	1	+Nuclear power is currently progressing – many reactors are being built with only more planned. Groskopf ‘01/26
	2	+Christopher Groskopf – reporter. “New nuclear reactors are being built a lot more like cars.” Quartz. January 26, 2016. http://qz.com/581566/new-nuclear-reactors-are-being-built-a-lot-more-like-cars/ JJN
	3	+At its birth, nuclear power was a closely guarded national enterprise, only accessible to the most prosperous nations. But over the last 50 years it has evolved into a robust international market with a global supply chain. Not only are more countries starting or considering new nuclear plants, a great many more countries are contributing to their construction. According to data from the International Atomic Energy Agency (IAEA) 66 nuclear reactors are under construction around the world. Dozens more are in various stages of planning. The vast majority of new reactors are being built in China, which has invested in nuclear power in a way not seen since the United States and France first built out their capacity in the 1960’s and 70’s. China’s 2015 Five Year Plan calls for 40 reactors to be built by 2020 and as many as ten more are planned for every year thereafter. Fifteen other countries around the world are also building reactors. The Chinese sprint toward nuclear power is along a path toward becoming a major exporter of nuclear technology and expertise. In addition to adopting western designs, China also has its own reactor designs. Plants based on those designs are also under construction both China and in Pakistan. Other countries are considering them. At the same time China has upgraded its capacity to produce pressure vessels, turbines and other heavy manufacturing components—all of which it is expected to begin exporting. This sort of globalized manufacturing is nothing new: cars, airplanes and most other complicated machines are built in this way. However, it is new for reactors, which must be constructed on-site and rely on highly specialized parts. Those parts must be manufactured to tolerances well beyond what is required in other industries. In some cases even the equipment needed to creating them must be purpose-built. Consider, for example, the steel pressure vessel at the heart of the most common reactor designs. These vessels can only be created in the world’s largest steel presses—some of which exert more than 30,000 pounds of force. The vessels are forged out of solid steel ingots that may weigh more than a million pounds. Until recently there were only a handful of such presses in the world. Today there are at least 23, spread across 11 countries, according to the World Nuclear Association (WNA). Such specialization is not limited to heavy manufacturing. Nuclear reactors require thousands of other mechanical and electronic components, many of which are purpose-made. A brochure from the Nuclear Energy Institute (NEI) identifies hundreds of individual parts. (pdf) Even otherwise common products may need to meet extraordinarily fine tolerances. Standards require that steel elements relevant to safety are manufactured with exceptional “nuclear-grade steel.” According to another NEI list, the construction of a new reactor may require a total of: 500 to 3,000 nuclear grade valves 125 to 250 pumps 44 miles of piping 300 miles of electric wiring 90,000 electrical components According to Greg Kaser, who analyzes supply chains for the WNA, the market for nuclear components has been driven by US-based reactor companies, namely Westinghouse Electric Company. “The US can’t produce everything that’s required for a nuclear reactor anymore, so they have to go international,” Kaser told Quartz. Reactors based on Westinghouse’s AP1000 design are under construction in both the US and China. The parts for these reactors are sourced from all over the world. Many come from European companies that were originally created to supply domestic nuclear programs, but have since become important exporters. This trade in nuclear components is difficult to measure. Despite the specific qualifications of a nuclear-grade valve, it is still a valve and doesn’t necessarily show up in trade statistics as anything more. A great deal of trade is also in expertise. Engineers from China, Japan, South Korea and the United States frequently consult on (or lead) nuclear projects around the world. A 2014 WNA report (paywall) estimates that the total value of investments in new nuclear facilities through 2030 will be $1.2 trillion. But this nuclear globalization has not been greeted with enthusiasm everywhere. The 2011 nuclear contamination disaster at Fukushima, Japan, briefly stalled development of some projects and prompted Germany to begin shutting down all of its reactors. A decision by the UK to allow a Chinese company to develop new nuclear reactors in England has led to both domestic and international hand-wringing over the security implications. Others worry about about safety issues resulting from companies faking the certifications required for selling reactor components. In 2013, two South Korean nuclear reactors were shut down when it was discovered that they had installed cables with counterfeit nuclear certifications. This year the IAEA will update a procurement guide for plant operators that was published in 1996. (pdf) The new version will include a chapter specifically addressing counterfeit components. For the moment, it’s unlikely any of these concerns will be enough to slow the resurgent growth of the global nuclear industry. Though big nuclear companies often speak of localizing the supply chain—and keeping those jobs in their home country—international competition can drive down the price of building a reactor. In fact, the supply chain is likely to become even more important to the construction process in the future. New reactors being designed today are both smaller and more modular, and plans call for large sections of them to be assembled in factories and shipped to the site. If it sounds a lot like the assembly line at a automobile plant, that’s because it is. But of course, one small oversight or production flaw could make a much greater difference.

