Dr. Kobashi has been investigating how natural systems including ourselves operate, conducting researches in various fields (e.g., historical perspectives of nature using different kinds of tools and climate policy for Asia) . That should help us understand where we were in the past and where we are at present. With that knowledge, we would know our choices of where we go from here.

Protecting the Holocene climate
Human society was born about 11,500 years ago with the advent of agriculture and grown to the current complex society. The reason why our society could develop to the current state is because we were protected by the warm and relatively stable climate of the Holocene. Amid uncertainties of the future climate, one thing is sure. If we can protect the Holocene climate, we can be sustainable for the next 1,000 years and beyond. We have published arguably the most accurate Holocene temperature record in 2017. If you are interested, you can take a look and know how the Holocene climate looks like: https://www.nature.com/articles/s41598-017-01451-7
