When Was Global Warming Proven

The discussion surrounding global warming has stirred debate and controversy among policy makers, researchers, and citizens worldwide. While much of the focus has been on its potential effects and the need to take action to reduce emissions, the more fundamental question remains – when was global warming proven?
The debate over global warming dates back to at least 1896, when Swedish scientist Svante Arrhenius first proposed that burning fossil fuels could lead to increases in the Earth’s average temperature. He based his hypothesis on the observation that carbon dioxide, a greenhouse gas, could trap heat in the atmosphere. This early work laid the foundation for the modern theories of climate change, which argue that human activities, such as burning fossil fuels, have caused the Earth to become increasingly warmer since the Industrial Revolution.
Since Arrhenius’ time, much research has been conducted to assess the accuracy of his hypothesis. In the 1950s, scientists began to measure levels of carbon dioxide in the atmosphere and observe their effects on the Earth’s temperature. In the 1970s, meteorologists and oceanographers began to recognize that climate cycles could cause the Earth’s temperature to fluctuate over the course of years and decades, intensifying their efforts to detect a human influence.
In the late 1980s and early 1990s, advances in computer modeling allowed scientists to incorporate complexities such as earth-sun interactions, ocean circulation, and other climatic processes into the equations. As a result, climate models became more accurate and reliable for predicting long-term changes in the atmosphere’s temperature.
In 1995, the Intergovernmental Panel on Climate Change (IPCC) was formed, a collaborative body of literature specialists, climatologists, economists and policy makers tasked with assessing the scientific evidence of global warming and providing policy recommendations. In 2001, however, the IPCC issued its first report, stating with “great confidence” that human activities were causing global warming and the Earth’s temperature was going to continue to rise. This was an unprecedented statement, and though not accepted by all, it was the closest scientists had ever come to proving the existence of global warming.
Since then, the evidence of global warming has become even clearer, with multiple reports and studies showing conclusive evidence of the human contribution to climate change. In fact, the United Nations estimates that human activities have caused the Earth’s average temperature to rise by 1.5 degrees since the Industrial Revolution. Even in the face of rapid changes and extreme weather events, numerous international organizations have issued calls for action to tackle global warming.
In conclusion, global warming has been scientifically proven since 1995, when the IPCC first reported their findings on the effects of human activities on global climate. While some may still dispute this fact, the evidence is irrefutable, and
increasingly alarming. Therefore, it is essential to take swift and decisive action to mitigate the effects of global warming, so that the planet can be preserved for future generations to come.
