Scientists are warning of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current, due to weakening under a warming climate. This collapse could have significant global weather implications, with the North Atlantic Oscillation (NAO) also unable to mitigate an ongoing Atlantic heatwave in 2024. Additionally, a new study suggests that natural variability, such as a 1940s El Niño event, initiated the retreat of the Thwaites 'Doomsday Glacier.' Heat stress is increasing on the Great Barrier Reef, with coral bleaching expected to peak soon.
In the North Atlantic, water temperatures are running 3 months ahead of schedule, at May-level temperatures. In the main hurricane corridor, sea temperatures are closer to July levels. — Atlantic heat this early is a bad sign for hurricanes, corals https://t.co/YO3zj2djwn
New discovery suggests significant glacial retreat in West Antarctica began in 1940s @PNASNews https://t.co/CmRHi87M35
Another mass coral bleaching event is likely to unfold along the #GreatBarrierReef in coming weeks. Sea surface temperature anomalies are +1.3-1.9C, and accumulated heat stress (Degree Heating Weeks, DHW) is already well above the bleaching threshold, especially in the south. https://t.co/krPFdnJmSS
The 'Doomsday Glacier' is rapidly melting. Scientists now have evidence for when it started and why https://t.co/a3x3e1QEnt
Heat stress (red) is still rising along the #GreatBarrierReef, & is much higher than last summer. We’re approaching the optimal timing for aerial surveys in March. If you go too early, coral bleaching hasn’t peaked. Too late, many of the bleached corals will already be dead. https://t.co/Uxig9waznn
New research warns that the Atlantic Meridional Overturning Circulation, or AMOC, is weakening under a warming climate, and could potentially suffer a dangerous and abrupt collapse with worldwide consequences. Read more: https://t.co/zjHdWL8m3K https://t.co/7tZ6rbso5Q
Scientists are sounding the alarm that a crucial component of the planet’s climate system is in gradual decline and could one day reach a tipping point that would radically alter global weather patterns. Read more: https://t.co/zjHdWL8m3K https://t.co/HgA9ELG8SS
'Doomsday glacier' climate narrative wrecked by new study. Natural variability (a 1940s El Niño event) kicked off the ongoing Thwaites (so-called 'Doomsday') glacier retreat: "The glacier retreat in the Amundsen Sea was initiated by natural climate variability in the 1940s .… https://t.co/ziAxHvTuXh
New research warns of a possible collapse of Atlantic Ocean currents, which could fundamentally alter global weather patterns. “This is bad news for the climate system and humanity,” the study says. More here: https://t.co/nzxrh2mFFP
We've got an MJO event starting to kick up in the Indian Ocean, as seen by widespread convection in its western half. This will destructively interfere with El Nino soon and hasten its oncoming demise https://t.co/DYDj15ucgC
Excellent post from @AndyHazelton with plots from @cyclonicwx @NWSCPC. The North Atlantic Oscillation (NAO) is a primary driver of deep tropical MDR ocean temps but unfortunately the ups in the NAO (+NAO) haven't been enough to dampen the ongoing Atlantic heatwave so far in 2024. https://t.co/MWJPMKarUy
