What is global warming and why does it matter to the US?

Answer 1

Global warming is the warming of the earth since humans discovered fossil fuels (coal, oil and natural gas), and especially the rapid warming since 1980.

It matters to the US (and to the world) because if the earth continues to warm

• People will die from famines, flooding and heat waves.
• Countries (Pacific Islands) will disappear or have their coastal plains submerged by rising sea levels.
• Millions of people will have to move, and most of these will be extremely poor, with no support from their economically troubled governments.
• Animal, birds and fish species will disappear as their habitats go.

Answer 2

Global warming is the gradual increase in Earth's temperature due to human activities releasing greenhouse gases into the atmosphere, leading to climate change. It matters to the US as it can cause more extreme weather events, sea level rise, and disruptions to agriculture, impacting economy, infrastructure, health, and ecosystems. Addressing global warming requires international cooperation and national policies to reduce emissions and adapt to the changing climate.
