Two-Way Connections Between the Arctic and the rest of the Globe // Mar 26, 2019
Third video. I discuss a new UN Environmental Report titled “Global Linkages: A Graphic Look at the Changing Arctic” (Google it!). Mainstream Media focused on only one small part of the report (namely the question as to whether 3-5C of warming is locked-in for the Arctic) and ignored the rest of the report.
The report contains many excellent graphics that I chat about, namely the:
- Cryosphere, permafrost,
- Short-lived climate pollutants, persistent organic pollutants,
- Ocean acidification, plastics, mercury, and
- Biodiversity, including migration and invasive species.

Linkages from Globe to Arctic and from Arctic to Globe /// Mar 24, 2019
Second Video. ‘Most of the territory sweltered in record or near-record temperatures, triggering concern over rapidly disintegrating ice roads, a call in some quarters for government action on climate change, and even a warning about rotting meat‘.
Refs: ‘For first time since records began, NWT hits 20C in March‘. 20 Mar, 2019,
The Northwest Territories highway system: ‘Highways and Winter Roads‘.
Record Temperatures 20-25C Above Norm in far North /// Mar 23, 2019
First Video. The Northwest Territories of Canada had March temperatures above 20C for the first time (hit 21.6C or 71F); breaking norms by 20-25C (normal is below freezing). I discuss a new study from UN Environment that made global news about the inevitability of sharp rises in temperature being locked in.
Arctic temperature amplification has mostly been due to:
- Albedo declines with reduced sea-ice and land snow cover.
- Wavy jet streams bring heat (sensible and latent) to the Arctic;
- Arctic air moved south in a big blob over North America, and
- Ocean mixing brings heat from depth to the surface to melt out ice.
Refs: Factcheck 22 March 2019: ‘Is 3-5C of Arctic warming now ‘locked in?’
Appears phrase I originated years back, continues to make its way into the mainstream press now. Timely recent example. One among several:
‘Sharp rise in Arctic temperatures now inevitable – UN‘.
‘Climate Model: Temperature Change (RCP 2.6) – 2006 – 2100‘.
