A scientific consensus refers to a general opinion or judgment about a subject. The consensus that Earth is warming is the best example. Burning fossil fuels and human activities have warmed the oceans of Earth, and changed Earth's climate. However, this does not mean that all scientists agree. Many groups, including the American Association of Petroleum Geologists (NAPS) and the National Academy of Sciences (NAS), hold non-committal posts. Among elected officials, however, there are dozens who deny the prevailing view.
A new study of more than 88,125 climate-related studies suggests that a solid consensus is indeed a thing. This survey does not prove that there is a definitive answer. However, it does show that public trusts well-researched, empirically supported and objective statements over those made to favor one side.
The consensus is based on the fact that humans have been influencing the climate for some time. Many studies done over the last few decades have supported this conclusion. The consensus is that global warming is largely due to human activity. As carbon emissions increase, the chances of global warming spreading will also increase.
The skeptics are also doing a great job of underestimating consensus. In fact, there is no doubt that the vast majority of scientists agree with the prevailing viewpoint. There is a plethora of evidence that supports the hypothesis that man-made climate change is the dominant force in the Earth's climate. Scientists could also find other factors that impact the temperature of our planet.
To find the truth, you need to do your research. NASA Global Climate Change is a good example. It is a compilation from peer-reviewed papers from various research organisations around the globe. Specifically, it demonstrates the quality of science that is being carried out at NASA, and it illustrates how well the agency is able to address questions about climate.
Skeptical Sciences also conducted a study that analyzed over 12,000 peer review abstracts on global heating. The study found that more than 97% of these papers agreed with the most commonly cited "skeptical" proposition: that human activity is largely responsible for the rise in average temperatures. What's more, the paper's authors were not naive. They used an algorithm to search for the "skeptical" keywords including cosmic rays, natural cycles, and solar panels. Some of these were near the top on their list of most interesting citations.
Let's lastly take a look to the recent Pew Research Center poll. The results show that only half of Americans believe or know there is a scientific consensus on the subject. It is not hard to find the name, but only 19% of Americans know the scientific consensus about global warming. This is a serious problem and must be fixed.
FAQ
How does climate change affect extreme weather events?
Global warming is directly connected to extreme weather events such a heat wave, floods or droughts, cyclones storms, hurricanes, and cyclones. Global warming has caused an increase of atmospheric temperatures.
Climate scientists say that the average frequency of extreme weather-related disasters had more than doubled since 1980. Sea levels rise as a result of changing wind patterns and ocean temperatures. This has an impact on the normal distribution and strength of hurricanes and storms across different regions of the planet.
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. Many places, including Antarctica had their highest-ever temperatures. This suggests a connection between global warming trends or the occurrence or frequency in extreme weather events.
Another example is Hurricane Irma. In 2017, it caused $50 billion of economic losses not just in Florida, but also in other states like Puerto Rico, Cuba and Puerto Rico. This shows that climate change is responsible again for the dramatic rise in major storms.
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 does climate politics affect global efforts for its resolution?
Climate change is highly politicized and has caused division between governments, individuals, and nations. Politics of different actors can have an impact on the implementation of climate change measures. It has been difficult for global consensus to address this urgent environment crisis.
Most scientists agree that humans are causing climate change. This is why it is urgent to act. These issues are often subject to political interference that can hamper global cooperation in order to implement sustainable energy practices, preserve natural habitats, find viable technological solutions and other interventions related to climate change.
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. It is very difficult for any one state or group of countries to effectively address climate change without strong commitments from all participants and broad-scale international action.
Different power dynamics can make it difficult to achieve full consensus on the best ways to address climate change. Countries with greater economic power are more likely to elect their own representatives to the international bodies responsible for negotiations on the environment. This can cause lopsided discussions about the interests of each country versus the collective interest all parties. At both the national and international level, there have been extensive discussions about potential side effects of radical changes like geoengineering.
A grassroots movement has also struggled against powerful opposition, including corporate ownerships as well-funded lobbyists trying to keep their industries politically favorable. This is especially true when it comes funding research into alternative energy production and enforcing mandates for renewable energy technology. Individual governments need to be clear about the potential rewards and outcomes of making valid progress on the issue. They cannot seek short-term spectacles or gains to gain public support.
To mitigate the current environmental crisis, it will be crucial that resources are properly distributed and political divisions between countries are not overlooked.
What role do greenhouse gases play in climate change?
Greenhouse gases play a major role in climate change. They act as an invisible layer around the Earth trapping infrared radiation. This warms the atmosphere. 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. These activities increase the heat that is trapped in the atmosphere. This leads to higher temperatures and more extreme weather events.
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).
The concentration of greenhouse gases has increased significantly since preindustrial times due to human activities. This has led to global warming and an increase in temperatures all over the world, as well as in our oceans. It is also causing major changes such as stronger storms and more droughts, melting of glaciers, rising sea levels, and increased flooding.
To prevent further climate change-related damage, humanity must reduce its greenhouse gas emissions by moving away from fossil fuels and towards renewable energy sources like wind or solar 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.
What are the international efforts currently being made to address climate change
The international effort to tackle climate change has reached a new level of unity and momentum. 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 and (UNFCCC) provides political guidance, as well as piloting initiatives such a carbon market.
There are also progresses in certain regions. For example, the European Green Deal, a comprehensive package aimed at recreating Europe’s economy with sustainability at the core, and the African Renewable Energy Initiative, which targets increasing Africa's share in global renewable energy production, is being implemented.
Apart from policy changes, action is visible across sectors and industry. Cities are actively transitioning to sustainable public transport systems. Society at large is adopting more sustainable lifestyles. Companies have been innovating technologies to lower emissions. Investors are switching away from fossil fuels to invest in 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 of these efforts show an unprecedented focus on 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.
