【摘要Abstract】
Throughout human history, multiple industrial and agricultural revolutions that have profoundly transformed the world. However, the unintended consequence of these revolutions is that the greenhouse gas emissions are changing Earth’s climate. Most of our energy sources and many of the materials we use are based on fossil-fuel. The challenges how to provide clean energy, water, air and food in a world of over 8 billion people and likely to grow to 11 billion by 2100 are formidable. After a brief summary of our current trajectory, I will discuss the current progress, opportunities and challenges needed to achieve net-zero greenhouse emissions that will include food production and capture CO2.
在人類歷史中，多次工農業革命深刻改變了世界。但始料未及的是，這些變革帶來的溫室氣體排放正改變地球氣候。目前，我們的能源和材料大多依賴化石燃料。全球人口已超 80 億，2100 年可能增至 110 億，如何在這樣的世界中保障清潔能源、水、空氣和食物供應，是艱巨挑戰。我將先簡述當前發展軌跡，再探討實現溫室氣體凈零排放（含糧食生產與二氧化碳捕集）的進展、機遇與挑戰。
【報告人簡介About the Speaker】
Prof. Steven Chu is the William R. Kenan, Jr. Professor at Stanford University. He was awarded the 1997 Nobel Prize in Physics for his groundbreaking work on laser cooling and optical trapping of atoms, a foundation of modern atomic physics.
From 2004 to 2009, Prof. Chu directed the Lawrence Berkeley National Laboratory. From 2009 to 2013, he served as U.S. Secretary of Energy under President Barack Obama, where he led major clean energy initiatives such as ARPA-E and Energy Innovation Hubs. Prof. Chu has made contributions across physics, biophysics, and engineering, including atomic fountain clocks, optical tweezers, and single-molecule FRET techniques. His current research spans biophysics, medical imaging, nanoparticle synthesis, and battery technology.
Prof. Chu is a member of multiple national academies, including the U.S. National Academy of Sciences and the Chinese Academy of Sciences, and has received over 35 honorary degrees worldwide.
朱棣文教授是美國斯坦福大學威廉·R·肯南Jr.講席教授。他因開創性地提出激光冷卻與光學捕獲技術，于1997年榮獲諾貝爾物理學獎，為現代原子物理奠定了基礎。
2004 年至 2009 年朱棣文教授擔任勞倫斯伯克利國家實驗室主任。2009年至2013年，他出任美國能源部部長，期間推動了ARPA-E、能源創新中心（Energy Innovation Hubs）等重要清潔能源計劃。他的研究橫跨物理、生物物理與工程學，涉及原子噴泉鐘、光鑷技術、單分子FRET成像等領域。目前研究方向包括生物物理學、醫學成像、納米顆粒合成與電池儲能等。
朱棣文教授是美國國家科學院、中國科學院等多國頂尖學術機構的院士，曾獲全球三十余所高校授予的榮譽博士學位，享有極高國際聲譽。
