My spouse and world sailing partner had a piece in Nature today about tackling sexism in Australian science. Tackling pervasive sexism in Australian science requires money, leadership and time nature.com/articles/d4158…

Major changes to NEPA in the budget deal, and not just for energy projects. Some of it codifies existing practice, some of it adds adds time limits and page limits, and possible new NEPA exemptions. Still wrapping my head around this. Starts on p 71. docs.house.gov/billsthisweek/…

This is such a great challenge. Decarbonising the IPCC requires dealing with all the thorny issues: "hard-to-abate", carbon dioxide removal, offsets, fairness, etc. And who is better placed to demonstrate what is possible than the IPCC itself! nature.com/articles/d4158…

3) paying SS benefits (which are still secured by US debt in trust fund). Other appropriations are harder to characterize as “debt” of US. /f

Frankly, I rate the debt ceiling bypass options b4 a literalist court as follows: 1) $ trillion coin 2) later budget legislation implicitly repeals earlier debt limit 3) 14th Am “debt shall not be questioned.” 1/

Problem with the 14th Am approach is that it literally prioritizes 1) paying bond principle when due by issuing new debt (which does not actually increase total US debt 2) arguably, paying interest on bonds when due, and 2/

Gotta admit I am a little disappointed that Robert F Kennedy Jr’s campaign page does not even mention climate change as an issue. Clean it Up | Kennedy24 kennedy24.com/environment

@Peter_Strachan @si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens Read my link. It is not per person per year. Even the highest emitters on the planet (like the US) are “only” about 20 tons per year. A newborn baby doesn’t start out emitting 3x as much and by the time they are 30 it’s not likely even 20 ton lifestyles will be sustainable.

@kcoplan @si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens It's per person, per year. If you recycle, there is a saving per person until they die. If you have one less child, the legacy of that decision and its saving is ongoing forever and can be calculated per year for the person that makes that choice.

@Peter_Strachan @si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens It’s not correct to say 58 tons per year when there is no year in which 58 more tons of CO2 will be emitted because you had one more child.

@kcoplan @si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens Yes, it's the legacy saving over time. That is a totally correct way to analyse actions taken in your lifetime, like deciding to be child-free, compared with being vegan or riding a bicycle and recycling stuff in your lifetime.

@DaddyD0dd also, that “58 tons per year” carbon impact of one child is total bs. There is no reason to expect your child to have a bigger annual carbon footprint than your own. Explained it here: livesustainablynow.com/2017/07/14/no-…

@Peter_Strachan @si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens Sorry, that “57 tons per year” for one child is total bs. Explained it here: livesustainablynow.com/2017/07/14/no-…. The underlying article takes your child’s future descendants impacts over several centuries and divides by approximate forty years for no particular reason.

@si_opus_sit @gteasts @JaneoOakley @ABCaustralia @Greens All technical advances that can be achieved by tinkering around with a circular economy, recycling, reusing, riding a bike or going vegan are overwhelmed by the impact of ongoing population growth The most effective way to reduce your carbon footprint is to have one less child.

fairly modest, especially when you include the impacts of a hotel stay. But I get to have a travel adventure, and keep the rhetorical power of the #flyingless argument for taking climate seriously in your own life. /F

and a bus connection to Canberra. I am on the bus now, due to arrive in Canberra 3:40 this afternoon (it’s Thursday here). The combined price of the 48 hour odyssey, including an inexpensive hotel, is just a little more than a direct flight. The CI2 savings are 7/

Taking #flyingless to a new extreme! Having sailed a boat halfway round the world, from NY to Hobart, TAS, I needed to get to Canberra to attend a gala dinner for US Fulbright scholars. (My spouse, the indomitable @robinbell is a Fulbright Distinguished Chair at CSIRO) 1/
