There is an urgent need to adapt cities and countryside to the damages caused by climate change.
Disasters such as the massive floods in Valencia, Spain, are the result of man-made climate change.
Greenhouse gas emissions will lead to more intense and frequent extreme climatic phenomena.
Many victims of such disasters could have survived if a proper warning signal had been given.
An alert issued 24 hours in advance can reduce damage by 30%.
There should be a global review of alert systems and land occupation plans.
Conclusion: If urgent measures are not taken in urbanization management and in reducing greenhouse gas emissions, extreme phenomena will continue to increase, causing more damage.
