Intergovernmental Panel on Climate Change (IPCC), an intergovernmental organisation, was established as part of the United Nations Environmental Programme in 1988. It is a worldwide body that brings scientists, policymakers, researchers and others together to discuss and find solutions to climate change. IPCC's goal is to help educate the world about the risks of climate change and to put forward possible solutions.
The Panel is a non-partisan body composed of representatives appointed by governments. These government representatives pick qualified scientists to represent their interests at IPCC meetings. They also recruit experts and draft reports. A government can also nominate its own scientists for the Panel. This practice does not necessarily mean that the government endorses a scientist's views.
Three working groups are part of the IPCC's structure. They each focus on different aspects. One group works on the physical sciences, and the other two work on adaptation/mitigation. Each of the working groups is led by a Co-Chair. Both Co-Chairs are members of the IPCC Bureau. They assist the chair with the selection of authors, and in preparing for meetings.
The Working Group I, which is the first, focuses on the physical science and impacts of climate change. Its members include one of world's most respected climate research centres, the Met Office Hadley Centre.
The Working Group II studies the impacts of climate-related changes on ecosystems and people, and proposes mitigation measures. Its members include the Australian Government, which manages the DFAT Trust Fund and contributes to IPCC decisions.
The third working group, the Working Group III, examines mitigation options and considers the impacts of climate change on the economic and social dimensions. It includes the United States Agency for International Development, World Bank, and other organisations.
The IPCC produces reports by hundreds of scientists working together in volunteer groups. They examine scientific literature to make recommendations based primarily on new research. A comprehensive review of climate change knowledge is the IPCC assessment report. A report may be published in up to four parts.
The Summary for Policymakers is a summary of the entire IPCC report. This report is typically most useful to journalists and the public. All IPCC reports are open to the public and can be reviewed by a range of experts. For the Fifth Assessment Report, the IPCC worked with communications experts and practitioners.
IPCC held a February 2016 Expert Meeting on Communication. IPCC made many recommendations regarding how to communicate effectively at this meeting. Some of these recommendations were implemented into the IPCC outreach activities and the IPCC web site.
In September 2019, IPCC issued the Special Report On Ocean and Cryosphere in A Changing Climate. The IPCC is now preparing for the Sixth Assessment Report, (AR6). This report provides an extensive review of current climate-change knowledge. This report, as with previous assessment documents, will be distributed in parts.
FAQ
What role does the energy sector play in climate change? How can this be addressed?
The vital role played by the energy sector in climate changes is huge. The primary cause of global warming is the burning of fossil fuels. It releases carbon dioxide into our atmosphere and traps heat. This causes an increase of average temperatures.
To address this issue, energy sources must transition away from carbon-emitting fuels like coal and natural gaz and instead turn to renewable energy sources like solar, geothermal, wind, and other renewable sources. This can be achieved through incentives and government policies, but also by investing in new technology like hydrogen fuel cells. By investing in infrastructure that supports the use of these renewable sources, businesses and households can drive down emissions while simultaneously reducing their electricity bills.
Other ways include switching from polluting transportation options such as petrol-fueled cars to moving towards electric or public transport. The government has great power to help societies transition away from oil-based infrastructures. They can support research into battery technology and encourage consumers to invest in cleaner modes.
Companies must also adopt green business practices to reduce their carbon footprint. This includes installing better insulation in offices and implementing energy efficiency plans at production plants. This can dramatically reduce operational costs, while improving environmental performance metrics.
These initiatives should be championed at all levels, not just at company level but also at government. Raising taxes on pollution products encourages individuals and businesses to stop using harmful practices. While this may be a financial outlay for polluters, providing vouchers for or subsidy for low-carbon products can create a continuing market to support sustainability efforts. This is why tackling climate changes requires both private industry as well as private citizens to make a difference. By switching to green energy and adopting environmentally friendly practices, we can help to ensure that the future generations of people are affected positively.
How does human activity contribute to climate change?
Climate change is due in large part to human activity. According to the Intergovernmental Panel on Climate Change, humans have contributed more than 70% of global warming since mid-20th century.
Burning fossil fuels: Carbon dioxide is produced when fossil fuels, such as oil and coal, are burned. This increases the already high levels of atmospheric CO2, which acts as a greenhouse gas by trapping heat from Earth's sun and increasing temperatures. This causes higher ocean levels, as Arctic ice melts. It also scrambles weather patterns across the globe, leading to dangerous storms, droughts, floods and other problems that can affect food production and human health.
Deforestation - Trees which store atmospheric carbon dioxide within their trunks, when they absorb it through photosynthesis, are removed by deforestation. The albedo is also increased by cutting down forests. It refers to the amount of solar radiation reflected back into space. The deforestation of forests can also affect the local air quality, which is directly linked to respiratory problems.
