Oceans, oceans, oceans. You thought the atmosphere was complex? Well, just take a look at the oceans. Oddly shaped features with disturbing cycles and conveyor belt currents. Home of the octopus, the blue whale and a Mariana Trench full of … Continue reading →
In part 16 of our temperature trend series we take a better look at one of the main reasons almost everyone still underestimates climate urgency: ‘Thermal inertia’ of the climate system – a delay between the moment of emissions of … Continue reading →
Here at Bitsofscience.org we’ve written quite extensively on why a direct shutdown of the Gulf Stream is unlikely – and that the collapse scenario featured in that one movie we only ever saw the trailer of probably did not even … Continue reading →
Ten years after Katrina* the world is on the brink of a whole new cluster of climatic disasters, including wide-spread coral bleaching, Pacific atol floods, possibly another devasting Brazil drought and another record-breaking hot year, following from the currently developing … Continue reading →
If we take another look at the IRI ensemble forecast for El Niño some members show a clear and speedy rise in East Pacific tropical ocean temperatures. Before we conclude ‘El Niño ahead’ during northern hemisphere summer and autumn let’s … Continue reading →
Judging by new ocean sediment measurements and climate model runs the Atlantic Meridional Overturning Circulation (AMOC) was ‘at least as strong’ during the last ice age’s Last Glacial Maximum as it is today.
“The Southern Ocean is a large window by which the atmosphere connects to the interior of the ocean below” – Jean-Baptiste Sallée from British Antarctic Survey, lead author of new publication in the August edition of Nature Geoscience.
Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science. The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings in the El Niño-Southern Oscillation (ENSO). “As humans continue to pump greenhouse gases into the atmosphere, the climate is once again on the threshold of a new regime, with dire consequences for reef ecosystems unless we get control of climate change,” said coauthor Richard Aronson, a biology professor at Florida Institute of Technology.
