So, I'm open to other explanations. Perhaps you can give me other reasons besides " it's been this warm before", which isnt really a reason to begin with. The folks who insist that we are not the primary cause of this round of planetary warming should check out NASA's website where even with the US current administration it spells it out quite clearly. Pay particular attention to the CO2 level versus total solar radiation graph. It really isn't worth discussing because nobody ever really examines the evidence and none of us are capable of developing our own accurate statistics, so nobody changes their mind on issues like this. It's just that the hard science is ignored by one group that makes this debateable. In all honesty, can you point to any climate studies that were put together by reputable universities, or government agencies, that were peer reviewed and published in actual scientific journals? What possible gain is there for the huge percentage of geochemical climate experts to push what you consider to be bogus science. Has there ever been scientific quackery before? Of course there has but on a scale like this? Pehaps it is vaccines that are really causing warming.
