The World Meteorological Organization (WMO) warned that global temperatures may temporarily surpass 1.5 C of warming within the next five years. This change is caused by heat-trapping greenhouse gases and the naturally occurring El Niño event. Stephen Hodder MBE, Chair of the CIC Climate Change Committee, said that this is a challenge to construction and engineering professionals to reduce carbon emissions associated with the built environment and address the linked biodiversity emergency. He also said that there is no excuse for professional institutions not to act.
