The Intergovernmental Panel on Climate Change is an intergovernmental organization that was created in 1988 by the United Nations Environmental Programme. It is a multi-disciplinary body that brings together scientists and policymakers to discuss climate change. The goal of the IPCC is to educate the world about climate change risks and offer possible solutions.
The Panel is composed of non-partisan representatives who have been appointed by the governments. These government representatives select qualified scientists to represent them in IPCC meetings. Representatives recruit experts to help with the preparation of reports. Governments are also able to nominate their own scientists to serve on the Panel. This does not necessarily mean the government supports a scientist's views.
The IPCC structure has three working groups, each focusing on different aspects. One group deals with the physical science, the other two deal with adaptation and mitigation. Each of the working groups is led by a Co-Chair. Both Co-Chairs also belong to the IPCC Bureau. They provide advice to the chair regarding the selection of authors as well as the preparations for meetings.
The Working Group I is the earliest of these groups and focuses its attention on the physical science of climate changes and their impacts. It includes the Met Office Hadley Centre which is one of the top climate research centres worldwide.
The Working Group II reviews the effects of climate changes on people and their ecosystems and suggests mitigation strategies. Its members include the Australian Government, which manages the DFAT Trust Fund and contributes to IPCC decisions.
Working Group III, a third working group examines mitigation strategies and assesses the impact of climate-related changes on both the economic as well social dimensions. Its members include the World Bank and the United States Agency for International Development.
The IPCC reports are produced by volunteer groups that include hundreds of scientists from all over the world. They examine scientific literature to make recommendations based primarily on new research. A comprehensive review and analysis of climate change knowledge can be found in an IPCC assessment. A report can have four parts.
The Summary for Policymakers provides a summary from the full 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.
In February 2016, IPCC held an Expert Meeting on Communication. At this meeting, IPCC adopted a number of recommendations on how to communicate effectively. Some of these recommendations were incorporated into the IPCC's outreach activities and the IPCC website.
The Special Report on Ocean and Cryosphere Changes in Climate - September 2019 was released by the IPCC. 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. As with previous assessment reports, this report will be published in parts.
FAQ
How does climate change politics impact global efforts?
Climate change has become a highly politicized topic that has caused great divisions among governments, nations, and individuals. The implementation of measures to address climate change is affected by the political stances of various actors. It has become increasingly difficult to come to an agreement on how to address this urgent environmental crisis globally.
Scientific consensus is unanimous that human-caused climate change is real and needs to be addressed. These issues are often dominated by politics, which can hinder global cooperation that is necessary to implement sustainable energy practices, protect natural habitats, research viable technological solutions, as well as other climate change interventions.
Many governments in the world want to protect their economic interests, and enforce measures that limit business activities. This often conflicts with the regulations that experts recommend to address climate change efficiently. Without strong international commitments and wide-spread international action, it can be very difficult for any individual state or group of nations to address climate change effectively through legislation.
Differences in power dynamics among countries further complicate gaining full consensus on how best to tackle climate change. The countries with greater economic power tend to nominate their own representatives to represent them in international bodies that are responsible for the environment. This can lead to biased discussions between the perceived interests of the country and the collective interest of all parties. Additionally, the potential side effects of implementing radical changes like geoengineering are being heavily debated at both national as well international levels.
In the same way, grassroots movements are fighting powerful opponents at the grassroots level. These include corporate ownerships and well-funded lobbyists looking to retain politically favorable positions.
To mitigate the current environmental crisis, it will be crucial that resources are properly distributed and political divisions between countries are not overlooked.
What are the possibilities for new technologies to combat climate change?
This global problem is a huge challenge that new technologies can address. From renewable energy sources like solar, wind, and geothermal to energy storage systems like battery packs or thermal tanks, advances in applied science are making it possible for us to transition to a more sustainable future.
New methods of carbon capture and sequestration can be employed to draw down greenhouse gas levels, while enhanced agricultural practices can reduce emissions from livestock and soil degradation. Smart grid technology can also be used with existing power infrastructure for an efficiency boost, and improved building design can help minimize energy consumption.
In addition, cutting-edge synthetic biology approaches allow scientists to develop organisms that can utilize green sources of fuel such as CO2 laser into usable biofuel or alternate feedstock. If the market shifts away from petrol-based cars to zero-emission electric vehicles powered by clean sources, this could transform transportation.
Finally, increased investment in digital technology can empower people across borders with more access to data about their ecological footprints and allow them to make better decisions regarding their consumption habits. Understanding our role in carbon production will allow us to all be better stewards for our planet.
