Supernovae data from the 1950’s to 2007 show trends very worrying for the fate of the whole universe.
The Magnitude (brightness) of observed explosions, after hovering for several decades around the 20 mark, has recently dropped to 15 (i.e. towards brighter supernovae).
Furthermore, the number of observed supernovae has been increasing at an exponential rate, again after many decades below 50 per year, to 95 in 1996 and a little less than 600 in 2007.
The fact that this is happening exactly as anthropogenic greenhouse-gases emissions are on the increase, cannot be just a coincidence. If this will not convince Governments about the importance of stopping CO2 emissions, nothing will!
UPDATE: In case you missed it…the rings of planet Uranus are changing too. Help! Help!
