result in the greenhouse effect.
The greenhouse effect: Thermal radiation from
the sun is absorbed by
atmospheric greenhouse gases, and is

Sea levels
If the sea levels rise by 60m the whole
of New Jersey and New York will be
underwater and in the UK London
and the whole of the East around
Cambridge will be underwater. In
Europe, the majority of Denmark and
low lying countries like the
Netherlands would be underwater.
This is a global effect of global

Sea level rise
Nationally and locally a
sea level rise of 7m
would begin to affect
us quite dramatically as
parts of London would
be underwater
Also the Fens would be massively
affected along with the Humber and
North Eastern area as major cities
like Hull, Doncaster, Scunthorpe and
Peterborough would all be
underwater.…read more

predominantly where the Thames flows through, like our local area of
Reading .…read more
