Our actions today are a first draft in designing the future. They are tomorrow’s blueprint. Our future as well as that of future generations.
The ice sheets are melting at a faster rate than ever before. The resulting sea-level rise will obliterate coastal settlements around the globe. Even the Maltese islands will be impacted by a sea-level rise, irrespective of its magnitude. The larger the sea-level rise the more severe the impacts.
On a global level the sea is rising around 3 millimetres per annum. This varies with region. This variation may be insignificant to the naked eye and as result many would not even notice it.
No one can state with certainty as to how much the sea level will eventually rise. It is however clear to the scientific community that an increase in the mean global temperature is a major contributor. Islands and coastal communities all around the world will bear the brunt of this sea-level rise.
In the Pacific Ocean the sea has risen at a rate of three times the global average. A number of low-lying islands have already disappeared below the sea. In the Indian Ocean, The Maldives, a major touristic destination, risks losing 77 per cent of its land with a 50-centimetre sea-level rise. It will completely disappear if the sea level rises to a metre or more.
There is a time lag between our actions and sea-level rise such that we can substantially decrease sea-level rise in the future if we act appropriately now.
This is the reason underlying the EU’s policy of carbon neutrality, that is taking steps to ensure that net carbon emissions are reduced to zero by 2050, preferably earlier.
The Mediterranean Sea is a hotspot of climate change. Mediterranean experts on climate and environmental change within the framework of the UNEP Mediterranean Action Plan have drawn up a report entitled “Risks associated to climate and environmental changes in the Mediterranean Region”. This report points at the enormous challenges facing the Mediterranean due to the projected rising temperature in the region.
Without policy change it is estimated that the Mediterranean Region will, on average, be 2.2 degrees warmer in 2040 than it is today. This will have a considerable impact on water resources, agricultural production and health, amongst other issues. By 2100 without meaningful policy change this could lead to a one metre rise in sea level impacting severely the coastal communities in the Mediterranean.
The tourism industry, with most of its facilities situated along the coastline, will be obliterated. The impacts of climate change will be so severe that Covid-19 impacts will seem to be child’s play in comparison.
All over the world governments have been reluctant to act and take definite action on climate change to limit the potential temperature rise to 1.5 degrees Celsius and definitely to not more than 2 degrees Celsius. The commitments made at the Paris Climate Summit in 2015 are a welcome first step, but they are certainly not enough.
It has been estimated that if all commitments made in Paris are adhered to, we would still be on track to hit a temperature increase in excess of the two-degree limit. This would lead to a global disaster.
The first to bear the brunt will be islands all around the globe followed closely by low-lying coastal areas. This is the reason for island states being so vociferous in Climate Change fora, insisting for more action. It is unfortunate that Malta’s voice is not sufficiently heard in such fora. It is about time that we get our priorities right. Our relative silence is writing off future generations in the Mediterranean.
