While I am 100% on board with the "carbon bad, not carbon good, global warming = real, made by man and a real prick of a problem" message, the biggest fault made by people like Maher etc in prosecuting their case to the "sceptics" is reliance on bad information.

For example, the sums have been done on solar and wind, and generally speaking, wind is only borderline viable for supporting a society (and that's only if you don't add the cost of some form of buffering/storage). Solar, particularly home roof grade, is fucking awful, and essentially a waste of time compared to tracking mass production arrays. In terms of energy to build/install/maintain/remove, it barely pays for itself. Solar thermal is also more efficient (helios arrays etc), but the two best bang for buck technologies for producing massive amounts of power at a very low carbon cost are nuclear and hydro.

And they are two technologies that people seem to want to get rid of. Germany shuttered it's nuke capability after Fukushima (and added more coal capacity). Italy's solar market has fallen in a heap, France is almost carbon neutral only because it is predominately nuke powered. One of the original climate change warriors, Dr. James Hansen of Nasa, is fully supportive of nuclear power, and get's constantly lambasted by green types because they do not want nuclear power to play a part.

Refutation of solid science and willful ignorance is not solely the province of people who deny climate change, and it's no less deplorable.

Because Fox News, Rush Limbaugh and the rest... "CO2 is good for the Earth, it helps plants" (ignoring that most plants are absorbing about as much CO2 as they can already, and ignoring the bigger problem that very little of the Earth is green, and no walls or ceilings to keep the CO2 where plants are), "compact fluorescent bulbs are stupid, they have mercury in them!" (ignoring that the mercury in them and the mercury put into the air by the power plant is less than the mercury put into the air by the power plant to power regular bulbs). And the news media paints it as a debate, having one climate change scientist debate one climate change denier (though the media still refuses to call them deniers and paints them as skeptics) and this isn't just the right wing media, almost all the media in the US presents it as a debate. They don't present the fact that a 97% consensus exists.

Then there is religion. They talk how insane it is to assume that humans, made of God could destroy God's work. That we can't damage the Earth as God made it... of course they take the idea of destruction literal, and not in the way people actually mean when they say it's destroying the Earth. They also don't care about the repercussions of future generations as "Jesus is coming soon, well before any of this will matter"... more or less an actual quote. They believe also that God has granted mankind all authority over the Earth and not that it was stewardship over the Earth, so we can and should do whatever we want.

There's also ignorance. The media, especially the right wing media, portray the idea of climate change as presented is being presented as being only 100% caused by humans, they claim that the pro climate change scientists won't acknowledge any part of it might be natural. The media is playing it as an all or nothing scenario, either humans caused it all, or caused none of it. This isn't what any scientists are saying. They are just pointing out the natural uptick vs the uptick we are seeing is explained by human burning of fossil fuels, and that's what the 97% consensus is about, the uptick we are observing vs what would be expected naturally. But not understanding, and thinking science is ignoring all possible natural causes, they deny the whole thing.

Heck, just look at the media uproar over the supposed mini ice age that is coming in 2030 or so. Of course the actual paper never mentions an ice age or climate at all, and neither did the presentation. The problem was the press release for presentation mentioned the Maunder Minimum and linked to the Wikipedia article about it, and from there the media assumed that would mean a new mini ice age, even though the mini ice age during that time was started before the Maunder Minimum. Nobody in the climate change community is really calling for a mini ice age (just like it was never widely thought in the 70s that we were heading for global cooling, it was understood even then it was warming, the cooling thing came from an article in Time if I recall correctly, not exactly a peer reviewed science journal) come the 2030's, at best we may get a very small slow down of the warming, but CO2 levels are 40% higher than during the Maunder Minimum. Anyhow the media tends to mislead the public with things that wasn't actually said. The right wing media machines especially know that their audience won't vet their sources or information and will trust them and talk about conspiracies to hide the truth. Heck most of the media never even cleared the air over climategate emails, so most of the deniers still cite the climategate emails as a valid thing, even though in context and with scientific understanding none of the climategate claims are valid, and in fact still point to global warming... (http://www.iflscience.com/environment/mini-ice-age-hoopla-giant-failure-science-communication)

There's also the change from "global warming" to "climate change" which they don't understand to be an escalation of the term, and think instead it's toning it down.

