Climate Damage 'Irreversible' According Leaked Climate Report

New submitter SomeoneFromBelgium (3420851) writes According to Bloomberg a leaked climate report from the IPPC speaks of "Irreversible Damage." The warnings in the report are, as such, not new but the tone of voice is more urgent and more direct than ever. It states among other things that global warming already is affecting "all continents and across the oceans," and that "risks from mitigation can be substantial, but they do not involve the same possibility of severe, widespread, and irreversible impacts as risks from climate change, increasing the benefits from near-term mitigation action."

Delayed action

[Anonymous Coward]

We'll never do anything about climate change as long as businesses can dictate law, control the EPA, and guide lawmaking through lobbyists. The Supreme Court has literally ensured this.

I can't stand the idea that multi-billion corporations can't afford to spend 1/8th of their profit, if even that much, to operate in a more environmentally friendly manner.

Gotta hoard and accumulate money at all costs, no matter what happens.

That would actually be illogical for an individual to do if they're mostly interested in themselves and their offspring (and people do it which shows how generous some people are, sacrificing themselves for the greater good). A single person giving up 1/8 of their income for the benefit of everyone instead of themselves is just putting themselves at an economic disadvantage. Those are resources that can't be put towards better education for their kids, buying bigger/newer (i.e. safer for themselves) vehicles, etc. This kind of stuff will only work if we agree as a society that everyone has to play along by the new rules, for the benefit of everyone as a whole. A lot of people are completely against this idea (government intrusion on freedom, etc.) but that's the only way we've ever solved problems based on the "tragedy of the commons". If there's a common resource that people have an incentive to exploit, with no limit, for essentially free (e.g. the atmosphere) then they will do it. Sure, we all breath, but there's little/no incentive to breath "more". We can, however, use more energy by burning inexpensive fuel which consumes O2 and releases CO2 into the atmosphere, and we don't, as individuals or as companies, have to pay for that "externality". Therefore we will *never* stop doing it until we all agree as a society to regulate CO2 emissions.

Simple English Wikipedia will come in handy

From the article:

The UN panel since September has published three separate reports into the physical science of global warming, its impacts, and ways to fight it. The study leaked yesterday, called the “Synthesis Report” intends to pick out the most important findings and present them in a way that lawmakers can easily understand. (Emphasis mine)

Why do I have a feeling the report to the politicians will have to read a lot like the Simple English Wikipedia, to the point where it might not be a bad idea to get the writers for that on it.

"Global warming is a bad thing that causes lots of problems. Burning stuff causes global warming. If you keep burning stuff, you will have a bad problem."

Re:Damage or Change?

[Urkki]

Climate has always changed, the concept of "Damage" is only relevant to those affected by it.

You mean, the same way as asteroids of various sizes have impacted into the Earth throughout the history of the planet, and "Damage" is only relevant to those affected by it?

Yes, I agree.

Those are a lot of conclusions to draw when you openly admit that you have insufficient measurements and cost estimates.

single average-sized car puts out 4.75 metric TONS of carbon every year

That sounds an unreasonably high figure.

Petrol weighs about 737g / l, so 4750Kg of petrol is 6445 litres.
Wikipedia says the carbon content of petrol is up to about 85%: http://en.wikipedia.org/wiki/P...
So 6445/0.85 = 7582 litres of petrol contain 4.75t of carbon.
Wikipedia suggests average fuel economy is somewhere around 5l / 100Km: http://en.wikipedia.org/wiki/F...
7582*100/5 = 151640Km - I'm pretty sure that the average car doesn't travel 152Mm/year!

Lets assume you're talking about tons of CO2 rather than tons of carbon.
Apparently we multiply litres of petrol by 2.331 to get Kg of CO2 emitted: http://www.carbontrust.com/res...
So 4750/2.331 = 2038 litres. At 5l / 100Km, this gives us 2038*100/5 = 40760Km - ok, a vaguely more reasonable figure.

Apparently the average company car does around 30,000Km/year and the average private car does about 12,000Km: http://www.racfoundation.org/m...

So the average is going to be well under 41Mm and around an order of magnitude less than the 152Mm you claimed!

I'm certainly not saying that climate change is nothing to worry about - I think it's a big problem and whether or not you think it's man made, dumping vast amounts of crap into the atmosphere can't possibly be a bright idea. But I really wish people wouldn't just invent bogus "facts" to back up their arguments - the arguments should stand up for themselves, if you need bogus data to prop them up then you've got something really badly wrong somewhere.

Re:Impacts

[NotDrWho]

We don't have foreknowledge of shit. It's a pretty epic level of arrogance to think we've suddenly acquired the ability to accurately see 100 years into the future when EVERY SINGLE ATTEMPT in the past to accurately predict anything even 20 years in the future has failed MISERABLY and has been LAUGHABLY wrong.

The only thing that I predict about what this planet is going to look like 100 years from now is that it's going to be nothing like what anyone expects today.

Re:Irreversible?

[Solandri]

I have a slightly different take on it. Using absolutes like "irreversible" or "unavoidable" is dangerous is because it decreases public support for what you're trying to accomplish. People will think, "well if we can't do anything about it, then I guess there's nothing left to do but live it up in the time we have left."
