Climate change has a long history. For many centuries, the idea that human activity could influence the planet's weather patterns seemed to be far-fetched. Ancient Greeks even proposed that they could alter rainfall by plowing fields and cutting down trees. It took scientists until the 20th century to realize that humans could affect the climate.
Scientists began to collect data on the impact of greenhouse gases upon the climate in 1950s. One of the first recorded findings was the "Keeling Curve," a graph documenting the rise of CO2 levels over time. This was one evidence of the greenhouse effect, and it was one of the greatest scientific discoveries of the 20th-century.
After World War II was over, governments began to think about ways to slow down greenhouse gasses emissions. Increased global temperatures would cause more droughts and stronger hurricanes, scientists predicted. Many even predicted an imminent ice ages. However, scientists stopped warning of an imminent ice-age after the cooling period was over.
By the mid-1980s, temperatures had begun to rise. Droughts and wildfires were common in the United States as the 1988 summer reached its peak. A series of climatic phenomena confirmed that global warming was true.
During the early 1970s, scientists began recognizing the presence of aerosol particles that blocked sunlight. The Second Industrial Revolution introduced electricity, fertilizers and other pollutants to the atmosphere. They also accelerated land clearing, increasing greenhouse gas emission rates.
In 1987, the Montreal Protocol was created. This is another significant milestone in the history climate change. This protocol called for the total ban on chlorofluorocarbons, or CFCs. Based on research conducted by three scientists, it was based upon abnormally low levels of ozone over the South Pole in 1985.
In 1972, the United Nations Scientific Conference (UNSC) convened the first Earth Summit in Stockholm, Sweden. The conference released a declaration on the environment of humans and called for monitoring climatic change. It also created the Governing Council of the United Nations Environment Programme and the Environment Coordination Board. These bodies created programs for acid rain and a program to protect the ozone layer.
Politicians, journalists, and businesses were all interested in global warming. In popular magazines, it was described as a sign that an impending ice era is imminent. There were also warnings of droughts and severe heat waves. Although these warnings were not substantiated, they gained significant attention.
The United Nations Framework Convention on Climate Change (UNFCCC) was the first international treaty that addressed global warming. It was designed to reduce greenhouse gas emissions from industrialised countries. The Kyoto Protocol was signed on 1997 and became effective in 2006.
The Paris Agreement superseded the Kyoto Protocol in 2015 and set a goal of limiting global warming to 1.5 degrees Celsius. Countries must decrease carbon emissions to this level. Without this, the Earth may experience catastrophic consequences.
FAQ
What are the impacts of climate change on developing countries and communities?
Due to their limited access to healthcare and technology, developing countries and communities are especially vulnerable to the impacts of climate change. Changes in temperature, precipitation, and sea levels increase pressure on already scarce resources, with floods and droughts wearing away at already fragile ecosystems. Rising temperatures can cause a drop in crop yields which will adversely impact the poorer communities that are struggling to feed their families. Extreme weather events, such as hurricanes and heatwaves, can cause the destruction of infrastructures and displacement of people, which further perpetuates 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. While mitigating greenhouse gases is essential to build resilience to these risks, there are other options available. These include better management of freshwater resources and easier access for health facilities. This helps with the prevention of diseases such as malaria.
What is the role that individuals and groups can play in addressing climate-change?
Climate change is one our greatest contemporary challenges. This is a problem that affects everyone. We must all pay attention to it and take action individually to make a 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.
It is important that communities are involved in the larger climate change effort. They can implement policies that limit emissions by reformulating energy models based on renewable sources, promoting efficient infrastructure for cycling or electric transportation, reducing deforestation rates, or encouraging composting systems for waste management. Collaboration is crucial for the achievement of this mission.
Furthermore, it is important to start education in the early stages and continue learning throughout your life. This will enable individuals to become more aware of the issues and better understand how we are connected with other societies that are similarly affected by global warming.
Ultimately employers have a major responsibility when it comes to fighting climate change: introducing corporate practices focused on sustainability and opting for green alternatives whenever possible will undoubtedly yield positive results both economically and sociologically speaking.
Therefore individuals' actions plus community-wide policies together with business transformation will contribute immensely towards creating solutions against global warming and collectively defending humanity against longer terms harmful effects growing out from climate change.
Climate change: What is it and how can it happen?
Climate change is the long term shift in global weather patterns resulting from an increase of greenhouse gases. These gases trap heat which causes global temperatures to rise. This can cause a wide range of changes in weather conditions and climate. These can include rising sea level, melting glaciers or droughts, widespread coral bleaching, species extinction and disruptions in food production.
The main cause of climate change is human activity such as burning fossil fuels for electricity and transportation, cutting down forests, and farming livestock. These activities cause the atmosphere to heat up much faster than natural processes, like volcanic eruptions. They also emit many times more carbon dioxide than volcanoes.
Global greenhouse gas emissions are also influenced by deforestation, which contributes about 15-20%. Deforestation is when trees are cut down and burned. This releases carbon dioxide from the trees back into the atmosphere. 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.
The release of CO2 into the atmosphere is not the only effect of human-caused polluting. Other harmful gasses like methane, CH4, and nitrous dioxide (N2O), are also emitted by humans. Methane has been used extensively in industrial processes and contributes significantly to atmospheric warming while N2O is emitted primarily from agricultural soil management activities like fertilization or tilling which release excess levels of nitrogen into soil leading to N2O production upon microbial contact.
To minimize climate change humanity must make concerted efforts across social, economic, and political institutions to reduce these emissions drastically and transition away from our dependence on fossil fuels towards renewable energy sources such as solar, wind power, or low-carbon hydrogen fuels. The smart solution to reduce CO2 accumulation and atmospheric pollution could be replacing polluting fossil energy sources with zero-waste solutions. Our environmental impacts can be reduced by adopting preservation measures like reforestation. These projects help to preserve biodiversity and absorb large amounts CO2 from the environment. This helps in addressing climate change and restoring balance for future generation.

How To
How to Support Climate-Friendly Businesses and Policies
There are many ways that individuals can support climate-friendly companies and policies. 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 immediately take more practical steps such as switching providers when possible to ones that have a better environmental record or choosing sustainable products over those with higher carbon emissions.
Supporting climate-friendly policies and companies is one of the most important steps in reducing one’s carbon footprint. This could be done by changing everyday habits such as not plugging appliances or turning off lights, using public transportation, carpooling or using other means to get around, and using eco-friendly household items such as biodegradable cleaning materials and composting kitchen leftovers.
Investors who wish to support climate-friendly policies need to research companies with lower carbon emission before they invest. Investors who are interested in supporting climate friendly policies should research companies that emit less carbon than they own. They should also review their portfolios frequently to make sure they comply with the sustainability standards set by them. Green bond investors will want to ensure their investments do not fund any activity that releases more greenhouse gases into the atmosphere than it takes away. Investors should consider any opportunities that could allow funds to be used for green business activities. These include renewable energy alternatives as a way to promote sustainability and community-building projects using green technologies.
