What are the major causes of sea level rise?
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of seawater as it warms. The first graph tracks the change in sea level since 1993 as observed by satellites.
What are the main problems that climate change brings to Kiribati?
Rising sea level in Kiribati is expected to put populations at increased risk of storm surges and coastal flooding (page 3). In Kiribati, climate change could increase the risk of vector- and water-borne diseases and threaten food safety and security (pages 4, 5).
What is the main cause of sea level rise quizlet?
The two major causes of global sea-level rise are thermal expansion caused by the warming of the oceans (since water expands as it warms) and the loss of land-based ice (such as glaciers) due to increased melting. Sea ice is shrinking and thinning at an accelerating rate.
What are the effects of sea level rise?
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.
How will sea level rise affect Kiribati?
Sea-level rise linked to climate change threatens to render Kiribati uninhabitable well before it is completely submerged. Severe and frequent coral bleaching caused by warming ocean waters could hinder growth of Kiribati’s reefs, compounding the dangers of sea-level rise.
What are the impacts of sea level rise in Kiribati?
As water levels rise, towns in Kiribati are flooding and the island itself may be also soon be consumed by water. The streets of Kiribati are filling with water more and more often from the rising tides and an increase in storms. Citizens are frequently being displaced as their homes and businesses are being destroyed.
Where is the sea level rising?
Sea Level Rise Due to Melting Ice Sheets and Glaciers About 90% of this ice is in Antarctica. Most of the rest is in Greenland and a tiny fraction is locked up in mountain glaciers elsewhere.
How can we stop rising sea levels?
Reduce your footprint.
- Greenhouse gasses are a major contributor to sea level rise.
- buffers for coastal areas during rainstorms and hurricanes.
- from permeating into the ground and lead to an increase in runoff and erosion.
- clean the air and soak up rain.
- Obey “no-wake” zones.

What is the main reason for sea level rise quizlet?
The two major causes of global sea-level rise are thermal expansion caused by the warming of the oceans (since water expands as it warms) and the loss of land-based ice (such as glaciers) due to increased melting.
Which of these causes the sea level change over flooding due to process of melting of snow?
Another major factor for sea-level rise is melting of land-based ice. This consists of two factors, namely melting of mountain glaciers and ice caps, and melting and outflow of the ice sheets in Greenland and Antarctica. Ice sheets increase their mass by snow accumulation, and lose it due to melting.
What are the causes of climate change?
The main causes of climate change are:
- Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry.
- Deforestation – because living trees absorb and store carbon dioxide.
How high above sea level is Kiribati?
Home to more than 110,000 people, Kiribati is made up of 33 low-lying atolls spread across 3.5 million square kilometres of ocean. At their highest elevation, the islands average 1.8 metres (6 feet) above sea level. The island’s total land mass makes up 800 square kilometres (497 miles).
