[1] ['This Content Is Not Subject To Review Daily Kos Staff Prior To Publication.'] Date: 2024-06-21 You have got to love this, we have nearly fucked up the biosphere now we want to play with it, even if we do not know quite what the consequences are. What happens if we change this, hmm, let us give it a go, oops sorry Italy. Who Knew? The authors of the study said the findings were “scary” because the world has few or no regulations in place to prevent regional applications of the technique, marine cloud brightening, which involves spraying reflective aerosols (usually in the form of sea salt or sea spray) into stratocumulus clouds over the ocean to reflect more solar radiation back into space. From the Study Diminished efficacy of regional marine cloud brightening in a warmer world Marine cloud brightening (MCB) is a geoengineering proposal to cool atmospheric temperatures and reduce climate change impacts. As large-scale approaches to stabilize global mean temperatures pose governance challenges, regional interventions may be more attractive near term. Here we investigate the efficacy of regional MCB in the North Pacific to mitigate extreme heat in the Western United States. Under present-day conditions, we find MCB in the remote mid-latitudes or proximate subtropics reduces the relative risk of dangerous summer heat exposure by 55% and 16%, respectively. However, the same interventions under mid-century warming minimally reduce or even increase heat stress in the Western United States and across the world. This loss of efficacy may arise from a state-dependent response of the Atlantic Meridional Overturning Circulation to both anthropogenic warming and regional MCB. Our result demonstrates a risk in assuming that interventions effective under certain conditions will remain effective as the climate continues to change. The point is; stop tinkering with things that you cannot predict, especially when someone else is doing something else simultaneously. Humanity when faced with a big red button with the plate “Do not push” attached, everyone knows what is eventually going to happen, adults in the room be damned. The more desperate we get, the more alluring that big red button becomes. Why do we keep ignoring the simpler steps, one word, politics? The search for the do-nothing, cost-nothing miracle cure goes on! Maybe if we look away it’ll be OK? Hmm You do know, we are paying attention? The link goes to dept of Sociology, University of Oxford [published yesterday] The biggest ever standalone public opinion survey on climate change, the Peoples’ Climate Vote 2024, shows 80% – or four out of five - people globally want their governments to take stronger action to tackle the climate crisis. Even more - 86% - want to see their countries set aside geopolitical differences and work together on climate change. The Peoples’ Climate Vote 2024 is the second edition of the global survey carried out by the UN Development Programme (UNDP) and the University of Oxford's Department of Sociology. More than 73,000 people, speaking 87 different languages across 77 countries, were asked 15 questions on climate change for the survey. The questions were designed to help understand how people are experiencing the day-to-day impacts of climate change and how they want world leaders to respond. Polling was conducted by international polling firm, GeoPoll, via randomised mobile telephone calling. The 77 countries polled represent 87% of the global population.
