Climate change accelerates

Europe’s regions are facing rising sea levels and more extreme weather, such as more frequent and more intense heatwaves, flooding, droughts and storms due to climate change, according to a European Environment Agency (EEA) report published today.

The report assesses the latest trends and projections on climate change and its impacts across Europe and finds that better and more flexible adaptation strategies, policies and measures will be crucial to lessen these impacts.

Temperatures in mountain ranges such as the Alps and the Pyrenees are predicted to soar to glacier-melting levels, while the Mediterranean faces a ‘drastic’ increase in heat extremes, droughts, crop failure and forest fires.

Hans-Martin Füssel, a lead author of the EEA report, said that scientific evidence was pointing increasingly to a speeding up in the pace of climate change.

“We have more data confirming that sea-level rise is accelerating,” he said. “It is not a linear trend, largely due to increased disintegration of ice sheets. There is also new evidence that heavy precipitation has increased in Europe. That is what is causing the floods. Climate projections are coming true.”

Earlier this month, NASA, NOAA and the UK Met Office confirmed that 2016 had broken the record for the hottest year ever - previously held by 2015, which had itself broken the record that had been set in 2014.

Hans Bruyninckx, the director of the EEA, says there was now “not a snowball’s chance in hell” of limiting global warming to 2C without the full involvement of the US, which has just elected a climate-sceptic president.

Europe’s thermal growing season is now 10 days longer than in 1992, with delays to the end of the season more dramatic than the advance of its start. In countries such as Spain, warmer conditions are expected to shift crop cultivation to the winter.

New records continue to be set on global and European temperatures, sea levels and reduced sea ice in the Arctic. Precipitation patterns are changing, generally making wet regions in Europe wetter and dry regions drier. Glacier volume and snow cover are decreasing.

At the same time, climate-related extremes such as heat waves, heavy precipitation and droughts, are increasing in frequency and intensity in many regions. Improved climate projections provide further evidence that climate-related extremes will increase in many European regions.

“The scale of future climate change and its impacts will depend on the effectiveness of implementing our global agreements to cut greenhouse gas emissions, but also ensuring that we have the right adaptation strategies and policies in place to reduce the risks from current and projected climate extremes,” adds Bruyninckx.

All European regions are vulnerable to climate change, but some regions will experience more negative impacts than others. Southern and south-eastern Europe is projected to be a climate change hotspot, as it is expected to face the highest number of adverse impacts.

This region is already experiencing large increases in heat extremes and decreases in precipitation and river flows, which have heightened the risk of more severe droughts, lower crop yields, biodiversity loss and forest fires. More frequent heat waves and changes in the distribution of climate-sensitive infectious diseases are expected to increase risks to human health and well-being.

Coastal areas and flood plains in western parts of Europe are also seen as hotspots as they face an increased risk of flooding from rising sea levels and a possible increase in storm surges. Climate change is also leading to major changes in marine ecosystems as a result of ocean acidification, warming and the expansion of oxygen-depleted dead zones.

The report is intended to spur Europe’s sluggish moves towards adaptation strategies for dealing with the impacts of climate change, ahead of an EU review later this year.
