Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

The main culprits are carbon dioxide and methane. The concentration of carbon dioxide has been increasing since the middle of the 18th century, and this is associated with two factors, changes in land use and the burning of fossil fuels.

Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening low-lying islands and coastal cities.
