The history of climate changes is not a short one. The notion that human activity could affect the planet's weather patterns was thought to be absurd for centuries. The ancient Greeks suggested that humans could alter the weather by plowing fields or cutting down trees. However, scientists did not accept that humans could actually alter the climate until the twentieth century.
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 graph provided evidence of greenhouse effect and was one of 20th century's most significant scientific discoveries.
After World War II was over, governments began to think about ways to slow down greenhouse gasses emissions. Scientists predicted that droughts and more powerful hurricanes would result from the increased global temperature. Some scientists even warned that there could be an ice age. But when the cooling period ended, scientists dropped their warnings.
Temperatures began to rise by the mid-1980s. Droughts and wildfires were common in the United States as the 1988 summer reached its peak. A series of climatic incidents confirmed that global warming theory is true.
During the early 1970s, scientists began recognizing the presence of aerosol particles that blocked sunlight. The Second Industrial Revolution introduced fertilizers and electricity to the atmosphere, which in turn led to increased air pollution. They also increased greenhouse gas emissions by speeding up the clearing of land.
The 1987 creation of the Montreal Protocol is another important milestone in the history and evolution of climate change. This protocol mandated the total ban of chlorofluorocarbons. It was based in part on research done by three scientists who found abnormally low levels ozone near the South Pole during 1985.
1972 saw the United Nations Scientific Conference (UNSC), convene the first Earth Summit. 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 developed acid rain programs and a program for the protection of the ozone layer.
Global warming was a subject of interest among politicians, businesses, and journalists. It was portrayed in popular magazines as a possible harbinger of an impending ice age. There were also predictions of severe heat waves and droughts. These warnings, although not supported by science, received significant attention.
The United Nations Framework Convention on Climate Change (UNFCCC) was the first international treaty that addressed global warming. It was established to reduce the global warming effects of industrialised nations. The Kyoto Protocol, which was signed in 1997, became effective on January 1, 2005.
The Paris Agreement superseded the Kyoto Protocol in 2015 and set a goal of limiting global warming to 1.5 degrees Celsius. These countries must reduce their carbon emissions. If this is not done, the Earth will be facing catastrophic consequences.
FAQ
What is the relationship between climate change and extreme weather events?
Global warming is directly responsible for extreme weather events such as heat waves and floods, droughts. Cyclones, storms and hurricanes are all a result of global warming. Global warming has contributed to an increase in the atmospheric temperature.
According to climate scientists in 1980, extreme weather-related natural disasters have increased by more than twice the rate. The sea level rises due to rising ocean temperatures and changing wind patterns. This can affect the distribution of hurricanes and storms in different geographic regions around the globe.
Warm water was pushed towards South America by the 2015 El Nino event. This caused rising temperatures to alarming levels. Heavy rains also caused flooding in Peru and Bolivia, causing displacement and property damage. 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 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 (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.
What causes climate change?
Climate change is a global phenomenon that has been driven by an increase in human-generated greenhouse gases emitted into our atmosphere, primarily due to fossil fuel burning for electricity and transportation. These greenhouse gases trap more heat from the sun, which causes global warming.
Other factors contributing to climate change include population growth, land clearing and destruction of ecosystems, deforestation, energy consumption, and over-grazing. This decreases the amount naturally occurring carbon sinks that absorb carbon dioxide from the atmosphere. Changes in solar radiation and other natural forces can also contribute to climate changes.
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 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.
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 essential to reduce our dependence on fossil fuels in order to produce electricity. This can be done alongside investing in renewable energy sources such as wind turbines and solar panels, which emit no harmful pollutants into the atmosphere. Reforestation and other sustainable practices can help restore balance to these delicate planetary cycles that we depend on for our survival.
What is the current status of the global climate, and how is it changing in the future?
The current global climate state is one of unprecedented change and uncertainty. 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 are already having a profound impact on ecosystems around the world, causing extinctions and disruption of habitats. These changes are also threatening billions of lives and livelihoods, especially those living in areas of resource scarcity or poverty.
Increased average surface temperatures, which are caused by human activity, have led to an increase of extreme weather events, such as hurricanes or cyclones. As temperatures rise, this trend will likely continue.
Climate change has global consequences. It can affect everything, from food insecurity and displacement to communities that are forced to relocate due to severe weather events or rising sea levels. Climate change is also contributing to existing social inequalities. Itdisproportionately affects marginalized communities, which lack the resources and knowledge required to adapt.
Although there have been some progress in efforts to reduce carbon emissions and renewable energy initiatives in certain countries, it is still not clear that meaningful global action is required to mitigate these changes. In order for us to prevent further disruption and devastation from climate change all nations must come together and take urgent action now while at the same time planning for adaptation in an increasingly uncertain world.
What is the state of international efforts for climate change mitigation?
The international effort to tackle climate change has reached a new level of unity and momentum. 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, 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, (UNFCCC), provides political guidance and pilots new initiatives like carbon market mechanisms.
In certain regions, there is progress as well. The European Green Deal, for instance, is a comprehensive set of legislation that aims to rebuild Europe's economy while African countries have committed to the African Renewable Energy Initiative. This Initiative aims to increase Africa’s global share of renewable energy production.
Action can also be seen across industries and sectors. Cities are moving towards sustainable public transport, while the whole society is adopting more sustainable lifestyles. Companies are developing technologies to reduce emissions, while investors shift their capital away fossil fuels in favor of renewables.
The wealthy countries represented under the OECD committee have adopted common standards for reporting national actions on climate change through the Common Reporting Framework (CFR) called 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.
