I think that the biggest problem in getting accurate info is the connection to money, agenda based groups that get financial gain or political power will undoubtedly keep up the rhetoric of doom and gloom to keep the money flowing. I heard one of the chief scientists for Australia has said that we contribute .003% of the worlds greenhouse gases so nothing we do will make any significant difference, another has said the opposite.
Now compared to an active volcano that can spew out hundreds of times that amount not to mention the other contaminants such as sulfur dioxide, particulate matter, ect, 50-70 volcanoes are active (erupting) each year and there is an estimated 5000 volcanoes under the sea of which a huge number are active which also makes the seas more acidic, which kills off sea life which exacerbates the situation. At any given time, there is an average of about 20 volcanoes that are erupting above land, so we are fighting a loosing battle just on that front alone but we are spending hundreds of billions of dollars to reduce CO2 for no gain.
Due to tectonic plates shifting, moving up, down and sideways, this will not end anytime soon and we can't do anything to stop that from happening, so whilst islands may sink, the Maldives spring to mind and that is regrettable, but unless you can stop a continent from sinking that will happen no matter what we do, that is not climate change that is continental plate drift, we are also deluding ourselves if we think that we can stop CO2 rises happening to any significant degree. Factor in that the planet's axis tilt is moving about 15m year northwards our weather is going to change no matter what.
Our planets CO2 levels were much higher millions of years ago than they are now as the planet had much more plant life, continents move and weather patterns change, plants convert oxygen to CO2 at night and reverse it during the day when photosynthesis kicks in, also producing carbohydrates, as they die it also converts back to CO2, methane as well as others. Lastly there is that matter of that big old yellow circle in the sky, it's output also varies with time, it is not constant and that has a bigger effect on our planets warming than anything humans can do.
So at the end of the day it is anyone's guess who is right is right, having said that, what we do know for a fact and are sure of is that the world weather is changing but it has been changing for far longer than humans have been around in our present form as in long haired and dragging knuckles on the ground with no technology. Actually some of my friends still look that way!. Whilst we should make less pollution because it is the right thing to do, we should not, at the expense of spending futile hundreds of billions of dollars for no gain. We should probably concentrate on reducing population growth as that will most likely kill us off faster.
Money will always skew any facts that come up in the media, what's that saying, don't let the facts stand in the way of a good story!! Anyway that is my 2 cents worth on the subject and others are free to disagree.
