**2. Signatures of climate change**

Climate change may manifest in weather extremes: floods, torrential rainfalls, radical storms, cold spells, heatwaves, severe droughts, and wildfires. These events could cost life; destroy residential and commercial buildings, public utilities, and infrastructures; lead to contamination of natural resources (e.g., air, soil, and water bodies); disrupt numerous functions including schools; social events; air, land, and sea transportation.
