Hello everyone, today I will lead you to experience the beauty of nature with this familiar blue planet behind me - the Earth's climate change!
Different places on earth have different styles of weather at different times of the year. The Earth's climate has always been changing from ancient times to the present
But the warming in recent decades or centuries is unprecedented in the past millions of years and longer. It has also led to a high incidence of natural disasters.
The warming of the Earth due to human activities is becoming increasingly evident, with the Earth warming by about 1°C in the 50-year period from 1850 to 1900 to the present, and especially the warming rate in the last 50 years exceeds the 50-year warming rate of any period of the Earth in the last 2,000 years
Occurs in every region of the globe
In order to achieve the temperature control goal of the Paris Agreement, more than 100 countries around the world have declared their intention to achieve carbon neutrality.
Carbon neutral BECCS in CCUS is key to the overall plan, and in the IEA Sustainability Scenario, carbon capture in CCUS Phase III (2050-2070) increases by 85% over the previous phase, 45% of which comes from BECCS
As a core "member" of BECCS, microalgae play an extremely important role in the program. Through their powerful photosynthesis, microalgae fix about 1/5 of the world's CO2, equivalent to the contribution of an entire tropical rainforest.
Behind this powerful carbon sequestration capacity of microalgae is the silent efforts of chloroplasts
In our project, we use ascorbic acid to protect chloroplasts from oxidative damage, thereby enhancing the photosynthetic carbon sequestration capacity of microalgae
The engineered algal strain we constructed has stronger photosynthetic efficiency and higher lipid content
We have also discovered a convenient, low-cost method to increase microalgal biomass and fucoxanthin content, which has made our sponsors very interested in our results
In addition, we used modeling analysis to derive recommendations for the best sites in China for plants that fit our project's microalgae culture model.
This is our engineered algae strain, which is characterized by high photosynthetic efficiency, high oil production, and high fucoxanthin content
We hope that the implementation of our project will contribute to the goal of global cooling and carbon neutrality
