done a bit of sprucing to the football nook, finally put my scarves up and put up the new shirts I got specifically for decoration (bc they don't fit me lol)
I need to acquire a ladder or a tall friend to fill in the space higher up #fedifc
Why isn't it possible to simply agree that we must do 2 things to mitigate #climate change: 1) Eliminate nearly all anthropogenic GHG emissions and 2) Increase the rate of CO2 sequestration?
And then we can focus on the merits/demerits of actions in both spaces? We are not facing exclusive options here, after all. (1/2)
Could nature itself hold the solution to climate change?

#ScribesAndMakers June 20: How difficult is it for you to receive criticism of your creative work?
I usually love receiving feedback on my work. Of course it can hurt if it was a work that I was emotionally invested in and people don't like it. But most often, the criticism is there for a reason and I can decide I either don't care, I don't agree, or I see their point …

Abstract: Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line maps for a large sample (72) of normal, low-redshift galaxies spanning three orders of magnitude in stellar mass and four orders in star formation rate (SFR). We find a steep turnover occurring at $(1-2) R_e$ in the H$\alpha$, [O {\small II}], and [O {\small III}] line emission radial profiles. Beyond this radius, the slope of the line emission radial profiles becomes shallower as the SFR of the central galaxy decreases, which might reflect the strength of the feedback processes. The line emission fluxes at large radius ($(5-10) R_e$ or $\sim (0.1-0.25)r_{\rm vir}$) correlate with the galaxy's SFR, but not with its stellar mass. These findings suggest that ionizing photons escaping from star-forming regions in the central galaxy account for the observed emission line fluxes from the inner CGM, with escape fractions inferred from the [O {\small III}] and [O {\small II}] ratio. Different state-of-the-art theoretical models do not agree on the predicted dependence of cool gas on the SFR of the central galaxies, highlighting the importance of CGM emission line measurements to distinguish between different subgrid models for star formation and feedback processes.
