Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental organisation that was established in 1988 as a part of the United Nations Environmental Programme (UNEP). It is a worldwide body that brings scientists, policymakers, researchers and others together to discuss and find solutions to climate change. The IPCC's mission is to educate the public about climate change and suggest possible solutions.
The Panel is composed of non-partisan representatives who have been appointed by the governments. These government representatives pick qualified scientists to represent their interests at IPCC meetings. They also recruit experts and draft reports. The Panel can also be populated by government scientists. This does NOT necessarily mean that the government endorses the views expressed by a scientist.
IPCC's structure includes three working groups that focus on different aspects of climate science. One group deals with the physical science, the other two deal with adaptation and mitigation. Each Co-Chair leads one of the working groups. Both Co-Chairs also belong to the IPCC Bureau. They assist the chair with the selection of authors, and in preparing for meetings.
The Working Group I, the first of these groups, focuses primarily on the physical science behind climate change and its consequences. It includes the Met Office Hadley Centre (one of the leading climate research centers in the world).
The Working Group II reviews the effects of climate changes on people and their ecosystems and suggests mitigation strategies. It includes the Australian Government, which contributes to IPCC decisions and manages DFAT Trust Fund.
Working Group III, which examines mitigation options and the economic and socio-economic impacts of climate changes, is the third working group. Its members include the World Bank and the United States Agency for International Development.
The IPCC creates reports through volunteer groups made up of hundreds scientists from all around the world. They examine scientific literature to make recommendations based primarily on new research. An IPCC assessment report is a comprehensive review of current climate change knowledge. A report can also be published in four parts.
A summary of the full IPCC report is called the Summary for Policymakers. This report is most appealing to journalists as well as the general public. The IPCC reports can be accessed by everyone and are reviewed regularly by many experts. The IPCC collaborated closely with communication experts and practitioners to prepare the Fifth Assessment Report.
IPCC held an Expert Meeting on Communication on February 16, 2016. IPCC adopted several recommendations for effective communication at the meeting. Some of these ideas were integrated into the IPCC's outreach activities as well as the IPCC site.
In September 2019, the IPCC published the Special Report of Ocean and Cryosphere under Changing Climates. The IPCC is working to prepare for the publication of the Sixth Assessment Report (6AR6). It provides a comprehensive review on current climate change knowledge. This report, as with previous assessment documents, will be distributed in parts.
FAQ
What is the current climate like? How is it changing?
The current state of the global climate is one of unprecedented change and uncertainty. Unprecedented levels of atmospheric carbon dioxide are causing temperatures to increase significantly, leading to droughts, heat waves, changing rainfall patterns, melting polar ice caps, ocean acidification, and rising sea levels.
These changes are already having a profound impact on ecosystems around the world, causing extinctions and disruption of habitats. They are also threatening lives and livelihoods for billions of people, especially those who live in areas with resource scarcity.
Increased average surface temperatures, which are caused by human activity, have led to an increase of extreme weather events, such as hurricanes or cyclones. This trend is expected to continue into the future as temperatures continue to climb.
Global climate change can have a wide range of effects, including rising food security and displacement caused by extreme weather or sea-level rise forcing communities to relocate. Climate change is also exacerbating existing social inequalities by disproportionately affecting marginalized communities that do not possess the resources or knowledge necessary for adapting effectively.
While there has been progressing in efforts such as reducing carbon emissions or renewable energy initiatives in some countries, we have yet to see meaningful action at a global level that would be necessary for mitigating these changes effectively. To prevent further destruction and devastation caused by climate change, all countries must work together to take immediate action and plan for adaptation in an ever-changing world.
What are some solutions to climate changes? And how effective do they work?
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: A wide range of technologies have been used to address climate change. These include renewable energy sources, such as solar or wind power. They provide reliable and clean energy with minimal impact on 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.
