One of the most promising climate services for the health sector are heat and cold early-warning and alert systems . These have been developed by the national meteorological institutes in Peru, Argentina, and Uruguay . A heat alert system was implemented in Argentina in 2017 and daily alerts are issued for 57 localities across the country. A stoplight colour scheme is used to issue alerts, identifying specific groups at risk and actions to be taken to reduce the risk .
