Global Warming / Climate Changes Pt. 21

the concept of cascading tipping points not only applies to climate sensitivity but also to coming potential society instabilities, as discussed in the linked article:

Lost Cities and Climate Change

by Kate Marvel (2019)

https://blogs.scientificamerican.com/ho ... ;text=Lost

… the adversity brought by climate change caused societies to break apart, magnified pre-existing divisions, and made desperate people easy prey for dangerous people.

“The climate has changed before,” say people who want to minimize the scale of the current challenge. I have never understood how anyone could find this comforting. The natural climate changes that have shaped human history have almost always been smaller and more regionally contained than the large-scale human-caused change we are currently experiencing. And even these changes have provoked suffering, scapegoating, and the collapse of civilizations.

I am often asked what frightens me most about climate change, whether I lie awake at night thinking about ocean hypoxia or arctic permafrost or other feedback processes that could turn a bad thing into a catastrophe. I am scared of the physical changes that await us on a warming planet, but the most important feedback process is the least well understood. The scariest thing about climate change is what it will make us do to each other.

While we're talking about agriculture, I found this:

Dicamba revisited: Will corn be the next herbicide debacle?
https://thefern.org/ag_insider/dicamba-revisited-will-corn-face-the-same-damage-as-soybeans/

Somehow, Dicamba (Round-up, I think) is able to spread very easily geographically. Does the weather affect this? Heat and evaporation? Possibly.

Why NOTHING will be done to avert rapid climate change:

Basically it requires a new mindset other than: me, me, I want it NOW, of Western Civilization. It goes against our social DNA. It cannot be rewired in just the few generations that we have had since being warned.

Why nothing can be done to avert climate change. Welcome to a glimpse of the Plutocene - what follows our Anthropocene (or just replaces the name, as it is happening so quickly).

"Hope, I try to avoid it like the plague!"

"We live in a futuristic bubble."

"Get out the champagne for everything we've enjoyed!"

Well, the last is my own sentiment.

Planning for global warming:

1. Acquire lawn chair.
2. Lay in supply of popcorn and beer.
3. Identify a location for lawn chair with a good view of the action.
4. Watch the fur fly.

Oh, I never forget.

Think of the humor as whistling past the graveyard ... although I'm still hopeful that they'll be able to keep the lights on and the convenience stores full of cheese doodles until I'm safely in the grave.

And the truly terrifying thing ... population is still going up, energy consumption is still going up. We haven't even reached the start of the downslope yet.

Research: Link Between Increased Atmospheric Vapor Deficit and Worldwide Loss of Vegetation


https://phys.org/news/2019-08-link-atmo ... dwide.html

Scientists have been studying the possible repercussions of global warming for several years, and suggest it is likely to lead not only to warmer temperatures, but also changes to weather patterns.

One such weather change not often mentioned is VPD, which is the difference in air pressure due to water vapor during fully saturated times versus times when it unsaturated. When VPD is increasing, there is less water in the air. VPD is important because of its impact on plants. When VPD rises a certain amount, plants react by closing their stomata, the pores in their leaves, to prevent water loss. But this also shuts down the release of oxygen and the absorption of carbon dioxide—partially shutting down photosynthesis and slowing growth. In this new effort, the researchers wondered if there might be a connection between observed losses of vegetation worldwide and changes to VPD in some parts of the world.

To find out, the researchers obtained datasets that included observation information from across the globe going all the way back to the 1950s. When focusing on VPD, they found that prior to the 1990s, VPD increased only slightly. But after 1998, the VPD grew quite dramatically—by up to 17 times over the next several years in some places, and it remained at those levels. They also found that over half of all vegetated land on the planet experienced a rise in VPD. The researchers also found that the upswing in VPD occurred in lockstep with the rise in global temperatures and the decrease in worldwide vegetative cover.

They suggest that global warming is pushing VPD ever higher, resulting in more loss of vegetation—and because the planet is growing hotter, they predict that VPD will continue to increase, as well, resulting in diminishing vegetative cover.

But why should that be the case when there are plenty of people with very deep pockets and influence at the highest tables who have very strong vested interests in disproving the theories of Global Warming True Believers? Doesnt add up to me.

Tanada has been good enough to regularly update us on arguably the most important numbers in the history of life on the planet--atmospheric CO2 levels--which of course have been increasing on an upward ('Keeling') curve for decades now.

And, in spite of there needing to be exponential growth in CO2e levels for there to be a linear growth in global temperatures, in fact global air temps have also seen and upward curve over the last half century, with each 30-year rate has been increasing starting with 1970-1999, according to BEST.

"...the measured ocean heat content is rising faster than consensus climate scientists previously assumed; particularly in the Southern Ocean. This confirms both that climate sensitivity is currently higher than consensus climate scientists have been assuming, and that the WAIS has a greater risk of collapse this century than previously assumed:"

Ocean heat hits record high: UN

https://phys.org/news/2019-03-ocean-high.html

"2018 saw new records for ocean heat content in the upper 700 metres," a WMO statement said.

The agency said the UN had data for heat content in the upper 700 metres (2,290 feet) of the ocean dating back to 1955.

Last year also saw new heat records for the ocean's upper 2,000 metres, but data for that range only goes back to 2005.

The previous records for both ranges were set in 2017.

UN Secretary-General Antonio Guterres described the latest findings as "another strong wake-up call" for governments, cities and businesses to take action.

"It proves what we have been saying that climate change is moving faster than our efforts to address it," he said at UN headquarters in New York.

The WMO report said the highest rates of ocean warming are occurring in the southern ocean, where warming has also reached the deepest layers.

They aren't really the problem. There are two main problems that need to be addressed.

The first problem is that virtually everyone, from the poorest to wealthiest, is dependent on our modern society, which is mainly based on energy from fossil fuels. Its extremely difficult and expensive to decarbonize the global economic system. There is lots of talk about it, but virtually nothing concrete has been done, as evidenced by the fact tha global CO2 emissions continue to rise each year.

The second problem is that the majority of carbon emission increases today are coming from China and India, and they were specifically exempted from any obligation to cut CO2 emissions in the bilateral Us-China climate that Obama signed with China in 2015, and then again in the 2016 Paris Accords. The world basically committed itself, by treaty in the Paris Accords, to allowing China and India to produce unlimited amounts of CO2.....and they''re doing their best to take advantage of that.

Cheers!

Recently there was an article about planting trees to stop climate change. Here is a response....

Lewis also dismisses the claim, by Bastin’s co-author Thomas Crowther, that “forest restoration is the best climate change solution available today.”

“That is emphatically not correct. The best solution for climate change is to keep fossil carbons in the ground,” Lewis says. Other experts have also raised concerns that the hype around Bastin’s study is creating misconceptions about the problem and primary solution, which could be problematic in the long-run. They fear a focus on tree planting could distract policy-makers from acting on other efforts to reduce carbon emissions and stop climate change.


Bold is mine.

http://blogs.discovermagazine.com/crux/ ... V_V-CR4FR4


This is not to dismiss the idea of planting trees or better yet retaining forests.

It is within reach of most of us to buy a few acres of forest, individually or collectively, to protect it from “development.”

I would like to see some tax relief for protecting wooded land. I spend nearly $2,000/year in taxes to protect my 168 acres.

Panama is not self sufficient in beef production so there is a property tax exemption as an incentive for all cattle farmers. The previous owners of our reserve were cattle farmers and set up this exemption. We removed livestock and are reforesting close to 100 acres but we keep around 20 head of cattle and enough pastures to continue to qualify for this tax exemption. The government does NOT offer this incentive for reforestation which is unfortunate.

Se we pay no property taxes because we keep farting cows.
