Climate change poses risks to everyone and demands our collective attention. Actions to mitigate global warming, adapt to a climate that has already changed, and prepare for imminent climate events require everyone's engagement. Communities, cities, and countries face an unprecedented demand for coordination and communication. Social network sites, instant messaging apps, Short Message Service (SMS) and e-mails are information and communication technologies (ICTs) widely used for climate communication and coordination. However, these technologies' effectiveness and method of use are frequently questioned. Which kind of adaptation and preparedness actions can benefit these technologies? What harm can happen to people when they are not used properly? This essay aims to discuss answers to these questions.
