It states that global warming is largely caused by human greenhouse gas emissions and is causing glaciers to melt, sea levels to rise, and wildlife to change locations. Additionally, it explains that warmer temperatures lead to more humidity and changing weather patterns. The global climate is reported to be getting hotter based on observable signs like melting glaciers and animal migrations.
