LECTURE ONE: How Abrupt Climate Change is Redrawing the Map // Feb 20, 2019

In my last video I skated on Ottawa’s frozen Rideau Canal and RANTed about abrupt climate change redrawing planetary maps. Now, in the next few video LECTUREs, I show you new peer reviewed scientific papers (free) supporting what I RANTed about.

 

Tropics are growing by 30 miles (0.5 degrees latitude) per decade; Hadley Cell expansion, but a “tropic squeeze” shrinking is occurring in equatorial regions with heavy rains (Inter-Tropical Convergence Zone, or ITCZ). Since 1920, Sahara Desert has grown by 10%, advancing as much as 500 miles northward.

LECTURE TWO: Abrupt Climate Change Disruption of Your Life // Feb 21, 2019

People used to have to move to experience a new climate. Now, you just have to wait a few years. The North American 100th meridian separating the dry West from the wetter East shifted 140 miles east since 1980.

 

US Tornado Alley has moved 500 miles east in 30 years. Dorothy, it’s no longer in Kansas. Plant Hardiness Zones migrate Northward 13 miles per decade.

Canada’s Permafrost line has moved 80 miles north in 50 years. Wheat Belts are march poleward up to 160 miles per decade; southern Australia’s is pushing into the sea.
———- ———-

LECTURE THREE: Your City’s Climate is Shifting Beneath Your Feet // Feb 22, 2019

Thousands of northern lakes no longer freeze up. Amplified warming at high latitudes changed annual ice cover to intermittent or no ice when mean annual surface air temperature exceeds 8.4 C, subject to other factors (lake depth; size, lake elevation; coastline complexity).

A peer-reviewed science paper on “climate analogues” shows how climate in North American cities is shifting south-south-west by an average of 500 miles within a generation. See how fast and far your own cities climate is going.

LECTURE FOUR: Four-Fifths of Coldest Arctic Air Volume has GONE // Feb 22, 2019

In this video, I mostly talk on how the coldest Arctic air volumes are gone. In fact 80% of the coldest air masses are no longer there. Not just cold air at the surface, but cold air all the way up.

As the entire Arctic continues warming at rapidly accelerating rates it is only a matter of time when sea-ice no longer forms; Greenland melting will cause rapid sea-level rise. Extreme weather severity, duration, and frequency will also skyrocket, and unprecedented weather events like snow in deserts will occur.

Ref:  Indicators and Trends of Polar Cold Airmass: Kanno, Walsh,  Abdillah, Yamaguchi and Iwasaki, Published 11 February 2019.  Abstract:

Trends and variations in the amount of cold air mass in the Arctic and the Northern Hemisphere are evaluated for the 60 year period, 1959–2018. The two indicators are polar cold air mass (PCAM), which is the amount of air below a potential temperature threshold, and negative heat content (NHC), which includes a weighting by coldness. Because the metrics of coldness are based on multiple layers in the atmosphere, they provide a more comprehensive framework for assessment of warming than is provided by surface air temperatures alone‘.

Impact of Abrupt Sea-Ice Loss on Greenland, Radio EcoShock Interview

Arctic Blue-Ocean-Event Consequences for Greenland: 1 of 2 // Feb 15, 2019

Between 60,000 and 22,000 years ago there were numerous abrupt temperature fluctuations recorded by oxygen and nitrogen isotopes (paleo-thermometer proxies) in Greenland ice cores [1].  Temperatures over parts of Greenland rose by up to 16.5 C within a decade or two, in the largest of these so-called Dansgaard-Oescher (D-O) Oscillations.

I chat on the latest science, about how a lack of Arctic sea-ice was the primary factor. This is crucial info to help us figure out what will happen to Greenland when we have no surrounding sea ice left.

