Scientific Questions

Is there sufficient scientific evidence for 1.5℃ or 2℃?
Is atmospheric circulation environment, extreme weather, and climate response to the 1 or 2℃ of warming reversible? Is it predictable?

Where we focus

1. 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

2. TO REDISCOVER THE PRESENT CLIAMTE SYSTEM

  • To identify and diagnose irreversible processes in the past and future
  • To investigate interactions between tipping elements
  • To analyze the possibility of a catastrophic chain reaction

3. 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
  • Integrated research including geochemical processes

4. 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
