IB ESS HL 6.3.13 Hl Variation in Climate Perspectives Questions

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;
