adapting to climate change Flashcards
what is ‘adaptation to climate change’
changing behaviour or systems to reduce the impacts on people/wildlife /property
what are the three methods for adaptation
-reducing risk fro sea level change
-change in agricultural systems
-managing water supply
how much has the global average sea level risen since 1990
21 cm
according to 2019 IPCC report how much is the global sea levels expected to rise above sea levels in 2000
by 30cm to 1.1m
as sea levels rise what will also increase
coastal erosion
what are negatives of sea levels rising
-fresh water supplies will become contaminated by saltwater
-many coastal areas will be prone to damage from storm surges
what is the example for sea levels rising
the Maldives
what is the Maldives and where
a group of tiny islands in the Indian Ocean
what is the highest point in the Maldives
2.4 m
when is it said the Maldives islands will be submerged
2070
how many inhabitants are there in the Maldives
380,000
what is being done to adapt to sea levels rising in the Maldives
-sea walls built
-people relocated to Sri Lanka or india
-artificial islands being built 3m high
-buildings built raised on stilts
how will climate change affect agricultural systems
there will be changes in rainfall patterns, temperature, extreme weather events and pests and disease
what farming areas will be particularly affected by CC
low latitude farming areas growing food such as maize and rice in south east Asia
what is a method farmers can use to adapt to CC
irrigation systems
what will CC increase in temperature altitudes
-cereal production
-pests and disease
in higher temperature latitudes what will irrigation systems need to be installed for
-to cope with heatwaves and drought
