Intergovernmental Panel on Climate Change (IPCC), an intergovernmental organisation, was established as part of the United Nations Environmental Programme in 1988. It is a global organization that brings together scientists, policymakers, and other people to discuss climate change and find solutions. IPCC's goal is to help educate the world about the risks of climate change and to put forward possible solutions.
The Panel is an impartial body made up of representatives from governments. These representatives are selected by governments to be scientists in the IPCC meetings. Representatives recruit experts to help with the preparation of reports. The Panel can also be populated by government scientists. This does not necessarily mean the government supports a scientist's views.
IPCC's structure consists of three groups that are focused on different aspects. One group focuses on physical science and the two other groups focus on adaptation or mitigation. Each member of each working group is led by a Chair. Both Co-Chairs are also members of the IPCC Bureau. They assist the chair in selecting authors and preparing for meetings.
The Working Group I, the first of these groups, focuses primarily on the physical science behind climate change and its consequences. Its members include one of world's most respected climate research centres, the Met Office Hadley Centre.
The Working Group II assesses the effects of climate change on people and ecosystems, and proposes measures to mitigate climate change. It includes the Australian Government, which contributes to IPCC decisions and manages DFAT Trust Fund.
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 is made up of the United States Agency for International Development (USAID), and other organizations.
Reports produced by the IPCC are prepared by volunteer groups of hundreds of scientists from around the globe. They evaluate scientific literature and make recommendations based on the latest research. An IPCC assessment is a complete review of climate change knowledge. A report can be published in 4 parts.
The Summary for Policymakers is a summary of the entire IPCC report. This report is typically most useful to journalists and the public. Everybody can access the IPCC report and they are reviewed by several experts. The IPCC worked with communication professionals and practitioners for the Fifth Assessment Report.
IPCC organized an Expert Meeting on Communication on February 2016. The IPCC made a variety of recommendations to improve communication. Some of these recommendations were implemented into the IPCC outreach activities and the IPCC web site.
The Special Report on Ocean and Cryosphere Changes in Climate - September 2019 was released by the IPCC. The IPCC is now preparing for the Sixth Assessment Report, (AR6). This report provides an extensive review of current climate-change knowledge. The report will be published as a series, just like the previous assessment reports.
FAQ
What does the role of greenhouse gases contribute to climate change?
Greenhouse gases are a key factor in climate change. They act as an invisible layer around the Earth trapping infrared radiation. This warms the atmosphere. Without them, the planet would be much colder than it is today.
Human activity can cause greenhouse gases, such as the burning of fossil fuels and other industries that emit emissions. These activities will continue to increase heat trapping in the atmosphere. This will lead to increasing temperatures and extreme weather conditions.
The most prevalent greenhouse gas is carbon dioxide, which is released from fossil fuels, such as oil, gas, and coal. Methane (CH4), nitrous oxide (N2O), and fluorinated gases (F-gases) are also major contributors to climate change.
Since preindustrial times, the concentration of greenhouse gases has risen significantly due to human activity. This has led worldwide warming and increased temperatures in the oceans as well as all over the planet. It is also causing drastic changes, such as increased storms, droughts, melting glaciers and rising ocean levels.
To reduce further damage caused by climate change, human beings need to decrease their greenhouse gas emissions. We can do this by shifting away from fossil fuels in favor of renewable energy sources like solar and wind power. There are also ways to reduce CO2 emissions, such as by planting trees and using agricultural techniques that absorb more of the gas. These actions will help reduce atmospheric concentrations in greenhouse gases and create a healthier ecosystem for all life.
What is the role of individuals and communities in addressing climate change?
Climate change is one our greatest contemporary challenges. It affects all of us and requires our collective attention as well as individual actions to make a real difference.
Individuals have an essential role to play in addressing climate changes and reducing their effects. It is possible to make small changes in your everyday life such as reducing waste or consuming more conscious, switching to vegetarianism, eating less meat, taking public transportation more often, and using more sustainable fabrics for clothing and home decor. They can also take part in advocacy and support initiatives that promote sustainability in their communities.
Communities are also key players in addressing climate change on a bigger scale. They can adopt policies that reduce emissions. These include reformulating energy models that are based on renewable sources, encouraging efficient infrastructure for bicycle or electric transport, reducing deforestation and encouraging composting systems for waste disposal. Collaboration between different communities across cities and countries is fundamental for achieving success in this mission.
