Understanding Global Change:
Recognizing the critical link between data and supercomputing,
ORNL is a key player in gathering and providing the best possible data and analysis --
information needed to advance our understanding of global climate change.
ORNL operates several national data centers and data gathering experiments:
5lab report : "..a vigorous national commitment to develop and deploy cost-effective energy-efficient and low-carbon technologies could reverse the trend toward increasing carbon emissions...(with) energy savings ...roughly equal to or greater than costs."
1997 Presidential address to the UN: "The science is compelling and clear: we humans are changing the global climate. ... In order to reduce greenhouse gases and grow the economy, we must invest more in the technologies of the future."
ORNL researchers are collaborating with other government agencies
and universities to advance understanding of global climate change
by combining the best possible information with
advanced computing techniques in complex simulations.
ORNL's work in regional climate prediction combines data gathering,
analysis, and simulation techniques. Many climate effects can only
be properly assessed at regional scales or below. Just as fine scale data must
be aggregated for use in global models, global predictions must be downscaled
for use in regional predictions.
Global prediction and Regional data combine to generate Trends and Anomalies then researchers apply Statistical methods to get Regional predictions.
11lab report (from summary): "...the United States should develop and pursue a detailed and comprehensive climate change technology strategy. Further, the planning process should begin immediately, and implementation of the strategy should occur quickly."
