Final answer:
The IPCC is essential in analyzing and responding to global climate change, with a wide scientific consensus recognizing the role of human activity in this process. Greenhouse gases and the greenhouse effect are key factors in driving these changes, which are leading to efforts to mitigate and adapt to the environmental impacts.
Step-by-step explanation:
The Intergovernmental Panel on Climate Change (IPCC) is a pivotal organization in understanding and addressing global climate change. Established by the UNEP and the World Meteorological Organization, the IPCC's role is to evaluate the scientific research surrounding the climate changes our planet is undergoing.
These gases, through the greenhouse effect, trap heat within the Earth's atmosphere leading to a warming effect. Various international scientific organizations, including NASA and NOAA, support the IPCC's findings that climate change is real and primarily caused by human activities.
Statements claiming there is no scientific consensus on global climate change are often ideologically rather than evidence-driven, as a broad agreement on this issue exists within the scientific community. The efforts to address climate change include understanding and managing greenhouse gases, recognizing and adapting to altered weather patterns, and engaging in international agreements and accords to reduce emissions and stabilize climate impacts.
