US President Barack Obama and Chinese President Xi Jinping, along with other world leaders, emphasized the need for an agreement to address the rising global temperatures that are causing extreme weather events and rising sea levels. However, as the leaders departed from Paris, negotiators from 195 countries were left to work on a draft text of over 50 pages that still contained numerous disagreements. The main challenge is determining how to secure the necessary funding to support cleaner energy sources, which are essential for the development of emerging countries without relying heavily on fossil fuels. Despite these obstacles, many delegates expressed optimism due to the high number of attendees at the UN climate summit in Paris, following the failure of the 2009 Copenhagen summit. French President Francois Hollande expressed encouragement for the ongoing talks scheduled to continue until December. 11. He informed the reporters that while the journey started successfully, it still needs to reach its destination. He explained that there are two obstacles to overcome: either the vessel will sink from being overloaded, or it will remain stationary if emptied. The technical discussions did not contain the same grandiose language as Monday's statements. Countries reiterated their negotiating positions without showing much willingness to compromise. China's representative Su Wei expressed concern over the lack of commitment from wealthy nations to reduce greenhouse gas emissions and provide financial assistance to developing countries to combat global warming. Alden Meyer from the Union of Concerned Scientists described the discussions as getting down to the essential details, noting that while the opening day was positive, crucial issues still needed to be resolved. Peruvian Environment Minister Manuel Pulgar Vidal stated that there were numerous options in the text, but all parties had demonstrated their dedication to reaching an agreement. The atmosphere was lifted by significant announcements, such as India and France's plan to raise $1 trillion for solar power in impoverished regions and a private sector initiative led by Bill Gates to generate billions of dollars for new energy research and development. Yvo de Boer, a former UN climate chief, mentioned that leaders are still affected by the Copenhagen conference. He noted that the strong presence of leaders at the opening day of the Paris conference shows their determination to take action. A potential deal in Paris would be the most powerful agreement to date in terms of binding both wealthy and developing nations to reduce greenhouse gas emissions. Liz Gallagher from the E3G environmental think-tank believes that the opening day has increased the likelihood of reaching an agreement, but highlighted that the main challenge lies in climate finance. Developing nations are calling on wealthy countries to increase their financial contributions beyond the current target of $100 billion a year by 2020 to support clean energy initiatives and prepare for the impacts of climate change. Disagreements also exist over setting a long-term goal for reducing fossil fuel use. The G7 nations committed to decarbonising the world economy by 2100, but countries like China and India argue they need to continue using coal to address poverty concerns. Despite pledges from around 170 countries to reduce greenhouse gas emissions post-2020, these commitments are not strong enough to prevent global temperatures from increasing beyond 2 degrees Celsius. This is commonly seen as a point where significant and possibly disastrous alterations occur in the Earth's climate system.