Maybe it's just me, americans seem incapable of understanding that global warming is not up for debate but a reality that affects mankind right now. Why?

"The most hotly debated science issue these days is global warming"

Nope.

So, 8 seconds in and this is already so fucking stupid I don't even need to rebut it.

Oh hey, it's Fox News! Well, they're absolutely my first trusted source about climate change (or anything for that matter).

Maybe it'll get better.

It didn't. Downvote.

Sweet Bastard Zombie Jesus!
This guy claims that global warming is happening because the core is hotter that it used to be, not because of anything people did or the atmosphere at all, then he goes on to contradict himself by saying this bit of cranial rectosis inspired insanity....

Climate Myth VS What the Science Says
"the warming trend over the Northern Hemisphere, where virtually all of the thermometer data exist, is a function of population density at the thermometer site."

30 March 2012 (Source)
Urban and rural regions show the same warming trend.

What a brain dead tool, followed only by others of his ilk.

This spacecraft is about to start collecting regular data on the energy balance of the whole Earth - an important additional set of data on global warming. Of course the spacecraft was ready about 15 years ago - but Republicans did not want it to fly because (1) they hate Al Gore, and (2) they don't want us to know what they are doing to our planet. ("Close your eyes and vote Republican!")

Another desperate attempt by the science community to get people interested in climate change. The ice ball is the polar ice caps, and the cats are global warming.

Yes, you did say all that, but you also said none of that is a problem, at least not one to be really worried about. To me, that sounds a lot like climate change denial 3.0, where 1.0 was 'it's not happening at all, don't panic', 2.0 was 'it's happening, but it's natural and normal, don't panic' and 3.0 is 'it's human caused, but no problem, don't panic'. All of those are arguments designed to stall, not to be correct. If I'm reading you wrong, I apologize, but I've heard that argument before from those definitely in that camp.

If the IPCC says it won't be disastrous, yes, we would disagree, because I say it already is, and so have they in their summaries of their last few reports. Just abnormal drought alone is disastrous in many places worldwide already, as is increased flooding in some areas. I did not read the entire PDF's, only what you quoted because they were only linked as downloads/files, and I don't download files from sites I don't recognize.

I linked the first google search pages that came up with water/glacial data, not the other dozen that said the same, or near the same thing, not the NOVA on glacial retreat that said the same thing, not the movie on the same topic with photographic proof of the retreats-Chasing Ice. You ignored that they did list their source for the 2/3 of Chinese cities low on water and the 50% loss of glacial mass per decade as the Chinese military and claimed they were source less so easily dismissed.
As for the diatoms and shellfish, I've seen numerous studies on them, and again just grabbed the first one that came up in a search with data. You seemed to dismiss it as well, but it's not alone. In one snail study I saw, the woman said the last few years it had become nearly impossible to get measurements because the snail shells literally turn to paste in her fingers and weighed nearly nothing! I'm glad to read now that you don't disagree that it's an issue, you only think it's not severe?

I'm not holding my breath on fusion or fission, we've heard the 'we're only 5 years away from fission/fusion' line before about as often as 'Iran is only 2 years away from having a nuclear bomb', but we can agree on wind and solar, except I say it is great for base load, you just need to pair it with micro hydro storage (pump water uphill with surplus solar/wind, then run micro hydro at night). Small solar/wind also decentralizes production, safeguarding from terrorism, and is quite cost effective. Mine paid for itself in well under 10 years.

My issue with your position is that what we do today just with CO2 production reduction won't really effect the atmosphere for 20-200 years (the accepted lifespan of 65-85% of atmospheric CO2, the remaining 15-35% takes thousands of years to be trapped) and that's only IF the ocean CO2 sink continues functioning, so we're already well past the point of avoiding moderate climate change. Without quick action, feedback loops like methane and/or ice sheets melting make the problem exponentially larger and difficult/impossible to manage at all. It may already be too late even if we cut to zero CO2 tomorrow, but it's certainly too late to avoid more, massive, unsolvable global issues if we don't even mitigate them before 2050.

Let's not get into the quagmire of global dimming from sulfur in coal actually mitigating a large part of expected global warming by reflecting sunlight. I've yet to hear a plan or study involving that variable.

Thanks for your "very scientific" definition (just like GenjiKilpatrick's "evidence" for global warming, saying "OMG, Global Warming is real because it was 70 degrees in Georgia!")

