The problem for most people "concerned" about "climate change" is the consumer society. Anything that sheds control over lifestyles is bad. The issue is not really climate change at all.
The empirical evidence is against you on this one.
During recent recorded history, the Earth's surface cooled and warmed without significant changes to CO2 levels.
Of course, the really important question, the one that never gets answered, is what effect does and will increased levels of CO2 have.
We have more than doubled the atmospheric CO2 level, yet the surface temperature, even by the warmer's account, has barely budged.
Seems the answer to the question is, not much.
Scientist have already addressed why increased CO2 levels elevate warming, pick up any document from NASA and you will see the science. CO2 at over 416 ppm is a significant reason why we are warming, a temperature increase of 1 Deg C in around 100 years does not amount to "barely budged". DO you have any idea the amount of energy required to raise the temperature of the earth and it's oceans 1 deg C.
Our per capita consumption of fossil fuels even with out reduction over the past few decades is 3 times that of China and that has been the case for decades. Yes China and India generate more because their population is greater than ours.
There's your solution, then... ban abortion and mandate every person in America pump out at least 10 kids!
Yes to both, but we all know that the real issue here is that the political party that aligns with your side of the culture war is also the party that has a vested interest in preserving the status quo on environmental regulations. The actual science or facts don't matter.
If the Democratic Party denied climate science but positions on all other issues were the same, you would probably be on the front lines fighting for climate action.
So there is no possibility that climate change is happening naturally? The science is settled and that there is a consensus among all or a vast majority of climatologists that man is the cause of this climate change?
I’m asking for evidence of climate change and you rebuke with some political pretzel logic that if democrats sided with this or that then I would side with the opposite. I ask for evidence and that’s the response? What even makes you think democrats are for climate science? We both believe in climate change, we disagree how it happens. To believe the science is settled on the matter is absurd for the fact that science is never settled. Science is a discovery process that turns out to be wrong often.
Pretty obvious that the planet was at one time warmer, no idea why that keeps being brought up as some sort of revelation. That's you claiming that CO2 is a pollutant, but are you denying that it is a heat trapping gas as are other greenhouse gasses. Spare me the semantic argument. Yes plants need CO2, so. There needs to be a balance and right now the balance is off if you look at the numbers.
The planet warms and it cools. The climate is forever changing. I never claimed that’s a revelation. It’s common knowledge, but we disagree on the cause of these changes. The climate on earth has been changing for eons, but now the reason is because of man? Okay, the balance is off. By how much? What is the cause for the balance to be off?
The climate was stable for the last 10,000 years of our agricultural based civilization. That’s about to change really fast, because we continue to spew trillions of tons of heat trapping gases into the atmosphere.
Except for the Holocene Climate Optima (warmer than today), the Holocene Climate Pessimum at the end of the bronze age, (coldest in the past 10,000 years), the Roman Climate Optimum (warmer than today), the Medieval Warm Period (at least as warm as today), and the Little Ice Age (early 1300s to about 1850). Other than all of those large climate shifts, the climate also oscillates due to the Pacific Decadal Oscillation, a cyclical variation in Pacific Ocean water temps. http://www.myweb.wwu.edu/dbunny/pdfs...scillation.pdf
So no, the climate hasn't been stable for 10,000 years, it hasn't even been stable for the past 100 years.

Unless you have data otherwise?
Since 1979 satellite data shows the planet warming at a rate of 0.14 degree (C) per decade. The end of the Younger Dryas period about 11,500 years ago saw warming of 10 degrees C, (18F) in a single decade. Numerous large very rapid changes in climate occurred going into and coming out of the last ice age, but nobody knows how or why they happen.

Similar events, including local warmings as large as 16°C, occurred repeatedly during the slide into and climb out of the last ice age. Human civilizations arose after those extreme, global ice-age climate jumps.
As for taxing, waste of time. Money is not the solution to this problem. I'm not sure there is a way out. Whatever we can do as individuals is not enough, huge corporations contribute far more we can possibly negate.
The Chinese contribute far more than we can possibly negate.

China has nearly 250 gigawatts (GW) of coal-fired power now under development, more than the entire coal power capacity of the United States, a new study said on Thursday, casting doubt on the country’s commitments to cutting fossil fuel use.
We are at 1.1 Deg C (2 Deg F) and going to 1.5 degrees even with radical sudden changes in consumption but we really need to change our habits rapidly.
Right, right right!
And Greenland used to be green and vikings settled there, considering it heavily grounds with lush vegetation.
Hold on, I am confused. Greenland is ice frozen land now. So what, it was, actually, WARMER a thousand years ago, than it is now? So, if temp goes up 1.5 degree, will Green-land become green again?
What is the correct average temperature for the Earth's surface?
Please prove and exact number and the reason why only that temperature is correct.
The Earth itself has no “correct” average temperature. However, our species and the civilization we’ve created does.
