Before you say, that’s cool and move on, think about that for a second. WE CAN MEASURE WINDS FROM SPACE! We can also measure temperatures,  humidity, the amount of dust in the air, and even how stressed the plants in a drought are. Oh, and NASA did it all (and went to the Moon and Mars, and launched 100 space shuttles), all on less money than we spent on the

Feb. 7 Bertha update: Two factors contributed to tunnel stoppage

WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all. They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was [...]

This has been a trying winter here on the east coast for working outside. I got spoiled by the last couple of winters, which were generally mild. Here's what has worked to keep me warm when the temperatures have hovered around zero (F), starting from the inside and working outside: 1. single-layer longjohns (I have a pair of the two-layer wool pants, but frankly, I can only wear so many

“Despite some difficulties, the project was able to drill down into the molten magma and control it; it was possible to set steel casing in the bottom of the hole; allowing the hole to blow superheated, high-pressure steam for months at temperatures exceeding 450 C, created a world record for geothermal heat.” Quoted from the

Premiering Next Week- Revenge of The Polar Vortex (Starring the Dogs of Winter)

It’s coming back. Will it be as cold as the last one at the beginning of the year? Too soon to say but there are growing signs it will last longer and may come in several waves. Numerical weather ensembles (See last two blog posts) are in remarkable agreement that the cold will return. Model guidance is indicating temperatures as much as 40 degrees below normal by later next week!

The seismic aspect of frost quakes 

Ontario-geofish [2014-01-03 23:39:00]  recommend  recommend this post  (31 visits) info
We may never get a good location for frost quakes, because of simple physics.  Nearly all the seismometers are in remote fields far from trees and electrical facilities.  The standard arrangement is to use a solar panel, and a satellite dish.  That means we can put them in anywhere. The downside happens during a miserable ice storm and when temperatures plunge down to the minus-minus zone.

I'm back from a cottage in Haliburton.  Wow it was -27 oC this morning!  I haven't been in these temperatures since the 70's when I used to go winter camping.  Of course, then it was -40, but who can tell the difference?  Now, since I put no weight on the 'momentum' of our last warming trend, I am convinced we are entering a new 70's-style cold time.  It will be fun to track the warmists

As the Earth warms, Arctic tundra rots

Melting ice caps may not be the only problem the Arctic has to worry about as the climate changes. As temperatures rise, permafrost melts earlier and stays wet longer. When plants and other organic material in the soil thaw, they decompose, releasing huge quantities of methane and carbon

Human activity changes the environment, as last week’s release of a report by the Intergovernmental Panel on Climate Change reminds us. But not all change is bad. One way in which animals and plants respond to warming temperatures, for example, is to move beyond their historical distributions, just as they do when they are transported to new regions by humans. The response of people who
