What are the impacts of climate change in Tuvalu?
According to local climate data, Iona says the biggest impacts of climate change on Tuvalu have been rising air temperatures, more intense and frequent storm surges and decreasing rainfall, as well as the total inundation of low-lying coastal parts of Funafuti – including, sometimes, the country’s lifeline, its runway.
What are the social impacts of climate change in Tuvalu?
Social Impacts: ➢ People have had to move from their homes as a result of the rising sea levels. ➢ Mass migration may have to occur if a solution is not found. This will be the first of its kind as a result of climate change. ➢ If this occurs, families will be split up.

What are the causes to the rising sea levels in the Pacific?
Rising sea levels, one of the effects of global warming, is brought on by two main factors, the melting ice sheets and glaciers, and the expansion of seawater as it warms.

What are the impacts of sea levels rising?
The major physical impacts of a rise in sea level include erosion of beaches, inundation of deltas as well as flooding and loss of many marshes and wetlands. Increased salinity will likely become a problem in coastal aquifers and estuarine systems as a result of saltwater intrusion.
What are some of the consequences of rising sea levels?
Sea level rise poses a serious threat to coastal life around the world. Consequences include increased intensity of storm surges, flooding, and damage to coastal areas. In many cases, this is where large population centers are located, in addition to fragile wildlife habitats.
