The Whole Earth – An Holistic Approach
• Seamless
• Multi-scale (spatial & temporal)
• Multi-science (physical & socio-economic)
The New Grand Challenge
We have been treating the sciences as
separate stovepipes and silos
for over 200 years!

The Father of Modern Meteorology
Before the Age of Computing
In 1922, Lewis Fry Richardson, a British mathematician
and meteorologist, proposed an immersive giant globe
to numerically forecast weather. This “factory” would
employ 64,000 human computers to sit in tiers around
the interior circumference of a giant globe.

Evolution of Forecasting Accuracy
Weather & Climate Communities
(A Convergence of Methodologies)
• Numerical Weather Prediction (NWP):
National Bureaus of Meteorology today: 3~5 days
ECMWF today: 5~10 days
Future Goal: increased accuracy, and on to monthly & seasonal level
• Climate modelling:
WCRP today: 100~1000 years
Future Goal : increased accuracy, and on to decadal & annual level
• The 10-year Challenge:
Seasonal to inter-annual predictions
Global to regional to local forecasting
Coarse-grain to fine-grain spatial resolution
Extreme weather early warning
