ecology - global warming

Question 1

what is happening to earth’s temperature?

Answer 1

other scientist check others work before being published. checks for false claims

Question 3

what are the reports in popular media not subject to?

Answer 3

peer review so reporting on global warming can be oversimplified, inaccurate or biased

Question 4

how will global warming affect animals and plants?

Answer 4

• loss of habitats. ice leavers reduce causing population of arctic organisms to reduce
• animals and insects may extend their range northwards towards cooler conditions. example: mosquitos cant survive in cold conditions in UK however possible with global warming that range of these may spread to the UK which means diseases such as malaria will be brought with them
• species migrate/migration patterns will change
• affect plants, may flower earlier. grow grapes in part of UK that we can’t today if temp increases
• some parts of world, will be too hot to grow crops they need
