A scientific consensus is an opinion or general judgement about a topic. The best example is the consensus that Earth is warming. Human activities, such as burning fossil fuels, have warmed Earth's ocean basins, and shifted Earth's climate. However, not all scientists agree. Indeed, some groups such as the National Academy of Sciences and the American Association of Petroleum Geologists hold non-committal positions. There are however many people who don't agree with the current view of elected officials.
A new study of over 88,125 climate related studies has shown that there is a solid consensus. The survey may not provide the definitive answer but it does show the public is more likely than others to believe an objective, well-researched, empirically backed, and impartial assertion.
The consensus rests on the fact humans have had an influence on climate since the beginning of time. The results of many studies that have been conducted over the past decades support this assertion. In other words, it is clear that humankind is the main cause of much of today's global warming. As carbon emissions increase, the chances of global warming spreading will also increase.
Moreover, the skeptics have done a good job of underestimating the level of 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 may also be able to find other factors that are affecting the planet's temperature.
It is best to look at the research to find out the truth. NASA Global Climate Change, for example. It is a compilation citations from peer reviewed research papers from different research organizations around the world. It is designed to demonstrate the quality of NASA science, and how the agency can address questions related to climate.
Skeptical Sciences also conducted a study that analyzed over 12,000 peer review abstracts on global heating. The study found more than 97% supported the most frequently cited "skeptical" assertion that human activity was responsible for the rise of average temperatures. What's more, the paper's authors were not naive. They searched for the "skeptical keyword" using an algorithm, which included natural cycles, cosmic rays, and solar panels. Some of these were at the top of their list for the most interesting citations.
Let's finally take a look the Pew Research Center's latest poll. According to the results, only about half of the public actually knows or believes that a scientific consensus has been reached on the subject. While the name may not be a surprise, only 19% believe that there is a scientific consensus on global climate change. This is a grave problem that must be addressed.
FAQ
What are the effects of climate change on 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 can have serious implications for human populations, creating instability in communities, intensifying poverty and insect-borne diseases, altering human migration patterns, and destroying vital habitats.
Already, climate change is having an enormous impact on the environment as well as societies around the globe. As global temperatures rise, it is likely that this trend will continue in the near future.
One of the most prevalent effects of climate changes worldwide is the rise of ocean levels as a result of melting ice cap. This leads to shoreline erosion at many coasts as well as an increased risk for flooding for coastal communities. Also, saltwater intrusion occurs, which negatively affects freshwater supplies in coastal areas in many countries.
Climate change is causing extreme weather events like heatwaves, droughts and other severe weather to occur in many countries. These events result in mass destruction of homes or businesses and can lead to relocation or complete loss of life. 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.
This drastic change in living conditions is often a result of displacement or even refugee situations. When people decide to leave their homes, either involuntarily or voluntarily, it can be because their town has become too dangerous or not habitable due the changed climate conditions.
The increase in aridity causes dust storms to become more frequent, which makes people suffering from asthma and other respiratory ailments such as asthma even more 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.
What are the causes for climate change
Climate change has become a global problem due to an increase in human-generated greenhouse emissions. These gases are mostly emitted by fossil fuel combustion for electricity and transportation. These emissions cause more of the sun's warmth to be trapped in Earth's atmosphere, leading to rising global temperatures.
Other factors contributing to climate change include population growth, land clearing and destruction of ecosystems, deforestation, energy consumption, and over-grazing. This further reduces the number of naturally occurring carbon sinks that absorb CO2 from the atmosphere. Climate change can also come from natural forces, such as changes in solar energy.
These human activities combined result in Earth being unable to adequately balance its energy resources, which has led to an average global temperature increase of 1 degree Celsius from pre-industrial times. Glaciers are melting faster than they become and sea levels are rising as the oceans absorb most of the heat energy. Other negative consequences include water scarcity, droughts and extreme weather events like flooding and hurricanes.
It is vital that we reduce our carbon footprint immediately and stop releasing greenhouse gases. This will help us protect ourselves against further damage from climate change. It is vital to reduce our dependency on fossil fuels for electricity production. Additionally, invest in renewable resources such as solar panels or wind turbines. These sources are not harmful to the environment. These delicate planetary cycles are also susceptible to other sustainable practices, like reforestation.
How does climate change affect extreme weather events?
Extreme weather events, such as heat waves, floods, droughts, cyclones, storms, and hurricanes are directly linked to global warming. Atmospheric temperatures have increased due to global warming which has affected different weather phenomena on a global scale.
According to climate scientists in 1980, extreme weather-related natural disasters have increased by more than twice the rate. As sea temperatures rise, so do wind patterns. This impacts the normal distribution of storms or hurricanes in different areas across the globe.
The 2015 El Nino event pushed warm water toward South America resulting in rising temperatures at an alarming rate along with heavy rains that triggered floods in Peru and Bolivia resulting in the displacement of people and property damage. 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 which took place in 2017 causing $50 billion of economic loss not just to the USA's Florida but also to other states such as Puerto Rico, Cuba, etc proving once again that climate change is responsible for a dramatic increase in major storms.
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 is the impact of climate change on biodiversity and ecosystems?
Climate change can have a variety of impacts on biodiversity, ecosystems, and the environment. The most pressing issues facing wildlife and ecosystems are rising temperatures, extreme weather events, sea level rise, and increased acidity.
Changes in climate can lead to shifts within habitat areas, disruptions in food chains, or changes in population numbers, or both. This could have dramatic implications for biodiversity and ecosystem functioning. Changes in the hydrological cycles can also have an impact on water availability for species that live in aquatic environments.
Climate change also causes rising temperatures, more frequent extremes like droughts and flooding. This puts additional stress on fragile systems like coral reefs and tropical rainforests. It is estimated that up to 30% of animal species could become extinct due to climate change by 2050, which would spark a cascade of further losses within ecological communities.
Climate change is therefore a considerable threat not only to biodiversity but also to human societies that depend on functioning ecosystems for food, fresh water, timber, and other services. You can mitigate the effects of climate change at all levels by reducing global warming trends. Further, future damages can be prevented with good management practices.

How To
How to educate your community about climate change and mobilize action
Climate change education can be in many forms, from online resources and interactive educational tool to classroom activities, simulations, experiential learning programs, and classroom activities. The key elements of effective climate change education are:
-
The goal is to provide practical knowledge and skills for the people who are interested in this subject.
-
demonstrating ways that individuals can make a difference
-
Engaging participants in an open discussion about possible solutions
-
inspiring action through shared experiences
Educators will be able, through comprehensive lessons on climate change that are accessible to both students and adults, to help their communities create strategies for reducing their environmental footprint.
It is also possible to connect scientific research with real-world examples, which can be a unique way of engaging audiences in meaningful dialogue. Participating in case studies and learning from best practices provides the opportunity to see positive results firsthand. This can encourage further innovation or replicateable actions within their own organizations.
Participants are empowered by incorporating action-oriented activities in educational curriculums. This gives them the mental tools needed to create campaigns, petitions, and take local actions. It also allows them to be agents for social and political change or sustainability improvement initiatives. Moreover, emphasizing individual agency highlights the importance of participation in reducing emissions while also demonstrating participants' collective contributions towards a larger outcome. A key element in policy-making is to involve stakeholders as early as possible. This encourages their active involvement at every stage of the process and could result in better outcomes for all. Through concerted efforts at increasing public understanding of the impacts of climate change coupled with taking appropriate action on mitigating greenhouse gas emissions, we might be able to create an environment where these pressing matters are addressed urgently with attention applied where necessary most so that together we may one day be able to ensure successful implementation measures that will help us reach our collective goals out ahead time as well.
