Daley and many high ranking officials in the city of Chicago's government were warned in advance of the potentially fatal effects of such a heat wave, but as temperatures soared over 100F (with a heat index nearing 130F) very little was done. ... The group that was most affected by the events of the July, 1995 heat wave was the increasing population of poor elderly who live alone in social isolation, especially those who live in areas with exceedingly high crime rates. ... Of those that were least affected by the heat wave, Chicago's Latino population stands out above all others. ...

As the poster accompanying this report illustrates, the standard theory explaining sonoluminescence is that the sounds waves applied to the flask and moving through the liquid to the bubble create a shock wave within the bubble. ... So long as the amplitude of the sound wave remains stable, the bubble will continue to emit light. If, however, the amplitude of the sound wave is driven too high, the bubble will quickly disintegrate. ... Rather than heat creating the light, Prosperetti believes that the speed of the stream of water forced from the bubble by the sound wave causes the bubble t...

From the list given, many of these are a reaction to the warming of the planet which is because of the increased level of heat-trapping carbon dioxide. ... When the sun emits its light energy, the earth absorbs it and warms the earth, this heat is supposed to be reradiated back into space but because of these green houses gases, the heat is trapped on earth, which in turn drastically changes the climate.
