Abstract:
Climate change is the greatest challenge humanity faces in the 21st century. We can’t count on just fancy technologies to solve this problem, but rather need a portfolio of solutions. Based on 15 year of research, here I discuss two low-tech technologies that offer exciting new opportunities: 1) low-cost high-density IoT sensors to monitor greenhouse gas emissions and air pollution; 2) Burying woody biomass to remove CO2 from the atmosphere. These ‘low-tech’ technologies are practical and effective, with great potential to contribute to climate mitigation.