Additionally, civic education about the dangers of climate change and ways to help it be tackled should be started in the very early stages of education. It should also be taught throughout lifelong learning opportunities. This will help individuals become aware of the issues at stake and understand our interconnectedness with other societies further away from our geographical location but similarly affected by global warming
Employers have a significant responsibility in combating climate change. Introducing corporate practices that are focused on sustainability and choosing green alternatives whenever feasible will undoubtedly result in positive economic and sociological outcomes.
Individual actions, community policies and business transformation can all be a part of creating solutions to global warming. Together they will help humanity avoid the longer term negative effects of climate change.
How does climate change impact marine life and oceans around the globe?
What is the effect of climate change upon the world's oceans?
Since its inception the climate change has had an impact on the world's oceans, and the marine life within them. Constant oceanic warming due to the depleted ozone layer causes drastic disruptions in marine ecosystems resulting in a decrease in species and coral bleaching.
Unpredictable weather conditions and stronger storms are also linked to climate change, leading to extreme surges in sea levels that can prove deadly for coastal areas. Temperature changes can also cause water levels to drop, causing "dead zones", areas where there is less marine life.
Ocean acidification is also caused by carbon dioxide that is released into the air and then accumulates in the seas. Ocean acidification can raise pH levels, making it difficult for animals to adapt like crabs, clams or oysters.
Higher temperatures can also cause changes in natural habitats. They may shrink or change their geographical location, making it unhabitable for species that depend on them. The increase in ocean stresses accelerates the already high rates of extinction worldwide. This can lead to a severe imbalance among predators and prey, which could ultimately lead to complete extinction.
The ripple effect of climate change affects entire ecosystems. It can directly or indirectly impact multiple species through evaporation, lower water volumes, and sharp temperature shifts. Climate change is transforming the future of all life forms on our planet, not just those living on land but those living below the ocean surface.
What is the current state of international efforts to address climate change?
The current state of international efforts to address climate change is one of unprecedented unity and momentum. International efforts to address climate change are being facilitated by countries around the world, who are increasingly working together to reduce carbon emissions, improve resilience and invest in renewable energies.
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. In addition, the UN Framework Convention on Climate Change provides political guidance as well as piloting new initiatives such carbon market mechanisms.
Other regions are seeing progress. The European Green Deal is a comprehensive legislation package that seeks to create a European economy with sustainability as its core. Countries on the African continent also have committed to The African Renewable Energy Initiative, which aims increase Africa's participation in global renewable energy production.
Action can also be seen across industries and sectors. Cities are moving towards sustainable public transport, while the whole society is adopting more sustainable lifestyles. Companies are developing technologies to reduce emissions, while investors shift their capital away fossil fuels in favor of 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.
All these efforts are a sign of the unprecedented importance given to climate action. If there is any hope of meeting the science-based Climate Goals, all stakeholders (governments, civil societies, and private sectors) must continue to build on their momentum and push for greater ambition & progress.
What is the relationship between climate change and extreme weather events?
Global warming has directly affected extreme weather phenomena such as heatwaves. Global warming has caused an increase of atmospheric temperatures.
According to climate scientists the average frequency for extreme weather-related events has increased more than twofold since 1980. Rising ocean water temperature causes sea levels to go up as well as changing wind patterns. This alters the normal distributions of storms, hurricanes, and other weather phenomena in different geographical areas around the globe.
The 2015 El Nino event brought warm water toward South America. It caused alarmingly high temperatures and heavy rains, which led to flooding in Peru. These floods resulted in displacement of people and property destruction. Several places including Antarctica have recorded their highest-ever temperatures indicating a definite relation between global warming trends and the occurrence or frequency of extreme weather events around the world.
Another example is Hurricane Irma in 2017. It caused $50 billion economic loss to Florida and other states, as well as Puerto Rico and Cuba. This is yet another proof that climate change is responsible.
The Intergovernmental Panel on Climate Change (IPCC) concluded that human activities are increasing the severity of current climate change which naturally leads to more frequent, severe, and intense natural disasters globally hence bringing forth strong evidence regarding humans' relation to extreme weather events occurring at frequent intervals around us all.

How To
How to integrate sustainable practices into your everyday life to fight climate change
You can implement sustainable practices in your daily life by reducing your consumption. Shopping secondhand and borrowing items from family and friends is a better option than buying new products every day. Eating vegetarian meals at least once a week can reduce methane emissions from livestock production. To conserve energy, it is a good idea to turn off all lights when you leave a room.
A second way to combat climate change is to reduce emissions from transport sources such as cars and planes by carpooling or using public transit instead. 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!
