In the case of a deadly Japanese heat wave in 2019, modelers found that this simply would not have been done without human influence on the climate. It is rare that there is a consensus among almost all nations on a single subject. But with the Paris Agreement, world leaders agreed that climate change was fueled by human behavior, that it posed a threat to the environment and humanity as a whole, and that global action was needed to stop it. In addition, a clear framework has been put in place for all countries to make emission reduction commitments and strengthen these measures over time. Here are some important reasons why the agreement is so important: Christiana Figueres, who led the UN climate negotiations to seal the Paris Agreement (Photo: IISD) In order to combat climate change and its negative effects, 197 countries adopted the Paris Agreement at COP21 held in Paris on December 12, 2015. The agreement, which entered into force less than a year later, aims to significantly reduce global greenhouse gas emissions and limit the increase in global temperature to 2 degrees Celsius this century, while ways are being pursued to further limit the increase to 1.5 degrees. Based on the construction scenario for future temperature estimation, it is possible to keep the temperature increase below 2°C according to the IPCC climate model. The only evidence of the absence of positive water recoupling will reduce the temperature increase to 1°C under the bau scenario. Many of these companies are leaders in their industries and set a new standard for what climate protection should be in business. Microsoft, one of the world`s largest companies, will reduce its carbon footprint and invest in carbon capture solutions to become carbon negative by 2030. In 2019, Greta Thunberg and other young climate activists exploded onto the world stage with their weekly school strikes, known as „Fridays for Future,“ protesting the lack of climate action by world leaders. Supported by other youth activist groups, including the Sunrise Movement and the Extinction Rebellion, more than 7 million people in 185 countries joined the largest climate strike in global history in September 2019 to demand stronger government action. And at protests for racial justice in the United States and around the world in 2020, attendees often spoke about the disproportionate threats that climate change and other threats to the environment pose to communities of color and other vulnerable groups.
In fact, research clearly shows that the cost of climate inaction far outweighs the cost of reducing carbon pollution. A recent study suggests that if the U.S. fails to meet its Paris climate goals, it could cost the economy up to $6 trillion in the coming decades.
