In the 1950's the most powerful computer was the Univac housed at the Franklin Institute in Philadelphia. It was mainly made up of diode tubes that were about three foot high and a foot wide. It could do simple math and play Christmas carols. The smartphone you carry everyday could not even be imagined at that time. Developers did not stick their heads in the sand, thankfully, and moved ahead to give us the technology we have today. If Trump were in charge then we would still be adding with our fingers and toes.
The same principal applies to alternative energy sources. The only real resistance is those with money in fossil fuels and the morons who insist on driving a 500hp diesel, 4 x 4, to go grocery shopping.
Would you trade your smartphone for the original cell phone. I think not.
It's pretty well documented how much fossil fuels we burn. And the laws of chemistry are irrefutable - burning them makes CO2. There is also irrefutable proof that CO2 is a greenhouse gas.
Irrefutable.... Lol... When predictions fails, just make predictions beyond the life of anyone remembering it... Global warming used to make predictions in your lifetime and then when it was wrong over and over, their predictions are now beyond your lifetime...

When did it start warming, and how can we know for sure that it really is warming?
There are many very good books on your question. I suggest reading one. The issue is long settled in the science community, no point in rehashing old news at this point.
I'm beginning to believe that most climate change denying posters in this thread are nothing but trolls.
Some might be. I suspect some posters work in the oil and gas industry and they feel their livelihoods are threatened if we all acknowledge climate change is real and we have to take action to address it. So they go online and push the denier agenda, hoping to buy more time and another paycheck before we come to our senses and realize that most oil, gas and coal needs to be left underground where it's meant to be.
Where I am seated, here in SE Michigan, glaciers extended straight up more than a mile.
That's a lot of ****ing ice!
It was also less than 18,000 years ago - a blink of an eye in geological time.
So, what caused that ice to melt?
The answer is at your finger tips...google...
Ice cores from both Antarctica and Greenland show that the last ice age started to become milder 19.000 years ago, completely in accordance with increased solar radiation from the earth’s favourable orientation in its orbit around the sun.
It takes circa 10.000 years for an ice age to gradually come to an end
That figure is for Fort Yukon, an interior location at 66° north, right at the Arctic circle where the sun never sets in summer. Anchorage is a coastal city at 61° north that does see darkness even on the longest days of the year. These are not equivalent comparisons, but I suppose if you want to play that game then I can refer you to this map that shows the temperature anomalies for July:
This is NOT normal. How is this so difficult to understand?
Those are data points, NOT proof.
