30.8% Climate change is occurring, and it is caused mostly by natural changes in the environment
26.9% Climate change is occurring, and it is caused more or less equally by natural changes in the environment and human activites
25% Cllimate change is occurring, and it is caused mostly by human activities
13.5% There is not sufficient evidence to know with certainty whether climate change is occurring or not
3.8% Cllimate change is not occuring
1. At this point - a changing climate is baked in the cake. Irreversible triggers have been tripped and the climate is pretty much on auto pilot...not a good thing. Independent of whether humans contributed or not is now a moot point...feedback loops are in play. Expect more erratic swings in local weather...dry parts of the country will become drier and wet parts wetter. Of course these changes will effect food supplies...so expect much - much higher food prices. Cutting emissions will only make the changes more rapid - google "NOVA - The Dimming of the Sun" for more info. As an aside, but germane to the CC issue...energy resources are dwindling - food costs rising/food shortages occurring globally- civil unrest occurring globally and 700 trillion in economic uncertainty...well let's just simply say - the chickens are in fact coming home to roost. Buckle up - could get a bit bumpy moving forward.
2. Climate change is a natural, normal phenomenon varying with and produced by solar activity, with some effects from earth's axial tilt variations thrown in to the mix. The sum total of all human activity since the dawn of time is of complete insignificance. Global warming, when it occurs, is a huge blessing for all life on the planet - habitable areas increase, arable land increases, and life is good. During the Medieval Warm Period (roughly 950 - 1250 AD), Nordic peoples farmed Greenland. Even polar bears managed to find a way to survive. Since the planet has shown no sign of warming for the last 15 years, five of six snow events in the U.S. northeast since December accumulated 12" or more each, the first Category 4 "crippling" snow event in the southeast in 18 years, the most ice on the Great Lakes since 1994 (88% of the surface covered), north and south polar ice caps larger than they've been in decades (that Russian cruise ship that was stuck in the Antarctic Ice was populated by a herd of global warming "scientists" there to prove the ice was melting, but froze in ice 4' thick miles from where summer ice pack normally extends), it might be we are closer to another ice age (glaciers grinding down through the northern tier of U.S. states) than we are to a warming period. Maybe the feds should be requiring all humans be driving SUVs.
