IPCC Climate Change Report Calls For Urgent Action To Phase Out Fossil Fuels (bbc.com) 478

Posted by BeauHD from the time-is-running-out dept.
The United Nation's Intergovernmental Panel on Climate Change (IPCC) has issued a report that says global temperatures are heading towards 3 degrees C, and that the original goal of keeping the rise under 1.5 degrees C will require "rapid, far-reaching and unprecedented changes in all aspects of society." While the window of opportunity is not yet closed, the prospect looks unlikely and hugely expensive. BBC reports: The critical 33-page Summary for Policymakers certainly bears the hallmarks of difficult negotiations between climate researchers determined to stick to what their studies have shown and political representatives more concerned with economies and living standards. Despite the inevitable compromises, there are some key messages that come through loud and and clear. "The first is that limiting warming to 1.5C brings a lot of benefits compared with limiting it to 2 degrees. It really reduces the impacts of climate change in very important ways," said Prof Jim Skea, who is a co-chair of the IPCC. "The second is the unprecedented nature of the changes that are required if we are to limit warming to 1.5C -- changes to energy systems, changes to the way we manage land, changes to the way we move around with transportation."

"Scientists might want to write in capital letters, 'ACT NOW IDIOTS,' but they need to say that with facts and numbers," said Kaisa Kosonen, from Greenpeace, who was an observer at the negotiations. "And they have." The researchers have used these facts and numbers to paint a picture of the world with a dangerous fever, caused by humans. We used to think if we could keep warming below 2 degrees this century then the changes we would experience would be manageable. Not any more. This new study says that going past 1.5C is dicing with the planet's liveability. And the 1.5C temperature "guard rail" could be exceeded in just 12 years in 2030. We can stay below it but it will require urgent, large-scale changes from governments and individuals, plus we will have to invest a massive pile of cash every year, around 2.5% of global GDP, for two decades. Even then, we will still need machines, trees and plants to capture carbon from the air that we can then store deep underground. Forever! In order to get to 1.5C, the report says the following will be necessary: Global emissions of CO2 need to decline by 45% from 2010 levels by 2030; Renewables are estimated to provide up to 85% of global electricity by 2050; Coal is expected to reduce to close to zero; Up to 7 million sq km of land will be needed for energy crops (a bit less than the size of Australia); and Global net zero emissions by 2050. As if this wasn't demanding enough, the report says that to limit warming to 1.5C, it will involve "annual average investment needs in the energy system of around $2.4 trillion" between 2016 and 2035.

If the planet reaches 2C of warming, coral reefs would be almost entirely wiped out and global sea-levels will rise around 10 centimeters more. "There are also significant impacts on ocean temperatures and acidity, and the ability to grow crops like rice, maize and wheat," reports The Guardian.

      Solar Reserve have some great low externality base load solar power stations.

      It won't work. It can't work. I say this because it uses the same materials for the salt and piping as molten salt nuclear reactors and I've been told the salt will simply eat through the pipes and all you will have is an expensive mess.

      Let's assume this solar salt thermal storage technology does work, then molten salt nuclear reactors will work. Research in one molten salt technology is directly applicable to the other. If these solar thermal plants gain any traction and prove the technology on molten salts then molten salt nuclear reactors will soon follow.

      There's a big difference though between these molten salt technologies, nuclear power doesn't need sunny skies to provide power. The claims of being able to provide power through the night is not what I'm talking about, I mean that the nuclear reactor can run where it cannot ever see the sun. This can be above the Arctic Circle. This can be underground. This can be under the sea. On the moon. On Mars. These solar power collectors need land, and lots of it, for collecting the sun while nuclear does not. I've heard people claim these collectors can be on rooftops or the land underneath can be used for other purposes. I won't dispute this. I only say that the same applies to nuclear power, it can be put underneath anything. It can be under an airport, a military base, or a bunch of solar collectors. Land use is effectively zero for both but the power output per area is very low for solar but nearly unlimited for nuclear.

      The only rational conclusion is that the world is being run by complete anti-social psychopaths who actually want such an outcome, otherwise it would be done already. The excuses are less and less believable every day.

      That's not the only rational conclusion. Another is that the politicians that keep talking of our impending doom unless we do something don't believe their own words. If the powers that be in government believed that if CO2 output from human activity was not reduced dramatically now then they'd be pulling out all the stops on low CO2 energy regardless of the form it took.

