    "reached the point of no return".  Atmospheric CO2 is unstoppably on course for 450ppm within 20 years, without even counting soon to begin "natural" releases of CO2 and methane from melting permafrost and sub-sea clathrates.  When those begin (within a decade, I expect) their effect will dwarf any plausible reduction of the so-called "SLCP" (most of which are sourced in countries which simply cannot afford to do anything about them now anyway).  

    China, India, Indonesia and other major diesel exhaust polluters would love to reduce that pollution for reasons completely independent of climate change . . . but cannot come close to affording replacement of the current fleet of diesel vehicles . . . it will be a 20-40 year project even if they start today.  All their capital is going instead into CO2 spewing coal fired power plants necessary to meet currently unmet (and growing) electricity demand.  The (relatively minor) effect of reducing "black carbon" on global warming is simply not in their economic calculus.  I'm sure they'd be willing to give it a try, though, if you're willing to send the money . . .

    •  Yes, it's irreversible but it can always get worse (9+ / 0-)

      Our understanding & models are inadequate to predict the details. We know bad things will happen but there's a big difference between the Pliocene, the Miocene & the PETM.

      Then there's the end Permian extinction event.

      Before that there were apparently extreme oscillations between snowball earth modes and extreme greenhouse modes.

      look for my eSci diary series Thursday evening.

        that will be determined by gross CO2 emissions and what happens with (the extent of) the Arctic permafrost and clathrate emissions, not by minor stuff "on the margin" like the "SLCP".  

        Managing SLCP in the short term might make a difference if coupled with a massive effort  to manage the important things, but by themselves they hardly matter . . . and the social and economic costs, coupled with the improbability of meaningful benefit, make the effort counterproductive, since it distracts from addressing the real issues and serve only to defer real solutions.

              after reading them,,,fast because they are so spare....all you do is gloom & doom no solutions no issues...nothing just gloom & doom

                pretending things "ain't so bad after all", and I treat climate change as a serious issue, not just a "platform" to flog a food fetish, if that's what you mean . . .

                If there's anything incorrect in those diaries why don't you point it out?  

                As for "solutions" (to the extent that there are any) . . . those power plants all have to be built . . . the people of China and India need them.  They do not have to be fired by coal, oil or natural gas.  And transportation fuel can be carbon-neutral synthetic, if a carbon free energy source is used to produce it.  Even sequestration of CO2 already in the atmosphere, to get back below 350ppm, is possible (technologically feasible) with a carbon free source of process power.  Some portion of synfuel production and sequestration can be bio/solar . . . it's a convenient way to de-oxidize the carbon prior to complete reduction.
