The history of climate change is long. For many centuries, the idea that human activity could influence the planet's weather patterns seemed to be far-fetched. Ancient Greeks even suggested that humans could alter rain patterns by plowing the fields and cutting down trees. However, it took until the 20th century for most scientists to accept that humans could indeed affect the climate.
In the 1950s, scientists started to collect data on the effects of greenhouse gases on the climate. One of the earliest recorded discoveries was the "Keeling Curve", which shows the evolution of CO2 levels over time. This was one the most important scientific discoveries made in the 20th century and proved the greenhouse effect.
After World War II ended, governments started to talk about how to reduce greenhouse gas emissions. Increased global temperatures would cause more droughts and stronger hurricanes, scientists predicted. Some warned of the imminent ice age. However, scientists stopped warning of an imminent ice-age after the cooling period was over.
The temperatures began to rise in the mid-1980s. As 1988 was reaching its hottest, droughts and wildfires ravaged the United States. A series of climatic events reaffirmed that the global warming theory was real.
In the 1970s scientists started to notice the presence aerosol particles that block sunlight. The Second Industrial Revolution also introduced electricity and fertilizers to the atmosphere. They also accelerated land clearing, increasing greenhouse gas emission rates.
The 1987 creation of the Montreal Protocol is another important milestone in the history and evolution of climate change. The protocol demanded the complete ban of chlorofluorocarbons or CFCs. The protocol was based a research project by three scientists that found extremely low levels of ozone in the South Pole between 1985 and 1995.
1972 was the year of the United Nations Scientific Conference, which convened the very first Earth Summit. It took place in Stockholm, Sweden. The conference issued a declaration on the human environment and called for monitoring of climatic changes. The conference also established the Governing Board of the United Nations Environment Programme (UNEP) and the Environment Coordination Board. These bodies developed programs against acid rain and a protection program for the ozone.
Journalists, businessmen, and politicians all had an interest in global warming. It was portrayed in popular magazines as a possible harbinger of an impending ice age. There were also warnings of droughts and severe heat waves. These warnings, although not supported by science, received significant attention.
The United Nations Framework Convention on Climate Change was the first international treaty to address global warming. It was designed to decrease the emissions of greenhouse gases from industrialised countries. The Kyoto Protocol was signed in 1997 and became effective in 2005.
The Paris Agreement replaced the Kyoto Protocol's 2015 version and established a goal for limiting global warming below 1.5 degrees Celsius. To achieve this goal, countries must reduce carbon emissions. If this were not done, the Earth could be experiencing catastrophic consequences.
FAQ
What does climate change politics have to do with global efforts to combat it?
Climate change is a hotly debated issue, which has led to a lot division among countries, governments, as well as individuals. The implementation of measures to address climate change is affected by the political stances of various actors. It is becoming difficult to reach consensus on global efforts for addressing this urgent environmental crisis.
The overwhelming majority of scientists agree with the fact that human-generated global warming is real. It is urgent for action to address it. 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 around the globe want to protect business interests and enforce policies that restrict business activities. This often clashes with regulations that experts recommend for effectively addressing climate change. Without strong commitments by all countries involved and large-scale international action it is difficult for any state or group to adequately address climate changes through legislation.
The difficulty of reaching a full consensus about the best way to combat climate change is further complicated by differences in power dynamics. 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. 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.
It is essential to distribute resources properly to any intervention program, and to be mindful of political divisions within nations, if we want to see an effective coordinated effort to mitigate our current environmental crisis.
What are the international efforts currently being made to address climate change
International efforts to combat climate change are moving at a remarkable pace and with unprecedented unity. International efforts to address climate change are being facilitated by countries around the world, who are increasingly working together to reduce carbon emissions, improve resilience and invest in renewable energies.
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. Additionally, the UN Framework Convention on Climate Change (UNFCCC) is providing political guidance and piloting new initiatives such as carbon market mechanisms.
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's wealthy members have adopted common standards in reporting on national actions related to climate change. These are the Common Reporting Frameworks (CFR), also known as the 2021 Guidelines.
These efforts all signify an unprecedented importance placed on 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.
What is the impact of climate change on biodiversity and ecosystems?
Climate change can have many impacts on biodiversity and ecosystems. Today's issues that impact wildlife and ecosystems include rising temperatures, increased sea levels and extreme weather events.
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 changes can lead to higher temperatures and more frequent extremes (such as droughts) which put more stress on already fragile systems, like coral reefs or tropical forests. The climate change will lead to the extermination or decline of as many as 30% of animal species in 2050. This could cause further destruction of ecological communities.
Climate change is a serious threat to biodiversity as well as human societies that rely on functioning ecosystems for food and fresh water. To mitigate its effect efforts must be made at all levels to reduce global warming trends and future damages should be avoided where possible with careful management practices.
What is the relationship between climate change and extreme weather events?
Global warming directly links extreme weather events like heat waves, floods. droughts. cyclones. storms. Atmospheric temperatures have increased due to global warming which has affected different weather phenomena on a global scale.
According to climate scientists the average frequency for extreme weather-related events has increased more than twofold since 1980. Sea levels rise as a result of changing wind patterns and ocean temperatures. This affects the normal distribution of storms and hurricanes in different geographical regions across the planet.
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 locations, including Antarctica recorded their highest ever temperatures. This shows that there is a clear relationship between global warming trends with the occurrence or frequency extreme weather events.
Another example is Hurricane Irma, which struck in 2017, causing $50 billion in economic damage not only to Florida, but also to other states like Puerto Rico, Cuba, and others. This proves once again that climate change has been responsible for an increase in major storms.
The Intergovernmental Panel on Climate Change's (IPCC) concluded, "Human activities are increasing the severity current climate change." This naturally leads worldwide to more severe, intense, and frequent natural disasters. There is strong evidence of humans' involvement with extreme weather events occurring frequently around us all.
