Coping with climate change is crucial for the common future of humanity. Only by doing our best and working together can we achieve harmonious coexistence between humans and nature, and protect our only home on Earth. The 30th Conference of the Parties (COP30) to the United Nations Framework Convention on Climate Change, currently being held in Belen, Brazil, carries the common expectation of all parties to embark on a decade of accelerated development and implementation of action. As an important prelude to the conference, the Belen Climate Summit reached the Belen Declaration, calling for more just and inclusive climate action, demonstrating the determination of all parties to unite and address the climate crisis. At present, global climate governance has entered a critical stage, and the international community urgently needs to unite and take concrete actions to send a clear signal that the global green and low-carbon transformation is irreversible. （1） Belen is the gateway city to the "lungs of the earth" Amazon rainforest. The holding of the Conference of the Parties to the United Nations Framework Convention on Climate Change here has special significance - it reminds us to revisit the original intention of all parties to reach the Paris Agreement 10 years ago. In December 2015, at the Paris Climate Change Conference, nearly 200 contracting parties reached the Paris Agreement, establishing an international mechanism for addressing climate change after 2020 with "nationally determined contributions" as the main body, reaffirming the principle of common but differentiated responsibilities established by the United Nations Framework Convention on Climate Change, and becoming an important milestone in global climate governance. Over the past 10 years, global climate cooperation has progressed through twists and turns, from completing negotiations on implementation details to establishing a "loss and damage fund," to 198 countries agreeing to "transition away from fossil fuels," and for the first time clarifying the direction of energy transition. Former French Prime Minister and COP21 President Laurent Fabius stated that thanks to the Paris Agreement, the expected global temperature rise has been significantly reduced. This positive trend reflects the importance of the international community taking concerted action. However, there is still a huge gap between ambition and reality. Frequent extreme weather, increasingly disrupted global water cycle, and rising greenhouse gas emissions... Recent research reports warn that the climate crisis has not eased and the global window for emissions reduction is rapidly closing. Geopolitical conflicts, weak economic recovery, and political interference in scientific issues have led to a slowdown in the momentum of global climate cooperation. Some developed countries' climate policies are wavering and weakening, adding more uncertainty to global climate governance. COP30 President Dorago pointed out that countries in the global North have lost their enthusiasm for addressing the climate crisis, while countries in the global South are continuing to move forward. （2） The era of negotiations has come to an end. Now is the time to implement, implement, and implement again. ”UN Secretary General Guterres' call in Bel é m warns the international community to push forward the global climate governance process with stronger ambition and practical actions. ——To address climate change, we must adhere to the principle of common but differentiated responsibilities. Data shows that nearly 80% of the world's poor live in areas that are vulnerable to climate disasters, while climate fragile countries such as small island nations face survival threats. Developed countries have a historical responsibility, legal obligation, and moral obligation towards climate issues, and should implement the obligation to take the lead in emissions reduction and financing, and provide more funding and technological support to developing countries. The voices at the Belem Climate Summit, such as' full respect for the development rights of developing countries', 'narrowing rather than widening the North South gap through global green transformation', and 'richer countries need to take more rapid and effective actions', reflect the international community's common expectation for achieving substantive fairness and ensuring climate justice. ——Coping with climate change and transitioning to green and low-carbon is the trend of the times. The reality of the deep connection between climate crisis and poverty determines that we must focus on the common and long-term well-being of people in all countries, work together to improve people's livelihoods and climate governance, and coordinate multiple goals such as protecting the environment, developing the economy, creating employment, and eliminating poverty. Currently, there is a huge demand for global green development, which requires an open and cooperative international environment. Countries should strengthen international cooperation in green technologies and industries, further enhance the accessibility and affordability of clean energy technologies through innovative cooperation, and strive to fill the gap in green production capacity; Break down trade barriers, ensure the free flow of high-quality green products globally, and enable green development to