[1] Ref: Arctic sea ice loss in the past linked to abrupt climate events, February 11, 2019, British Antarctic Survey: Lead author, Dr. Louise Sime, a climate scientist at BAS says:

For years scientists have been puzzled about the correlation between Arctic sea ice loss and the extreme climate events found in the ice core record. There were at least four theories being mooted and for two years we’ve been investigating this problem. I’m delighted that we have proven the critical importance of sea ice using our numerical model simulations.

“The summer time sea ice in the Arctic has experienced a 40% decline in the last few decades, but we know that about two thirds of that reduction is caused by human-induced climate change. What we now need to determine is, what can be learnt from these past sea ice losses to enable us to understand what might happen next to our climate3.”

Always a favorite, interview posted on February 14, 2019, by Radio Ecoshock, with master interviewer, Alex Smith.  The End of Ice:

Greenland, Antarctica, South America, the Himalayas – it’s all going, the ice is leaving the Earth.

This is a whirl-wind roundup of new science with Ottawa climate expert Paul Beckwith. We talk pollution (is it saving us?), vanishing glaciers, Tasmanian dry lightening fires, James Hansen’s latest, tech to draw down carbon dioxide, and why this scientist made 500 videos to educate and warn the public via YouTube‘.

Alpine Glacier Melt-Out at Third Pole, Amplified Warming at High Elevations, Feedback Mechanisms

Alpine Glacier Melt-Out at the Third Pole // Feb 12, 2019

Since 1970 about 15% of the glacial ice has melted out at the “Third Pole”; the extensive region with high elevations in Asia that encompasses the Himalayan Mountains and the Tibetan Plateau. Warming is being amplified by a little-known feedback called Elevation Dependent Warming (EDW). A conservative estimate is that we will lose one-third, one-half or two-thirds of the ice with average global temperature change of 1.5 C, 2.0 C, and 4.0 C, respectively, threatening the water supply (and food supply) for up to 2 billion people.


———- ———-
Amplification of Warming at High Elevations // Feb 13, 2019

In most (but not all) high-elevation regions, like the Third Pole (Tibetan Plateau; Himalayan Mountains), Antarctica, Greenland, Rockies, Alps, etc. the higher up you go, the greater the rate of warming. This is not commonly known, but the rate of temperature rise is about 2x, 3x or even greater, at higher altitudes than at lower altitudes, in a phenomena called Elevation Dependent Warming (EDW); clearly analogous to greater warming at higher latitudes. This is bad, especially for Greenland, Antarctica, as well as for the 2 billion people using Third Pole runoff.


———- ———-
Feedback Mechanisms Amplifying Warming in Alpine Regions // Feb 13, 2019

In the previous video I described how most alpine regions are warming two to three times faster at high elevations versus low elevations (and global average warming rates). Now I chat about feedbacks and processes that cause this, and how they vary with seasons and different regions. Albedo feedback, similar to that causing polar amplification, is one effect; others include upward creep of snow and tree lines, water vapour increases, cloud changes, aerosol loading changes, and both short-wave and long-wave radiation effects at altitude.

Surprising Effects: Glacier Melt, Mayhem Down Under, Argentina Heat, Tasmanian Fires, Land vs. Water Temps

sgriryiyiyuyiuiu

Non-Intuitive Consequences of Rapid Melt in Greenland and Antarctica: 1 of 2 // Feb 8, 2019

Glaciers on Greenland and Antarctica are rapidly melting due to Abrupt Climate Change, and melt rates are doubling with a period of roughly 7 years.  This is exponential, after:

  • 7 years melt rates are double (2x), after 14 years rates are 4x, after 21 years rates are 8x, etc.

In this video and the next I, discuss consequences that are rarely considered, like

  • reduced gravitational pull near the glaciers, isostatic rebound, and
  • reduction of vertical ocean mixing from surface freshwater lensing effects, leading to: increased basal ice sheet melting.

———- ———-

Surprising Effects from Rapid Glacier Melt in Greenland and Antarctica: 2 of 2 // Feb 9, 2019

Ref:  Global environmental consequences of twenty-first-century ice-sheet melt: Golledge, Keller, Gomez, Naughten, Bernales, Trusel, Edwards.  Nature Volume 566, pages 65–72, 2019. Published: 06 February 2019.

