What measures have been implemented in Rio de Janeiro due to the record-breaking temperatures?

Rio de Janeiro has triggered a Heat 4 alert for the first time after reaching a record temperature of 44 degrees Celsius. This alert is activated when temperatures between 40-44°C are expected to persist for at least three days, prompting authorities to implement a safety plan for residents and tourists amid desert-like conditions affecting daily life. In response, residents and tourists are seeking relief at beaches and public showers. Mayor Eduardo Paes has issued precautionary recommendations for Carnival activities, as the city works to protect people from the extreme heat wave that has dramatically impacted normal activities throughout the city.
