Climate Crisis Round Up Published 6/15/26AM

Some items are a bit older as I've been swamped.

Even moderate levels of warming can unleash extreme climate damage

Climate models reveal that certain 3.6°F warming scenarios can produce more severe impacts than average projections at higher temperatures.

Arctic ocean passes 'irreversible' chemical tipping point - Oceanographic

New data shows that decades of ice loss have altered Arctic ocean chemistry, triggering an irreversible disruption to Arctic foodchain

Antarctic Peninsula sees record high June temperatures

Temperatures in the Antarctic Peninsula have reached a record-breaking high of 15.4C for June, and ice is melting at abnormal rates during t

Study shows thawing permafrost releases much more greenhouse gas than expected

Thawing permafrost emissions could accelerate climate change as Arctic soils become 25x to 100x more permeable, releasing much more gas.

Reducing air pollution has triggered something even worse for the planet that scientists did not predict

Cleaner air is making marine clouds dimmer and oceans warmer, revealing a climate trade-off called the "clean air paradox."

Atlantic current system could be weakening faster than expected

The Atlantic current system, or more formally the Atlantic Meridional Overturning Circulation (AMOC), is more likely to weaken than previous

This Growing El Niño Could Irreversibly Alter Earth’s Climate, Experts Warn

Research has shown that severe El Niño events can have lasting effects on Earth’s systems—potentially locking the global climate into a warm

Study finds sea levels are higher than we thought, placing millions more at risk

Climate change's rising seas may threaten tens of millions more people than scientists and government planners originally thought because of

Hurricanes are slowing down - and dumping far more rain than before

Warming oceans are making hurricanes wetter and slower, increasing rainfall intensity and flood risks across the North Atlantic.

Climate change in the US impacts each state differently

Warming is occurring across most U.S. states, though the pace and type of temperature changes vary widely from region to region.

The American scientific enterprise, the source of so much wealth and national prestige, is being unravelled before our eyes—research grants are being cut off, satellites disconnected, reports cooked up to meet the needs of particular industries and ideologies. It is as sad as any of the other dismal effects of the past election. But the scientific method will not, perhaps, go quietly. With hundreds of years of patient work behind it, with some educational institutions willing to protect their scientists, and with researchers hard at work in less-benighted nations, the human desire to know and to understand will continue to produce results. Many of those findings will be contrary to the interests of the blowhards who, at least temporarily, control our nation, and so they may be suppressed for the moment. But whether or not they are heeded, in the end, the truth will out. If it’s not in the form of enlightened policy, it will be in the form of pandemics and wildfires, of untreated disease and rising sea level. Because life really is like this.

#1829: the last glacial maximum, when much of the world was frozen and thus lots of the water was frozen in ice sheets, was about 22 thousand years ago. the ice extended from the top of Greenland to what is now the continental US - the Great Lakes were thought to be formed by the retreat of the Wisconsin glacier about 10-12kyBP. the sheet covering North America in up to 3.2km of ice is called the Laurentide ice sheet, which was so massive (its area is measured in MILLIONS of square miles) that it pretty much dictated the global climate.

since the last glacial maximum, the global sea level has risen drastically. i've seen quite different numbers for exactly how much, but roughly 110-130m in that 22 thousand years. even in the last 5ky there's been a reasonably large rise of about 5m. this has wildly changed the coastline - i was aware of Doggerland, the big bit of land between what's now England, France and Germany that disappeared about 10-8kyBP, but now i'm reading about it in the context of the Floridan peninsula, which has more than halved in area since the last glacial maximum.

'MRI' scan reveals spectacular ice age landscapes beneath the North Sea

Spectacular ice age landscapes beneath the North Sea have been discovered using 3D seismic reflection technology. Similar to MRI (magnetic resonance imaging) the images reveal in unprecedented detail huge seafloor channels—each one 10 times wider than the River Thames.

“Spectacular ice age landscapes beneath the North Sea have been discovered using 3D seismic reflection technology. Similar to MRI (magnetic resonance imaging) the images reveal in unprecedented detail huge seafloor channels—each one 10 times wider than the River Thames.

For the first time an international team of scientists can show previously undetectable landscapes that formed beneath the vast ice sheets that covered much of the UK and Western Europe thousands to millions of years ago. These ancient structures provide clues to how ice sheets react to a warming climate.

So called tunnel valleys, buried hundreds of meters beneath the seafloor in the North Sea are remnants of huge rivers that were the 'plumbing system' of the ancient ice sheets as they melted in response to rising air temperatures.“

Speed at which world’s glaciers are melting has doubled in 20 years

Glacier melt contributing more to sea-level rise than loss of Greenland and Antarctic ice sheets, say experts
