Page "Robert Watson (scientist)" Paragraph 12

: The question is not whether climate will change in response to human activities, but rather how much ( magnitude ), how fast ( the rate of change ) and where ( regional patterns ).

It is also clear that climate change will, in many parts of the world, adversely affect socio-economic sectors, including water resources, agriculture, forestry, fisheries and human settlements, ecological systems ( particularly forests and coral reefs ), and human health ( particularly diseases spread by insects ), with developing countries being the most vulnerable.

The good news is, however, that the majority of experts believe that significant reductions in net greenhouse gas emissions are technically feasible due to an extensive array of technologies and policy measures in the energy supply, energy demand and agricultural and forestry sectors.

In addition, the projected adverse effects of climate change on socio-economic and ecological systems can, to some degree, be reduced through proactive adaptation measures.

These are the fundamental conclusions, taken from already approved / accepted IPCC assessments, of a careful and objective analysis of all relevant scientific, technical and economic information by thousands of experts from the appropriate fields of science from academia, governments, industry and environmental organizations from around the world.
