European territories confronted with climate change: Awaiting the events or timely preparation?

Today, climate change is viewed as one of the main global challenges. The EU has become a major player in the political arena and seeks to reach worldwide agreements on 'mitigation' policies to reduce greenhouse gas emissions. Despite speaking with one voice at the global scale, the effects of climate change on European territories vary widely according to local circumstances. The ESPON scenarios explore what those impacts could be, and what effect EU climate change adaptation policies would have. The first scenario envisions an EU policy limited to emergency funds following extreme events like floods and droughts. In the second scenario, the EU takes a much more proactive stance by funding radical and costly adaptation strategies. The exercise demonstrates the difficulty in identifying the cost-effectiveness of each approach. Territorial effects are often indirect and affect a variety of economic, social and ecological systems. Moreover, a great deal of uncertainty exists surrounding their magnitude and timing.
