Smoke Covers Much Of Siberia

Smoke covers much of Siberia, as shown by the NASA Worldview image dated July 25, 2019.

The enormous intensity of the fires is illustrated by the image below, showing carbon monoxide (CO) levels as high as 80,665 ppb on July 25, 2019.

The image below shows that, at that same spot on July 25, 2019, carbon dioxide (CO₂) levels were as high as 1205 ppm.

The image below shows that aerosols from biomass burning were at the top end of the scale.

When soot from fires settles on snow and ice, it darkens the surface, resulting in more sunlight getting absorbed (instead of reflected back into space, as was previously the case), thus further speeding up the melting.

The loss of sea ice north of Greenland is particularly worrying, since this is the area where once the thickest sea ice was present. The image below shows the situation on July 24, 2019.

The image below shows the sea ice disappearing north of Greenland and Ellesmere Island on July 25, 2019.

The huge recent fall in sea ice volume is illustrated by the graph below, by Wipneus.

The naval.mil animation below illustrates the rapid fall in sea ice thickness, showing 30-day period including seven forecasts up to August 1, 2019.

The combination image below shows sea ice thickness forecasts for July 25, 2019, and for August 1, 2019.

The video below, by Robin Westenra, further illustrates our predicament.

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.

Austerity-A Fancy Word for Destitute.

The reason for this post is not for the folks who have been caught in the first wave of personal economic hard reality, but the next wave. Regardless of the optimism espoused by grinning leaders and sycophant press, we are entering the final stage of global economic collapse. It began in 2008 and was forestalled for five years with fudge putty, but the weight of global indebtedness cannot be propped any longer and the final crunch is imminent. Austerity measures herald the final throes. Indications of coming austerity. Austerity measures are the final last ditch effort, futile or not! Back in the day many of us old-timers went through periods of "hard-times". In retrospect I realize there is no comparison to yesteryear hard times and today's version. Back then, expectations were never very high for the working class, there were no sophisticated systems or conveniences anyway. In fact the difference between being "set" or not was about having treats or not. Si...

Terrifying Arctic methane levels

A peak methane level of 3026 ppb was recorded by the MetOp-B satellite at 469 mb on December 11, 2021 am. This follows a peak methane level of 3644 ppb recorded by the MetOp-B satellite at 367 mb on November 21, 2021, pm. A peak methane level of 2716 ppb was recorded by the MetOp-B satellite at 586 mb on December 11, 2021, pm, as above image shows. This image is possibly even more terrifying than the image at the top, as above image shows that at 586 mb, i.e. much closer to sea level, almost all methane shows up over sea, rather than over land, supporting the possibility of large methane eruptions from the seafloor, especially in the Arctic. Also, the image was recorded later than the image at the top with the 3026 ppb peak, indicating that even more methane may be on the way. This appears to be confirmed by the Copernicus forecast for December 12, 2021, 03 UTC, as illustrated by the image below, which shows methane at 500 hPa (equivalent to 500 mb). Furthermore, ...

Women and children overboard

It's the Catch-22 of clinical trials: to protect pregnant women and children from the risks of untested drugs....we don't test drugs adequately for them. In the last few decades , we've been more concerned about the harms of research than of inadequately tested treatments for everyone, in fact. But for "vulnerable populations," like pregnant women and children, the default was to exclude them. And just in case any women might be, or might become, pregnant, it was often easier just to exclude us all from trials. It got so bad, that by the late 1990s, the FDA realized regulations and more for pregnant women - and women generally - had to change. The NIH (National Institutes of Health) took action too. And so few drugs had enough safety and efficacy information for children that, even in official circles, children were being called "therapeutic orphans." Action began on that, too. There is still a long way to go. But this month there was a sign that ...