Government policies currently commit us to surface warming of three to four degrees Celsius above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. … Here we show, using simulations of the Greenland and Antarctic ice sheets constrained by satellite-based measurements of recent changes in ice mass, that increasing meltwater from Greenland will lead to substantial slowing of the Atlantic overturning circulation, and that meltwater from Antarctica will trap warm water below the sea surface, creating a positive feedback that increases Antarctic ice loss.’

Mayhem Down Under: Atacama Desert Waterfall; Argentinian Heatwaves; Tasmanian Dry Lightning Fires // Feb 7, 2019

Climate Mayhem is hitting many regions in the Southern Hemisphere. A misconception is that the bottom of the planet is more immune from rapid climate disruption due to its remoteness from the Arctic.

Even many 1 Percenters and 0.1 Percenters are confused, and preparing Bug-Out places in New Zealand; they are sadly mistaken.  I discuss:

  • torrential rains and waterfalls in the Atacama Desert in Chile (driest Desert in world);
  • heatwaves at the Southern tip of Argentina, and
  • unprecedented wildfires from “dry lightning” in old-growth pristine forests in Tasmania.

Global Average Temperature Rising About 3x Faster Over Land Than Water // Feb 7, 2019

Last year (2018) was the 4th warmest year, following behind El Niño influenced years 2015 (3rd), 2016 (1st), and 2017 (2nd). An El Niño may develop this year (65% chance) but is not likely to be super-strong, like that in 2015 and 1998.

Since 1970, average global temperatures are rising an average 0.17 degrees C per decade, but that slope is increasing. Rise over the land (0.27 C per decade) is almost 3X faster than that over the ocean (0.10 C per decade).  Land at high latitudes gets a double whammy, due to polar temperature amplification.

Huge Cavity Melted Out in Antarctic Glacier: Part 1 of 2 // Feb 4, 2019

A huge cavity–4 km wide by 10 km long by 300 meters high–has melted at the glacier base in only 3-5 years.  Total melt of west Antarctic glaciers:

  • Would raise global sea levels about 5 meters;
  • Greenland glacier melt would add 7 meters;
  • East Antarctic plus mountain glacier melt would add 60 meters (total about 72 meters = 238 feet).

39994470000_a390539e96_b.jpg

I discuss how melt rates of Antarctica glaciers are rapidly increasing due to warm salty ocean water incursions under the ice; in fact under Thwaites Glacier in west Antarctica an enormous hole— 4 km w x 10 km L x 300 meter H–has appeared in only a few years.

gjtstjryjtyjeryrtjyhuyjuyj

Ref:  Huge cavity in Antarctic glacier signals rapid decayA gigantic cavity – two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall – growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers’ undersides in calculating how fast global sea levels will rise in response to climate change.

Researchers expected to find some gaps between ice and bedrock at Thwaites’ bottom where ocean water could flow in and melt the glacier from below. The size and explosive growth rate of the newfound hole, however, surprised them. It’s big enough to have contained 14 billion tons of ice, and most of that ice melted over the last three years’.

Polar Vortex and Australia Scorched: Three Videos, Risks, Gists, Mayhem

   

Chat on Enormous Risks of Rapid Climate Disruption: 1 of 3 // Jan 25, 2019

Ongoing 2019 climate disruption is fast and furious. Abrupt climate system change cares not about human affairs, structures, politics, our livelihoods, and our precious but precarious civilizations. Disruption accelerates at ever faster rates wreaking havoc on our lives, with huge consequences. Media coverage on climate disruption, weather extremes, etc. in the main-stream is better, but often inaccurate; while risks and consequences are significantly downplayed.

Abrupt Climate Mayhem Mash: 3 of 3 // Jan 27, 2019

Quote from Carl Sagan’s The Demon-Haunted World: Science as a Candle in the Dark

I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness…

The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance.
