What are the two greatest contributors to sea level rise?
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets.
What are the effects of rising sea levels?
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.
Where have some of the strongest and earliest impacts of global warming occurred?
Where have some of the strongest and earliest impacts of global warming occurred? Some of the fastest-warming regions on the planet include Alaska, Greenland and Siberia.
What is the impact of rising sea levels on climate change?
Changes in salinity alter seawater density, which can change major ocean currents that transport heat through the ocean driven by the currents, stimulating more climate change. Complete melting of glaciers and ice sheets would raise sea levels worldwide almost 70 meters (230 feet) above current levels.
How do rising sea levels affect climate change?
A warming climate can cause seawater to expand and ice over land to melt, both of which can cause a rise in sea level. The second mechanism is the melting of ice over land, which then adds water to the ocean.
What is Singapore doing for climate change?
Singapore has set a goal of reducing its greenhouse gas emissions intensity by 36\% compared to 2005 levels by 2030. Singapore is also working towards stabilising its emissions with the aim of peaking around 2030. These are ambitious targets, given Singapore’s limited options for renewable energy.

What is the global sea level rise?
In 2020, global sea level set a new record high—91.3 mm (3.6 inches) above 1993 levels. The rate of sea level rise is accelerating: it has more than doubled from 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century to 0.14 inches (3.6 millimeters) per year from 2006–2015.
