I have taken a liberty of extracting these last two posts from "2015 Spark no longer 21-kWh and now 19 ???"
I am personally really interested in both topics, just not in the same thread. Please feel free to continue your discussion here.

There is too much blind faith in the cult of global warming. Slanting the numbers or picking and choosing only the data that supports the theory does occur. Some folk turn a blind eye as they figure "the end justifies the means".
Some people have become very wealthy via promoting and taking advantage of a "green" agenda.
It's a real temptation to get on a power trip with a cause that can not be questioned such as "save the earth". Some folk like playing the martyr role and "do with out" to "save the earth" . There is even a small cult of people in western civilization . That make a point of "saving the world" by not owning a fridge or freezer. They are not Amish either.
Planet earth has undergone countless temperature swings before mankind had any influence. There are frozen buried jungles in arctic regions. There is also evidence of ice age glaciers being halfway across continental USA.
Earth's source of heat is the sun. If anybody hasn't noticed. The sun has several short and long term cycles in which it's output significantly changes.
Facts are facts...cults are different. Most scientists aren't of the ilk you speak of and having been in the climate science and engineering industry, I can assure you our effect on the planet is real, concern is warranted, and the direction we are going in is not a good one. I don't believe in doomsday scenarios as far as climate goes but it won't take much to destroy the very delicate balance of life we now enjoy (harvests, ocean life, etc). A few bad years and millions of people will be in trouble.
The planet has gone through many changes but the rates of change have been slow. Nothing in recorded or date history has ever caused such an equivalent rapid rise in CO2 density in such a short period of time as we have seen in the last 250 years or less...coinciding directly with the industrial age and high emissions.
What we are seeing now is the Earth trying to adapt to the high concentrations of CO2 that we have put into the atmosphere....a stable system that has been disrupted by a large input. We will see the oceans absorbing much of it...acidifying the oceans. We will see temperature extremes....areas getting warmer and areas getting cooler. The system is a feedback system and has the possibility of going unstable or settling to a new stable point...one which isn't favoured by us for a good quality of life.
So far the power trips of corporations and companies to trash the planet has far outpaced any power trip from any green movement. So let's not overhype the green peoples' impacts as something it isn't.

I burned a record amount of firewood 2013-2014 to keep warm during our longest and coldest winter in decades.
CO2 doesn't mean beans in the grand scheme of things. There are several other gasses being vented one way or another into the atmosphere. Just how exactly we are going to stop methane from rising for the ground and vented from various animal or insect hind parts? Then my favourite, the volcano. Ever see the troubling figures on what those natural phenomena spew ? At least one earth wide mass extinction in the past was due to volcanoes, no humans involved.
There are wooly mammoths in the Arctic deceased from something that killed them quick. Some still have the grass in their mouths they were chewing when struck down.
The USB fob saved more trees than any greenpeacer ever did.

I don't find the usual climate denier arguments believable, but I fully agree that natural phenomena can and does affect climate, just as we humans are affecting climate with dumping CO2 into the atmosphere that has been sequestered for millions of years.
http://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa
The final explosive eruption of volcano Krakatoa was heard 3,000 miles away; caused at least 36,417 deaths; 20 million tons of sulfur released into the atmosphere; produced a volcanic winter (reducing worldwide temperatures by an average of 1.2°C for 5 years); and was the loudest explosion in recorded history.
Global climate[edit]
In the year following the eruption, average Northern Hemisphere summer temperatures fell by as much as 1.2 °C (2.2 °F).[9] Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888.[9] The record rainfall that hit Southern California during the “water year” from July 1883 to June 1884 – Los Angeles received 38.18 inches (969.8 mm) and San Diego 25.97 inches (659.6 mm)[10] – has been attributed to the Krakatoa eruption.[11] There was no El Niño during that period as is normal when heavy rain occurs in Southern California,[12] but many scientists doubt this proposed causal relationship.[13]
The eruption injected an unusually large amount of sulfur dioxide (SO2) gas high into the stratosphere, which was subsequently transported by high level winds all over the planet. This led to a global increase in sulfuric acid (H2SO4) concentration in high level cirrus clouds. The resulting increase in cloud reflectivity (or albedo) would reflect more incoming light from the sun than usual, and cool the entire planet until the suspended sulfur fell to the ground as acid precipitation.[14]
Global optical effects[edit]
The eruption darkened the sky worldwide for years afterward, and produced spectacular sunsets throughout the world for many months. British artist William Ashcroft made thousands of colour sketches of the red sunsets half way around the world from Krakatoa in the years after the eruption. The ash caused "such vivid red sunsets that fire engines were called out in New York, Poughkeepsie, and New Haven to quench the apparent conflagration."[15] This eruption also produced a Bishop's Ring around the sun by day, and a volcanic purple light at twilight.
