Climate change adaptations - native communities

When I started this blog I explained it was inspired by the Mohawks' work to preserve ash trees which are a species threatened both by Emerald Ash Borer and climate change.

Here's a link to more examples of confronting climate change in other indigenous communities.

Something mainstream media usually misses in the solar cycle

It turns out that geomagnetic storms and electron fluxes occur predominantly before or after the famed high-energy solar activity part of the sun's cycle, per one of NOAA's nifty reports, graph on page 3.

Media attention to the solar cycle has been driven by climate change deniers who try to deceive people into believing that heat waves and droughts are only cyclic, ignoring the overdrive of anthropogenic global warming.  That denier deception is far more sinister than the, "Ignore the man behind the curtain," moment in the Wizard of Oz, even though both are attempts to deflect attention away from what is really happening.

The earth is accumulating heat even during the slow parts of the solar cycle, important to mention.  Yet mainstream media should also pay attention to other aspects of the solar cycle.

Why would we care about it?  Geomagnetic storms, proton surges and electron fluxes, what about them?  They affect electronics. They affect power grids and pipelines.  As we turn away from coal and oil (and I hope nuclear) we have protect and sustain the electronic culture and the devices that displace carbon energy.

If a man eat of the fish..

ProMed has carried a report that could be rather ominous.  If the prion that can give deer Chronic Wasting Disease (CWD) can be transmitted by something as common as alfalfa, what does that suggest about pathways to other animals such as cows, humans, or even fish fed on animal protein?   In Shakespeare's Hamlet, the prince muses, "A man may fish with the worm that hath eat of a king, and eat of the fish that hath fed of that worm."

Uptake of prions into plants
Session title: Current science of chronic wasting disease: what have we learned in the last 5 years?
Author: Christopher Johnson, US Geological Survey, Madison, WI

Chronic wasting disease (CWD) and scrapie-infected animals shed infectious prions during both the preclinical and clinical phases of disease. Contamination of environments with prions released from animals or from infected carcasses appears to contribute to the transmission of these diseases.

Previous work has suggested that soil may serve as an environmental disease reservoir. Vegetation is ubiquitous in CWD-contaminated environments and plants are known to absorb a variety of substances from soil, ranging from nutrients to contaminants.

The uptake of proteins from soil into plants has been documented for many years and we have been investigating the uptake of prions into plants in vitro. Using laser scanning confocal microscopy, we observed root uptake of fluorescently-tagged, abnormal prion protein in the model plant thale cress or mouse-eared cress (_Arabidopsis thaliana_), as well as the crop plants alfalfa (_Medicago sativa_), barley (_Hordeum vulgare_), and tomato _(Solanum lycopersicum_). Using serial protein misfolding cyclic amplification, a sensitive biochemical prion detection method, we have found evidence of prions in aerial tissues from these species, as well as maize (_Zea mays_). Both stems and leaves of _A. thaliana_ grown in culture media containing prions are infectious when injected into mice and oral bioassays are underway for _A. thaliana_ and other plants. Our results suggest that prions are taken up by plants and that contaminated plants may represent a previously unrecognized risk of human, domestic species, and wildlife exposure to CWD and scrapie agents.
