Understanding the Question: Scientific View of Climate Change

The question asks to identify the specific organisation that provides an objective, scientific view on climate change, encompassing its natural, political, and economic impacts. This points towards a body focused primarily on synthesizing and assessing the existing scientific literature on climate change.

Analysing the Options

Let's examine each option to determine which one best fits the description:

1. International Union for Conservation of Nature (IUCN):

   IUCN is an international organization working in the field of nature conservation and sustainable use of natural resources. While its work is relevant to the impacts of climate change on biodiversity and ecosystems, its primary mandate is conservation, not providing the central, objective scientific assessment of climate change itself.

2. Intergovernmental Panel on Climate Change (IPCC):

   The IPCC is an intergovernmental body of the United Nations responsible for advancing knowledge on human-induced climate change. It assesses the scientific, technical, and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation. Its reports are widely considered the most authoritative assessments on climate change, based on the work of thousands of scientists worldwide. This description aligns very closely with the question's requirement for an "objective, scientific view".

3. United Nations Environment Program (UNEP):

   UNEP is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment. UNEP is involved in various environmental issues, including climate change, but it is not the specific body solely dedicated to providing the comprehensive scientific assessment of climate change like the IPCC.

4. The Climate Project (TCP):

   The Climate Project, founded by Al Gore, is an organization focused on educating the public about climate change and its solutions. It is primarily an advocacy and educational group, not a scientific body providing objective, comprehensive scientific assessments of climate change.

Identifying the Correct Organisation

Based on the analysis of each option, the organisation specifically mandated to provide an objective, scientific view of climate change and its various impacts by assessing existing scientific literature is the Intergovernmental Panel on Climate Change (IPCC).

The IPCC does not conduct its own research but rather assesses published scientific literature. Its reports are a crucial resource for policymakers to understand the current state of climate science and its implications.

Conclusion

The organisation that provides an objective, scientific view of climate change as also its natural, political and economic impacts is the Intergovernmental Panel on Climate Change.

Additional Information on IPCC and Climate Science

The Intergovernmental Panel on Climate Change (IPCC) is a key body in international efforts to combat climate change. Its assessment reports are compiled by hundreds of leading scientists who volunteer their time to review and synthesize the vast amount of research published globally. These reports are then subject to multiple rounds of review by experts and governments. This rigorous process aims to ensure the reports are comprehensive, objective, and policy-relevant, though not policy-prescriptive.

The reports cover various aspects, including:

• The physical science basis of climate change.
• Impacts of climate change, adaptation, and vulnerability.
• Mitigation of climate change (reducing emissions).
• Sometimes special reports on specific topics like extreme events or oceans and cryosphere.

These assessments are fundamental inputs for international climate negotiations, such as those under the United Nations Framework Convention on Climate Change (UNFCCC).