benefit every corner of the world. The United Nations Framework Convention on Climate Change and its Paris Agreement are the basic legal principles for international climate cooperation. All parties should uphold the spirit of the rule of law, honor their commitments, and jointly promote low-carbon development. ——The key to addressing climate change is to take concrete actions. The new round of nationally determined contributions is the focus of the Belen Conference. Currently, over 100 countries among the signatories of the Paris Agreement have submitted new national climate action plans and commitments. The 2035 national independent contribution target submitted by China has historically expanded to the entire economy, including all greenhouse gases; Brazil has committed to reducing net greenhouse gas emissions by 59% to 67% from 2005 levels by 2035 and achieving zero illegal deforestation by 2030; The European Union and its member states have proposed to achieve a 66.25% to 72.5% reduction in emissions by 2035, based on 1990 levels, and will raise 300 billion euros in funding to support the global transition to clean energy; Climate fragile countries such as small island nations have also actively proposed new national independent contribution plans. Starting from the goal of independent contribution, countries will further increase their ambition and accelerate their pace, which will better protect their people from increasingly severe climate disasters and reap huge economic and social benefits through stronger climate action. ——South South cooperation is playing a leading role in addressing climate change. The countries in the global South are accelerating the exploration of independent and diverse energy transformation models and climate financing solutions. China has achieved significant results in implementing its national independent contributions by 2030, and has completed the goals of total installed capacity of wind and solar power and forest storage ahead of schedule; India announced that it has achieved 50% of its installed electricity capacity from non fossil fuels five years ahead of schedule; 34 countries with tropical forests have jointly launched the 'Forever Tropical Rainforest Fund', covering nearly 90% of tropical forests in developing countries. Brazilian President Lula stated that promoting cooperation in the development of renewable energy in impoverished areas of Latin America and Africa can not only address the climate change crisis, but also create employment opportunities and economic benefits. Coping with climate change is crucial for the common future of humanity. Whether in the north or south, developing or developed countries, everyone is in the same boat, and only by working together is the only correct choice. （3） From Paris to Belen, China has always been a staunch advocate and important contributor to global green development. The latest white paper "China's Action to Achieve Carbon Peak and Carbon Neutrality" shows that since the announcement of the carbon peak and carbon neutrality target five years ago, China has built the world's most systematic and complete carbon reduction policy system, established the world's largest and fastest developing renewable energy system, formed the world's largest and most complete new energy industry chain, contributed about 1/4 of the world's new green area, and become one of the countries with the fastest decline in global energy intensity... Adhering to the "Two Mountains" concept, China has embarked on a modern new path of harmonious coexistence between man and nature, providing fresh samples for the world to solve the dilemma of "development and protection". Simon Steele, Executive Secretary of the Secretariat of the United Nations Framework Convention on Climate Change, pointed out that "China has a long and outstanding record in achieving and exceeding the objectives of addressing climate change and clean energy." China firmly upholds multilateralism, actively participates in global climate governance, works with co building countries to build the "the Belt and Road" into a green road, and signed 55 South South cooperation memorandums of understanding on climate change with 43 developing countries, providing support to the countries of the South within its capacity. The Alshubah Photovoltaic Power Station, constructed by Chinese enterprises, delivers clean electricity to thousands of households in Saudi Arabia; Chinese made solar panels light up rural areas in Zimbabwe; The Chinese "100% electric" buses that run on the streets of many Latin American countries are leading the global clean transportation revolution... The Economist, a British magazine, commented that the renewable energy revolution originating from China is having a profound impact on developing countries, and "cheap and abundant clean energy is expected to improve the lives of billions of people in developing countries". As pointed out by the attendees at the opening ceremony of the Bel é m Conference, Bel é m is the mouth of the Amazon River formed by a large number of tributaries, and the achievements of the Bel é m Conference must also rely on the convergence of various rivers in the international community. Only by doing our best and working together can we achieve harmonious coexistence between humans and nature, and protect our only home on Earth. (New Society)
