Took our boat out this AM for a little fishing. Called it off about 9 am, too windy and rainy and the fishing wasn’t good.

what kind of sled do you run these days Marcus ? 
Sorry just saw this.  We're now the proud part-owners of a Mastercraft X45 wakeboarding/wakesurfing boat.  It's huge, plenty big enough for the kids and lots of friends.  And it throws a really great wake for wakeboarding and surfing.

Terrible wake for actual skiing though.  I need to find a friend with an 80s Correctcraft or something.

Luckily the rain held off and we got about 5 great hours on the water, before coming back in town for my folks' annual Hatch green chile rellenos.  Man those were tasty!

New climate law has bipartisan roots — we need leadership from both parties to realize its potential | The Hill


I have looked for how many degrees C this new climate (etc.) bill will reduce warming long term.  I can't find an estimate.  It should be pretty easy to contrive.  I asked the MIT Climate Group to produce one, but they never responded.

I suspect I know why.

The one in orange has an 80% chance of forming into the next storm over the next 5 days, which would be Danielle.

U RAH RAH! WIS CON SIN!

https://www.wsfa.com/2022/08/26/least-active-start-atlantic-hurricane-season-30-years/#:~:text=2022%20is%20now%20officially%20the,down%20as%20a%20record-holder.&text=One%20way%20to%20measure%20how,something%20called%20accumulated%20cyclone%20energy.

A typical hurricane season features about 122 ACE. That number comes from averaging the amount of ACE that occurred each year from 1991 to 2020. By August 26th the average Atlantic hurricane season generates 26.7 ACE. This year through August 26th? A measly 2.9 ACE.

Is it because the answer is none?  Because until the rest of the world (China) gets serious about it we're only spinning our wheels.

I don't think the answer is exactly none, but it would be tiny, unmeasurable, maybe a tenth of a degree, maybe, probably less than that versus no bill.

It should be readily calculable using a standard model.  The Bill will cause a drop in CO2 production of X gigatons and that means 0.03°C less warming.

The IRA is predicted to reduce emissions by 40%. It’s not that simple. - The Washington Post

Depending on how you read that 40 percent estimate, it could be a bit misleading. This is a case of where the models may be correct, but not widely appreciated. The bill is expected to cut emissions by 40 percent compared with 2005 levels — not compared to current U.S. emissions. That’s because emissions have already decreased substantially since 2005. Between 2005 and 2020, CO2 emissions dropped by about 21 percent, thanks largely to a shift from heavily polluting coal to less-polluting natural gas. (The COVID-19 pandemic also caused a dramatic decline in emissions, as millions of cars and planes ground to a halt virtually overnight.)

Over the next eight years, emissions are expected to continue to trend slowly downward, thanks to cheap solar and wind power and a gradual shift to electric vehicles.
Indeed, according to the same three modeling groups, by 2030, emissions are expected to decline by 24 to 32 percent — even without the Inflation Reduction Act.
That doesn’t mean that the bill is without impact, of course. While it might not be as dramatic a shift as it seems initially, in a world in which every extra ton of CO2 not emitted into the atmosphere can help can help curb global warming, an additional 10 to 15 percent reduction in emissions will help to avert serious environmental damage.

Even if we stop all emissions tomorrow the warming effect would still proceed for a long time because the correlation between GHG emissions and warming is not immediate.  We need to not only reduce emissions we need to start pulling CO2 and other GHG out of the atmosphere.  Obviously removing CO2 from the atmosphere is not really possible with current technology so I don't know what can be done to help this situation.

CO2 capture is working directly against entropy ina huge way.  The only way to overcome entropy of course is with energy.  This is something we can't get around at all, ever.

But sure, with enough energy we could remove CO2 from the air.

The US generates about 5 gigatons of CO2 per year.  This bill may reduce that by 10-15%, perhaps.  Current trends had us on a path to reduce it by 25-30% anyway.  If we generously say this bill means 1 gigaton less CO2 per year will be generated, well, a very simplistic notion is 500 gigatons = 1.5°C, some one Gt per year would have a vainishingly tiny impact.

 In 2019, the year before the COVID pandemic depressed the global economy, the world discharged about 42 gigatons of CO2—similar to the 2018 level and to what is happening in 2021. According to the midrange scenario in the Intergovernmental Panel on Climate Change’s comprehensive report released in August, “Climate Change 2021: The Physical Science Basis,” another 500 gigatons of CO2 emissions will raise global temperature by 1.5 degrees. Nations have about 11 more years at current emissions rates—2032—before exhausting the budget.

 As of July 30, the U.N. report says, 113 of the 191 nations that signed the Paris Accord had made some level of commitment to reduce emissions. Under the latest promises, global emissions by 2030 would actually be 5.0 percent higher than in 2019—not lower—in the midrange scenario the IPCC uses. The report notes that emissions from the nations that have issued revised goals since 2015, as a group, would indeed be lower in 2030 compared with 2019, so the net increase worldwide would come from the countries that have not improved their original commitments and countries that have never committed.

Therein lies the rub right?

support?

ya mean demand or consumption?

or support by politicians to try to burn the planet?
