Sea level rise is an increase in the level of the world's oceans due to the effects of global warming.Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere.The oceans then absorb the majority of this heat. As water becomes warmer, it expands. This results in ocean levels rising worldwide.The Arctic has warmed nearly four times faster than the planet as a whole since 1979, a new study finds. The Arctic is heating up nearly four times faster than the Earth as a whole, according to
since 1970. Since 1900, the global average surface temperature has increased by about 1 °C (1.8 °F). This has been accompanied by warming of the ocean, a rise in sea level, a strong decline in Arctic sea ice, widespread increases in the frequency and intensity of heatwaves, and many other associated climate effects. Much of this warming has
Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately.
Scientists already have documented these impacts of climate change: Ice is melting worldwide, especially at the Earth's poles. This includes mountain glaciers, ice sheets covering West Antarctica
