Greenland: Ice Loss Accelerating
Greenland’s ice sheets contain enough fresh water to raise sea levels over twenty feet.
While this is not an immediate threat, the latest research shows that #Greenland’sGlaciers are shrinking at seven times the rate of just a few years ago, an average of 30 million tonnes an hour.
Fresh water entering the ocean from this melting has major implications for
the Atlantic meridional overturning circulation , or #AMOC, which is critical to maintain global weather patterns. Peter Wadhams, Emeritus Professor of Ocean Physics at Cambridge University and Climate Scientist, Paul Beckwith describe what is happening on this sensitive continent.

Peril at the Poles
As polar glaciers thaw, greenhouse gases sequestered in permafrost for thousands of years are being released at increasingly alarming rates. The exposed #Permafrost emits Carbon Dioxide, Methane and Nitrous Oxide, the two latter being far more potent than CO2.
A major Atlantic ocean current, the #AMOC, is showing signs of slowing down. If it shuts down, climate systems will be radically disrupted. Paul Beckwith and Peter Wadhams discuss the situation in the Arctic and in #Antarctica with host, Dale Walkonen.

Abrupt Climate Chain Reactions
To really understand the climate emergency, we need to look at the Earth system as a whole. In this video, #JanUmsonst and #PaulBeckwith tell us what’s happening with our planet, as the use of fossil fuels, and the misuse of land, lead us deeper into crisis.
The planet’s temperature is rising. Nowhere is this more evident than in our oceans which have absorbed 90% of the heat from industrial civilization. As sea surface temperatures rise, glaciers thin at both poles. Ocean salinity is altered, polar vortices shift , the AMOC slows. Changes can be sudden as one thing leads to another in disaterous chain reactions. Sea levels rise, storms get stronger and more frequent, and weather patterns become unpredictable.

The Big Freeze A New Reality
As the rapidly warming Arctic pushes its glacial weather south, stretching the polar vortex, more extreme and dangerous cold blankets North America. It’s not a passing event. As nighttime temperatures plunge into the single digits, heavy snow remains frozen. In this video, Climate scientist, Paul Beckwith explains how climate change is bringing colder winters and offers some suggestions for people who may not be prepared.
What can you do when temperatures plunge so drastically?
If you must go outside, to avoid hypothermia, layer warm clothes, wear insulated gloves and hat, and protect your face and neck with a scarf
In your home,
You might let indoor faucets drip slightly to prevent pipes from freezing
Cover doors to the outside and to rooms you don’t heat with blankets
Close curtains to retain heat
Plug electric heaters into the wall, not to an extension cord
On the road,
Don’t go if you don’t have snow tires and roads are icy
Keep extra warm clothes in your car in case of a breakdown
Have emergency kit, food and water in your car,
Keep your cell phone changed and in a warm place
(Batteries can fail in extreme cold)
Check on your neighbors!
