global warming

Methane and carbon dioxide trap heat in the atmosphere owners ( greenhouse gases) this is leading to global warming .

Humans s have released huge amounts of carbon dioxide into atmosphere this is mainly due to burning of fossil fuels such as coal and oil.

Methane is produces by bacteria is paddy fields which are used to grow rice. And when cows pass wind.

Peer review is when scientific papers about global warming are checked by other scientists before being published. Peer review helps detect false claims and makes sure that research published in scientific journals is valid.

However reports in the popular media e.g newspapers are not subject to peer review.

This means reporting on global warming can sometimes be oversimplified, inaccurate or biased.

The temperature of the earth is increasing so how will this affect animals and plants?

loss of habitats - reduction in ice levels in the arctic this will cause populations of arctic organisms e.g polar bear to fall as their habitat is reduced.

Global temperatures rising - birds and insects may gradually extend their range towards cooler conditions. Mosquitos cannot survive the cold conditions of the uk however it is possible that with global warming , the range of these insects may spread to the uk and diseases such as malaria may be brought with them.

-With global warming the migration patterns of lots of different animals may change

-Global warming can also affect plants for e.g in the uk spring plants are flowering earlier due to warmer conditions.

-As temperatures increase , we may be able to grow crops such as grapes in parts of the UK where we cannot today.

• in other parts of the world it may too hot to grow the crops that need.
