20 min. video. My polar vortex PhD thesis: explained

Image
In this video I briefly explain, in some detail, my PhD thesis in atmospheric physics, specifically looking at the dynamical coupling of the stratosphere and troposphere. I had a great time doing this work at the University of Exeter, as documented in my vlogs, and so I wanted to once and for all show you what I accomplished! There is an awful lot in my thesis that I didn't mention in this video, mostly to keep things simple and to keep the running time down. Most notably I don't critique or really statistically verify a lot of the assumptions I made and methods I used in the thesis. I also completely ignore the difference between Ertel and QG PV.

22 min. video. W5: What happens when the permafrost thaws?

Image
Almost half of Canada sits on permanently frozen land called permafrost, but climate change is causing it to thaw and erode rapidly. W5's Avery Haines investigates a looming ecological disaster that poses a threat to the entire world.

9 min. video. What's hidden under the Greenland ice sheet? | Kristin Poinar

Image
The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds a Lake Tahoe-sized volume of water from the summer melt. Does this water stay there, or does it find its way out to the ocean and contribute to global sea level rise? Join glaciologist Kristin Poinar for a trip to this frozen, forgotten land to find out. "The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below". "The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick". So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.) A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of...

Helpful comments on Arctic climate crisis

The earth has enough for every man's need, but not for every mans greed." - Gandhi Comments on sea level rising Sea level rise might take a while, but we already feel the effect of changing weather patterns resulting in forest fires etc. The domino effect is in full motion.  https://arctic-climate-crisis.blogspot.com The sea level is also rising by the fact that water expands the hotter it becomes. When the ocean's waters heat up this phenomenon adds to the overall height of the increase. Comments about politicians Never confuse politicians with leaders. If doing nothing could lead us to a solution, the US senate would be the perfect organization to lead mankind there. Politics is why we are where we're at. Same with the pandemic. Keeping the corporate profit machine going is all that matters to politics. Nice talk won't get us nowhere, it never did. It's called PR, aka marketing. See "the Century of the self", an old but excellent BBC documentary. ...