      Here's an example, the US Navy wanted some new nuclear powered warships. The Navy already has nuclear powered submarines and aircraft carriers but the use of nuclear powered destroyers and cruisers ended in the 1990s. The Navy wanted new nuclear powered cruisers because they offer advantages beyond simply not burning oil and contributing to the CO2 in the air, such as increased range and the ability to keep fighting without have to take on fuel from a much less battle capable oiler. Congress denied this as a matter of costs. Another example the US Coast Guard wants... that's not right, NEEDS new ice breakers to service scientific missions in Antarctica and to keep shipping lanes open for communities in Alaska, communities including military bases and their families. Congress won't replace the aging and continually in disrepair oil fired ice breakers with nuclear powered versions. Military bases domestically and around the world need reliable power that is not subject to the whims of foreign supplies of oil. Past administrations put up fragile solar collectors and windmills that interfere with radar used to detect incoming missiles and aircraft.

      If these people were serious about solving the problems of reducing CO2 output, providing for energy independence, and assuring the military is effective in defending our national interests, then they'd be building nuclear powered ships and putting nuclear power plants on military bases, airports, seaports, and other vital facilities.

      Perhaps I'm merely arguing the powers that be are a different kind of sociopath, they don't want to solve the problems but merely appear to be working towards those ends. This means a series of half-assed "solutions" that on the surface appear to be a means to make things better but in the

    While the US federal government has a distinct lack of political will change pollution, it is still possible for states to take action that will have a wide effect.

    For example, a state could require an environmental tax on all products (including imports) that are equivalent to the cost the remove the pollution expelled in the production (or use) of the product. They could then use that money to fun CO2 capture systems. Naturally, you would want to ramp this up over a few years as to reduce the economic impact. While the demands of a single state would have a small impact, it would provide the political cover for other states to join in.

    This would soon bankrupt coal power plants and quickly point power companies toward ramping up environmentally friendly power sources lest competition take their profits. So if some state politicians can just grow a pair and do this then we'll be on our way to environmental recovery.

    Good progress is made by the brave, not the cowards who only think of themselves.

      I think the states are handcuffed by Congress' ability to regulate interstate commerce. States can't charge tariffs on imports from other states.

      I honestly don't know how California was ever able to get away with its own emissions standards in the 1970s when up against the Big 3 automakers other than the obvious smog problems in LA making it clear something had to be done.

      States have pretty good options for regulating pollution outputs but they're also often up against the economic realities of the cost of energy as a major factor in their local business economics, and the fact that a lot of power plants are owned by national companies. Force closed a big coal plant without anything to replace its baseload? Sure, but now you've tripled the cost of electricity and it won't be long before local businesses close or relocate because they aren't profitable at the new rates.

      I never know how much of the "solar/wind is growing!!!11" hype to actually believe, but it's probably likely that the economics of it really are starting to make sense and the only way change will really happen is when the economics of it work.

      But... is it?

      Is it ACTUALLY more expensive to not do anything? Certainly, morally, but in terms of actual solutions and their efficacy and the knock-on effects and the cost of implementations - the data is actually thin on the ground.

      The Paris agreement is an example. Even if we all stuck to it, these same research bodies are now saying it's not enough.

      If the cost of not-drowing-in-Waterworld is to actually make many modern conveniences so expensive and unobtainable, have we "won"? Is that "better"? Is people aren't being flooded out of the coastal regions, but nobody can afford their electricity bill, or medicines and oils and products and shipping is suddenly twice as expensive?

      Everyone's done the "cost analysis" of not doing something. Nobody has (realistically) done the cost analysis of actually doing something that might work - or even really suggested what that is.

      It's a huge bugbear to me. The solutions are half-assed casual suggestions ("release less CO2", "stop burning oil"), etc. but the COST of doing so is not just a number on a balance sheet. More old people will die in winter, more things we take for granted won't be practical, and the associated error-bars are HUGE because we just don't know what's going to happen.

      I'm perfectly happy to trust in science and saying yes, this is happening, it's bad, it's caused by us. Let's take that as an "assumption" to work from even if you don't personally believe it.

      Now what? What do we do that fixes it? We stop burning coal. Okay, what would that affect? To my knowledge only one country in the world is coal-free on any regular basis (Germany?), and that's still one of the countries most reliant on coal overall. It's ALWAYS fossil fuels. Then nuclear. Then biomass (trees!). Then all the other "renewable" sources.

      So just a simple statement as "don't burn coal" drastically affects the economy and energy production of every country on the planet. That's going to knock into heating, cooling and industry before anything else. Which is going to kill people (even if only the elderly) and make everything more expensive.

      And that's just one item. Taken together, do the effects of "let's just burn everything, ramp up energy and use that resource to find a better solution" actually kill less or more people over the next 100 years? We don't know. Few ever study the "other side" of the coin.

