Hi Halc, here we go again! My interpretation, which could well be wrong, is that a lot of the ground work for relativity was done by Lorentz, Fitzgerald, Poincare and others and that Einstein had the vision to knit it all together in SR. I certainly was not considering LET(aether! God forbid!). I am somewhat confused by your statement that light emitted by a moving body does not travel at c: suppose an observer measures a body passing by at 0.5c and then this body emits a pulse of light- surely in both the frame of the observer and the frame of the emitter the speed of said light pulse will be c? Impinge is a word I have often seen used in this context similar to collide, strike or we could use the biblical term "smite". One final request, Halc, refresh my ageing brain as to the conflict between Maxwell and Newtonian mechanics.
" Here, we provide spatial and temporal observation-based analyses of the role of natural and anthropogenic factors, using state-of-the-art time series methods. We show that the risk from extreme temperature and rainfall events has severely increased for most regions worldwide. In some areas the probabilities of occurrence of extreme temperatures and precipitation have increased at least fivefold and twofold, respectively.
Anthropogenic forcing has been the main driver of such increases and its effects amplify those of natural forcing. We also identify risk hotspots defined as regions for which increased risk of extreme events and high exposure in terms of either high Gross Domestic Product (GDP) or large population are both present."
" The catastrophic rainfall caused the collapse of two dams, unleashing a 7-meter (23-foot) wave, according to the International Committee of the Red Cross (ICRC). The water rushed toward the coastal city of Derna, wiping out entire neighborhoods and sweeping homes into the ocean. " as well as everything else, f.ex topsoil
" A study last year by Erich Fischer of the Institute for Atmospheric and Climate Science in Zurich found that the risk of what was "once in a thousand days" hot weather has already increased fivefold.
His modelling suggests that it will double again at 1.5 degrees and double once more as we go from 1.5 to 2 degrees. The probability of even more extreme events increases even faster."
