| Video Discription | As I said many moons ago, Earth is losing the ability to provide for and support us and all the plants and animals. It is not rapidly dying, but it is actively being killed by us and the weapon of choice that we use is our fossil fuel combustion. I chat about a brand spanking new peer reviewed scientific paper on Ecological Tipping Points. Basically, we have been modelling dynamic systems incorrectly for years, and we do not recognize the reality that many of our ecological and physical systems are much closer to abrupt tipping point thresholds than we can imagine. Most of our models to-date examine incremental change in one primary driver that increases and eventually reaches a threshold whereby the system either undergoes a “flickering” between the existing and new state, or a critical slowing down of frequency (with an increase in amplitude of fluctuation) and then flips (tips) into a new system state. In reality, systems are more complex than this, and we need to model: 1) changes in primary driver 2) changes in secondary driver 3) changes in tertiary driver 4) addition of stochastic (random) or uncoupled noise 5) addition of coupled noise When we include all of these multiple forcings and two types of noise into our simulations, we find that the system tipping (crossing a breakpoint or threshold of no return) occurs much sooner, in fact occurs substantially sooner, or closer to today by between 38% and 81%. Although the four different systems examined in this paper represent a cross-section of all systems, the results are likely variously applicable to Earth systems like Arctic Sea Ice collapse to a Blue Ocean event, collapse of Amazon Rainforest to a grassland or savannah state, loss of Boreal Forests, Ocean Acidification, Loss of Arctic Permafrost, loss of Greenland Ice Sheets, loss of Antarctica Ice sheets, and Shutdown of AMOC and PMOC (Pacific Meridional Overturning Circulation), as well as Biodiversity Collapse. Please donate to http://PaulBeckwith.net to support my research and videos as I educate people and caution people on our ongoing abrupt climate system change. Live long and prosper, or at least be in the know. Sincerely, Paul, Shackey, Newton, … I3gLZZHu2_I |
