Viewpoint that human activity is contributing to global warming / we should be concerned [2 max] evidence from sediment/ice cores of human induced warming;
current rate of warming is unprecedented;
increase in greenhouse gas emissions from human activities (since Industrial
Revolution) correlates with increase in global temperature; evidence of dramatic affects of global warming in recent times eg melting of ice caps/shifting of biomes/extreme weather/coastal inundation/loss of biodiversity/social conflict; positive feedback loops could lead to exponential change/potentially devastating tipping points;
Viewpoint that human activity is not responsible for global warming / we do not need to be concerned: [2 max] part of natural cycles and not human induced; technology will provide solutions to any problems caused by global warming; prediction models of climate change/global warming are inaccurate; impacts are over exaggerated; global warming may be mitigated by negative feedback mechanisms; scientist are self serving and manipulate results to produce findings that attract funding for further research;
