In 2023, the global mean temperature soared to almost 1.5K above pre-industrial level, surpassing previous record by about 0.17K. Previous best-guess estimates of known drivers including anthropogenic warming and El Niño onset fall short 0.2K in explaining rise. Utilizing satellite reanalysis data, we identify a record-low planetary albedo as primary factor bridging this gap. The decline is apparently caused largely reduced low-cloud cover northern mid-latitudes tropics, continuation multi-annual trend. Further exploring trend understanding how much it due internal variability, aerosol concentrations, or possibly emerging feedback will be crucial for assessing current expected future warming.

Abstract. Global-mean surface temperature rapidly increased 0.29 ± 0.04 K from 2022 to 2023. Such a large interannual global warming spike is not unprecedented in the observational record, with previous instance occurring 1976–1977. However, why such spikes occur unknown, and rapid of 2023 has led concerns that it could have been externally driven. Here we show climate models are subject only internal variability can generate spikes, but they an uncommon occurrence (p = 1.6 % 0.1 %). when prolonged La Niña immediately precedes El Niño simulations, as occurred nature 1976–1977 2022–2023, become much more common 10.3 0.4 Furthermore, find nearly all simulated 88.5 0.3 %) associated year.

The 2023 saw strong but surprisingly active NA WNP TC activities. Here, we present that these unprecedented deviations were driven by record-warm NA, record-breaking negative phase of Meridional Mode (PMM), background global warming.

We investigated ecophysiological responses two common hard corals ( Acropora sp. Pocillopora verruco sa) from Central Red Sea under ambient (26 °C) elevated seawater temperatures (32 °C), with without hydrogen addition ~ 150 µ M H 2 ) over 48 h. Our results showed that at 32 °C addition, P. verrucosa exhibited high temperature tolerance, whereas significant reductions in photosynthetic efficiency maximum electron transport rate compared condition °C).
