Potential Perturbation of the Ionosphere by Megaconstellations and Corresponding Artificial Re-entry Plasma Dust (2023) (arxiv.org)

500,000 to 1 million satellites are expected in the next decades, primarily to build internet constellations called megaconstellations. These megaconstellations are disposable and will constantly re-enter and be replaced, hence creating a layer of conductive particulate. Here it will be shown that the mass of the conductive...

Last Glacial Maximum pattern effects reduce climate sensitivity estimates (www.science.org)

Abstract Here, we show that the Last Glacial Maximum (LGM) provides a stronger constraint on equilibrium climate sensitivity (ECS), the global warming from increasing greenhouse gases, after accounting for temperature patterns. Feedbacks governing ECS depend on spatial patterns of surface temperature (“pattern effects”);...

2025: A Civilizational Tipping Point (thehonestsorcerer.substack.com)

The main message here is that it looks increasingly certain that we will run out of resources sooner than the coming deterioration of the climate could put an end to our lifestyle. (And that’s quite a feat, knowing how a growing Earth energy imbalance has accelerated warming recently…) The model also assigns a not so distant...

Is the Atlantic Overturning Circulation Approaching a Tipping Point? (tos.org)

The Atlantic Meridional Overturning Circulation has a major impact on climate, not just in the northern Atlantic but globally. Paleoclimatic data show it has been unstable in the past, leading to some of the most dramatic and abrupt climate shifts known. These instabilities are due to two different types of tipping points, one...
