Anthropogenic climate change is supported by a wide range of robust, interlinked evidences drawn from atmospheric science, cryospheric studies, oceanography, and ecological observations. One of the most direct evidences is the rapid increase in greenhouse gas concentrations, particularly carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), since the Industrial Revolution. Ice core records from Antarctica and Greenland reveal that pre-industrial CO₂ levels were about 280 ppm, whereas current concentrations have exceeded 420 ppm. This sharp rise corresponds closely with fossil fuel combustion, deforestation, and industrial activities, clearly indicating human influence rather than natural variability. Another critical line of evidence comes from global temperature records. Instrumental data since the late 19th century show a consistent warming trend, with the last few decades being the warmest on record. Climate models that incorporate only natural factors such as volcanic eruptions and solar radiation fail to explain this warming, whereas models that include anthropogenic emissions successfully reproduce the observed temperature rise.
