UN says transport infrastructure must adapt to climate

Transport infrastructure across Europe, North America and central Asia must adapt to more adverse climate conditions, the United Nations said on Tuesday, warning that inaction could prove more costly than upgrades.Roads, railways, waterways, ports and airports will face a greater likelihood of flooding, high temperatures, reduced snow, ice and permafrost, and sea level rise from 2050 to 2080, the UNECE regional agency said.UNECE covers 56 countries across Europe, North America, the Caucasus and central Asia.
