Final answer:
The 2015 Paris Agreement on Climate Change aimed to limit global temperature increase to 2 degrees Celsius, with efforts for a more stringent target of 1.5 degrees Celsius.
Step-by-step explanation:
The 2015 Paris Agreement on Climate Change aimed to limit the increase of global temperatures to 2 degrees Celsius with efforts to keep the increase to 1.5 degrees Celsius. This landmark agreement was reached by 195 countries during the United Nations conference on climate change in Paris. To prevent catastrophic impacts on both human and natural systems, the agreement stresses the importance of deep cuts in greenhouse gas emissions and the promotion of renewable energy resources to control global warming. Unfortunately, as of the knowledge cutoff in 2023, not all countries have taken the necessary steps to meet these critical targets.
