In a fortuitous change—well, almost 200 countries have joined the fight for the environment—on the climate objective, which has been described as unrealistic, strengthening the response to the threat of climate change , sustainable development and efforts to eradicate poverty has become part of a universal agreement to move towards resilient societies and economies, according to The Conversation . But as is the case with most successes, the 1.5C vs climate change goal will be the result of intense preliminary work that requires coordinated solutions and international collaboration. But when or where was that purpose set? Who said that the planet's temperature must be limited? In the 1970s—when scientific understanding of climate change was still taking shape—American economist William Nordhaus stated that warming of more than 2°C “would push global conditions beyond any point ever experienced by any human civilization.” ”. Similarly, in 1990, scientists had also estimated that 2°C above the pre-industrial average was the point at which the risk of widespread and unpredictable damage would increase rapidly.
To establish a consensus, two years later the United Nations Framework Convention on Climate Change (UNFCCC) was established , which sought to stabilize the amount of Greenhouse Gases (GHG) in the atmosphere at a level that “ “will avoid dangerous interference with the climate system.” Maintain the 1.5C goal vs climate change At the first Conference of the Parties (COP), held in Saudi Arabia Email List Berlin in 1995, countries began negotiations for the global response to climate change that continue to this day. Since then, stopping global warming at 2°C remained the horizon negotiators fought for for almost two decades. However, you are more likely to hear that you need to get the temperature limit to 1.5°C. Even at the recent COP27 in Egypt, leaders reached an agreement to keep the target at 1.5°C, although they did little to help the world achieve it. So why did 1.5°C become the acceptable target for temperature rise? That story reveals an essential truth about climate change itself.
Where did the come from? Although there is no safe amount of global warming, a target of no more than 2°C global temperature rise has often represented the threshold for "dangerous climate change." The increase in global temperature is just one measure of how the climate is changing. Scientists also track CO2 concentrations in the atmosphere, sea level rise, and the intensity of heat waves and floods. But taking the Earth's temperature is the simplest way to predict the consequences of warming. At the 2009 climate summit in Copenhagen, Denmark, the world still lacked an official temperature target, nor was there a full scientific assessment of what was “safe.” But an organization of island nations known as the Alliance of Small Island States (AOSIS) was already calling for the 1.5°C limit. AOSIS urges action against climate change AOSIS commissioned scientists from the Potsdam Institute to learn about the impacts of a 2°C increase. They analyzed what this modification would look like, prompting countries such as Tuvalu, in Oceania, to declare that “it was clear that an increase in global temperature above 2 degrees would be disastrous.
