Solarpunk author and friend of the blog Andrew Dana Hudson has a long article in Jacobin this week arguing that society needs to *think bigger*. 

Halting global warming at 1.5 degrees isn’t the same as actual climate repair.  Carbon removal though all possible avenues - natural carbon sinks, regenerative agriculture, better soil management etc are all necessary but not sufficient. 

He argues that though the deployment of cheap, decentralised. renewable technologies like wind and solar - energy intensive technological projects like direct carbon capture will increasingly become more viable. 

This piece is a brilliant example of ‘Yes, and’ thinking for climate solutions

Glomerulus secretes renin, vasoconstricts to increase blood pressure.

Erythropoietin stimulates the bone marrow to produce more red blood cells.

1,25-dihydroxyvitamin D activated in kidney.

Renal disease decreases glomerular filtration and creatinine clearance rate (labs: GFR, BUN, creatinine. BUN and Cr elevated.

In acute kidney injury, a BUN:Cr of 20:1 indicates a pre-renal state in which BUN is increased due to acute kidney damage. AKI may be reversible, not requiring dialysis.

Reduced BUN reabsorption indicated by a BUN to creatinine ratio of less than 10:1, suggests need for dialysis.

Renal solute load = solutes excreted in 1L of urine. MAIN SOLUTES: nitrogen and sodium.

Anemia, upset blood pressure, and decreased activation of vitamin D involved in renal insufficiency (due to the hormones released by kidney and hypothalamus).
