the suggestion that global warming is largely human-induced is most likely one of the biggest shams of our lifetime. there has been constant climate change every since the beginning of earth's existence, and if you actually understand earth's processes and science behind weather and climate balance rather than believing everything people tell you (i.e. we are causing global warming) then you too will realize we are being fed lies. anyone can throw up a chart showing exponentially increasing global temperatures in response to increasing CO2 levels, but does that make it true? hell, recent studies have argued that CO2 levels increase in response to temperature increases rather than vice versa which is a starting point for debunking the human-induced global warming idea altogether if true!
don't get me wrong, i'm all for energy and environmental conservation. but climate change is inevitable. we understand "normal" weather and temperatures relative to our short time and to what we can measure in fossil records/ice cores etc. so how do you explain the record-setting strong la nina (cooling of the pacific ocean waters off the western south american coast) that we are currently seeing? turning the pacific waters cooler than normal removes a primary heat source for much of the globe as the pacific ocean plays a major role in global climate and weather due to its size.
and temperatures cannot continually get warmer and warmer. there's a limit. basically, the warmer it gets globally the more difficult it is to get any warmer as there is limited amount of heat energy available (recall that temperature is a measure of heat energy), unless somehow the total available heat energy increases somehow (changes in solar energy discharge from the sun directly or shifts in earth's position). we won’t continually get warmer and warmer.... that’s not logically possible (limited energy) and the earth will snap back to fight it off. also, there is only so much water vapor the atmosphere can possibly hold before you get condensation (warmer temps cause more evaporation which causes increases in atmospheric moisture), which means that as the arctic regions warm... there will be much more precipitation in those areas. arctic regions will remain below freezing causing all the precipitation to fall as snow. more snow falling over and over thus leads to the rebuilding of the snow pack and glacial formation back in those regions who have seen a reduction over the last decade.
