How long have scientists known about the problem of global warming and what are the implications of this knowledge?

Answer 1

Scientists have known about the problem of global warming since the late 19th century when the greenhouse effect was first proposed. The implications of this knowledge include rising global temperatures, melting ice caps, sea level rise, extreme weather events, and threats to ecosystems and biodiversity. Addressing global warming is crucial to mitigate these impacts and protect the planet for future generations.
