To avoid major changes in life as we know it, global action is needed. That is why the Paris Agreement, which aims to limit global warming, rises to 1.5 degrees Celsius this century. In fact, the seemingly small difference between 1.5 and 2 degrees could have dramatic consequences on deep nations and coral reefs. Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent radiation from the Earth`s surface to space, creating what is called the greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the main international panel on this issue, the concentration of these thermal gases has increased significantly since pre-industrial times and has not been observed for at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40 per cent, nitrous oxide by 20 per cent and methane by 150 per cent since 1750, mainly due to the burning of dirty fossil fuels. The IPCC says it is “extremely likely” that these emissions have been primarily responsible for the rise in global temperatures since the 1950s. Meanwhile, deforestation and forest degradation have also contributed to their fair share of global carbon emissions. Negotiators of the agreement stated that the INDCs presented at the time of the Paris conference were insufficient and found that “the estimates of aggregate greenhouse gas emissions in 2025 and 2030 resulting from the planned contributions at the national level are not covered by the least expensive scenarios of 2oC, but lead to a projected level of 55 gigatons in 2030.” and recognizes that “much greater efforts to reduce emissions will be required to keep the global average temperature increase to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.” [25] [Clarification needed] We have an agreement and we now have the chance to reach our goal. We cannot say that without an agreement.

The Paris Agreement will allow us to reach the target of 2 degrees Celsius or less. We did not expect to leave Paris with commitments to achieve this goal, but with a process that will lead us to it.
