and flood zones.
It
is expected that detailed agreements on this and other measures will
be signed before the talks wrap up in Paris at the weekend.
Meanwhile,
the authors of the Global Climate Risk Index acknowledge that
individual extreme events (such as in Albufeira last month) cannot
necessarily be attributed to climate change caused by humans.
Moreover,
the authors recognise that their latest report is only one
piece in the complex jigsaw of climate change statistics. The events
recorded do not serve as a projection for future occurrences – but
they are certainly an indication that should be taken very seriously.
The
good news is that during a recent congress of the Portuguese
Association of Renewable Enterprises, the state energy secretary,
Jorge Seguro, emphasised the importance of investing in the renewable
industry. He said that with the help of green energy investments this
country had already reduced its fossil fuel dependence from 85% to
72%.
Between
2010 and 2013, Portugal saved €5.3 billion in imports of fossil
fuels (gas, solid fuels and oil) thanks to renewables. The industry
created 40,000 jobs and exported products worth €300 million.
The
goal is to increase the use of renewables in Portugal to 31% by 2020.
