Earlier this week the UN International Panel on Climate Change (IPPC) published its report on the oceans and climate change. We are once more warned of the consequences of climate change and the impacts of rising sea levels as well as on the urgent need to have decarbonisation in place by not later than the year 2050.

EU Commissioners Miguel Arias Cañete for Climate Action and Energy, Karmenu Vella for Environment, Maritime Affairs and Fisheries and Carlos Moedas for Research, Science and Innovation have welcomed the report, considering it a wake-up call for the global community to tackle climate change and its impacts on oceans as soon as possible. In an EU Commission press statement issued on Wednesday, they emphasised that the conclusions of the new report are clear: “human-induced global warming is drastically changing our oceans. They are heating up, becoming more acidic, contain less oxygen. Sea levels are rising much faster than anticipated.”

Chapter 4 of the report should be of particular interest to Malta. It is entitled “Sea Level Rise and Implications for Low Lying Islands, Coasts and Communities”.

Global Mean Sea Level is rising at an accelerating rate. From observations made it results that this has increased from 1.4 millimetre per year over the period 1901-90 to 3.6 millimetre per year over the period 2005-15. The report refers to various studies as to the projected sea-level rise. Beyond 2050 is unchartered territory due to the uncertainties in emission scenarios and the associated climate changes and the response of the Antarctic ice sheet in a warmer world. The relevant projections however still point towards a possible sea-level rise of 1.10 metres towards the end of the century. It is not excluded that this projection may be increased upwards to as much as 2 metres once additional studies are concluded.

These projections are based on scientific observations and the accumulated knowledge from studies on the impacts of climate change on the oceans, notably the increase in global temperatures as well as the resulting melting of glaciers and ice sheets.

Despite this uncertainty associated with such a wide range of the projections made, decisions on coastal adaptation planning are required to be made today. This would include decisions on critical infrastructure and coastal protection works which need to be put in place in anticipation of the most likely scenarios.

Rising sea levels are a threat to coastal residential areas as well as to most of our tourism and maritime infrastructure.

Our coastal areas are over-developed and densely populated. Tourism facilities and infrastructure is concentrated along the low-lying areas of the coast. For an island state the maritime infrastructure is crucial. As a consequence, sea-level rise may, even in the medium term, have a devastating impact on the Maltese islands unless we are adequately prepared not just for the likely scenarios but also for the worst case scenario.

Where do we go from here? Are we prepared for this developing emergency which is unfolding before us?

The answer is an obvious no. We are not prepared. There are no signs that any sort of preparation is in hand. The basic problem which we have to face is that even in the medium term our coast may be wiped out together with all  its infrastructure. We lack a clear vision of how to deal with climate change.

The Tourism Ministry is only interested in playing around with artificial sandy beaches which will be quickly vacuumed and reclaimed by the sea during the first storm as was clearly demonstrated in Balluta Bay during the last stormy season.  The Planning Authority is bent on facilitating making hay while the sun shines and has at no point factored climate change in its policies and decisions.

A healthy and vibrant coastline is essential. We can only protect it by being prepared for the developing climate emergency. If we do not we will have no one to blame but ourselves.