No, unlike you, I don't confuse partisanship with data... Nor do I look for arbitrary reasons to discount a person's entire argument because the rules of epistemology suddenly no longer apply. On the contrary, I choose to instead examine what the data actually shows before arriving at my own changing thoughts on the matter.

But I guess, for you, the data isn't as important as the source, so long as your pre-cooked distortions of reality aren't disrupted by something as pesky and difficult to conform to one's beliefs as the FACTS... (remember those?)

But, yes, you are absolutely right about fucking yourselves. Perhaps you should spend less time online and save some electricity. (Or maybe it's too much for you to actually Walk The Talk instead of just bloviating online.)

I went to a gas station recently. Lots of people were pumping gas... And none of them seemed to care very much about your ideas of oil company fellatio. They also didn't seem concerned at all about crackpot climate change "theories"... (Go figure.) You should get out there and yell at them for ruining the planet, ChaosEngine. I was also at an airport recently, too. There were lots of planes burning fuel. You're not making a single dent on oil consumption with your tirades... Perhaps you should try another strategy and see if anyone cares.

(Haha.. Of all the fictional "crises" you could choose to be an alarmist about, you've chosen one on which you have zero impact! But, hey, for all I know, you're just addicted to the adrenaline rush of faux outrage. Lucky for you, I'm here to feed it...

See, this is why it needs to be shown the rise in joules, and a total energy rise in the entire planetary system, not just some arbitrary surface temperature rise....because people like you (no insult intended here) genuinely see the small relative figure and think...eh its no big deal.

Its a huge deal.

We are losing gigantic chunks of the otherwise permanent ice shelf in south and north arctic areas.

With those gone, we have otherwise what would have been massive mirrors, which reflect light...now acting as big old heating blankets (the water is effectively a black body to sunlight, absorbs it like no other..).

That right there is called a positive feedback loop. You start with something small, and within no time (geologically speaking), its in runaway growth.

The frozen tundra in greenland is home to enormous pockets of trapped methane....not for much longer. (source: http://www.nature.com/ngeo/journal/v8/n1/abs/ngeo2305.html)

Methane's impact on global warming (i.e. energy RETENTION within our planetary weather system) is 25 times greater than an equivalent amount of C02. (source: http://epa.gov/climatechange/ghgemissions/gases/ch4.html).

Further to this video, when you heat up the ocean systems beyond a certain threshold, the natrual pumping systems which circulate warm surface water to the deeper parts of the ocean for cooling, just flat out stop working. (source: http://www.ncbi.nlm.nih.gov/pubmed/19895974), leading to the slow heat-death of a vast swath of temperatue sensitive biomes....which, when they are active and growing healthily, actually contribute to c02 depletion (carbon based lifeforms 'use up' carbon to be 'made').

...I could go on, but you see....even just a cursory glance at some of the 'smaller' impacts is pretty compelling enough to consider the phrase 'no big deal' a bit of a misnomer.

Do your research....it is catastrophic, and it is likely to happen in your lifetime (if you are under 30 atm).

Your grandchildren and great grandchildren will be living in a drastically different global environment.

No biggie though, cause we got electric cars coming online in the next 30 years or so

Firstly, it's the same logic FoxNews uses so why can't I?

" Looks it's snowing. Global-warming, my ass!"

Secondly, weeks of unseasonal whether ARE evidence of a Change in Climate.

Combine this with the fact that..

More than 45% of the Arctic Ice Cap has melted away since the 80s..

And it's clear that the rapidly industrializing Eastern world has vastly accelerated Anthropogenic Climate Change and Global Warming.

Why can't conservative accept facts?

Bollocks.

He's not taken seriously by one guy who's a student and tv intern and one other meteorologist. It's hardly "by any meteorologist", but hey, 2 people is absolutely a representative sample for the climate denying brigade.

Most meteorologists agree with Bill Nye

Regardless of the cause, do you think that global warming is happening?
Yes 89%
No 4%
Don't Know 7%

How sure are you that global warming is happening?
[Asked if answer to Question 1 is “Yes”]
Extremely sure 46%
Very sure 37%
Somewhat sure 16%
Not at all sure 1

Bill Nye, the bloviating low-information "climate guy" not taken seriously by any meteorologist.