Making behavioral changes: Simple changes to routines can make a huge difference in reducing greenhouse gas emissions and limiting future climate disruption. Locally produced goods can reduce emissions and transport costs. By using active or public transportation to transport your goods, you optimize your use of resources and bring down costs and air pollution. Also, insulation can be more cost-effective and help reduce the dependence on gas boilers in heating your home.
Geo-engineering (GEO): This involves large-scale interventions into natural systems that may be too risky because of potentially unforeseeable consequences.
The effectiveness and efficiency of these solutions will depend on how many producers invest in green alternatives. However, incentives such as electric Cars play an integral part in incentivizing alternative solutions. Other than increasing consumer awareness about their utility over time, it is possible to mandate alternative solutions via policies measures. This requires regulatory bodies that are willing to engage players further. Although nontechnological approaches can work at one level; solving the global warming problem requires all parties.
What can we do to help the climate change process?
Climate change is due in large part to human activity. The Intergovernmental Panel on Climate Change(IPCC) states that humans are responsible more than 70% for global warming in the past 20 years.
Carbon dioxide is released into the atmosphere by burning fossil fuels like oil, coal, and gas. This will increase the atmospheric CO2 levels already present. It acts as a "greenhouse gases" by trapping heat in Earth's atmosphere, increasing temperatures even more. This results in higher ocean levels because Arctic ice mellows and causes weather patterns to change around the world, which can lead to severe storms, droughts or floods. These could impact food production and pose a threat to human health.
Deforestation. Trees that absorb atmospheric carbon dioxide from the atmosphere in photosynthesis will be effected by being cut down. Reduced forest cover can also increase albedo, which is the amount of reflected sunlight coming back into space. This reduces solar heat absorption at the surface of the earth and promotes global warming. Also, deforestation can lead to a decrease in local air quality and respiratory problems.
Farming: The animal agriculture industry contributes 14%-18% of total anthropogenic emissions of greenhouse gases globally every year. Because of its high methane content, animal waste emits large amounts methane into the atmosphere. Reducing your intake of animal products is an effective way to lower your greenhouse gas emissions. Nitrous oxide can also be released into our atmosphere. This creates smog that harms our respiratory system.
In conclusion, human activity has been drastically impacting our environment for centuries now, but with rapid advances made in technology such as renewable energy sources availability we have started turning our heads towards the future leaving behind carbon-emitting heavy industries results will soon start speaking themselves clearly when we leverage on technology through green innovation paving away toward eco-friendly efforts combatting climate change efficiently keeping everyone safe under prosperous nature purview.
What are the consequences of climate change for society and the environment?
Climate change has many impacts on society and the environment. Climate change has many environmental effects. These include rising global temperatures, increased extreme weather events and sea level rise. These changes could have serious consequences for humans, causing instability in communities, intensifying poverty, insect-borne illnesses, changing human migration patterns, and destroying essential habitats.
Already, climate change is having an enormous impact on the environment as well as societies around the globe. Global temperatures are expected to continue to rise and this will only get worse in the future.
One of the most widespread effects of climate change is the rising ocean levels due to melting of ice caps. This can lead to shoreline erosion and increased flood risk for coastal communities. Saltwater intrusion can also happen, affecting freshwater supplies to coastal regions of many countries.
Due to climate change, extreme weather phenomena such as heatwaves/droughts frequently occur across many countries in the world. These events lead to massive destruction of homes, businesses, and even the loss of whole communities. Additionally, severe storms pose additional risks due to flooding or landlides that can increase damage to infrastructure such roads and railways.
Also, wildfires due to climate change are occurring more often than ever. These fires can cause severe damage to habitats and the lives of people living close by.
Such drastic changes in living conditions often result in displacement or even refugee crises when people move away from their homes either voluntarily or involuntarily because their towns have become too dangerous or no longer habitable given their altered climate conditions against which they cannot cope adequately.
An increase in aridity means that dust storms can occur more frequently, making people with asthma and other respiratory illnesses like asthma particularly vulnerable. In addition, pest infestations are expected to increase significantly linked with higher temperature extremes - a phenomenon known as 'greenhouse bug' - leading to further damage to agricultural production that further affects global food insecurity numbers as fewer crops become available at worse nutritional qualities potentially bringing additional hardships upon marginalized populations already barely able make ends meet otherwise.
