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‘.