	5	+Warming is anthropogenic and can be stopped if we reduce emissions. Nuccitelli 8/15

	7	+Dana Nuccitelli 8/15/16 “Climate urgency: we've locked in more global warming than people realize” https://www.theguardian.com/environment/climate-consensus-97-per-cent/2016/aug/15/climate-urgency-weve-locked-in-more-global-warming-than-people-realize
	8	+
	9	+So far humans have caused about 1°C warming of global surface temperatures, but if we were to freeze the level of atmospheric carbon dioxide at today’s levels, the planet would continue warming. Over the coming decades, we’d see about another 0.5°C warming, largely due to what’s called the “thermal inertia” of the oceans (think of the long amount of time it takes to boil a kettle of water). The Earth’s surface would keep warming about another 1.5°C over the ensuing centuries as ice continued to melt, decreasing the planet’s reflectivity.¶ To put this in context, the international community agreed in last year’s Paris climate accords that we should limit climate change risks by keeping global warming below 2°C, and preferably closer to 1.5°C. Yet from the carbon pollution we’ve already put into the atmosphere, we’re committed to 1.5–3°C warming over the coming decades and centuries, and we continue to pump out over 30 billion tons of carbon dioxide every year.¶ The importance of reaching zero or negative emissions¶ We can solve this problem if, rather than holding the amount of atmospheric carbon dioxide steady, it falls over time. As discussed in the above video, Earth naturally absorbs more carbon than it releases, so if we reduce human emissions to zero, the level of atmospheric carbon dioxide will slowly decline. Humans can also help the process by finding ways to pull carbon out of the atmosphere and sequester it.¶ Scientists are researching various technologies to accomplish this, but we’ve already put over 500 billion tons of carbon dioxide into the atmosphere. Pulling a significant amount of that carbon out of the atmosphere and storing it safely will be a tremendous challenge, and we won’t be able to reduce the amount in the atmosphere until we first get our emissions close to zero.¶ There are an infinite number of potential carbon emissions pathways, but the 2014 IPCC report considered four possible paths that they called RCPs. In one of these (called RCP 2.6 or RCP3-PD), we take immediate, aggressive, global action to cut carbon pollution, atmospheric carbon dioxide levels peak at 443 ppm in 2050, and by 2100 they’ve fallen back down to today’s level of 400 ppm. In two others (RCPs 4.5 and 6.0) we act more slowly, and atmospheric levels don’t peak until the year 2150, then they remain steady, and in the last (RCP8.5) carbon dioxide levels keep rising until 2250. As the figure below shows, in the first scenario, global warming peaks at 2°C and then temperatures start to fall toward the 1.5°C level, meeting our Paris climate targets. In the other scenarios, temperatures keep rising centuries into the future We don’t know what technologies will be available in the future, but we do know that the more carbon pollution we pump into the atmosphere today, the longer it will take and more difficult it will be to reach zero emissions and stabilize the climate. We’ll also have to pull that much more carbon out of the atmosphere. ¶ It’s possible that as in three of the IPCC scenarios, we’ll never get all the way down to zero or negative carbon emissions, in which case today’s pollution will keep heating the planet for centuries to come. Today’s carbon pollution will leave a legacy of climate change consequences that future generations may struggle with for the next thousand years.¶ Five years ago, the Australian government established a Climate Commission, which published a report discussing why we’re in the midst of the ‘critical decade’ on climate change:¶ The risks of future climate change – to our economy, society and environment – are serious, and grow rapidly with each degree of further temperature rise. Minimising these risks requires rapid, deep and ongoing reductions to global greenhouse gas emissions. We must begin now if we are to decarbonise our economy and move to clean energy sources by 2050. This decade is the critical decade.¶ Our is the first generation to understand the problems our carbon pollution is causing, and the last that can take the necessary action to prevent them from causing a climate destabilization. In addition to the Australian Climate Commission, 31 major scientific organizations recently warned policymakers that:¶ To reduce the risk of the most severe impacts of climate change, greenhouse gas emissions must be substantially reduced.¶ We have no excuse for inaction or complacency; the experts have clearly warned us. If we refuse to urgently act on this information, future generations will suffer the consequences of our failures today.
