How is climate change defined?

The definition of climate change typically refers to significant and lasting changes in the global or regional climate patterns, often associated with shifts in temperature, precipitation, and other atmospheric conditions. The correct answer emphasizes that contemporary climate change is primarily attributed to human activities, notably the increase in greenhouse gas emissions from sources like fossil fuel combustion, deforestation, and industrial processes. This human-induced climate change has led to a rise in average global temperatures and has been scientifically linked to the accelerated rates of climate shifts observed over recent decades.

This understanding is rooted in extensive research and data that demonstrate the correlation between human activities and observable climatic changes, marking a distinction from historical natural cycles or variations tied to seasonal changes or non-anthropogenic factors. Addressing climate change effectively requires acknowledging humanity's role in it, thereby underscoring the urgency for actions aimed at reducing emissions and mitigating its impacts.
