Recent data and scientific analysis have highlighted a concerning trend in global climate conditions, with February 2024 recording remarkably warm temperatures near the North Pole. Additionally, 80% of the Great Barrier Reef has experienced severe bleaching events in recent years, with predictions for widespread coral mortality due to anthropogenic heating. Sea surface temperatures (SSTs) have been exceptionally high over the past year, aligning with the extremes expected in a scenario of rising CO2 emissions. This has culminated in record global ocean warmth lasting over 365 days, a phenomenon that scientists are struggling to fully explain. The magnitude of temperature anomalies in the Arctic, the prolonged ocean heat records, and the fact that ~93% of the world's oceans experienced a marine heatwave in 2023 underscore the urgent need for understanding and addressing the impacts of climate change. The divergence between expected and observed annual mean temperatures in 2023 remains about 0.2 °C, revealing an unprecedented knowledge gap.
Global temperatures are continuing to rise, resulting in dangerous weather events which have devastating impacts on our communities. It's clear we need to take decisive, bold action to reverse the effects of the #climatecrisis before it's too late. https://t.co/G7bQwX6gKf
We must listen to our planet 🌎 The world is warming up due to climate change, damaging communities and habitats across the world with far-reaching and irreparable impacts. https://t.co/S8BhjweoOc

Temperature anomalies over the last month (left), 3 months (center), and 12 months (right) in the Arctic... check out the magnitude of those departures north of Svalbard and Novaya Zemlya! Data from @CopernicusECMWF ERA5 reanalysis at https://t.co/e7aUafgc7S https://t.co/tRXnLeCxTH
Scientists Alarmed by Spike in Ocean Temperatures https://t.co/jcfPCQqt9J
Relative to the (CMIP6) multimodel climate simulation ensemble, 2016 temperatures were more of an outlier than 2023 (i.e., they come closer to the upper 95th percentile of the simulations) (h/t/ @hausfath): https://t.co/YztvOsApgA
🚨We've now seen over a year of record-high ocean temperatures — wreaking havoc on marine life & creating dangerous climate conditions around the globe. Mother Earth is blaring the alarm on the climate crisis every single day. When will Republicans listen?https://t.co/XZGYoh4cwz
~93% of the World's oceans experienced a marine heatwave in 2023. Orange = Strong and Darkest color = extreme. That is up from ~55% of oceans experiencing a marine heatwave in the 1980s. That figure is the next figure in this thread 1/ https://t.co/hbPpJwcpi2
"Even after taking all plausible explanations into account, the divergence between expected and observed annual mean temperatures in 2023 remains about 0.2 °C ... the 2023 temperature anomaly has come out of the blue, revealing an unprecedented knowledge gap" https://t.co/x4zZ3mn8NT
Extremely important read. tl;dr: as I've been saying for a year, the scientific community can NOT explain the crazy heating that started last March. This opens much wider that troubling door to the possibility of much faster than expected heating going forward. https://t.co/pgQwQrokh5
I have a commentary in Nature about our disquieting inability to explain why 2023 was so warm. https://t.co/8qDRc3IHSk
Current Climate: Big Risks As Oceans Overheat https://t.co/UP4LyqFYQ1

My prediction - billions of corals will die on the #GreatBarrierReef this year due to anthropogenic heating. Because accumulated heat exposure this summer is the highest on record, and for the 1st time it’s affecting all regions of the Reef. https://t.co/jyDnetOH8i
Record global ocean warmth has just surpassed the 1-year mark, and scientists don't have complete explanations for it. @BMcNoldy pointed to "The absurdly-large margins by which the records have been broken" as esp. noteworthy. https://t.co/SlI1gma1St https://t.co/dGRAeoAmgK
Sea surface temperatures have been exceptionally high over the past year. Unfortunately this is in-line with the extremes that we expect to see in a world where CO2 emissions continue to rise. This graph shows observed SSTs compared with the latest generation climate models: https://t.co/6vcq6Visb9
80% of reefs throughout the #GreaBarrierReef bleached severely at least once in 2016, 2017 & 2020. That cumulative number will increase this summer. (Category 4 bleaching in red means >60% of corals were bleached) https://t.co/VjY0hjqdH1