	10	+Prohibiting nuclear power means warming can’t be solved – impracticality of renewables combined with a switch to coal only makes warming worse. Harvey ‘12
	11	+Fiona Harvey - award-winning environment journalist for the Guardian, used to work for financial times. “Nuclear power is only solution to climate change, says Jeffrey Sachs.” The Guardian. May 3, 2012. https://www.theguardian.com/environment/2012/may/03/nuclear-power-solution-climate-change JJN *bracketing in original
	12	+Combating climate change will require an expansion of nuclear power, respected economist Jeffrey Sachs said on Thursday, in remarks that are likely to dismay some sections of the environmental movement. Prof Sachs said atomic energy was needed because it provided a low-carbon source of power, while renewable energy was not making up enough of the world's energy mix and new technologies such as carbon capture and storage were not progressing fast enough. "We won't meet the carbon targets if nuclear is taken off the table," he said. He said coal was likely to continue to be cheaper than renewables and other low-carbon forms of energy, unless the effects of the climate were taken into account. "Fossil fuel prices will remain low enough to wreck low-carbon energy unless you have incentives and carbon pricing," he told the annual meeting of the Asian Development Bank in Manila. A group of four prominent UK environmentalists, including Jonathon Porritt and former heads of Friends of the Earth UK Tony Juniper and Charles Secrett, have been campaigning against nuclear power in recent weeks, arguing that it is unnecessary, dangerous and too expensive. Porritt told the Guardian: "It nuclear power cannot possibly deliver – primarily for economic reasons. Nuclear reactors are massively expensive. They take a long time to build. And even when they're up and running, they're nothing like as reliable as the industry would have us believe." But Sachs, director of the Earth Institute and professor of sustainable development at Columbia University in the US, said the world had no choice because the threat of climate change had grown so grave. He said greenhouse gas emissions, which have continued to rise despite the financial crisis and deep recession in the developed world, were "nowhere near" falling to the level that would be needed to avert dangerous climate change. He said: "Emissions per unit of energy need to fall by a factor of six. That means electrifying everything that can be electrified and then making electricity largely carbon-free. It requires renewable energy, nuclear and carbon capture and storage – these are all very big challenges. We need to understand the scale of the challenge." Sachs warned that "nice projects" around the world involving renewable power or energy efficiency would not be enough to stave off the catastrophic effects of global warming – a wholesale change and overhaul of the world's energy systems and economy would be needed if the world is to hold carbon emissions to 450 parts per million of the atmosphere – a level that in itself may be inadequate. "We are nowhere close to that – as wishful thinking and corporate lobbies are much more powerful than the arithmetic of climate scientists," he said.

	14	+Empirically proven in Japan a ban on nuclear triggered a shift to coal. Follett 16
	15	+Follett, Andrew. (Energy and Science Reporter ) "The End Of Nuclear Power In Japan Is Bringing Back Coal." The Daily Caller. June 13, 2016. Accessed September 27, 2016. http://dailycaller.com/2016/06/13/the-end-of-nuclear-power-in-japan-is-bringing-back-coal/. SP

	17	+An analysis published Monday by Bloomberg states that coal power will become the largest source of electricity in Japan due to an effective ban on nuclear power. Nuclear power provided 29 percent of Japan’s total power output before 2011, but will decline to 13.6 percent by 2023 and 1.2 percent by 2040, according to the report. Japan got 24 percent of its electricity from coal in 2010 and the country plans to get more than a third of its power from coal by 2040. Japan previously shut down all of its nuclear reactors in the aftermath of the 2011 magnitude 9.0 earthquake, which triggered the Fukushima disaster. The country has since transitioned away from nuclear power. Prior to the disaster, Japan operated 54 nuclear power plants and the government planned to build enough reactors to provide 50 percent of the country’s electricity power. After the disaster, Japan pledged to effectively abandon nuclear power by the 2030s, replacing it mostly with wind or solar power, causing the price of electricity to rise by 20 percent. The transition to green energy hasn’t gone well and the country likely won’t meet its goals, according to the report. Japan remains a top importer of oil, coal and natural gas and the government estimated that importing fuel costs the country more than $40 billion annually. Japan’s current government sees a revival of nuclear power as critical to supporting economic growth and slowing an exodus of Japanese manufacturing to lower-cost countries, but has faced incredible pushback.

