Climate Change

What are the effects of global warming?

• Rising sea levels, melting ice caps and glaciers, more frequent and severe weather events, changes in ecosystems and biodiversity, and negative impacts on human health and economies.

• Improved agricultural productivity and increased crop yields due to longer growing seasons.

• Decreased temperatures and colder climates, leading to an ice age.

• Decreased rainfall and droughts, increased desertification, and water scarcity.

What is the primary greenhouse gas responsible for global warming?

• carbon dioxide (CO2)

• methane (CH4)
