falling. (As colder air os heavier)

✓~ - high plateau of East Antarctica is a desert with less than 50mm of
equivalent falling per year, this does not fall as snow but as tiny ice crystals in
the air.

What impact will climate changes have on Antarctica wildlife?
, ✓~ - parts of Antarctica are warming three times as fast as other parts of
the world
- Warner's seas impact the wildlife
- warming Antarctic could attract new species of animals and plants, creating
competition for life that is specifically adapted to icy temperatures
- emperor penguins who rely on sea ice could lose areas of their homes
- krill face challenges growing and reproducing in waters that are becoming more
acidic from absorbing carbon
- threats to wildlife like penguins and wales that rely on Krill as their main food
source
What impact will climate change have on Antarctica physical climate?
✓~ - warming climate contributes to ice/ glacier calving. If the ice shelf is
exposed to warmer air above or warmer water below, there will be more rapid
melting of the shelf.
- sea level rise is the most expensive consequence of global climate change, can
cause global flooding
- co2 released into atmosphere that is stored in ice sheets, which causes global
temperatures to rise more, enhancing global warming on Antarctica
, - albedo effect is lessens due to less ice sheets, meaning more heat is absorbed
into oceans
What are the 4 main threats to Antarctica?
✓~ - climate change
- fishing and whaling
- mineral exploitation
- tourism abs scientific research
What impact will fishing have on Antarctica?
✓~ - Antarctica is under threat from unsustainable fishing, which disrupts
the food chain of the environment
- overfishing removed viral animals in the already small food chain, such as
overfishing of krill which removes other marine animal food sources
- krill is the most fished marine animal and the majority is Antarctic krill
- despite regulations, there are still reports of illegal, unreported and
unregulated fishing
- the fishing is unsustainable and causes wide scale marine habitat damage
