        abstract = {This paper presents the design and implementation of an IoT-based climate change monitoring system on the ESP32 microcontroller platform. The system integrates five MQ-series electrochemical gas sensors (MQ-2, MQ-6, MQ-7, MQ-9, MQ-135) for comprehensive real-time monitoring of ambient air quality parameters associated with climate change and atmospheric pollution. Sensor data is acquired via a 12-bit ADC with 10-sample averaging, transmitted as JSON payloads at 115,200 baud every 5 seconds, and pushed to the ThingSpeak IoT cloud every 10 seconds over WiFi. A rotating 16x2 I2C LCD display provides local readout. A WiFi watchdog ensures autonomous reconnection. Results from eight-hour deployments confirm stable sensing, accurate cloud telemetry, and reliable fault recovery, demonstrating a scalable, affordable platform for distributed environmental monitoring.},
