Through the heatwave haze, the hypocrisy of Australia’s fossil fuel policy shines bright

"The heatwave that blanketed much of Australia in early January was five times more likely to occur now than before human-caused global heating changed the climate." World Weather Attribution

"The focus in 2026 is increasingly likely to turn to the nation’s huge fossil fuel exports, an area where the government – which declares it is committed to trying to limit global heating to just 1.5C, a goal rapidly fading from view – remains blatantly hypocritical...Thermal coal expansions still get the greenlight."

Through the heatwave haze, the hypocrisy of Australia’s fossil fuel policy shines bright

The heatwave in Melbourne and Adelaide this week is likely to become the norm. We should prepare now

Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the #HabitableZone: https://arxiv.org/abs/2507.09343 -> A diverse cast of rocky worlds around a small star revealed by Montreal astronomers: https://nouvelles.umontreal.ca/en/article/2025/07/22/a-udem-team-confirms-a-fifth-potentially-habitable-planet-around-l-98-59-a-red-dwarf-35-l/
Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone

The L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83-day non-transiting planet confirmed in 2021 using ESPRESSO. The planets exhibit a diverse range of sizes (0.8-1.6 R$_{\oplus}$), masses (0.5-3 M$_{\oplus}$), and likely compositions (Earth-like to possibly water-rich), prompting atmospheric characterization studies with HST and JWST. Here, we analyze 16 new TESS sectors and improve radial velocity (RV) precision of archival ESPRESSO and HARPS data using a line-by-line framework, enabling stellar activity detrending via a novel differential temperature indicator. We refine the radii of L 98-59 b, c, and d to 0.837 $\pm$ 0.019 R$_{\oplus}$, 1.329 $\pm$ 0.029 R$_{\oplus}$, 1.627 $\pm$ 0.041 R$_{\oplus}$, respectively. Combining RVs with transit timing variations (TTV) of L 98-59 c and d from TESS and JWST provides unprecedented constraints on the masses and eccentricities of the planets. We report updated masses of 0.46 $\pm$ 0.11 M$_{\oplus}$ for b, 2.00 $\pm$ 0.13 M$_{\oplus}$ for c, and 1.64 $\pm$ 0.07 M$_{\oplus}$ for d, and a minimum mass of 2.82 $\pm$ 0.19 M$_{\oplus}$ for e. We additionally confirm L 98-59\,f, a non-transiting super-Earth with a minimal mass of 2.80 $\pm$ 0.30 M$_{\oplus}$ on a 23.06-day orbit inside the Habitable Zone. The TTVs of L 98-59 c and d (<3 min, $P_{\rm TTV} = 396$ days) constrain the eccentricities of all planets to near-circular orbits ($e \lesssim 0.04$). An internal structure analysis of the transiting planets reveals increasing water-mass fractions ($f_{\rm H_{2}O}$) with orbital distance, reaching $f_{\rm H_{2}O} \approx 0.16$ for L 98-59\ d. We predict eccentricity-induced tidal heating in L 98-59 b with heat fluxes comparable to those of Io, potentially driving volcanic activity.

The local meteorologist referred to today's weather as the "Goldilocks Zone." I described that as "#HabitableZone" on my #ClimateChangeWeatherWheel -- but I like the idea of #GoldilocksZone -- not too hot, not too cold. Treasuring the days where we're in the G-Zone.

A #Galactic Habitable Zone excludes stars too close to the galactic center. Our Sun is a nice distance away from the galactic center, about 28,000 light years. Keeping out of the way of the Galaxy’s spiral arms is another requirement of the Galactic #HabitableZone https://astrobiology.nasa.gov/news/galactic-habitable-zones/
