A long definition of global warming?

Answer 1

Global warming is the continuing rise in the average temperature of Earth's atmosphere and oceans. The evidence for this temperature rise is unequivocal and, with greater than 90% certainty, scientists have determined that most of it is caused by human activities that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning of fossil fuels. This finding is recognized by the national science academies of all the major industrialized countries.

Answer 2

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities like burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. These gases trap heat from the sun, leading to a gradual warming of the planet and negative impacts on weather patterns, ecosystems, and human health. Addressing global warming requires reducing greenhouse gas emissions and transitioning to cleaner, more sustainable energy sources.
