Climate Change - Van de Wal

7 important questions on Climate Change - Van de Wal

Explain what the IPCC does and what not?

The Intergovernmental Panel on Climate Change The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. To assess scientific knowledge on climate change:


  • Does: organizes writing, determines which reports when, table of contents (by means of the scoping process), sets rules on how to make the report, approves the reports.

  • Does not: prescribe research (based on existing literature) and prescribe content

What do we mean by detection and attribution in the context of the IPCC?

Detection of climate change is the process of demonstrating that climate has changed in some defined statistical sense without providing a reason for that change (Quantative)

Attribution of causes of climate change is the process of establishing the most likely causes for the detected change with some defined level of confidence.(Qualitative)

How does the IPCC work, and what is the ultimate goal?

  • Scoping > approval of outline > nomination of authors > selection of authors > expert review (1st order draft) > government and expert review (2nd order draft) > final draft report and SPM > government review of final draft SPM > approval and acceptance of report > publication of report



Ultimate goal: Provide information about climate change to inform policymakers, scientists and citizens by providing a comprehensive report and assessment that is as neutral as possible

Mention three aspects of climate change adaptation that the IPCC discusses

Climate change adaption:
  • Adaptation is unevenly distributed
  • Adaptation is feasible but needs social/institutional support
  • If we focus on adaptation we forget about prevention

What are the conclusion about GHG emissions

GHG Emissions
  • Climate resilient development prospects are increasingly limited if current GHG emissions do not rapidly decline.
  • Prospects constrained by past development, emissions and climate change
  • Enabled by inclusive governance and resources, information

What is the link between Sustainable Development, vulnerability and climate risks?

Sustainable development meets present needs without compromising future generations. Climate risks harm vulnerable populations; addressing them is crucial for sustainable development. Without adaptation and mitigation strategies, climate risks can reverse progress, exacerbating poverty and inequality. Integrating climate risk management into sustainable development ensures a more resilient and equitable future.

How cab industries and urban settlements reduce GHG emissions

Innovations, investments, and behavioral changes can reduce energy usage. Changing service models and behaviors can also help.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
