If COVID19 was the climate crisis in fast-forward, I guess we're somewhere around mid-February 2020, in climate terms?

It still hasn't sunk in, but it is starting to sink in, and it doesn't feel good at all.

September 2023 beat the previous record for that month by 0.5C, the largest jump in temperature ever seen. September was about 1.8C warmer than pre-industrial levels. Datasets from European and Japanese scientists confirm the leap. The heat is the result of the continuing high levels of carbon dioxide emissions combined with a rapid flip of the planet’s biggest natural climate phenomenon, El Niño. The previous three years saw La Niña conditions in the Pacific Ocean, which lowers global temperature by a few tenths of a degree as more heat is stored in the ocean.

Unexpected decline in the ocean carbon sink under record-high sea surface temperatures in 2023

Fun fact: if ocean regions outgass more CO2 you get a self heating effect of more downward longwave radiation - happens e.g. over the Indo-Pacific warm pool the warmest water mass on Earth...
Unexpected decline in the ocean carbon sink under record-high sea surface temperatures in 2023 In 2023, sea surface temperatures (SSTs) reached record highs, partly due to a strong El Niño. Based on historical responses to elevated global mean SSTs, oceanic CO2 uptake in 2023 should have increased (−0.11 ± 0.04 PgC yr−1), driven by reduced outgassing in the tropical Pacific Ocean. However, using observation-based estimates of ocean CO2 fugacity, we show here that the global non-polar ocean absorbed about 10% less CO2 than expected (+0.17 ± 0.12 PgC yr−1). This weakening was caused by the anomalous outgassing of CO2 in the subtropical and subpolar regions, especially in the Northern Hemisphere, driven primarily by elevated SSTs reducing the solubility of CO2. In most regions, this SST-induced outgassing was mitigated by the depletion of dissolved inorganic carbon in the surface mixed layer. Such negative feedbacks caused an overall muted response of the ocean carbon sink to the record-high SSTs, but this resilience may not persist under long-term warming or more severe SST extremes.

I'm never playing #Peak again. :blobfoxonepunch:

The people were great, their company was great, and good fuckin bless easy mode.

HOLY HELL, IT'S A TIME SINK THOUGH. #IF-THE-PACIFIC-OCEAN-WAS-A-SINK #THAT-IS-THE-TIME-SINK-OF-A-RUN-OF-PEAK #PEAK-THE-GAME #I'M-NEVER-DOING-IT-AGAIN #BECAUSE[...]
