Did not know which title intro fits better: ‘Watch-Outs’ or
‘Technical Trends worth noting’ as I start this entry.
Last evening a local library sponsored a stimulating
discussion on weather changes influenced by arctic sea-ice
Her presentation offers a clear-minded assessment of
observations of Arctic sea-ice and land-ice losses. They
impact winds in at least three ways and ocean
levels in as many ways through combining impacts.
[you never know how these links display!]
where she is the third speaker.
She describes three effects of the loss of the Arctic sea-ice cap
- weaker steering winds
- wavier jet stream
- stagnant formations of wind flow (resulting from jet
On top of sea ice recession, land-ice loss due to thermal
effects due to less reflection of solar radiation (Less ice,
polar cap is darker and more absorbent) raises sea levels
and enhances storm water surges in coastal regions.
Her talk last night ended with forecasts for future
scenarios that point to the need for important changes
in global behaviors, changing populations settling and
migration patterns and serious infrastructure redesigns.
[Several of these are pointed out in the Wilson Center
