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