adressing the climate stuff:
as a scientist who has read the papers: there is an unusual fast change in temperature, co2 concentrations and ocean pH value. since the number of volcanic eruptions didn't spike and the sun is quite silent, no natural source of those changes were found. thus there is a possibility of an imbalance induced by mankind.
although many studies are carried out, no natural origin of those changes has been proven so far.
changes in all those values above wouldn't be critical at all, life is quite adaptive. it changes a few million species and continues on. our influence towards that is neglectible. there is just a chance that these changes may have negative influence on our lifestyle and wealth - thats why it became spreaded by mass-media and politics... usually we don't get this kind of attention while the work is still in progress
adressing the bitcoin stuff:
lets hope the asian maniacs crash the market down to 500, i want to buy some more bitcoins. but i would rather bet on a consolidation, followed by a massive rise by the end of the week. new money is incoming, fueling a new bubble?