How are developing countries and communities affected by climate change?
Due to their limited access to healthcare and technology, developing countries and communities are especially vulnerable to the impacts of climate change. Changes in temperature, precipitation, and sea levels increase pressure on already scarce resources, with floods and droughts wearing away at already fragile ecosystems. Rising temperatures can result in a reduction in crop yields. This will be disproportionately detrimental to poorer communities who are facing food insecurity. Extreme weather events, such as hurricanes and heatwaves, can cause the destruction of infrastructures and displacement of people, which further perpetuates economic inequality.
Climate change will have long-term effects on resources, poverty, and health. This includes an increase in the number of vector-borne disease such as dengue fever or malaria. A rising sea level and extreme weather events will increase the risk of flooding, putting lives at stake in coastal areas that often lack the infrastructure or emergency services required to evacuate. Building resilience against these risks necessarily involves mitigating greenhouse gas emissions but may require other measures such as improved management of freshwater resources and better access to health facilities which assists with prevention strategies for diseases like malaria.
What is the current state of international efforts to address climate change?
The current international climate-change effort is moving forward with unprecedented momentum and unity. Countries all over the world are now working together to reduce emissions, improve resilience against impacts, as well as invest in renewable energy sources.
The Paris Agreement, which has galvanized global action and provides a framework for countries to establish voluntary targets to reduce their emissions, serves as a framework. The UN Framework Convention on Climate Change, (UNFCCC), provides political guidance and pilots new initiatives like 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.
There are many sectors and industries that are taking action in addition to policy development. Cities are making active transitions toward sustainable public transport systems, while society overall is adopting more sustainable lifestyles. Businesses are innovating technologies which reduce emissions, while investors move their capital from fossil fuels to renewables.
The OECD committee represents wealthy countries and has established common standards for reporting national climate action through the Common Reporting Framework, also called 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.
What role does climate change play in greenhouse gas emissions?
Climate change is influenced by greenhouse gases. They act as an invisible blanket that wraps around the Earth, trapping heat radiation and warming it. Without them, the Earth would be much colder today than it is today.
These greenhouse gases are created by human activity such as burning fossil fuels. As more heat enters the atmosphere from these activities, it leads to increased temperatures and extreme weather.
Carbon dioxide (CO2) is the largest greenhouse gas. This is due to fossil fuels like oil, coal, and gas. Important contributors are also methane and nitrousoxide (N2O), as well fluorinated gases (Fgases).
Due to human activities, the concentration of greenhouse gasses has increased dramatically since preindustrial time. This has led worldwide warming and increased temperatures in the oceans as well as all over the planet. It is also leading to changes such as intense storms and droughts; melting glaciers; and rising seas.
To avoid more damage from climate changes, humans must reduce their emissions by switching away from fossil energy to increase their use of renewable energy like solar and wind power. Reforestation and other agricultural practices can be used to absorb more CO2 from air. These actions will reduce the atmospheric concentrations and improve the environment for all living things on Earth.

How To
How to integrate sustainable practices into your everyday life to fight climate change
One way you can incorporate sustainable practices into your daily life is by reducing your consumption of resources such as food, clothes, and energy. Don't buy new items every single day. Instead, shop secondhand. Additionally, eating vegetarian meals once or twice a week can help reduce the amount of methane released into the atmosphere from livestock production. Turn off lights whenever you are leaving a room in order to conserve energy.
One way to combat climate change, is to decrease emissions from transportation sources like planes and cars by carpooling. We can also opt for renewable power sources such as solar panels in replacement of traditional fossil fuels to generate electricity at home. Supporting measures on the policy level that are promoting clean air regulations is also important in order for action on climate change to effectively happen. Engaging with others on issues such as plastic pollution and deforestation can be hugely beneficial, since it makes citizens more aware of the issue and encourages them to act.
