If we view the future through the lens of plausible IPCC scenarios (AR5 & SSP consistent with 2005-2020 reality & 2020-2040 near-term projections), the below shows fossil fuel CO2 emissions without application of an negative emissions technologies
One comment we have received on this analysis is that the envelope of emissions in 2100 from plausible scenarios may not actually reflect all plausible outcomes
We agree!
That is an argument (which we make) for updating IPCC scenarios & not continuing to use outdated scenarios
One note: Sad that this has to be said but there is an academic tweeting falsely that we have accused others of "research misconduct"
I won't dignify it with a link, such smears are gross and unprofessional but all too common in this field
Play the ball not the person⚽️

Now bear with me... imagine a 19th/20th century alternative history with the western world female dominated & our female leaders created a modern Olympics centered on exalting female athleticism - like in gymnastics and synchronized swimming (as above), with men cheering along...
How we talk about disasters has changed dramatically (since ~2006)
The IPCC definition of "climate change" as a detectable change in the statistics of weather (and outcome metric) has been increasingly rejected in favor of "climate change" defined as a causal actor that changes weather
These definitions are 100% incompatible
17 years ago I wrote about how the different definitions of "climate change" used by the FCCC and IPCC was problematic for connecting science and policy sciencepolicy.colorado.edu/admin/publicat…
The increasing use of "climate" (or "climate change") as a causal actor adds to this dissonance
1⃣
First, improve the process for the WHO’s declaration of a public health emergency.
2⃣
Second, countries should agree on common standards for data collection and dissemination during a pandemic, to inform responses and enable relevant research to be undertaken.
3⃣
Third, nations should agree to establish international standards for the recommendation of vaccine and drug approval in a pandemic.
4⃣
Fourth, nations should agree on procedures for investigations of pandemic origins.
The fact that COVID-19 first broke out in a city housing one of the world's few high-level labs engaged in bat coronavirus research means a lab leak necessarily must be on the list of possible origins until it's conclusively refuted, regardless what theoretical arguments are made
The CDC current says that 15% to 70% of COVID-19 cases may be asymptomatic, with a best guess of 30% (deets below)
So if there was a lab leak, there is a meaningful chance that the leak would have been unknown to the lab or the individual(s) who may have been a vector
To hit a 2% of GDP target for US federal R&D spending (i.e., same as peak of space race) would require annual $ increases of:
30%-->2026
18%-->2030
13%-->2035
10%-->2040
US federal R&D $ has been more or less constant as a % of domestic discretionary spending for >40 years
Data @aaas@MattHourihan
Meaningful increases in R&D $ > increases in domestic disc $ would represent the most significant change in US R&D OVERALL budget policy in a half century
So key to watch is if federal spending increases dramatically overall, cause R&D ain't gonna eat someone else's lunch
