Warmer temperatures, on land and at sea, are changing global weather patterns and changing how and where precipitation falls. These changing patterns aggravate dangerous and deadly droughts, heat waves, floods, wildfires and storms, including hurricanes. They also melt ice caps, glaciers and permafrost layers, which can lead to sea level rise and coastal erosion. Warmer temperatures also affect entire ecosystems and unbalance migration patterns and life cycles. For example, an early spring can make trees and plants bloom before bees and other pollinators appear. While in some regions global warming means longer growing seasons and increased food production, areas already facing water shortages are expected to become drier, creating the potential for drought, crop losses or forest fires. The 2010 Cancún Agreements contain voluntary commitments by 76 developed and developing countries to control their greenhouse gas emissions. [145] In 2010, these 76 countries were responsible for 85% of annual global emissions. [145] [146] “A safer, safer, more prosperous and freer world.” In December 2015, this is the world that President Barack Obama imagined when he announced that the United States, along with nearly 200 other countries, had committed to the Paris Climate Agreement, an ambitious global action plan to combat climate change.

The inventory is part of the Paris Agreement`s efforts to create an “increase” in emissions ambitions. In 2014, when analysts agreed that NDCs would not limit temperature rise to below 2 degrees Celsius, the global inventory brings parties together to assess the evolution of their new NCPDs so that they permanently reflect a country`s “highest possible ambitions.” [29] As shown in the graph above, other milestones have been reached since 1992 in the negotiations at events such as the CONFERENCE OF THE PARTIES. Below are the main agreements on climate change: scientists have been warning for years of the disastrous environmental consequences if global temperature continues to rise at the current rate. The average temperature of the planet has already increased by about 1°C compared to pre-industrial levels. In a 2018 special report, the IPCC predicted that the world would reach a warming of 1.5°C between 2030 and 2052, without a dramatic reduction in carbon emissions. The Paris Agreement is an ambitious, dynamic and universal agreement. It covers all countries and emissions and is designed to last. It is a monumental agreement. It consolidates international cooperation in the field of climate change. It offers a path forward. At the same time, another study published in 2018 finds that even with warming of 1.5°C in India, South Asia and Southeast, a significant increase in the incidence of high river flows can be expected. [97] However, the same study indicates that with a warming of 2°C, different areas of South America, Central Africa, Western Europe, and the Mississippi region would see more high currents in the United States; increases the risk of flooding.

Based solely on the current climate commitments of the Paris Agreement, temperatures are expected to have risen by 3.2°C by the end of the twenty-first century, according to the United Nations Environment Programme (UNEP). To limit the increase in global temperature to 1.5°C, annual emissions must be below 25 gigatonnes (Gt) by 2030. With the current november 2019 commitments, emissions will be 56 Gt of CO2e by 2030, twice as much as the environmental target. To limit the increase in global temperature to 1.5°C, the overall annual reduction in emissions of 7.6% per year is needed between 2020 and 2030. . .
