dabize Posted April 8, 2012 Author Share Posted April 8, 2012 http://www.unh.edu/news/cj_nr/2012/apr/bp02warming.cfm More PETM information from non-marine sources seem to strengthen the argument that "hyper thermal" events during this period have a common mechanism and were global in their effects. To me, this strengthens the methane gun type mechanisms at the expense of one-off possibilities such as asteroids or localized phenomena. Not sure it this changes the big picture here, but it is another piece of the puzzle...... Link to comment Share on other sites More sharing options...
dabize Posted April 24, 2012 Author Share Posted April 24, 2012 Bumped for this relevant entry at SkS, in which the effect of increased heat wave frequency/intensity to date is discussed, and relevant papers linked. http://www.skepticalscience.com/global-warming-causing-heat-fatalities.html#commenthead My reaction - adaptation may work under circumstances where AC is available and population shifts due to AGW have not yet begun (even this is somewhat at issue in the linked discussion). This isn't going to be possible once multiple stresses (decreased AC, poverty, higher temps, longer heat waves, weaker infrastructure due to overstretched municipal resources, etc) start to operate.

aslkahuna Posted April 25, 2012 Share Posted April 25, 2012 This sounds intriguing, but I'm not quite sure i understand and I'm not sure where to start asking questions. Do you have a link to more information on this? Thanks. For the best information on wasted light (aka light pollution) Google the International Dark Sky Association. When you look at all those pretty pictures from ISS showing the city lights on Earth-bear in mind that most of that light and hence the energy to produce is going to waste as it serves no useful purpose except to prevent us from seeing the night sky and to make money for the Power Companies (and their paid off Politicians). Reducing light pollution is one way to reduce our use of fossil fuels and hence CO2 emissions. Steve Link to comment Share on other sites More sharing options...
aslkahuna Posted April 25, 2012 Share Posted April 25, 2012 And I'd be more inclined to haul my telescope out to the back yard for a little deep sky observing! Damned light pollution. Tucson is better than most cities in this regard but even so my 10 incher sits mostly unused now since faint fuzzies are beyond its reach now. It is sad-we are children of the stars and the Universe as we are made of stardust yet we are denied our birthright to see the Universe we are part of just to feather the pockets of a few greedy people.

Steve It's one thing to view deep space objects all dolled up in colorized magazine photos. The grandeur is awe inspiring. It's quit another thing to glimps bland, gray photons first hand through a telescope using averted vision near the limits of detection. Those photons are uniquely yours, strait from a faint streak or smudge that is a distant nebulae or galaxy.. At least I have my memories. It's better to have loved and lost than to never have loved at all! Link to comment Share on other sites More sharing options...

So true-and how's about that faint little dot that is barely visible which is a Quasar the light from which is older than all life on Earth Steve Link to comment Share on other sites More sharing options...
dabize Posted June 9, 2012 Author Share Posted June 9, 2012 Bumped because the current increase in MEAN global temps doesn't begin to tell the story. The kind of heat waves that can kill enough people to have a demographic impact on some societies aren't very far in the future. http://ibnlive.in.com/news/no-respite-from-heat/260756-60-117.html http://www.deccanherald.com/content/251267/heat-wave-sweeps-andhra-pradesh.html Some more indications of just how little wiggle room there is for human physiology at the top end of the temperature scale, especially in countries with large numbers of poor. Nearly 60 degrees Celsius (135+ degrees F) in Indian coal mines at the end of May = multiple system failure But fear not!
