Global warming refers to the ongoing increase in the average temperature of Earth's atmosphere and oceans. It is widely recognized as a primary manifestation of contemporary climate change.
Earth's climate has constantly fluctuated throughout history. Our planet has experienced multiple ice ages, where vast ice sheets and glaciers expanded across the continents, as well as warmer interglacial periods when temperatures exceeded those of the pre-industrial era.
Historically, these shifts in Earth's climate occurred gradually, over hundreds of thousands of years. The current warming trend, however, is progressing at an unprecedented pace. Natural cycles of heating and cooling cannot account for the rapid temperature rise observed in such a short time. This accelerated change is attributable to human activities, particularly the burning of fossil fuels, deforestation, and even practices like the widespread use of inefficient cook stoves, which release significant greenhouse gases and other pollutants. Scientists are concerned that the climate is now changing at a rate faster than many species can adapt, posing a severe threat to global ecosystems.
