How much will climate disruption cost?

Do you want to estimate the cost of Hurricane Dorian? Putting aside the awful, and immeasurable toll of raw and long lasting suffering, how many billions has, and will, Dorian cost? Not all of the storm's havoc is attributable to climate disruption but a substantial portion is.

Thanks to Wikipedia

When a politician such as Bernie Sanders, Jay Inslee, or Elizabeth Warren steps forward with a plan to address the crisis their plan is always evaluated and measured by how much it will cost. Rarely is the price of inaction, or insipid action, measured.

Four years ago the Economist took a shot at analyzing the potential cost of inaction to investors. They published a scholarly peer reviewed paper on the subject. Here's the first paragraph from the executive summary of that report:


"The asset management industry—and thus the wider community of investors of all sizes—is facing the prospect of significant losses from the effects of climate change. Assets can be directly damaged by floods, droughts and severe storms, but portfolios can also be harmed indirectly, through weaker growth and lower asset returns. Climate change is a long-term, probably irreversible problem beset by substantial uncertainty. Crucially, however, climate change is a problem of extreme risk: this means that the average losses to be expected are not the only source of concern; on the contrary, the outliers, the particularly extreme scenarios, may matter most of all."


The authors of the paper went on to say that by the year 2100 climate disruption could cause roughly $4.2 trillion, an amount equal to the total GDP of Japan, to be lost from the stock markets of the world. They point out that this amount only reflects the costs to privately held stocks. It does not reflect the cost to other sectors of the economy.


For example, a recent study by economists at the University of Chicago reports that Climate change could cost the U.S. up to 10.5 percent of its GDP by 2100 if average temperatures continue to rise at the pace that they have been rising in recent years.

So, the question is not, "What will a climate disruption plan of action cost". The question is: "Is this plans investment adequate to save humanity from global impoverishment?"

Let us all walk in the foot steps of John Lewis

By John King In Selma, Alabama, on Sunday, March 7, 1965, John Lewis, standing in the lead of a long line of marchers, looked down from the crest of The Edmund Pettus Bridge at the line of police armed with clubs, whips and truncheons and said, “I am going to die here.” Lewis intended to lead the marchers from Selma to the capital Montgomery, to demand access to voting for Black people in Alabama. Sheriff Jim Clark lowered his gas mask and led the deputies, some on horseback and some on foot, into the line of marchers. Under swinging clubs and hooves trampling, Lewis was the first to go down. Women and children were not spared. Choking and blinded by tear gas, they were struck by clubs and truncheons wrapped with barbed wire. Lewis, with a fractured skull and a severe concussion, almost did die. The nearby Good Samaritan Hospital did not have enough beds to care for the injured marchers. A nation watched in horror as news footage of that bloody day appeared on T...

Are we farmers, producers, or growers?

I was glancing at an analysis of a livestock market report recently. The author wrote that livestock markets were improving because demand for product was increasing. Now we’ve all been weaned on the milk of capitalist eonomics so in less than a heart beat I knew that increased demand for beef product units by consumers translated into better prices for beef producers. I was reading a piece of proposed legislation this morning that referred to the people who grow food as producers. Producers presumably grow products or product units, also known as food. There is a trade magazine called the Vegetable Grower. Please note; it is not called the Vegetable Farmer or the Vegetable Gardener. Recently a restaurant in Singapore had a couple of items on its menu with food names and food appearance but the material on the plate was a protein created in a laboratory. If these lab proteins catch on their production will be scaled up and industrialized and mass produced. So many hundreds of thousa...

Who do they represent?

Alexandria area State Representative Mary Franson has been in the news this week regarding her refusal to meet with a group of well mannered Alexandria high schoolers. My brother John sent the letter below to the Long Prairie Leader. It makes you wonder how many other politicians believe they represent only part of their constituency. -- ed. Dear Editor, It's a good idea to keep an eye on the legislators in order to see what kind of mischief they are up to.  Even if they are not from your district. You may remember Mary Franson; she was our representative until a few years back when things were redistricted and she was sent across the county line to Douglas County to represent the folks over there. So I have more or less kept my eye on Mary. She caught my attention this week with a Twitter exchange she had with the Student Democratic Society at Alexandria High School.  The students wanted to meet with her at her office out of a sense of civic responsibility...
