[geo] ISO/AWI 14082: Radiative Forcing Management-- Guidance for the quantification and reporting of radiative forcing-based climate footprints and mitigation efforts

2019-07-15 Thread Alan Robock

Does anyone know what this is?

https://www.iso.org/standard/68505.html

What authority does this organization have over anything?  Is it just 
the standards for reporting metrics?  It doesn't seem to involve 
governance.  Anyway, there is no such thing as SRM yet.

[geo] The climate crisis is about neutralizing acid

2019-07-15 Thread Ernie Rogers

The ocean surface and the atmosphere are in a near-equilibrium 
condition--the pH of the ocean and the CO2 concentration of the air are 
closely coupled.  The consequence is that the ocean is getting more acidic 
with rising atmospheric CO2.  If we raise the pH of the ocean surface, the 
atmospheric CO2 problem goes away.
 Interesting fact (recognized by many):  More than 99.9% of the earth 
is basic.  Only 0..1% or less is acidic and needs neutralization (the 
biosphere).  Can't we find a manageable way to apply enough base to the 
problem?  (I imagine it should take dispersal of about 1000 cu.km of 
ultramafics to do the job, but I am an optimist.)

[geo] CO2 is more about ocean change than climate change

We are in an ocean carbon age equal to the worst volcanic epoch on this 
blue planet. But we can save it.

1. Contrailscience.com

2. What is clarity?

3. Where? When? I have never heard this claim before. Please show us the data.

1. How can you tell the difference between clear weather and no contrails?

2. Do contrails affect weather clarity?

3. Is there a reason why it was the clearest of clear weather for 30 years?

Hi John ,

Inconveniently, they do both. They reflect and scatter incoming solar radiation
(cooling effect) but also absorb outgoing longwave (warming). At night they are
purely warming, but during the day the net effect can be either - depending
strongly on whether there are clouds beneath them (decreases cooling benefit),
the surface albedo (sea is dark so contrail benefits are greater), and the
surface temperature. Kärcher wrote an excellent review article in 2018
(Formation and radiative forcing of contrail cirrus) covering the degree of
uncertainty in all this - since we have very poor records of total coverage and
properties, the exact balance between warming and cooling is also highly
uncertain.

I now see in a recent post that contrails warm the earth.

Which is correct?
