Mr. Nye had come to talk to them, and a few thousand of their friends, at Iowa State University. If he were a politician, college students would be his base. Instead, he is something more: a figure from their early days in front of the family TV, a beloved teacher and, more and more these days, a warrior for science. They, in turn, are his fans, his students and his army.
This improved certainty allows us to say definitively that both Antarctica and Greenland have been losing ice,” lead author Andrew Shepherd of the University of Leeds in Britain, told reporters. Not only that, but the pace has tripled from the 1990s, the data indicate.
Combining satellite data from dozens of earlier studies, the study “shows that the Antarctic and Greenland ice sheets have contributed just over 11 millimeters (0.4 inches) to global sea levels since 1992,” he added. Two-thirds was from Greenland, a third from Antarctica.
That’s 20 percent of all sea level rise over the last two decades, with the rest mostly from thermal expansion of waters due to warming sea temperatures, the authors noted. In recent years, however, the percentage “has gone up significantly” to nearly 40 percent, added co-author Michiel van den Broeke from Utrecht University in the Netherlands.
hot as balls today. we are vacationing in sd and did not expect this…
This kind of heat is unique. It’s a new peak for me. One would have the heat but not the humidity this time of year with Santa Ana winds, but it seems like those are a thing of the past. Were this a Santa Ana, the heat would have dropped to at least 85° in the car by that time. The humidity, the monsoon flow, holds the heat and won’t let it go.
Once properly developed, nuclear fusion could provide an unlimited supply of electricity, with no significant environmental impacts.