	19	+Warming leads to extinction – multiple scenarios prove. Roberts ‘13
	20	+David Roberts - staff writer for Grist. “If you aren’t alarmed about climate, you aren’t paying attention.” Grist. January 10, 2013. http://grist.org/climate-energy/climate-alarmism-the-idea-is-surreal/ JJN
	21	+There was recently another one of those (numbingly familiar) internet tizzies wherein someone trolls environmentalists for being “alarmist” and environmentalists get mad and the troll says “why are you being so defensive?” and everybody clicks, clicks, clicks. I have no desire to dance that dismal do-si-do again. But it is worth noting that I find the notion of “alarmism” in regard to climate change almost surreal. I barely know what to make of it. So in the name of getting our bearings, let’s review a few things we know. We know we’ve raised global average temperatures around 0.8 degrees C so far. We know that 2 degrees C is where most scientists predict catastrophic and irreversible impacts. And we know that we are currently on a trajectory that will push temperatures up 4 degrees or more by the end of the century. What would 4 degrees look like? A recent World Bank review of the science reminds us. First, it’ll get hot: Projections for a 4°C world show a dramatic increase in the intensity and frequency of high-temperature extremes. Recent extreme heat waves such as in Russia in 2010 are likely to become the new normal summer in a 4°C world. Tropical South America, central Africa, and all tropical islands in the Pacific are likely to regularly experience heat waves of unprecedented magnitude and duration. In this new high-temperature climate regime, the coolest months are likely to be substantially warmer than the warmest months at the end of the 20th century. In regions such as the Mediterranean, North Africa, the Middle East, and the Tibetan plateau, almost all summer months are likely to be warmer than the most extreme heat waves presently experienced. For example, the warmest July in the Mediterranean region could be 9°C warmer than today’s warmest July. Extreme heat waves in recent years have had severe impacts, causing heat-related deaths, forest fires, and harvest losses. The impacts of the extreme heat waves projected for a 4°C world have not been evaluated, but they could be expected to vastly exceed the consequences experienced to date and potentially exceed the adaptive capacities of many societies and natural systems. my emphasis Warming to 4 degrees would also lead to “an increase of about 150 percent in acidity of the ocean,” leading to levels of acidity “unparalleled in Earth’s history.” That’s bad news for, say, coral reefs: The combination of thermally induced bleaching events, ocean acidification, and sea-level rise threatens large fractions of coral reefs even at 1.5°C global warming. The regional extinction of entire coral reef ecosystems, which could occur well before 4°C is reached, would have profound consequences for their dependent species and for the people who depend on them for food, income, tourism, and shoreline protection. It will also “likely lead to a sea-level rise of 0.5 to 1 meter, and possibly more, by 2100, with several meters more to be realized in the coming centuries.” That rise won’t be spread evenly, even within regions and countries — regions close to the equator will see even higher seas. There are also indications that it would “significantly exacerbate existing water scarcity in many regions, particularly northern and eastern Africa, the Middle East, and South Asia, while additional countries in Africa would be newly confronted with water scarcity on a national scale due to population growth.” Also, more extreme weather events: Ecosystems will be affected by more frequent extreme weather events, such as forest loss due to droughts and wildfire exacerbated by land use and agricultural expansion. In Amazonia, forest fires could as much as double by 2050 with warming of approximately 1.5°C to 2°C above preindustrial levels. Changes would be expected to be even more severe in a 4°C world. Also loss of biodiversity and ecosystem services: In a 4°C world, climate change seems likely to become the dominant driver of ecosystem shifts, surpassing habitat destruction as the greatest threat to biodiversity. Recent research suggests that large-scale loss of biodiversity is likely to occur in a 4°C world, with climate change and high CO2 concentration driving a transition of the Earth’s ecosystems into a state unknown in human experience. Ecosystem damage would be expected to dramatically reduce the provision of ecosystem services on which society depends (for example, fisheries and protection of coastline afforded by coral reefs and mangroves.) New research also indicates a “rapidly rising risk of crop yield reductions as the world warms.” So food will be tough. All this will add up to “large-scale displacement of populations and have adverse consequences for human security and economic and trade systems.” Given the uncertainties and long-tail risks involved, “there is no certainty that adaptation to a 4°C world is possible.” There’s a small but non-trivial chance of advanced civilization breaking down entirely. Now ponder the fact that some scenarios show us going up to 6 degrees by the end of the century, a level of devastation we have not studied and barely know how to conceive. Ponder the fact that somewhere along the line, though we don’t know exactly where, enough self-reinforcing feedback loops will be running to make climate change unstoppable and irreversible for centuries to come. That would mean handing our grandchildren and their grandchildren not only a burned, chaotic, denuded world, but a world that is inexorably more inhospitable with every passing decade. Take all that in, sit with it for a while, and then tell me what it could mean to be an “alarmist” in this context. What level of alarm is adequate?
