A scientific consensus is an opinion or general judgement about a topic. The consensus that Earth has been warming is the best. Human activities, such as burning fossil fuels, have warmed Earth's ocean basins, and shifted Earth's climate. This does not mean all scientists agree. Some groups, such as the American Association of Petroleum Geologists and the National Academy of Sciences, hold non-committal positions. However, many elected officials disagree with the dominant view.
A new study of over 88,125 climate related studies has shown that there is a solid consensus. Although it may not be the definitive answer to the question, this survey shows that the public is more likely believe a well-researched assertion that is supported by empirical evidence.
The consensus is based on the fact that humans have been influencing the climate for some time. The results of many studies that have been conducted over the past decades support this assertion. In other words, the consensus is that the human race is responsible for much of the global warming seen today. The likelihood of global warming spreading to other regions of the globe will increase as carbon emissions continue increasing.
Skeptics, however, have underestimated the consensus level. The overwhelming majority of scientists are in agreement with this view. There is a plethora of evidence that supports the hypothesis that man-made climate change is the dominant force in the Earth's climate. It is possible that scientists could find other factors that affect our planet's temperature.
To find the truth, you need to do your research. NASA Global Climate Change, for example. It's a compilation of citations taken from peer-reviewed research papers by various research groups across the globe. It highlights the quality science being conducted at NASA and shows how well it can address climate-related issues.
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 the keywords "skeptical", which included cosmic rays as well as natural cycles and solar panels. Some of these were high up on their list.
Let's look at the latest poll by Pew Research Center. The poll results showed that just half of respondents believe there has been a scientific consensus. Although the name is not exactly a secret, only 19 percent of Americans have a firm grasp of the scientific consensus on global warming, which is a shame given that this is a serious problem that needs to be addressed.
FAQ
How does climate change affect the world's oceans and marine life?
What is the impact of climate change on the world's oceans and marine life?
Since its inception, climate change has had a significant impact on the oceans and marine life of the world. The loss of the ozone coating and constant oceanic temperature increase causes significant disruptions in marine ecosystems.
Climate change also causes unpredictable weather conditions and stronger storms. These extreme surges can be deadly for coastal areas. Also, rising temperatures can reduce the oxygen levels in the water system, leading to "deadzones" that are areas with less marine life.
Climate change is also contributing to ocean acidification, caused by excess carbon dioxide released into the atmosphere that accumulates within the oceans. Ocean acidification can raise pH levels, making it difficult for animals to adapt like crabs, clams or oysters.
Higher temperatures can also change the location or shrinkage of natural habitats, making them less suitable for some species. This increase in ocean stress accelerates already high extinction rates amongst many species worldwide causing a severe imbalance between predators and prey that might eventually lead to complete extinctions.
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. 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 are the causes of climate change?
Climate change, which is a global phenomenon, has been driven by an increased amount of greenhouse gases from human activity. The increase was primarily caused by fossil fuel burning to generate electricity and transport. These emissions trap more sun's heat, causing global temperature rises.
Climate change is also caused by other factors, such as population growth and land clearing. This further reduces the number of naturally occurring carbon sinks that absorb CO2 from the atmosphere. Natural forces such as changes in solar radiation can also contribute to climate change.
These combined human activities result in overloading Earth's capacity to properly balance its energy budget, leading to an average increase of 1 degree Celsius globally since pre-industrial times. Glaciers melt quicker than they form, and sea levels rise because oceans absorb most the heat energy. Water scarcity, droughts, or extreme weather events such hurricanes and floods can also have devastating consequences.
We must reduce our carbon footprint, and begin reducing our emissions immediately to protect ourselves from the increasing impacts of climate change. It is crucial to reduce our dependence of fossil fuels for electricity generation and invest in renewable sources, such as wind turbines/solar panels. These do not emit any harmful chemicals into the environment. Other sustainable practices like reforestation can also help restore some balance around these delicate planetary cycles we rely on for survival.
What is the status of international efforts to tackle 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.
The Paris Agreement has energized collective action at the global level and is a framework that allows individual countries to set voluntary emissions reduction targets. The UN Framework Convention on Climate Change is also providing guidance to policy and piloting innovative initiatives, such as carbon market mechanism.
Also, progress is being made in particular regions. The European Green Deal is an extensive package of legislation that aims at recreating Europe’s economic system with sustainability at its core. Meanwhile, countries on the African continent have committed themselves to the African Renewable Energy Initiative. This initiative aims to increase Africa’s share of global renewable power 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 signify a new level of importance for 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.
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 in atmospheric temperatures. This has had an impact on different weather phenomena worldwide.
According to climate scientists the average frequency for extreme weather-related events has increased more than twofold since 1980. As sea temperatures rise, so do wind patterns. This alters the normal distributions of storms, hurricanes, and other weather phenomena in different geographical areas around the globe.
