March 2023 IPCC (Intergovernmental Panel on Climate Change) Sixth Assessment report: Global warming is about 1.1 ° C, if current climate policies continue, the global warming is expected to be 3.2 ° C in 2100
In 2019, NASA released the "35-Year Change in Arctic Ice" video, which reduced the area by 96%! IPCC: Greenhouse gas emissions need to be reduced by at least 43% below 2019 levels by 2030 and by at least 60% by 2035. If governments act now, they can still ensure a livable and sustainable future for all, and the next decade will be decisive!
Michael Mann, a climate scientist at Pennsylvania State University, said: "Massive melting of glaciers, rising sea levels, coastal cities will be at risk of disappearing under water, 18% of biodiversity will be affected, and more than 99% of coral reefs will die." More and more severe extreme heat, dangerous hot and humid weather, extreme rainfall and associated floods, tropical cyclones and other hazards intensified.
To achieve the goal of "double carbon", not others let us do it, but we must do it ourselves. China has entered a new stage of development. To promote the work of "dual carbon" is an urgent need to solve the outstanding problems of resource and environmental constraints and achieve sustainable development, to comply with the trend of technological progress, to promote the transformation and upgrading of economic structure, to meet the people's growing needs for a beautiful ecological environment and to promote harmonious coexistence between man and nature. It is an urgent need to assume the responsibilities of a major country and promote the building of a community with a shared future for mankind.
According to the research results at home and abroad (International Energy Agency, IEA and other institutions), carbon neutral goal of the world/China emission reduction: negative carbon technology path will become the main way to reduce emissions!
DACS and BECCS have been identified by the IPCC Sixth Assessment Report as the CDR option with the highest storage persistence, while AR (Afforestation) is the option with the lowest storage persistence.
Traditional CCUS is difficult to capture 100%, and the essence is to increase emissions, which is different from the carbon properties of DAC. CO2 can provide a basis for "negative emissions" only when it comes from biological processes or directly from the atmosphere.
