The U.N. Paris Climate Change Conference entails world leaders to agree on a global deal involving cutting carbon emissions beyond 2020 and also, to finance developing countries and poor nations to cope with the effects of climate change.

Beginning November 30 up until December 11, a total of 195 nations from around the world will be attending and at least 138 world leaders including U.S. President Barack Obama, China's Xi Jinping and India's Prime Minister Narendra Modi will be there, as only heads of states will be present during the start of the summit. The summit will be held at the north eastern suburb of Paris, in Le Bourget.

Now, the question is, will this climate change summit make a difference for everybody? The answer is yes but the effects are not immediate. Governments and international businesses'  long term decisions will be part of this Paris deal however, it will take years to be implemented upon. This can significantly affect power plants that provide energy to food sources and how floods can strike your home and even extreme weather conditions that are bound to happen in the future. 

There is already an existing climate deal known as the Kyoto Protocol which is also the world's only international climate treaty that legally binds developed nations and also EU, Australia and others that are required to cut emissions by 2020. There is also an existing separate binding declaration that covers voluntary cuts by rich and poor countries up to 2020.

To date, the specific challenge for nations to agree on a deal is how to finance poorer countries, according to France's top climate ambassador, Laurence Tubiana. Also, the United States and EU have different views on how legally binding this new agreement will be.

China and the Unites States are the two largest carbon emitters in the world and they have both expressed their support to the Paris deal, which is also a crucial difference from the last major climate summit in 2009, where China wrecked the Copenhagen talks. The third largest emitter is India and this might prove tricky, as the nation recently made it clear in the G20 that they are concerned with emission pledge reviews in the future. 

The good news is, more than 170 countries have already submitted their climate pledges to U.N., representing 97 percent of the planet's emissions. However, recent studies still state that those pledges will still see global temperatures increase by 2.7 to 3.3 degrees Celsius which is more than the 2 degrees Celsius threshold that world leaders have promised. Many nations now want to see this review mechanism in action, to monitor emissions for every nations, every five years. 

The estimated carbon footprint of the climate conference alone is estimated to be 21,000 tons of carbon dioxide, which is the total annual emissions of Estonia.