2015 El Nino brought warm water towards South America. This led to increasing temperatures at an alarming pace and heavy rains that caused floods and displacement in Peru, Bolivia and other countries. Many places, including Antarctica has recorded its highest temperature ever. This is an indication of a strong correlation between global warming trends & the occurrence/frequency of extreme weather phenomena around the globe.
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 concluded that humans are increasing the severity and frequency of climate change. This naturally leads to more severe, frequent, and intense natural catastrophes worldwide. It also provides strong evidence about human involvement in extreme weather events that occur at regular intervals around us all.
What are the implications of climate change for the environment and society?
Climate Change can have broad impacts on society as well as the environment. Climate change will have many impacts on the environment. 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 disruption is already having profound impacts on the environment and society around the world. As global temperatures continue to rise, this is likely to worsen in the near future.
Ocean levels rising due to melting ice caps is one of the most pervasive effects of climate change worldwide. This causes shoreline erosion along many coastlines and increases the risk of flooding for coastal communities. Saltwater intrusion is also a problem, and can negatively impact freshwater supplies along the coasts of many countries.
Climate change is causing extreme weather events like heatwaves, droughts and other severe weather to occur in many countries. These extreme weather events can cause widespread destruction of homes and businesses. In some cases, they lead to the displacement or relocation or even complete destruction of entire towns. Intense storms increase the risk of flooding and landslides. This can further damage infrastructure like roads, railways, and bridges.
Wildfires caused by climate change also increasingly occur more frequently than they did before with devastating results both for habitats and people living nearby who may find their lives at risk due to poor air quality when these fires spread smoke across affected areas.
These drastic changes often lead to displacement or refugee crises. People move out of their homes involuntarily or voluntarily when their communities become unsafe or uninhabitable due to the altered climate.
Dust storms are also increasing in severity worldwide due to increased aridity. This makes it more difficult for asthma sufferers and other respiratory conditions. Additionally, pest infestations are likely to rise significantly in conjunction with higher temperature extremes (a phenomenon known as the "greenhouse bug") which can cause further damage to agricultural production. This could further affect global food security numbers. As fewer crops become available at poorer nutritional qualities, it may bring additional hardships on marginalized communities already struggling to make ends meets otherwise.
What's the current climate in the world? And how does it change?
The global climate is currently experiencing unprecedented uncertainty and change. Unprecedented levels in atmospheric carbon dioxide are causing global temperatures to rise significantly. This can lead to droughts and heat waves as well changing rainfall patterns, melting Polar ice caps, ocean acidification and rising sea levels.
These changes already have a profound effect on ecosystems all over the globe, causing habitat destruction and extinctions. They are also threatening lives and livelihoods for billions of people, especially those who live in areas with resource scarcity.
Due to the higher average surface temperatures due to human activity, extreme weather events like hurricanes, cyclones and wildfires have been steadily increasing over time. This trend is expected to continue into the future as temperatures continue to climb.
The effects of a rapidly changing global climate can be felt everywhere from rising food insecurity to displacement from extreme weather events or sea level rise forcing communities to relocate. Climate change is also creating social inequalities bydisproportionately affecting marginalized populations that don't have the knowledge and resources necessary to adapt.
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.

How To
How to Support Climate-Friendly Businesses and Policies
Individuals can take several actions to support climate friendly policies and companies. This can include speaking out against non-climate-friendly businesses or politicians, voting for pro-environment candidates, writing letters or emails of encouragement to those who are already taking positive action towards the environment, and signing petitions in favor of policies that encourage and support climate-friendliness. Individuals can also choose to switch providers to companies with a better environmental record, or opt for sustainable products over ones with higher carbon emission.
Reducing one's own carbon footprint is an important step in supporting climate-friendly policies and companies. This can involve changing simple daily habits such as unplugging appliances or switching off lights when not needed, commuting via public transportation or carpooling instead of driving alone, using eco-friendly household items like biodegradable cleaning supplies and composting kitchen scraps rather than adding them to landfills, wearing clothes made from sustainable fibers often grown without chemicals, choosing locally sourced food whenever possible, setting up energy-efficient energy systems at home using solar panels or wind turbines, and planting trees around your property which absorb CO2 (carbon dioxide) from the atmosphere.
Before investing, investors who are interested in climate-friendly policies should look for companies that emit less carbon. They should review their portfolios on a regular basis to make sure that they are meeting the sustainability standards they have set. Green bond investors might want to make sure that they don't finance activities that cause more greenhouse gas emissions than they remove. Investors should look out for opportunities to use funds towards green business activities. This includes renewable energy alternatives, community-building projects, and initiatives that promote sustainability.
