I almost feel that should be a prerequisite to posting on this thread. If someone doesn't think it's the altered radiative balance from rising CO2 levels...... what's the cause for the observed warming trend? I have no problem examining an alternative explanation but an alternative explanation needs to be provided to examine....

In the past the sun was dimmer, and the timespan you referred to the Earth was ice free. Could we live on an ice free Earth absolutely and While it would warm it would be far from boiling. BUT the impact on humanity of 200+ feet of seal level rise would be quite problematic.So why did the earth not burn up when CO2 was higher than it has been now by up to 20X for millions of years? It rarely has been anywhere near as low as it is now. Oh yeah, I forgot you and nwdiver were not aware that the earth existed before the Vostok ice core record 400K years ago, lol.
Earth experienced an ice age 450 million years ago, with CO2 somewhere between 2000 and 8000 ppm. According to Hansen’s theories – all life on Earth should have been extinct before it even evolved.
And...
According to peer review from 97% of leading climate experts, the earth should have heated up above the boiling point and all life should have been exterminated. The fact that it did the opposite would appear to undermine their already highly dubious credibility.
Ice Age At 2000+ PPM CO2
Keep on embarrassing yourself.
Climate change isn’t coming for Napa. It’s here, explains S. Kaan Kurtural, UC Davis professor of viticulture and enology.
“Napa already has moved into another climate category,” Kurtural says. By “climate category,” he’s referring to the Winkler Index, a Davis-developed scale that maps which types of grape varieties can grow within specific temperature bands.
Cabernet Sauvignon can grow successfully in the Winkler Index’s Regions II, III and IV — but Region V would be pushing it. In 1944, when the system was developed, it put most parts of Napa Valley on the cool side of a Region II; now, most parts are a warm Region III or even a Region IV.
Napa wineries confront climate change by planting new experimental vineyards — without Cabernet Sauvignon.

Greta as climate culture warrior
How Greta Thunberg became the new front in the Brexit culture war
How Greta Thunberg became the new front in the Brexit culture war | Gaby Hinsliff
It’s selfishness, rather than misogyny, that is surely the root cause of this rage at the very idea of being asked to give up any individual freedom – to fly, drive, eat a steak, carry on with our oblivious lives as if nothing was happening – for the greater good. But female climate campaigners are perhaps uniquely prone to press the buttons of what might be called toxic libertarians; people who combine a burning desire to do what the hell they like with fury at the very idea of being nagged, nannied or told what to do, especially by women.
But those arguments are giving way to something altogether nastier: not climate crisis denial, so much as climate crisis nihilism. The nihilists don’t necessarily deny that the planet’s frying but, essentially, they refuse to feel bad about it; they want their sunshine holidays and their 4x4s, come hell or (possibly quite literally) high water, and screw anyone who gets in the way
Yet however her parents choose to deal with this, the broader problem she highlighted remains. A society that cannot bear to be lectured by its children, even when they’ve got a point, while the adults are behaving like spoiled toddlers refusing to clean up their own mess, is one that can never progress. Perhaps our children can finally be children again, when the rest of us grow the hell up.

What about the sun? There has been war
What about the sun? There have been much warmer times where there was no Ice. It certainly wasn't caused by burning fossil fuels. Greenland is called Greenland because they were growing crops that cannot be grown today. We are currently in an Ice age. Also have you seen the new documentary from Michael Moore who is certainly not a global warming denier? Here it is and it basically states that wind, solar, etc. cannot provide our needed energy.
New Michael Moore-backed doc tackles alternative energy
Actually Greenland is called Greenland because it sounded better than Iceland. Erik the Red was trying to convince settlers to come, and it's kind of hard to get someone to settle in a place called Worse Than Iceland.
It's been covered in ice for thousands of years, as the glacier core samples show.
Here's what science says about your denial talking point.

Irrelevant. The changes we are seeing in the last 100 years has nothing to do with the strength of the sun.
False.
He's wrong. He's also not denying that climate change exists, as far as I can tell.
@rays427
Note the renewables . Wind solar and those 2 blue circles representing present world use of energy.
Sure seems like just solar and wind could replace easily AND it’s manufactured energy, then delivered for free. All we have to do it use it.

Nope, no climate change happening. Things are cooler'n ever in the oceans. The planet's cooling, not warming.
