AGRICULTURE REGENERATION


This Summary by DPearce © Sept 29, 2019. (The attached video lecture really gets interesting midway til the end). Overview: It was thought at one time that deherding lands would prevent desertation, but has proven to be the opposite. Also, grasslands are now purported as the way to store carbon likened as rainforests. Grazing herds on grasslands are the gist of the video's message, as a natural means in upgrading drylands & containing carbon. Current methods involve setting fires to crops, which release excess carbon and are contributing to global warming; furthermore, the soils are being overworked and more dry grasslands are appearing when herds were removed.

A timelapsed demonstration shows before/after clips how moving grazing cattle & goat herds were strategically placed on dry zones needing revitalization. The lecturer explains how natural compost is being generated. Supposedly, a crucial natural method vs typical methods of field fires set after harvest each year.

 Note, outside sources in opposition say there should be less herds, while promoting to eat less red meats, due to herd methane releases their contribution on global warming.

Listed below is the particulars on just how much damage cattle methane impacts the environment and why deherding was previously suggested (as well as, in err, as a way thought to  prevent drylands or overgrazing).
TimeForChange.org Are cows the cause of global warming?
"A cow does on overage release between 70 and 120 kg of Methane per year. Methane is a greenhouse gas like carbon dioxide (CO2). But the negative effect on the climate of Methane is 23 times higher than the effect of CO2." 

But, I must mention there is research & biotech experiments conducted for engineering - breeding herds for the purpose of minimized methane releases to reduce cattle's mark on global warming. Potential for reduced methane from cows "ScienceDaily
Jul 8, 2019 · Summary: Scientists have shown it is possible to **breed cattle to reduce their methane emissions**. ... A single cow on average produces between 70 and 120 kg of methane per year and, worldwide, there are about 1.5 billion cattle."


Feeding cattle additive digesters is one way that some cattle farms are handling cattle methane emissions.

I found other videos online also about using moving, grazing herds for desertation. It WAS a surprising learn!

TYPHOON 411



SUPER TYPHOONS TIED TO GLOBAL WARMING.

At this educational YT video, by BLUE GLOBE CHANNEL, learn what energizes typhoons & super typhoons (e.g. warm oceans & wind stalls) and explains why cyclones, typhoons, & hurricanes (same type storms, labelled differently by region) spiral around, caused by Earth's movement on its axis.
Per James P. Kossin, NOAA Hurricane Expert & Co-author of a June 2018 study, titled,
"A global slow-down of tropical-cyclone translation speed"
"global warming makes the global atmospheric circulation slow down." 

 From a Separate Sept. 2019 Article 

Why Are Hurricanes Like Dorian Stalling, and Is Global Warming Involved?

we can understand how STALLED STORMS are tied to global warming, by studying different mechanisms in the tropics and mid-latitudes. Per James P. Kossin, NOAA Hurricane Expert & Co-author of the June 2018 study, "global warming makes the global atmospheric circulation slow down," Kossin explained how some scientists are in agreement that "the overall slowing of winds is at least partly due to rapid warming of the Arctic."  The temperature differences in the Arctic and the equator fuel winds. As the Arctic warms faster than lower latitudes, the contrast in temperatures decreases, but so are wind speeds.

Kossin continues, "Tropical translation speed has decreased globally by 10 per cent over the period 1949–2016... the increase in tropical cyclones stalling is a global trend" with magnitudal variations by region considered consistent with "expected changes in atmospheric circulation forced by anthropogenic emissions."

Summary

Basically, studies reveal jet stream changes, wind stalls being associated with the Arctic & Equator's contrasting temps, humans equated with global warming effecting the Artic meltdown,... all of which are fueling super storms in our seas.