Farming: Animal agriculture accounts for between 14%-18% worldwide's total anthropogenic greenhouse gas emissions. Large amounts of methane gas are released by animal waste due to its richness in methane bacteria. Eating less or none of these products can reduce global warming.
In conclusion, while human activity has had an adverse impact on our environment for centuries, technological advances have made it possible to turn our attention towards the future. We can leverage technology through green innovation to help us move forward in our efforts to reduce climate change and keep everyone safe.
How can the impact of climate change be reduced or mitigated?
There are various measures that can be taken to reduce and mitigate the effects of climate change. These include reducing greenhouse gas emissions through better energy practices and using alternative sources of energy such as renewable resources, employing more efficient agricultural techniques, improving land management practices, enhancing air quality laws, protecting forests and wilderness habitats, protecting against extreme weather events such as floods and droughts, investing in sustainable transport systems, strengthening early warning systems for disasters, beginning a research program on the impact of climate change on biodiversity and ecosystems, investing in green technologies such as solar panels or wind turbines, encouraging sustainable consumption habits, implementing suitable environmental regulations across all sectors of society. It's important that people are educated about climate change. This encourages them to take responsibility for their actions.
What are some of the proposed solutions to climate change and how effective are they?
Climate change has become one of the most urgent issues of our time. It requires government, businesses and citizens to pay attention. Rising temperatures, extreme weather events, increased sea levels, and melting polar ice are clear warnings of a disrupted climate system. Multiple solutions have been proposed to address this phenomenon. These solutions range from technological solutions to behavioral changes to geoengineering.
Technological Solutions: There are many technological solutions that can be used to combat climate change. These include renewable energy sources like solar power and wind power that provide reliable sources for clean energy while causing minimal harm to the environment. Electric cars powered with renewable energy could dramatically reduce pollution in cities and replace petrol vehicles. Other technological solutions include projects to increase carbon sequestration within trees and soil, as well coastal protection systems that protect vulnerable places from rising oceans.
Behavioral Changes: By making simple alterations to established routines can make a big difference in reducing emissions and limiting future climate disruption. For example, purchasing locally produced goods with shorter supply chains reduces emissions associated with transport costs for food. Public or active transportation can optimize the use of resources, reduce cost and pollution simultaneously. Similarly, more efficient insulation in homes can decrease dependence on gas boilers to heat homes. This will also help lower bills.
Geo-engineering (GEO): This involves large-scale interventions into natural systems that may be too risky because of potentially unforeseeable consequences.
The effectiveness of these solutions is dependent on how much producers will invest in green alternatives. Electric Cars are more costly than petrol versions, but economic incentives favoring these green solutions play an integral role. Incentivizing alternative solution use via policy measures is one step forward. However this requires regulatory bodies willing to engage the players further.
What are the current international efforts to combat climate change?
The current state of international efforts to address climate change is one of unprecedented unity and momentum. Countries around the world are increasingly collaborating on ways to reduce emissions, strengthen resilience against impacts, and invest in renewable energy sources.
At the global level, the Paris Agreement has galvanized collective action and serves as a framework for individual countries to set voluntary targets for reducing emissions. Additionally, the UN Framework Convention on Climate Change (UNFCCC) is providing political guidance and piloting new initiatives such as carbon market mechanisms.
Progress is also being made in specific regions; for example, The European Green Deal is a comprehensive package of legislation aimed at recreating Europe's economy with sustainability at its core, while countries of the African continent have committed to the African Renewable Energy Initiative which aims to increase Africa's share of global renewable energy production.
In addition to policy developments, action can be seen across sectors and industries; cities are actively transitioning toward sustainable public transport systems while society as a whole is embracing more sustainable lifestyles; companies are innovating technologies that drive down emissions while investors are reallocating their capital away from fossil fuels towards renewables.
The OECD committee has adopted common standards to report national actions on climate change by rich countries. This is known as the 2021 Guidelines.
These efforts all signify an unprecedented importance placed on climate action. Governments, civil society & private sector stakeholders alike must continue to build upon the momentum and push towards even greater ambition & progress if there is any hope of meeting Climate goals set by science & enshrined in international law.

How To
How to include sustainable practices in your daily life to combat climate changes
You can implement sustainable practices in your daily life by reducing your consumption. Don't buy new items every single day. Instead, shop secondhand. In order to reduce the amount methane in the atmosphere, it is a good idea to eat vegetarian meals only once or twice per week. Finally, whenever possible, turn off the lights when leaving a room to conserve energy.
You can also reduce the emissions from transportation sources such as cars, planes and trucks by using carpooling and public transit to transport your passengers instead of driving. Solar panels can also be used as a renewable power source to produce electricity at home, replacing traditional fossil fuels. It is crucial to support measures at the policy level that encourage clean air regulations in order to make climate change mitigation work. It is also a great idea to engage with others about issues like plastic pollution and forest destruction. This creates more informed citizens who will take action!
