Does all this mean we should do nothing in the near term about climate change?  No. But given the problems with Plan A, we clearly need a Plan B that broadens the climate policy envelope. By considering climate change as a wicked mess, climate change can be reframed as a predicament for actively reimagining human life. Such a narrative can expand our imaginative capacity and animate political action while managing social losses.

We should work to minimize our impact on the planet, which isn’t simple for a planet with 8 billion inhabitants.  We should work to minimize air and water pollution.  From time immemorial, humans have adapted to climate change.  Whether or not we manage to drastically curtail our carbon dioxide emissions in the coming decades, we need to reduce our vulnerability to extreme weather and climate events.

Lead and IQ

https://www.nbcnews.com/health/health-news/lead-gasoline-blunted-iq-half-us-population-study-rcna19028
so what did they use for their control group

Ive reread this several times and really dont understand how they calculated the amount of mental loss

I think one of the ways they can look at it is determining lead levels in topsoil. In areas with heavy lead exposure, i.e. vehicle exhaust has a lot of lead, that lead ends up falling into topsoil. Then they can look at aggregate IQ levels between areas of high and low lead levels, controlling for demographics (as much as possible), to try to determine correlation between lead levels and IQ. 

There's been a lot of study on this... The era of leaded gasoline correlates to a lot of bad effects. Crime, etc. One aspect of this is that lead levels tended to be highest in the areas of highest population density (obviously; there were more cars emitting lead there)... So it affected cities much more than rural areas. 

I put it in this topic because weather, climate and environment is the right place for discussion of pollution, and I think the effects of lead pollution during the era of leaded gas is not fully appreciated.

seems to me you would have to comare a sample of folks with high lead levels to a control group with normal lead levels

and to do this everyone would have to have taken a qualified IQ test

I dont see how they could have done this

I think an IQ of 100 is taken as the mean with a normal distribution around that.

One issue, I think, is a smart person who doesn't read well won't do well on any written test.

So, if we first focused on coal burning power plants, we could get a bigger bang for the buck as they pollute with normal pollutants, and coal is problematic to mine and the residual burned ash is also a problem.  The advantage of coal, aside from low cost, is it provides steady baseline power, something you need if other sources are intermittent.

The obvious replacement is more costly, but pretty obvious, though the shift to natural gas has been obvious over the years, making more of an impression in our mix than wind and solar.

UN secretary general: World is 'sleepwalking to climate catastrophe' | TheHill
UN secretary general: World is 'sleepwalking to climate catastrophe' | TheHill

“The world returned from [the COP26 climate summit with a certain naïve optimism” about achieving the goal, Guterres told attendees at the Economist Sustainability Summit. “Keeping 1.5 alive requires a 45 percent reduction in global emissions by 2030 and carbon neutrality by mid-century. That problem was not solved in Glasgow.”LEARN MORE

“According to present national commitments, global emissions are set to increase by almost 14 percent in the 2020s,” he added. “Last year alone, global energy-related CO2 emissions grew by 6 percent to their highest levels in history. Coal emissions have surged to record highs. We are sleepwalking to climate catastrophe.”


Yeah, I've been saying this for a while now.  And these are "commitments", pledges, not yet reality.

Yikes. My BIL moved to San Antonio a couple months ago, and my MIL and wife's stepdad are en route from Phoenix to Las Cruces today, and Las Cruces to San Antonio tomorrow because they're also moving. 

Did any of this hit SA?

San Antone is toward the southern end of that oval, and they've just dropped their chances of strong thunderstorms/supercells from 70% earlier today, down to around 30%.  Most of this should be north of them.

Which puts Austin well in the crosshairs.

Man, accurate forecast was accurate.  Multiple tornadoes in the Austin area and all up and down Central Texas.  One of them even struck Dell's Round Rock campus, a glancing blow that only broke some windows and tore up some trees and light posts.  Coulda been a lot worse.

Minimal injuries as far as I know, at least in the Austin area.  We had some major hail in parts of town that damaged a lot of vehicles.  I spent yesterday morning clearing out the garage so I could get both cars inside.
