Question

conclusion for a project on 'human beings are responsible for climate change'

Answer 1

Answer:

International agreements on global environmental issues such as climate change should consider the principles of sustainable development proposed in Agenda 21 and the UNFCCC. These include the “precautionary principle”, the principle of “costs and responsibility” (the cost of pollution or environmental damage should be borne by those responsible), and “equity” – both within and between countries and over time (between generations).

Adherence to these principles would help prevent future global environmental threats and reduce existing ones. With climate change already underway, there is need to assess vulnerabilities and identify intervention/adaptation options (7). Early planning for health can reduce future adverse health impacts. The optimal solution, however, lies with governments, society and individuals – and requires changes in behaviour, technologies and practices to enable a transition to sustainability.

Answer 2

Answer:

A new development in the IPCC Fourth Assessment was the introduction of a chapter dedicated to observed and measurable impacts. The author team of this chapter examined more than 29 000 environmental data series and found that 89 per cent of these exhibited trends consistent with warming. Most of the available data are terrestrial, rather than oceanic, and are concentrated in Europe and North America, leading to dif­ficulties in drawing a global pic­ture. Nevertheless, the conclusion is that natural systems around the world are being affected by regional climate changes, particularly temperature increases, and that these temperature increases are very likely to be the result of anthropogenic emissions of greenhouse gases.
