Greenhouse effect
A natural function of the Earth's atmosphere is to keep in some of the heat that is lost from the Earth to support life. It works like a glass greenhouse by:
This atmosphere allows the heat from the Sun (short-wave radiation) to pass through to heat the Earth's surface.
The Earth's surface then gives off heat (long-wave radiation), the greenhouse gases trap this to stop it radiating back into space.
Trapping heat via greenhouse gases (e.g. water vapour, methane, carbon dioxide and nitrous oxide), which would otherwise escape back into space.

Adaptation strategies
They do not aim to reduce or stop global warming. Instead they aim to respond to climate change by limiting its negative effects. Strategies include:
-
Reducing risk from sea level rise - sea levels risen 20cm since 1900, average sea level rises of 1m are possible by 2100.
-
Increased rates of coastal erosion and damage from storm surges. Solution - restoration of coastal mangrove forests, tangled roots trap sediment and offer protection from storm waves.
Land in low lying areas such as Bangladesh, Vietnam & India are threatened.
Use sea defences such as, construction of sea walls, to protect the land from being eroded away. E.g. a 3m sea wall is being constructed around the capital Male (Maldives).
-
Construction of artificial islands (the Maldives ) up to 3m high so that people at risk could be relocated. Or just relocate to Sri Lanka until that floods.
