Studies indicating historical CO2 levels lag behind temperature have merit, confirms Peter Hildebrand, Director of Earth Science at NASA's Goddard Space Flight Center. Responding to a question on Twitter, Hildebrand explained that in the pre-industrial age, temperature changes drove CO2 levels; a warmer climate caused the biosphere to emit more CO2.

However, in the post-industrial era, this dynamic has reversed. Now, increasing atmospheric CO2 is leading to higher temperatures, indicating a fundamental shift in the physical-biological processes. For more information, visit Ask A Climate Scientist.

Talks at Google.

Peter Kohler, founder of The Plastic Tide project, and Dr. Stefan Leutenegger, Lecturer in Robotics at Imperial College London, discuss how the ocean is under siege from an ever-increasing tide of waste, and how technology like machine learning and drones can help us fix the issue.

Threatening not only a vital economic resource worth an estimated $5 trillion a year but also humanity’s very own life support. The Plastic Tide initiative was started almost two years ago, with the aim of quantifying the problem using drone imagery of UK beaches and beyond: raised awareness and precise data will hopefully drive solutions at societal, political, and technological levels.

They have collected a huge database of drone imagery around UK beaches last year, and a prototype algorithm developed already combines a deep-learning-based plastic detection scheme in the images with geo-referenced mapping. The speakers will show early results and present related research in the space of localization, mapping, and drone flight; and furthermore, sketch the way forward to limit the plastic tide swamping our oceans.

Princeton Bioethics professor Peter Singer, author of "Animal Liberation Now," challenges our factory food systems and the psychology behind them. He examines ethical dilemmas concerning animal welfare, environmental sustainability, and speciesism, advocating for a shift towards ethical eating.

Singer proposes plant-based diets and cultured meat as sustainable alternatives, emphasizing the importance of considering suffering. His influential work, which inspired effective altruism, encourages informed dietary choices for a more ethical and sustainable future.
