Climate and people -A conceptual framework for a sustainable future Takuro Kobashi Scripps Institution of Oceanography
Sustainability You have to return as much as you get!
Issues surrounding climate changes • Increasing greenhouse gasses by burning fossil fuel warm atmosphere = Need to reduce emission • Large part of human society still needs to use much more energy • Fossil fuel is a major driver of current human society • Sustainable society asks us for a major change How?
World still suffers in inequality • Recent rises of China and India (1/3 of human population) significantly improved the situation • However, still many people in the world live without the basic needs • Future climate changes likely impact those with less capacity or less energy intense life (positively, negatively) • Sustainability will impact all of us, but likely more people with intense energy use
Energy distribution in the world Basic needs Quality of life Now Future Geographical variation
World energy use in time Energy intensive Sustainability threshold Present Time
Key to future sustainability • The changes in world value system needs to happen • China and India may hold the key for the change with their sheer size • From like-USA (energy intensive life) to like-China or India (less energy intensive life) or like-somewhere else
Key for the sustainable future • The key for sustainability lives in nature and in our mind • The sense of equity need to be extended beyond human society • Other parts of natural system are as important as human society • Sustainable human society = sustainable natural system
Our perception of nature and human society Human society Human society Nature Nature Reality and sustainable future Current distorted view
Conclusion • Climate change issues are intricately related with sustainability issues • First, we need to accomplish equality in human society • Second, we need to extend the sense of equality toward nature • I believe that human society will make this change
