Permalink- Several studies found human sperm counts have declined world-wide
since the 1980s. We find here they have declined in "spooky
parallel" with the global increase in atm CO2 levels.
- Other studies have found hospital admissions for acidosis --
above-normal levels of CO2 in the blood -- in the US
have risen over the past 20y. Again we find the rise is in spooky
parallel with atm levels of CO2.
Yet another article on impacts of AGW on public health:
Unchecked Climate Change Could Triple US Heat-related Deaths, Warn Experts;
Know Who Is At The Highest Risk?
Times Now, 24 Sep 2024
If global warming continues the way it is now, the number of US citizens who
succumb to extreme heat will triple by mid-century, new projections estimate.
There are dozens of such items in the news. Also seen are articles
published by the World Bank and various UN organisations worrying
about the impact of heat on poorer populations in Africa and Asia.
But there is an even bigger impact. Just the atm CO2 levels seem to be
having an affect on human populations. Despite all the doggerel from
fossil-powered agents of misinformation, higher levels of CO2 are not
harmless to people. It's long been noted that even modest "office
levels" can dull humans enough to affect performance at work and on
test scores.
But there is yet another even more widespread effect. There are
suggestions atm CO2 levels are decreasing male fertility.
One study I looked at years ago found male sperm counts worldwide were
declining. The data looks like this:
Year Decrease in sperm count (%)
averaged over studies from many countries
1989 0
1990 -5
1991 -10
1992 -15
1993 -17
1994 -18
1995 -21
1996 -23
1997 -25
1998 -25
1999 -25
2000 -24
2001 -24
2002 -25
2003 -27
2004 -29
2005 -30
2006 -31
If we call 1989 "100%" and compare against atm CO2 levels measured at
e.g. Mauna Loa over the same period we find:
Year Av atm CO2(ppm) Spermcnt(%) Model
1991 355.608 90 83.6961**
1992 356.446 85 83.1578*
1993 357.1 83 82.741

2004 377.523 71 71.045
2005 379.796 70 69.8858
MODEL:
Durbin-Watson d = 0.812131
d < dL (1.160000): Positive auto-corr at 5%
(AUTO CORR CORRECTION; estimated rho = 0.593934)
y = 8.18813393e+08 * x^-2.74032121e+00
beta in -2.74032 +- 0.561669 (90% CI)
alpha in 20.5234 +- 1.35133
T-test: P(beta<0) = 1.000000
limits for alpha at 90.0% CI
Rank test: calculated Spearman corr = -0.968137
Crit val = 0.582500 2-sided at 1%; reject H0:not_connected
r2 = 0.82984011
I.e. the stats is convinced with 2 tests the atm CO2 is linked to the
observed global decrease in male fertility.
And as another added affect another project Quant Central did
processing for a few years back found that cases of acidosis may be on
the rise also related to increasing atm CO2 levels. Acidosis comes in
many forms but is essentially high levels of CO2 in the blood. It
seems fairly obvious if atm CO2 is rising -- up almost 40% since the
start of the Industrial Revolution in the 1850s -- then it should be
increasing in the blood of animal life on earth. One of the effects
may be decreased fertility (as above). But it can also affect people
with chronic conditions like diabetes, or just the frail and infirm.
Several studies have found hospital admissions in the US for one form
of the condition have been rising over time. Fortunately, the same
studies generally conclude that medical technology has improved over
time and fatalities related to diabetic acidosis (DKA) have actually
fallen. But it's the thought that counts. ;)
The numbers I had from a prev study look like this:
age-adjusted rates of US hospital admissions for DKA per 1000 capita:
2000 22
2001 23
2002 25
2003 27
2004 26
2005 23
2006 20
2007 25
2008 24
2009 20
2010 24
2011 25
2012 27
2013 26
2014 29
Which we can line up with atm CO2 levels again and get this kind of thing:
Year Av atm CO2 (ppm) DKA admiss Model
2000 369.550001 22 23.1756
2001 371.143333 23 23.3383
2002 373.279167 25 23.5564*
2004 377.522502 26 23.9897*
2005 379.795832 23 24.2219
2007 383.791667 25 24.6299
2008 385.604164 24 24.815
2010 389.898338 24 25.2535*
2011 391.652496 25 25.4326
2012 393.853327 27 25.6573*
2013 396.520002 26 25.9296
MODEL:
(No serial corr detected).
y = 1.021129e-01*x + -1.456016e+01
beta in 0.102113 +- 0.0753457 (90% CI)
alpha in -14.5602 +- 28.8627
T-test: P(beta>0) = 0.982628
Rank test: calculated Spearman corr = 0.700000
Crit val = 0.534000 2-sided at 5%; reject H0:not_connected
r2 = 0.40679959
I.e. for each ppmv of CO2 admissions have gone up ~1 per 10,000
capita. The stats is again better than 90% sure 2 different ways.
If diabetics are seeing an increase in blood CO2 leading to more
hospitalisations then it's a fairly sure bet it's affecting every man,
woman and child as well.
It certainly seems the little swimmers have been taking notes.