      The problem with this kind of thing, which I wholeheartedly believe is conveying a necessary message, is that the message boils down to "DO THIS OR DIE!" and then someone in the crowd says "But... if we do that... do we not die anyway? Just in a different way, while destroying industry and society and causing more damage long-term?" And nobody has even the decency to look sheepish or say "Well, no, actually we looked and it wouldn't hurt at all if we did X instead".

      The research into that side might exist, but it's certainly not being advertised and not being made popular and almost certainly not being done as rigorously or as seriously as the scaremongering.

      I'd honestly like to know - if we do EVERYTHING - if we all get unanimous worldwide co-operation and overnight we all become vegans who wash their clothes on rocks, solar-power the entire world, never burn so much as a match again, pump all our energy resources into reversing the CO2 increase, recycle every plastic bag in every landfill in the planet, etc. etc. etc. - whatever loony ideas we can come up with - will that *actually* make it better than the alternative? Because I see drastically little evidence that way. I know we all say "it's there, it's what the scientists say"... but as I consider myself a scientist, I can't honestly look and say "I must recommend this path, or indeed ANY path, out of this mess, because it will be better than the thing we think might happen if we don't".

      Everyone acknowledges the problem. The solution eludes us. And the cost-benefit analysis of any dream we can imagine is really "Er... dunno... probably not" at best.

        Everyone acknowledges the problem. The solution eludes us.

        Marine cloud brightening [wikipedia.org].

        And the cost-benefit analysis of any dream we can imagine is really "Er... dunno... probably not" at best.

        Ocean rise is currently the biggest economic impact, since so many people live on the coast. So keeping track of ocean levels is key.

      • Everyone acknowledges the problem. The solution eludes us.

        The solution does not elude us. I've listened to many experts on energy and they all agree on several key points.

        First key point, more nuclear power. Nuclear power is safe, costs are less than wind and solar, reliable, and has lower CO2 emissions than any other energy source we have. The nuclear power plants we have now are getting old and will need to be replaced. We will need to start building nuclear power reactors now so when it's time to retire these old reactors we have something to take their pla

      They've been saying stuff like that for years and it never comes true. We humans are a genious bunch when it comes to survival. What scientist need to do is find an economic solution to the problem. What really is an affordable, acceptable solution? So far all we've heard is either limit reproduction severely (a la China's one child policy - that worked out great) or kill people en masse/let yourself be killed. The other alternatives are mass production of inobtainium and going back to a pre-industrial era

    If such a person existed, he/she could organize a grand climate Panmunjom.

    The right would have to admit that the greenhouse mechanism is plausible and that current data shows warming. There may be disagreement about exactly how much there is and at what point 'weather' becomes 'climate,' but it's out there, and growing.

    The left would have to allow us to use all carbon-free technologies in addressing the problem, rather than just the ones that are tiny and cute. In the real world, we still need energy-usinh big cities and heavy industries.

  • The current generation of leaders is going to leave an absolute garbage dump of a planet to the next generation--the Millennials.

    Think I'm exaggerating? Australia just recently gave up [independent.co.uk] on its effort to meet its Paris climate agreement carbon reduction targets.

    Spin a giant fresnel lens (or simply a diffuser) at L1 to shade the earth, like was already suggested in 2004 by Gregory Benford. He said you could use plastic, but I have my doubts that would survive very long. Aluminium oxide maybe? L1 delta v isn't much higher than LEO, so with SpaceX costs this should be doable for 10s of billions in lift cost.

    A fraction of the opportunity cost of destroying the global economy and triggering WW3.

  • This is the massive threat to humanity we've seen in sci-fi movies, usually represented by an invading alien species or some massive natural(ish) disaster, but in real life it was our own pollution that first posed a huge threat to us all.

    And now we see how we react as a species to that threat. We didn't temporarily put aside our differences to work toward a common goal as fiction has often speculated. Instead most people kind of brushed the problem off and went back to focusing on the small-scale problems in their own lives, and a few people convinced themselves that the threat was made up and we'd all be fine. When we already had a good idea of how dangerous this threat was, those people elected a raging moron who shared their collectively suicidal beliefs to what was at the time the most powerful political office in the world.

    The biggest threat to humanity is ourselves. Working to optimize our societies into what is effectively a perfect breeding ground for psychopaths over the last few hundred years (and especially over the last few decades) has been biting us in the ass the entire time and is about to finally rip out our throats.

    I think our only hope is a millennial-driven political revolution - vote out every conservative everywhere across the globe, and put something between social democrats and democratic socialists in power so we can refocus our societies on benefiting as much of humanity as possible and defeat the incredibly short-sighted and largely detrimental business interests driving us to collective ruin.
