Scientific Questions

01

Is there sufficient scientific evidence for 1.5°C or 2°C?

02

Is atmospheric circulation, environment, extreme weather, and climate response to the 1 or 2°C of warming reversible? Is it predictable?

Where we focus

Why the gap?

and what is the real? 

  • Lack of physical understanding of tipping elements

  • Consider various tipping elements

  • Interaction through C/N cycle and dynamical/thermodynamical processes

  • Process bias correction (beyond mean bias)

  • Reversibility and its range analysis

  • Locality in irreversibility

To rediscover the present climate system

  • To identify and diagnose irreversible processes in the past and future

  • To investigate interactions between tipping elements

  • To analyse the possibility of a catastrophic chain reaction

Paradigm shift in the climate system

  • Major tipping elements;
     - Gas hydrate in permafrost
     - Dynamical/thermodynamical processes of the ice sheet and sea ice

  • Understanding of irreversible climate components
    and their interaction

  • A large uncertainty in circulations and feedbacks

  • Integrated research including geochemical processes

Nonlinear responses in East Asian extreme weather and climate

  • The response of East Asian extreme weather to global warming is NOT linear. 

  • A large possibility of amplified nonlinearity due to the simultaneous effects coming from the Arctic and tropical forcing, and mid-latitude internal dynamics

  • Evaluation of the response to linear/nonlinear climate change and its influence 

  • Evaluation of predictability and of the possibility of the nonlinearity amplification based on feedback processes in tipping elements