What is the impact of climate change on oceans and marine life around the world?
What will climate change do to the oceans and marine life of the world?
Since its inception climate change has significantly affected the world's oceans as well as the marine life associated with them. The depletion of the ozone layer, which causes constant oceanic warming, has caused major disruptions to marine ecosystems. This has led to coral bleaching and a decline in species.
Climate change can also be linked to unpredictable weather and stronger storms. This can cause extreme sea level rises that can prove fatal for coastal areas. Furthermore, changes in temperature may reduce oxygen levels in water systems resulting in "dead zones" where abundant marine life becomes sparse.
Ocean acidification can also be caused by climate change. Excess carbon dioxide is released into the atmosphere and accumulates in the oceans. Ocean acidification causes an increase in pH which affects the vital functions of animals such as crabs, clams, and oysters that cannot adapt to changing conditions.
Higher temperatures can also change the location or shrinkage of natural habitats, making them less suitable for some species. Ocean stress increases already high extinction rates worldwide, creating a severe imbalance of predators and prey which might lead eventually to complete extinction.
The effects of climate change ripple throughout entire ecosystems influencing multiple species whether directly or indirectly through evaporation lowering water volumes or sharp temperature shifts jeopardizing any sustainable development for fisheries and other maritime activities. Overall climate change continues one by one wiping out entire species from our planet transforming future lives on land but most importantly deep below the surface of our oceans.
What is climate Change and how does this happen?
Climate change is the long term shift in global weather patterns resulting from an increase of greenhouse gases. These gases trap heat in the atmosphere, which causes global temperatures rise. This leads to many changes in weather and climate. This could lead to rising sea levels, melting glaciers and extreme storms and dry spells, widespread coral reef bleaching, and the extinction of species.
The main cause of climate change is human activity such as burning fossil fuels for electricity and transportation, cutting down forests, and farming livestock. This is because these activities release huge amounts of carbon dioxide into the atmosphere. It warms the planet faster than natural processes like volcano eruptions.
The deforestation plays an important role in contributing approximately 15-20% to global greenhouse gas emissions. The atmosphere is effected by the carbon dioxide stored in trees when they are cut down or burned. Additionally, forests act a natural carbon source that absorbs CO2 into the atmosphere. Without this capacity, carbon dioxide levels in the atmosphere will continue to rise with devastating effects for ecosystems around world.
In addition to releasing CO2 into the atmosphere, human-caused pollution also emits other harmful gasses such as methane (CH4) and nitrous oxide (N2O). Methane has been extensively employed in industrial processes. It contributes significantly to the atmosphere's warming. While N2O can be emitted primarily by agricultural soil management activities, such as tilling or fertilization which release excess nitrogen to soil.
Humanity must work together across all levels of society, economy, and politics to reduce greenhouse gas emissions. We need to shift from dependence on fossil fuels and towards renewable energy sources like solar, wind, and low-carbon hydrogen fuels in order to limit climate change. A smart approach to reducing atmospheric contamination and preventing CO2 accumulation could be to replace polluting fossil-fuel technologies with ones that encourage zero-waste living. Reforestation projects, which are powerful aid in the fight against climate change by absorbing large quantities of CO2 back into nature and maintaining biodiversity, can help us take responsibility for our environmental impact.
What are the impacts of climate change on developing countries and communities?
Developing countries and communities are particularly vulnerable to the effects of climate change due to limited access to resources, healthcare systems, and technology. Changes in temperature and precipitation can put more pressure on already limited resources. This is accompanied by flooding and droughts that weaken already fragile ecosystems. Rising temperatures can lead to a decrease in crop yields, which will disproportionately affect poorer communities struggling with food insecurity. Extreme weather events like heatwaves or hurricanes can lead to destruction of infrastructure, displacement of people and further perpetuating economic inequality.
Climate change has long-term consequences. They will lead to continued resource scarcity, extreme poverty, and adverse health effects, including increased incidences of vector-borne illnesses like dengue fever and malaria. There will also be an increased risk of flooding from rising sea levels, combined with extreme weather events. This puts lives at risk in coastal locations where many people lack the necessary infrastructure and emergency services 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 status of international efforts to tackle climate change?
The international effort to tackle climate change has reached a new level of unity and momentum. Countries all around the globe are increasingly joining forces to find solutions to climate change.
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 is also providing guidance to policy and piloting innovative initiatives, such as carbon market mechanism.
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.
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.
These efforts demonstrate the importance of climate action. For any chance of reaching the climate goals set forth by science and international law, government, civil society, & private sector actors must build upon this momentum.
