Lucy Buxton: Okay, so we've got some time for questions now. Does anyone here have a question?
Lucy: Yeah?
Student: What will happen to countries with low land?
Lucy: That's a really good question.
If the icecaps continue to melt and if that causes quite a lot of sea level rise then low-lying countries like island nations in the Pacific,
for example, or areas around the coast, might be suffering from the water actually coming up onto the land and if there are buildings
very close in that zone then they may be covered by water too.
Alright, is there another question?
Yeah?
Student: What will happen to Australia in terms of global warming?
Lucy: Okay, well Australia is already a very hot and very dry country and what scientists are predicting that under conditions of global
warming we can expect it to get even hotter and even drier.
So that means that maybe our crops- the agriculture will suffer here- and also we can expect to have much longer hotter summers, so when
it was before it might've reached a maximum of 30 or 31 degrees might expect it to reach 34 or 35 degrees.

Lucy Buxton: Okay, so now I have a couple of questions from Hambledon.
This one is from Kayla. She asks: Is there really an ozone layer? And if there is, how can you prove it?
Well Kayla there is an ozone layer and the way that we can prove that is that scientists who study atmosphere
-the atmosphere and different gases- can take measurements of the gases at different levels in our atmosphere.
And ozone is actually a gas, so they can capture that gas and measure it and they have discovered that there is this really, really thin layer
of ozone surrounding our planet.
Our second question from Hambledon is from Madison and the question is, How long do you think it will take for all the Antarctic animals to die out?
Well that's a really, really difficult question to answer and there are a lot of scientists studying this at the moment.
But what we do know is that the icecaps are melting faster and faster and if that continues and if in the summer there is no ice at all in
the Antarctic or in the Artic then animals that live on the ice, like penguins for part of their lives or polar bears, won't have anywhere
to live and won't have anywhere to breed.
So I'm not an expert in this area but from the current research we can expect that to happen anywhere between the next 50 and 100 years
if the current trends in global warming continue.
